He reveals a hard numeric cutoff from 6,000+ patient studies: no woman with an SHBG (sex hormone binding globulin) above 170 ng/dL experienced a positive sexual response to testosterone therapy, making SHBG measurement essential.
3
Dr. Simon advocates 'outercourse'—preserving intimate touch, oral sex, and mutual pleasure without penetrative intercourse—for couples facing erectile dysfunction, hip arthritis, or painful penetration, so they don't abandon sex entirely.

Treat pain before addressing desire
WhatFix vaginal pain, dryness, or GSM with local therapies before initiating testosterone or other libido-focused treatments.
WhenAt the first evaluation of low sexual desire; screen for pain.
DoseDepends on therapy: vaginal estrogen tablets/creams/ring, DHEA inserts, or ospemifene. Start with lowest effective dose; maintenance often required long-term.
For whomAll women with low desire who have any component of dyspareunia or vaginal atrophy.
WhyNobody wants sex if it hurts. Treating pain is foundational; increasing desire with testosterone when there is pain is counterproductive and cruel.
CaveatsVaginal treatments take weeks to months to fully restore tissue; some women need combination therapy. If pain is due to pelvic floor hypertonus, hormonal therapy alone is insufficient.
Dr. Simon strongly emphasizes a sequence: treat pain first, then address desire. He makes the analogy that a woman who avoids sex due to pain is like someone who avoids touching a hot stove—she is in touch with her body and needs the pain removed, not her desire pathologized. In his clinic, patients are screened before they come through the door for pain, desire level, and other factors. He often starts with local vaginal estrogen, DHEA, or ospemifene to restore tissue health. Only after the vagina is 'fixed' does he consider systemic testosterone for desire. He also notes that many pleasurable sexual activities do not involve painful penetration, and couples should remember those.
Mechanism
Vaginal estrogen/DHEA/ospemifene reverse GSM by restoring epithelial thickness, vascularity, lubrication, and reducing local inflammation, thereby eliminating pain with penetration. Testosterone acts primarily on central desire pathways and does not directly heal atrophic tissue.
Personal experience
The last thing I want to do is increase someone's desire who's having pain.
A woman who doesn't want to have sex is because she's having pain, that's someone that is in touch with her body and she just needs her pain fixed. It doesn't mean that she can't have sex, it just means she can't have painful aspects of sex.
Also said
“If the vagina's broken, we need to fix that, you know, and so vaginal estrogen or whatever she needs before we kind of get to the testosterone piece of the puzzle.”— Reinforces the order of operations.
Testosterone therapy for female HSDD
WhatPrescribe testosterone (off-label, microdosing men's gel or cream) for hypoactive sexual desire disorder in women, targeting total testosterone levels of 20–80 ng/dL.
WhenAfter menopause, once pain and vaginal atrophy are treated, for women with persistent low desire. Consider earlier if surgically menopausal.
DoseMicrodose men's testosterone gel (e.g., AndroGel) to achieve serum total testosterone 20–80 ng/dL (ideally 30–60). Doses often 1/10th of male dose; adjust based on labs and clinical response.
For whomPostmenopausal women with HSDD, especially those with bilateral oophorectomy, who have no contraindications. Confirm SHBG <170 for likelihood of response.
WhyTestosterone is the hormone of desire for both sexes. Clinical trials show improvements in desire, arousal, orgasm, and sexual self-image when levels are restored to premenopausal physiologic range.
CaveatsNo FDA-approved female formulation; must use off-label male products microdosed. Monitor for androgenic side effects: hirsutism, voice deepening, acne, hair loss if levels exceed 80–100 ng/dL. Cardiovascular concerns largely dispelled for physiologic levels. Use LCMS/GCMS lab testing, not standard male assay. If SHBG high, lower it first.
Dr. Simon has extensive experience in testosterone research, including the development of two failed FDA products. He explains that the best evidence is for sexual desire, particularly in oophorectomized women, with secondary benefits on arousal, orgasm ease and intensity, and sexual self-image. He describes the SHBG 170 cutoff as a key learning from the patch trials. He walks through the jigsaw puzzle analogy for emerging data on mood, energy, body composition, and bone density—tantalizing pieces but not yet a complete picture at physiologic doses. He notes that some women seeking these off-target benefits are pushed to supraphysiologic (male-range) levels, which increases risk of irreversible virilization. He remains hopeful that an FDA-approved product will come soon, citing recent approvals in Australia, NZ, South Africa, and the UK.
