Female libido is a complex interplay of hormones, brain chemistry, physical health, and psychological factors. When women are told their low libido is "just normal with age" or "just stress," they are often being dismissed rather than properly evaluated.
The most important and frequently overlooked cause is testosterone deficiency. Women produce testosterone in their ovaries and adrenal glands — it is as critical for female libido as it is for male. After 40, and dramatically after menopause, testosterone declines significantly. Restoring it to optimal levels is transformative for many women.
A landmark study in the New England Journal of Medicine found that testosterone therapy in postmenopausal women produced significant improvements in sexual desire, arousal, orgasm frequency, and pleasure — with a clean safety profile. Testosterone is dramatically underutilized in women's sexual health care.
Beyond testosterone, we assess estrogen (affects vaginal health and receptivity), thyroid (low thyroid suppresses libido and energy), medications (SSRIs, hormonal birth control, and blood pressure medications commonly suppress libido), and the neurological desire pathway — where PT-141 can produce dramatic results independent of hormone levels.
