Erectile Dysfunction? Try Losing Weight
Viagra gets the job done, but it's a quick fix. For many men, weaning themselves off the little blue pill and finding a longer-lasting solution to their sexual dysfunction may require hitting the gym and putting down the doughnuts. A new Australian study, published today in the Journal of Sexual Medicine, found that losing just 5% to 10% of body weight over a two-month period improved the erectile function and revved up the sex drive of obese men with diabetes. The findings are yet another reminder that obesity and erectile dysfunction (ED) often go hand in hand.

Male Pattern Balding May Be Due to Stem Cell Inactivation
Given the amount of angst over male pattern balding, surprisingly little is known about its cause at the cellular level. In a new study, published in the Journal of Clinical Investigation, a team led by George Cotsarelis, MD, chair of the Department of Dermatology at the University of Pennsylvania School of Medicine, has found that stem cells play an unexpected role in explaining what happens in bald scalp. Using cell samples from men undergoing hair transplants, the team compared follicles from bald scalp and non-bald scalp, and found that bald areas had the same number of stem cells as normal scalp in the same person.
