The vagina is traditionally thought of as a passive organ in the female reproductive system, serving primarily as a passageway for menstrual blood, sexual intercourse and childbirth. However, recent research has shed light on the vagina's role as an endocrine organ that plays a crucial role in female hormonal balance and overall health. Particularly, growing evidence shows that the human vagina can be considered both as source and target of androgens, in view of the novel concept of 'intracrinology'. Besides the well-known role of estrogens, androgens are also crucial for the development and maintenance of healthy genitourinary tissues in women. As androgen levels decline with age, and estrogen levels fall during the menopausal transition, the tissues in the vagina, together with those in the urinary tract, become thinner, drier and less elastic, leading to a variety of uncomfortable and sometimes painful symptoms, clustered in the genitourinary syndrome of menopause (GSM). Given the lack of testosterone-based or androstenedione-based products approved by regulatory agencies to treat GSM, the possibility of using intravaginal prasterone, which works by providing a local source of dehydroepiandrosterone (DHEA) to the vaginal tissues, appears to be a targeted treatment. Further studies are needed to better assess its safety and efficacy.