Mechanism
Testosterone binds androgen receptors in the brain (hypothalamus, limbic system) to increase sexual motivation and spontaneous desire. It also enhances genital vasocongestion and sensation, possibly via nitric oxide pathways. SHBG binds testosterone, reducing free active hormone.
Personal experience
We were actively involved in developing two different testosterone products for women, both of which failed at the FDA... And so in the absence of an FDA-approved product for women, we're you know, microdosing or flying by the seat of our pants.
The best and most abundant scientifically proven information is about sexual desire. It's documented best in women who had their ovaries removed... It helps tip them in the direction of yes, let's go.
Also said
“Those levels are typically 20 to 60, 80 ng/dL. You don't need to know the units. 20 to 80 is a good enough number. But if you start pushing above 80, particularly above 100, you start getting hairy in places where men are naturally hairy and women tweeze, tease, pull, pluck, laser, etc.”— Gives the safety window for dosing.
“The quick and dirty testosterone tests that are easy to order were designed for measuring testosterone in men. They are not good enough to measure testosterone in women... these are testosterone measurements that are called LCMS or GCMS.”— Directs practitioners to the correct lab method.
Vaginal maintenance ladder for GSM
WhatUse local vaginal estrogen (tablets, cream, ring), DHEA inserts, or oral ospemifene to treat and prevent genitourinary syndrome of menopause, with a preference for consistent maintenance over crisis intervention.
WhenStart when women enter menopause, ideally 5+ years before vaginal symptoms typically peak (around age 60). Can be started at first sign of dryness or pain.
For whomAll menopausal women, especially those with symptoms of dryness, dyspareunia, recurrent UTIs, or vaginal tissue atrophy. Women reluctant to touch their vagina may prefer the oral SERM ospemifene.
WhyIt is easier to maintain vaginal health than to restore it. GSM leads to tissue thinning, dryness, dyspareunia, and increased UTI risk. These treatments estrogenize the tissue, restore elasticity and microbiome, and reduce infection.
CaveatsVaginal estrogen is very low systemic absorption; box warning applies but many experts consider it outdated and minimal risk. Ospemifene is a SERM with a tiny thromboembolic risk similar to other SERMs; it is the only oral option specifically approved for both dyspareunia and 'walking around' dryness. DHEA adds local testosterone effect on vestibule.
Dr. Simon notes that hot flashes typically peak in the first 0–5 years after menopause, but vaginal symptoms tend to appear about 5 years later, around age 60. He stresses that maintaining tissue with early treatment is key, because once atrophy sets in, restoring it is harder. He lists options: vaginal tablets, inserts, rings, creams, the oral SERM ospemifene, and DHEA inserts. He highlights that ospemifene is particularly useful for women who dislike touching their genitals or find topicals messy; its once-daily pill has good adherence and is on the lower end of cost. He also mentions that ospemifene is approved for dryness unrelated to sex (general vaginal dryness), which not all local products are. OTC hyaluronic acid and moisturizers are acceptable for mild symptoms, but when UTIs or significant pain begin, he moves to prescription hormones.
Mechanism
Estrogen receptors in the vaginal epithelium, vasculature, and connective tissue regulate cell proliferation, glycogen production (maintaining a healthy acidic microbiome via lactobacilli), and collagen content. DHEA provides additional local androgen receptor activation in vestibular tissue.
It's easier to maintain vaginal health than to restore it.
Also said
“Believe it or not, there are a subgroup of women who, for whatever reasons, don't want to touch down there, feel down there, put stuff in their vaginas. They find them goopy, messy, junky, dirty, whatever. And they can take care of their vaginas with one pill a day.”— Addresses adherence issue and positions ospemifene as alternative.
“The women who have the most vaginal or vulvar issues, it's about 5 years later. So, they're approaching age 60. If they're not on systemic hormones before they have those symptoms and they come out of the clear blue... either preventing or treating with one of those therapies is great.”— Explains the timeline and the case for prevention.
Pelvic floor physical therapy with internal work
WhatRefer patients with pelvic floor hypertonus or hypotonus to a specialized pelvic floor physical therapist who performs internal manual therapy (vaginal and possibly rectal).
WhenWhen a woman has pain with penetration, inability to fully empty bladder, constipation, or loose pelvic floor contributing to arousal/orgasm issues. For hypertonus, often seen in avid exercisers.
DoseTypically a series of weekly sessions for several months, with home exercises.
For whomWomen with dyspareunia, urinary voiding dysfunction, or pelvic organ pressure. Especially those who do intense core work. Also postpartum women or those with large babies causing hypotonic floor.
