Prostate cancer is the most common tumor in men. The American Cancer Society projects 220,800 men will be diagnosed with the disease in 2015. The cancer typically turns deadly after tumors stop responding to drugs that block production of testosterone and its receptors, an approach called androgen deprivation therapy that has been standard for 70 years. This is really the most lethal form of prostate cancer, said Michael Schweizer, the … Read more »

Reading Time: < 1 minute Their testosterone levels were measured from saliva samples and they were presented with a plate of mashed potatoes and invited to add chili sauce to taste. Those who added the most hot sauce had the highest testosterone. The hormone drives men to seek thrills and new sensations, leading them to frequent "more stimulating social groups and take more risks," according to Professor Begue.

Simultaneously, that's when our faces went from looking like the skull on the left, to the one on the right. A group of researchers from Duke and the University of Utah are theorizing that the correlation is not coincidence - that, in fact, the changing shape of skulls signals a change in something else that would have made cooperation more likely: A drop in male testosterone levels. "Looking mostly at the brow ridges, the area above your eyes... and the shape of … Read more »

Prior studies found that the administration of a single dose of testosterone influenced brain circuit function. Surprisingly, however, these studies were conducted exclusively in women. Researchers, led by Dr. Justin Carr, sought to rectify this gap by conducting a study of the effects of testosterone on the brain's response to threat cues in healthy men. They focused … Read more »
