Loss of energy, libido and stamina are the symptoms that usually drive patients into the waiting rooms of anti-aging doctors. They're also the "classic" symptoms of declining hormone levels and the reason hormone-replacement therapy is the No. 1 weapon in the arsenal of prescription anti-aging medicine. Production of estrogen, progesterone and testosterone in women and testosterone in men decreases rapidly after age 35, says Nadu Tuakli, M.D., of the Anti-Aging and Longevity Institute in Baltimore.
Anti-aging physician Richard LeConde, who prescribes testosterone for his female patients, notes a dramatic improvement in their well being not seen with estrogen and progesterone alone. It definitely "produces an awakening in men," he says, but reports that most of the women for whom he adds testosterone "refuse to give it up."