WhyTight pelvic floor muscles cause pain, urinary retention, and constipation; loose ones impair sensation and orgasm. PT can teach conscious relaxation or strengthening while maintaining function.
CaveatsMust find a PT who does internal work; external-only therapists are not sufficient for these issues. Hypnotic floor needs strengthening without over-tightening, so careful programming is needed.
Dr. Simon describes how modern fitness (Pilates, crunches) can pull the pelvic floor up into a chronically tight state. He uses the paper bag analogy: the abdominal wall and pelvic floor are connected; tightening the front pulls the bottom. He describes examining women who have just voided and finding their bladder still full because they cannot relax. He strongly advocates for pelvic floor physical therapists who do internal work, inserting fingers to release trigger points and teach patients to voluntarily relax during attempted penetration or voiding. For the opposite problem—hypotonic floor from large babies or weight loss—PT strengthens muscles without overdoing it. He calls these PTs the 'unsung heroes of women's sexual health.'
Mechanism
Pelvic floor muscles under voluntary and autonomic control. Hypertonus is a state of excessive resting tone, where muscle fibers are chronically contracted, causing myofascial pain and restricting blood flow and mobility. Manual release and biofeedback retrain the nervous system to lower tone. For hypotonus, progressive resistance training increases muscle bulk and strength.
Personal experience
I think it's very important that pelvic floor physical therapist has to be one that does internal work, meaning she is likely or willing to put her therapeutic hands, fingers in vaginas, in anuses, etc.
Enter Pilates, yoga, hiking, biking, our current model of feminine fitness, where the pelvic floor is now very tight because we want it tight... So, we need to send her for pelvic floor physical therapy to learn to keep those nice tight abs she's been working so hard on, and at the same time relax her pelvic floor when she pees, when she poops, and when she has sex.
Also said
“Too tight a pelvic floor typically pain, difficulty with penetration. Too loose a pelvic floor difficulty with arousal and orgasm, even though penetrative pain is typically not part of that.”— Summarizes the two opposite presentations.
Couples communication: 'I' language and non-face-to-face dialogue
WhatTeach couples to discuss sexual needs using 'I' statements rather than blaming 'you' statements, and to have these conversations outside the bedroom, not looking directly at each other (e.g., walking hand-in-hand or while watching TV).
WhenAt the start of therapy or when couples report sexual stagnation, resentment, or communication breakdown.
DoseAs needed; a single coaching session to introduce the tool, then practice.
For whomAny couple where sexual communication is stuck or avoidance is present.
WhyFace-to-face confrontation is perceived as aggressive in humans and animals. Blaming language triggers defensiveness. 'I' language reduces aggression and promotes collaboration.
CaveatsRequires both partners' willingness. The practitioner should also arrange office seating so couples don't face each other if tensions are high.
Dr. Simon illustrates the damage of blaming language: if a woman says 'You hurt me every time you put your penis inside,' it is damning and aggressive. Instead, she should say 'Honey, I really like it softer.' He recommends having these conversations outside the bedroom, in a neutral environment, while doing something that avoids direct eye contact—like walking together, sitting on the couch watching TV. In his office, he arranges chairs so the couple looks at him, not at each other, to de-escalate. He notes that when a couple voluntarily sits facing each other, it signals conflict and he has to work to diffuse before he starts. This body language and communication technique is part of his biopsychosocial approach.
Mechanism
Direct eye contact activates threat-detection circuits in the amygdala. Indirect gaze while sharing vulnerable content reduces perceived threat. 'I' statements frame the conversation around one's own experience, which is less provocative than accusatory 'you' statements, decreasing partner defensiveness and cortisol.
Personal experience
Couple comes in and they face their chairs looking at each other, I'm in trouble as a practitioner. ... I got a hole before I even get to flat ground.
Walking hand in hand, looking straight ahead, 'Honey, I'd really like to talk about our sex life.' Not threatening. Eye language and looking away.
Also said
“If I look at you, Mary Claire, and say 'You hurt me every time you put your penis inside.' That's pretty damning. And aggressive. In animals, including humans, face-to-face confrontation is aggressive.”— Vivid example of what not to do.
Erectile dysfunction management for men in the couple
WhatIdentify and treat ED in male partners with PDE5 inhibitors (Viagra, Levitra, Cialis, Stendra), testosterone if low, and ensure psychological support, as ED in the man often exacerbates or creates pain/avoidance in the woman.
