Testosterone deficiency not the only cause of age-associated changes in men

A study by MGH researchers finds that some of the symptoms often seen in middle-aged men – changes in body composition, energy, strength and sexual function – are caused not only by decreases in testosterone production but also by reduced levels of estrogen.
