So-Called Male Menopause Not Common

Only about 2% of men over 40 develop symptoms related to low testosterone levels, a new study finds. This condition is called late-onset hypogonadism. Some people refer to it as “male menopause.” But there has been debate about whether male menopause even exists. This study is the first to link concrete symptoms with testosterone levels. The authors concluded that the syndrome is less common than people had thought. Researchers measured testosterone levels in 3,369 men, aged 40 to 79. They also asked them about symptoms. Three sexual symptoms were most likely to be linked to low testosterone. The symptoms were a reduction in morning erections, lower sex drive and impotence (erectile dysfunction). The authors said men should have all three of these symptoms and low testosterone to be diagnosed with late-onset hypogonadism. It is treated with hormone supplements.