WhenWhenever a couple's sexual difficulties involve the male partner, especially if the woman's pain made him lose confidence or develop secondary psychogenic ED.
DosePDE5 inhibitors as needed prior to sex; testosterone replacement to achieve eugonadal levels. Treat underlying conditions like diabetes, hypertension, smoking.
For whomMale partners in the couple with any degree of erectile insufficiency, whether primary or secondary.
Why50% of 50-year-old men have some ED, rising to 80% of 80-year-olds. Unrecognized ED leads to painful intercourse for the woman (weak erections can cause penile injury and Peyronie's) and can be misinterpreted as rejection.
CaveatsMen are vain and may resist. Weak erections are worse for him because he risks physical penile damage if intercourse is forced. PDE5 inhibitors are very effective but not in all men (e.g., diabetes, vascular disease). Must also check and treat testosterone deficiency.
Dr. Simon emphasizes that erectile dysfunction is extremely common and age-related, and that many couples stop sex because of it. He warns women that intercourse with a non-rigid penis can actually cause penile fracture or Peyronie's disease, so forcing the issue is harmful to both. He says men often act as if they're still 20, but they're not, and urges them to accept treatment. He notes that sometimes, the man's ED only begins after he fears hurting his partner, and that creates a cycle: her pain → his anxiety → his ED → less intimacy → more resentment. Breaking that requires treating both partners.
Mechanism
Erectile function relies on adequate vascular inflow and nitric oxide signaling. PDE5 inhibitors slow cGMP breakdown, potentiating vasodilation. Testosterone maintains nitrergic nerve function and endothelial health.
Intercourse, penis and vagina intercourse, with a person who has a non-erect, weak-erect penis is actually worse for him than it is in terms of the sexual encounter because she or they can end up with a broken penis that then becomes either Peyronie's, a curved penis, or one that can't properly attain and maintain an erection.
Also said
“50% of 50-year-old men have some degree of erectile dysfunction. 60% of 60-year-olds, 70% of 70-year-olds, 80% of 80-year-olds.”— Gives the concrete prevalence numbers.
“Don't give up sex. You want to have sex? Great. ... Viagra, Levitra, Cialis, Stendra, all these drugs men have and they can treat erectile dysfunction in a high percentage of men of almost any age.”— Directly encourages treatment.
Measure total testosterone and SHBG in women
WhatOrder total testosterone via LCMS/GCMS (not standard assay) and SHBG to assess androgen status and likely treatment response before prescribing testosterone.
WhenWhen evaluating a woman for testosterone therapy for low desire or other potential androgen-related issues.
DoseOne-time labs at baseline, with periodic monitoring on treatment.
For whomAll women being considered for off-label testosterone.
WhyStandard testosterone assays are inaccurate in women's low range. SHBG above 170 predicts non-response, potentially saving time and side effects.
CaveatsNot all labs can run LCMS/GCMS; use national labs like LabCorp or Quest. Free testosterone is expensive and often unnecessary; total testosterone plus SHBG is sufficient.
Dr. Simon educates that the quick, easy testosterone test designed for men is inaccurate in women. He directs practitioners to order testosterone by LCMS or GCMS, available at major national labs. He explains that he orders total testosterone and SHBG, and that gives him enough information without needing the more expensive free testosterone. He references the SHBG 170 cutoff discovered in the testosterone patch trials. This is the protocol he follows before initiating therapy.
Mechanism
LCMS/GCMS (liquid chromatography mass spectrometry/gas chromatography mass spectrometry) directly measures testosterone molecules with high sensitivity and specificity in low ranges, unlike immunoassays which cross-react.
The quick and dirty testosterone tests that are easy to order were designed for measuring testosterone in men. They are not good enough to measure testosterone in women... the big national laboratories like LabCorp and Quest Laboratories have those assays and you can get a good number for women.
Also said
“So, I'm less concerned about free testosterone because it turns out it's very expensive for many patients and difficult to measure. It can be measured, sometimes I measure it. But, a total testosterone and SHBG gives me enough information.”— Simplifies the lab evaluation.

shbg-170-threshold
mid-late episode
Dr. Simon states that from the testosterone patch development studies, no woman with an SHBG level of 170 ng/dL or higher experienced a sexually positive response to testosterone therapy, providing a concrete clinical cutoff for futility.
Why this matters: This is a specific, data-driven number derived from over 6,000 patients, far more precise than typical vague advice about SHBG. It directly guides when not to prescribe testosterone.
