Female Testosterone   is an important topic to understand.

In May, the International Menopause Society is holding their annual World Menopause Congress in Cancun, Mexico. Dr. Karen Miller will be speaking about female testosterone with  the topic ” androgen physiology in women- back to basics”. Dr. Miller is an endocrinologist , a professor at Harvard Medical School and an advocate for testosterone therapy in females.

Dr. Miller will touch on many of these key points we present to you in this blog.

Women provide a far more complex sex-hormone picture than men, with three hormones contributing to the overall makeup of their hormonal balance.

Women produce estrogen, progesterone and testosterone. The ovaries produce the bulk of estrogen during the years leading up to menopause and substantially less post-menopause.

During the menstrual years, progesterone is produced once ovulation has taken place. Progesterone ceases to be produced when ovulation stops at menopause. In some females, progesterone production stops even before menstruation ceases.

Female testosterone  is produced by the ovaries and adrenal glands on a continual basis. Testosterone blood levels are at their highest around age 20 and decline steadily with time. At the age of 40 a woman’s serum testosterone levels are approximately half what they were at age 20. This level continues to fall with age.

Testosterone is vital in the preservation of bone, for its positive effect on libido and for maintenance of energy levels. It also has a role in the growth of normal body hair.

Testosterone secretion follows a diurnal rhythm in females. This means it rises and falls over a 24 hour period. Testosterone production occurs during the night and early morning with levels highest on waking. Serum testosterone levels slowly decrease during the day and are lowest in the late afternoon and early evening.
