Menopause, skin and common dermatosis. Part 3: genital disorders.

Oestrogen plays a vital role in maintaining a normal vulvovaginal epithelium, vaginal lubrication, as well as a healthy microbiome to ensure an acidic pH. The decrease in oestrogen levels in women going through menopause results in both physiological and physical changes of the genitourinary system, and more specifically the vulva. We conducted a literature review on the effects of low oestrogen levels on the physiology and function of the vulva and the vulvovaginal epithelium. 'Genitourinary syndrome of menopause' (GSM) is the term used to describe the signs and symptoms of a low oestrogen state. The symptoms and signs of GSM can overlap or coexist with other vulval dermatoses. Expert opinion is needed to diagnose and manage vulval dermatoses in menopause. This article will discuss the signs and symptoms of GSM, as well as the different management options available. Other vulval dermatoses that can be affected by hypo-oestrogenism are also reviewed.