Background
Previously, clinicians knew high SHBG could blunt testosterone's effect, but lacked a clear actionable threshold. This number comes from the manufacturer's own trial data.
Dr. Simon explained that many menopausal women have elevated SHBG, either naturally or from decades of birth control pill use, which binds testosterone and makes it inactive. In the development trials for the testosterone patch, researchers had hormone levels on all participants. When they stratified by SHBG, they found that women with an SHBG of 170 or higher had no positive sexual responses—zero out of roughly 6,000–7,000 women. This finding is so powerful that he uses a total testosterone plus SHBG to make clinical decisions. He notes that SHBG can be lowered fairly easily, suggesting that sometimes lowering the SHBG is all that's needed before adding testosterone.
If you go back into the testosterone patch development studies, we had hormones on all of them, and there were no positive sexually positive responses in any woman, any woman on those testosterone patches that had an SHBG 170 or higher. Zero out of I don't know, 6, 7,000.
Also said
“So, many of your listeners and many of our patients have low sex drive in menopause because they have very high sex hormone binding globulin, either because they just naturally have high sex hormone binding globulin or they've spent, you know, their reproductive lives on birth control pills which raise sex hormone binding globulin.”— Explains why SHBG is often high in this population.
“And so, if a patient has a high SHBG, and I've seen them in the you need to drop it down. And that's a really easy, quick and dirty way to get it down.”— Adds the actionable note that high SHBG can be lowered.
sexual-script-and-erotic-surprise
early-mid episode
Dr. Simon has couples write down their sexual script separately, reveals it's the same 90% of the time, then assigns each partner to plan an 'erotic surprise'—a small twist—to reintroduce novelty without threatening familiarity.
Why this matters: It's a concrete, in-office intervention that reframes the 'boring sex in long-term relationships' problem as a fixable script issue, not a loss of attraction.
Background
Many couples fall into a repetitive sexual routine that extinguishes desire. Common advice to 'spice things up' is vague; this provides a structured method.
Dr. Simon describes how, in long-term relationships, couples unconsciously develop a sexual script: he does A, she does B, then they proceed through a predictable sequence ending in intercourse. The script becomes boring, like eating at the same restaurant every single day. In his practice, he has each partner write down the step-by-step script on separate pieces of paper. He then compares them, and nine out of ten times they are identical—both know exactly what happens. He gives them back the scripts to show them how predictable it is. Then he tasks them: if they have sex weekly, each takes turns planning an 'erotic surprise'—just a small twist in the plot, not something too strange or threatening. If that fails, he tells them to rewrite the whole script and give it to the other person to enact. He also urges them to recall the early days of dating when kissing, touching, and foreplay happened without the immediate goal of intercourse, to bring that anticipation back.
Personal experience
I actually have them write it out, by the way. Okay? Separately, two different pieces of paper, write out what happens step by step in the bedroom... I compare notes. It's the same. Nine times out of 10, it's exactly the same.
So what happens to couples is they develop a sexual script... It's boring. It becomes even more boring. It becomes eating at the same restaurant every single day. Got to change it up.
Also said
“Then, you got to plan an erotic surprise. So, if they have sex once a week... You first, you second, you third, you fourth, you have to plan an erotic surprise. It's in the script. It's not too strange... Just a twist in the plot.”— Provides the exact homework assignment.
“When you first got together, you didn't just take off all your clothes and get in bed and have sex... There's kissing first. Then there's touching. Then there's something else... try and get back there because there was excitement. There was novelty.”— Gives the 'return to foreplay' version of the intervention.
outercourse-as-alternative-to-intercourse
late episode
Dr. Simon advocates 'outercourse'—all intimate and sexual activities short of penis-in-vagina intercourse—as a sustainable model for aging couples when intercourse becomes too difficult, so they don't abandon intimacy entirely.
Why this matters: Reframes the loss of intercourse not as the end of sex but as an opportunity to rediscover the broader sexual repertoire that existed before intercourse became the default endpoint.
Background
Traditional sexual scripts equate 'real sex' with intercourse. When physical limitations (ED, arthritis, vaginal atrophy) make that impossible, many couples stop all physical intimacy, leading to emotional distance.
Dr. Simon explains that in every long-term couple, a time may come when penetrative intercourse becomes more trouble than it's worth. For example, a woman with severe hip arthritis may not be able to spread her legs, or a man with diabetes and vascular disease may not achieve a rigid enough erection for penetration. Often both partners then assume sex is over. Dr. Simon defines outercourse as everything from kissing to genital kissing, manual pleasuring, oral sex, and other forms of mutual pleasure leading to orgasm—everything short of PIV. He notes that both partners can reach orgasm without intercourse, even the man without a full erection. The key is to help couples remember that earlier in their relationship, they engaged in all these activities before intercourse became the routine conclusion, and they can still be satisfying and intimate.
