A woman whose testosterone is too low isn’t going to enjoy the same quality of life as a woman whose levels are optimal. The main predictor of low testosterone in women is a fading or nonexistent intimate life.Testosterone normally begins to decline as women approach middle age, though this can happen at any age due to other causes, like a stressful or traumatic event. In women, the ovaries produce most of the body’s testosterone. The adrenal glands also produce a small amount. During menopause, ovarian testosterone production sharply drops. Lower levels of testosterone can mean a decrease in energy and, even more noticeably, a decline in libido. Additionally, because free testosterone is no longer available for conversion into estradiol when needed, a decrease in testosterone production is actually a decrease in the body’s ability to regulate itself. Removal of the ovaries means an even more drastic drop in these hormones, so women who have undergone a hysterectomy may feel symptoms even more strongly and suddenly than naturally menopausal women.
