The man sex hormone

Testosterone, commonly reflection of as the man sex hormone, seems to promote integrity, a new study suggests. Testosterone also is certainly establish in women but at reduce levels than in men, and is typically associated with masculine attributes such as aggressiveness and risky behavior. However, recent research indicates that the hormone also encourages social behavior. Testosterone supplements are touted as a remedy for low libido, but men who take them may reduce their odds of fathering a child, new research suggests.
Many men who sought infertility treatment at two U.S. clinics reported taking prescription testosterone supplements, according to a new study. And in most cases their sperm counts skyrocketed after they stopped taking the male hormone. The study, restricted to a pair of clinics in Alabama and Kansas, looked at the years 2005 to 2011. The researchers don’t know if testosterone supplements, which continue to benefit favour, are contributing to even more cases of infertility now. Nor is it unclouded whether the hormone is harming fertility across the nation. Still, the investigation suggests that testosterone spells discomfit for many American men who want to have children, said study co-creator Dr. Peter Kolettis, a professor of urology at the University of Alabama at Birmingham. “This has become a preventable cause of infertility.” Use of testosterone supplements — or “T” — is quickly rising in the United States, and some observers think use will stay behind inflated as more men see it as a possible cure for fatigue and flagging sex motivate. Critics, however, question whether testosterone treatment is being prescribed to men who don’t need it. The results challenge the belief that testosterone effects are limited to promoting antisocial behavior, the study authors said. They believe, instead, that testosterone may increase pride and the need to develop a positive self-image.
