TDSM will study the physiology of testosterone in women ages 21-60 who have had surgical menopause (uterus and both ovaries removed). Testosterone is commonly thought of as a "male hormone" thus being that it is the male's primary hormone. Women produce testosterone in much smaller amounts and despite this, testosterone still plays a significant role. Fifty percent of a women's testosterone is made in her adrenal glands (glands that sit on top of the kidneys) and fifty percent is made in her ovaries. When a woman has her ovaries removed it is thought that her testosterone levels decrease rapidly and significantly. This study will be examining testosterone's role in sexual function, general well being, muscle performance, cognitive function, carbohydrate metabolism and muscle and fat distribution.
