Sex hormone levels after menopause: androgens

SEX HORMONE LEVELS AFTER MENOPAUSE: ANDROGENS
ANDROSTENEDIONE This is the most constant androgen before and after menopause and is the main source of postmenopausal oestrogen. The level of androstenedione after menopause is about half that present during the early part of the menstrual cycle. It is a little lower in women who have had a surgical menopause. The ovaries produce androstenedione after menopause in response to high levels of LH. The adrenal glands also produce it both before and after menopause.
TESTOSTERONE The most powerful of the androgen hormones, testosterone influences hair growth, voice and libido in women. The level of testosterone after menopause tends to be a little less than it was during the early part of the menstrual cycle. The level after surgical menopause is about half that after natural menopause. The testosterone of postmenopausal women is produced by both the ovaries and the adrenal glands.
DEHYDRO EPIANDROSTERONE (DHA) This is produced by the adrenal glands before and after menopause, and its output falls to about a third through the menopause transition.
Inhibin
Inhibin is a recently discovered ovarian hormone with two major roles. It signals information to the brain about the state of egg production in the ovaries, and helps to regulate this process by controlling the level of FSH. After the menopause its level drops, which helps to explain why the level of FSH rises.