Personal experience
This is my new bandwagon. ... In every couple there comes a time when intercourse can become more trouble than it's worth. That doesn't mean they have to give up on intimacy. ... Let's get back to sexual play, sexual touching, other forms of intimacy because what was ... the epitome, the end goal can now be supplanted by or replaced by other things, both of which can lead to orgasm.
For that couple intercourse may be not possible. It doesn't mean that all the things that they used to do, what I'm defining as outer course, which could be anything from kissing to genital kissing and pleasuring to everything else in the sexual armamentarium short of penis and vagina intercourse, what happened all that stuff?
Also said
“Even he can have an orgasm without a good erection. She can have an orgasm without intercourse for sure.”— Directly dispels the myth that erection and intercourse are required for orgasm.
“And the answer is sometimes all of that goes to waste or settles into the background when neither of them wanted to just because they can't have what historically has been the end of their sexual activity, intercourse.”— Captures the emotional consequence of not considering outercourse.
pelvic-floor-hypertonus-from-fitness
mid-late episode
Dr. Simon highlights that the popular emphasis on core strength—Pilates, heavy crunches, intense abdominal work—can over-tighten the pelvic floor, leading to pain with penetration, constipation, and incomplete bladder emptying, requiring specialized pelvic floor PT to learn relaxation.
Why this matters: Runs counter to the 'strong pelvic floor' messaging and explains why some very fit women develop sexual pain and urinary retention—a problem often misattributed to low estrogen.
Background
Public messaging encourages Kegels and core work to improve continence and sexual function, but excess tension (hypertonus) is an under-recognized cause of pelvic pain and dysfunction.
Dr. Simon explains that human pelvic floors are a sling of muscles at the bottom of the bony pelvis, fighting gravity because we walk upright. Modern fitness culture emphasizes a tight core: Pilates, crunches, heavy lifting. He uses the analogy of a paper bag where the abdominal wall and pelvic floor are connected sides and bottom; tightening the front (abs) pulls up on the floor, increasing pelvic floor tightness. While some tightness is good, hypertonus prevents the muscles from relaxing—necessary for comfortable penetration, urination, and defecation. In his gynecologic exams, he routinely finds women who have just emptied their bladder but still have significant urine in it because their overactive pelvic floor blocks complete voiding. These women benefit from pelvic floor physical therapy with a specialist who does internal work, teaching them to maintain abdominal strength while deliberately relaxing the pelvic floor.
Personal experience
You and I might see a woman who just emptied her bladder for her annual exam, and we do her internal exam, she's got a urine-full of a bladder-full of urine. She just emptied it. Cuz she's not capable of completely emptying cuz her muscles are so tight.
Think of the abdominal and pelvic floor muscles as a paper bag at the grocery... if you tighten the front doing a lot of good crunches, a lot of good core work, heavy weights in your Pilates, the answer is it's going to pull up on the floor, the bottom of that bag, and increase the pelvic floor tightness, which could be good unless she can't relax it.
Also said
“Women have the added problem of keeping the gas, the stool, and the urine in while they're relaxing their vaginas to let their partners in. That's complicated.”— Illustrates the dual demand on pelvic floor.
“It's going to pull up on the floor, the bottom of that bag, and increase the pelvic floor tightness, which could be good unless she can't relax it. It's too tight. If it's too tight, she tends to become constipated, retains urine.”— Links hypertonus to specific non-sexual symptoms.
dhea-vestibule-testosterone
mid episode
Dr. Simon explains that DHEA vaginal inserts convert locally to both estrogen and testosterone, with the testosterone component acting specifically on the vaginal vestibule—an embryonic male remnant that responds to androgens—providing unique benefit beyond estrogen alone.
Why this matters: Many clinicians and patients think of vaginal DHEA only as an estrogen source; the added testosterone effect on the vestibule is rarely discussed and explains why some women respond better to DHEA than to estrogen alone.
Background
Vaginal DHEA (prasterone) was developed by Dr. Fernand Labrie and approved for dyspareunia. Its mechanism of local conversion to both estrogens and androgens is known but not widely detailed in patient education.
