Low Testosterone

Your mojo's missing, you're moody as a teen, your biceps have lost bulk. It could be low testosterone, or low T. While so-called male menopause (in which the male hormone takes a nosedive) affects a small percentage of men, virtually all males experience low T with age. Other causes range from illness and injury to stress and drinking. Learn how low testosterone affects health and how you can deal with it.

There's no cure for low testosterone, but when levels fall below 300 ng/dL and symptoms flow, testosterone replacement therapy can help bring back an AWOL mojo, improve concentration, increase muscle mass and more. The downsides? Usually a man will need therapy for life (getting injections every few weeks or using a testosterone patch or gel daily), and it does have risks.

When you're living the low T life, you may experience a range of side effects. If your testosterone levels dip enough to warrant hormone therapy and you want to give it a shot, it will likely help to alleviate many problems you may be experiencing. But there are other ways to deal with the ways low testosterone can drag you down.
