Sexual desire in women is fuelled by a number of hormones. The two major hormones that affect a woman’s sexual desire and functioning are estrogen and testosterone.
This hormone enables sexual and reproductive development in women. Responsible for keeping your vulva and vagina moist and healthy, a lack of estrogen can leave genital tissues dry and less acidic, thus making you vulnerable to infections. Estrogen loss can also lead to lubrication problems which cause dryness and pain during intercourse. Over time, low estrogen levels produce significant changes in the entire urinary and genital area, including reduced blood flow to the vagina.
Though testosterone is mainly a male hormone, all women produce it in a small quantity in the ovaries and adrenal glands. Testosterone levels do not decline suddenly at menopause, but start to fall in the mid -20s. This hormone plays a crucial role in increasing a woman's sex drive or libido. More specifically, testosterone in women contributes to greater sensitivity and arousal of the nipples, clitoris and labia. This in turn enhances the sexual mood and experience of a woman.