Dr. Simon recalls working with Dr. Fernand Labrie on the development of vaginal DHEA. He explains that DHEA, a pre-hormone from the adrenal gland, is converted within the vaginal tissue to both estrogen and testosterone. The estrogen addresses dryness, elasticity, and tissue fragility, while the testosterone acts on androgen-responsive elements of the vulva and particularly the vestibule (vaginal opening). He notes that embryologically, both sexes start with female-appearing anatomy; the tissues that would become the penis in males remain as the clitoris and vestibule in females. The DHEA inserts were intentionally sized to allow a small amount of leakage onto the vestibule, providing both physical emollient properties and local testosterone to tissues that are evolutionarily homologous to male structures and still responsive to androgens. This dual action makes DHEA uniquely suited for some women whose symptoms are not fully relieved by estrogen alone.
Having a little testosterone, particularly on the vaginal opening, the vestibule, is really important. And some women need it directly applied to the vestibule, and some of them can get enough to the vestibule because the size of those DHEA inserts were determined to have a little leakage, a little leakage, to the vestibule to act both because of the emollient properties of the product itself, and also from the testosterone on the vestibule, which is a male remnant in adult women.
Also said
“DHEA stands for dehydroepiandrosterone... an adrenal adrenal hormone that is converted, in this case converted from those vaginal inserts, in the vaginal tissue to both estrogen and testosterone.”— Clearly states the dual conversion mechanism.
“When we're in our mom's womb, up until her mom's second missed period, we are identically anatomic... And the female maintains some of that ambiguity into adulthood. So, they have some parts that would have become penises, had they been boys, and those parts respond to testosterone.”— Explains embryologic basis for androgen sensitivity of vestibule.

ISSWSH Fall Course (International Society for the Study of Women's Sexual Health)
Service
Dr. Simon, when asked what resources he recommends for clinicians who lack sexual medicine training, immediately points to the ISSWSH fall course as where practitioners can learn everything needed to intervene in a couple's treatment.
Dr. Simon explains that ISSWSH hosts an annual fall course covering the full biopsychosocial spectrum of women's sexual health: starting with the sexual response cycle and progressing to secondary treatments for complex disorders. He acknowledges that the amount of material can feel like 'drinking from a firehose,' but it provides a comprehensive foundation that fills the training gaps in primary care, OB/GYN, and urology. Beyond the course, he recommends finding a like-minded community practitioner—pelvic floor PT, sex therapist, psychiatrist—and building a referral network. He also notes that there are many good books on different aspects of sexual medicine, but does not name specific titles.
vs alternatives
Compared to self-study or scattered CME, the ISSWSH course is a concentrated, society-vetted curriculum that also offers a network of specialists via their listserv.
Personal experience
If you're a practitioner, the International Society for the Study of Women's Sexual Health, ISSWSH, has a fall course every fall. We just had it where you are going to learn everything you need to know to intervene in a couple's treatment.
ISSWSH has a fall course every fall... you are going to learn everything you need to know to intervene in a couple's treatment. Primary care, obstetricians, gynecologists, even some specialists, urologists, the whole gamut, you'll learn even though it'll probably feel like drinking from a water from a firehose.
Also said
“There are multiple societies, each of them have their own listserv of practitioners. So, ISSWSH has one...”— Adds the ongoing practitioner directory benefit.
Dr. Simon repeatedly emphasizes the critical role of pelvic floor physical therapists who perform internal manual work for women with sexual pain, hypertonus, or hypotonus.
He clarifies that not all pelvic floor PTs are alike: the therapist must be willing and skilled in internal vaginal (and sometimes anal) manual therapy to release trigger points and re-educate the muscles. External-only therapists who work on abs and back are insufficient for sexual dysfunction. He finds them invaluable for teaching women to consciously relax a tight pelvic floor while maintaining core strength, and for strengthening a hypotonic floor without causing hypertonus. He describes them as the 'unsung heroes of women's sexual health.'
vs alternatives
Compared to Kegel-only advice or external PT, internal work directly addresses myofascial restrictions and neuromuscular re-education that contribute to dyspareunia and voiding dysfunction.
Personal experience
I think it's very important that pelvic floor physical therapist has to be one that does internal work, meaning she is likely or willing to put her therapeutic hands, fingers in vaginas, in anuses, etc.
These pelvic floor physical therapists who are highly specialized are just the unsung heroes of women's sexual health. And the more we can talk about them and and, you know, drive more patients there, I think the better off women are.

