Soy Health Benefits - Men's Health
In this video, Mark Messina, PhD, MS, Adjunct Associate Professor in the Department of Nutrition, School of Public Health, at Loma Linda University, discusses soy and men’s health. Most importantly, there is no evidence from the extensive amount of clinical research conducted that soybean isoflavones feminize men. An analysis of more than 30 clinical studies showed that neither soyfoods nor soy extracts lowered testosterone levels. In addition, nine studies have shown that soy doesn’t increase estrogen levels. The evidence also shows that soy doesn’t adversely affect sperm or semen. In fact, there is a case report describing an infertile man with low sperm concentration whose sperm concentration actually increased in response to taking isoflavones for three months.
