Use of ED Drugs With Recreational Drugs Can Be Dangerous
Some men who drink excessively or take recreational drugs such as methamphetamines, cocaine, or ecstasy find it difficult to get and maintain an erection and turn to erectile dysfunction (ED) medications for a temporary solution. While ED meds (Viagra, Levitra, and Cialis) are considered very safe on their own, doctors say mixing them with intoxicants could be unsafe, especially in large amounts. There could be risks associated, especially since many drugs lower blood pressure and impair judgment.

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.
