What DHEA Has to Do With Your Sex Life After Menopause
DHEA (dehydroepiandrosterone) is a hormone produced by the adrenal glands that serves as a precursor to both estrogen and testosterone. As the “mother hormone” for sex steroids, its decline with age — and particularly at menopause — has downstream effects on estrogen and testosterone levels throughout the body, including in genital tissue.
In 2016, the FDA approved an intravaginal DHEA preparation (prasterone/Intrarosa) specifically for the treatment of painful intercourse due to GSM — making it one of the few FDA-approved options for this condition. Understanding DHEA’s role helps women evaluate all available treatment options.
How DHEA Works in Female Sexual Health
When applied vaginally, DHEA is converted locally into both estrogen and testosterone through enzymes naturally present in vaginal tissue. This creates a localized hormonal environment that:
- Restores vaginal tissue thickness and elasticity
- Improves natural lubrication
- Reduces vaginal pH toward its healthy acidic range
- Supports nerve sensitivity and arousal through the testosterone conversion
- Reduces pain during intercourse
The dual conversion is significant: unlike purely estrogenic vaginal treatments, DHEA also provides the testosterone component locally — potentially offering a broader benefit for sexual response beyond tissue restoration alone.
The Evidence for Prasterone (Intrarosa)
The FDA approval was supported by clinical trials showing that intravaginal prasterone:
- Significantly reduced the severity of painful intercourse
- Improved vaginal tissue parameters (cell maturity, pH, moisture)
- Improved sexual desire and arousal (secondary endpoints)
Importantly, systemic DHEA and estrogen levels remain within normal postmenopausal ranges during use, supporting its safety profile.
Oral DHEA Supplements
Over-the-counter oral DHEA supplements are widely available. The evidence for these in improving sexual function is much weaker than for intravaginal prasterone. Oral DHEA raises systemic DHEA levels but conversion to active sex steroids is variable and unpredictable, and the effect on vaginal tissue specifically is minimal. They’re not an equivalent substitute for prescription intravaginal treatment.
Where DHEA Fits in a Treatment Plan
Intravaginal DHEA (Intrarosa) is a strong option for women seeking treatment for GSM and painful sex who prefer a single product that provides both estrogenic and androgenic effects locally. It can be used alongside prescription topical arousal treatments like
Climax RX — the DHEA preparation addresses the ongoing tissue health, while Climax RX provides the pre-intimacy arousal support.
FAQ
Is intravaginal DHEA (prasterone) safe?
Clinical trials supporting the FDA approval found intravaginal prasterone to be well-tolerated, with minimal systemic hormone elevation. It’s considered safe for most women, with an ongoing safety profile similar to topical vaginal estrogen.Can oral DHEA supplements replace prescription prasterone?
No. The vaginal delivery route of prescription prasterone achieves local tissue effects that oral supplementation doesn’t replicate reliably. If vaginal symptoms are the target, prescription intravaginal treatment is the appropriate approach.Does DHEA improve libido as well as vaginal symptoms?
Studies show improvements in sexual desire and arousal with intravaginal DHEA, likely through the testosterone conversion. These effects are secondary benefits to the primary tissue restoration effect, and may be more modest than with systemic testosterone therapy targeted specifically for desire.
