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.
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).
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.