“There are some physical therapists who don't do only do external work on abs and back and shoulders and neck and things. They're not the right physical therapist for the women we're talking about, but those that do internal work are incredibly helpful.”— Draws the crucial distinction between therapist types.
Dr. Simon describes ospemifene as a once-daily oral pill that estrogenizes vaginal tissue, approved for both dyspareunia and walking-around-dryness, and particularly useful for women who do not want to touch their genitals or use messy topicals.
He positions ospemifene as an underutilized option in the vaginal health ladder. Unlike vaginal products that require insertion, the oral pill circumvents issues of goopiness and mess. He notes that adherence is better than topical treatments and cost is on the lower end. A key advantage is that ospemifene is specifically approved for general vaginal dryness (unrelated to sex), while many local treatments are only approved for dyspareunia. He mentions a small thromboembolic risk consistent with other SERMs, but within an acceptable risk-benefit profile for appropriate patients.
vs alternatives
Compared to vaginal estrogen tablets/creams/rings or DHEA inserts, ospemifene is systemic (though still SERM action) and does not require vaginal insertion. It offers a solution for the subgroup who simply won't use topical products.
Personal experience
They find them goopy, messy, junky, dirty, whatever... And they can take care of their vaginas with one pill a day. Turns out that adherence to that one pill a day is better than most of the other treatments, and the cost is on the lower end of all the treatments.
An oral SERM you mentioned it, ospemifene, which is a pill you take to make your vagina estrogenized... it's been documented to treat dryness unrelated to sex, unrelated to pain, dryness, what we call walking around dryness.

“Your eyes tear, your nose runs, your mouth drools, your vagina's supposed to be moist. That's the way to treat it, and not all of the treatments for pain are also approved for dryness.”— Highlights unique indication advantage.
Dr. Simon details how DHEA (prasterone) vaginal inserts are converted within the vaginal tissue into both estrogen and testosterone, with specific benefits for the vestibule, making it a unique therapy for GSM with dyspareunia.
He was part of the development work with Dr. Fernand Labrie. The DHEA insert size was designed to allow a small amount of leakage to the vestibule, providing both emollient properties and local testosterone to androgen-responsive tissue (embryonic male remnant). This dual estrogen-androgen effect addresses tissue health beyond what estrogen alone provides, particularly for the vaginal opening. He implies this may be why some women respond better to DHEA than estrogen-only products.
vs alternatives
Unlike local estrogen, DHEA adds a local testosterone effect on the vestibule. Compared to ospemifene, it is a local insert rather than systemic pill.
DHEA stands for dehydroepiandrosterone... It's an adrenal adrenal hormone that is converted, in this case converted from those vaginal inserts, in the vaginal tissue to both estrogen and testosterone. And it has added effects on the testosterone responsive elements of the vagina and vulva, which are unique and really quite important.
Also said
“The size of those DHEA inserts were determined to have a little leakage, a little leakage, to the vestibule to act both because of the emollient properties of the product itself, and also from the testosterone on the vestibule.”— Explains the intentional design feature for dual action.
Hyaluronic acid vaginal moisturizers and lubricants
Product
When the host mentions women using hyaluronic acid products for chafing and dryness, Dr. Simon agrees that for some women, OTC moisturizers and lubricants are sufficient—until they start getting recurrent UTIs or it's not enough.
Dr. Simon does not name a specific brand but endorses the use of hyaluronic acid-based moisturizers (separate from lubricants) as an acceptable first-line for mild vaginal dryness, especially for women who are fearful of the black box warning on estrogens. He says he agrees with this approach until infection or significant atrophy proves it inadequate, at which point he moves to prescription hormones to prevent tissue loss.
vs alternatives
These are non-prescription and avoid the black-box warning, making them psychologically acceptable for some women. However, they do not reverse atrophy like estrogen or DHEA, so they are for symptom management, not tissue restoration.
There are hyaluronic acid products, there are moisturizers separate from lubricants, and for some women that's all they need or all they want or all they feel like they can use cuz they're still afraid of the box warning. I can agree with that until they have urinary tract infections or until it's not good enough.

You can't eat the same thing every meal and still enjoy it the same as the first time you taste that delicious morsel... So what happens to couples is they develop a sexual script... It's boring. It becomes even more boring. It becomes eating at the same restaurant every single day. Got to change it up.
A vivid and relatable analogy for why long-term sex loses its appeal and how novelty is the fix.
Intercourse, penis and vagina intercourse, with a person who has a non-erect, weak-erect penis is actually worse for him than it is in terms of the sexual encounter because she or they can end up with a broken penis.
