Testosterone - Women (5)

Testosterone in women - is it physiological and clinically important?

Testosterone is popularly known as the "male" hormone. While it is true that men have much higher levels of testosterone than women, and that testosterone contributes to secondary sex characteristics that physiologically distinguish men from women (increased muscle mass and facial/body hair), this does not mean that testosterone isn't important in women.

Testosterone Therapy vs. Estrogen Therapy in Surgically Menopausal Women - effectiveness comparison

In a previous article I outlined a study showing the effectiveness of testosterone therapy on menopausal symptoms in pre- and post-menopausal women. Here I will present and comment on an insightful study that compared head-to-head the effectiveness of testosterone therapy and estrogen therapy in surgically menopausal women who had their ovaries removed.[1]
 
STUDY DESIGN:
Before the surgical removal of both ovaries (bilateral ovariectomy) women were randomly assigned to either a testosterone alone, estrogen alone, or placebo groups. There were 10 patients in each group.
 
Mean age of the women was 46 years. They had underwent bilateral ovariectomy due to having uterine fibroids (aka myoma), which are non-cancerous (benign) tumors that develop in the womb (uterus).
 
HORMONE TREATMENTS:
 
The testosterone group received injectable testosterone (enanthate); 200 mg/ml.
 
The estrogen group received injectable estradiol; 10mg/ml.
 
The testosterone/estrogen group received injectable testosterone (enanthate) 150 mg + 8.5 mg estradiol/ml.
 
All groups received 1 ml intramuscular injections every 28 days for 3 months.

Beneficial effects of testosterone therapy on menopause symptoms and quality of life

Testosterone levels in women decline steeply with age during the reproductive years; by the time women reach their late 40, their blood testosterone levels are approximately half what they were in their 20s.[1, 2]

Low testosterone levels predict all-cause mortality and cardiovascular events in women

A study in a large primary care patient population shows that low baseline testosterone in women aged 43-72 years is associated with increased all-cause mortality and cardiovascular events. This association was found to be largely independent of traditional risk factors, and supports the notion that the hormonal status in middle age and older women might impact morality outcomes.

The objective of the study was to determine whether baseline testosterone levels in women are associated with future overall or cardiovascular morbidity and mortality.
