Testosterone, Viagra not a winning combination for erectile dysfunction


Posted by Dr. Michael White, Updated on December 27th, 2017

Reading Time: 2 minutesUsing a testosterone gel in addition to Viagra doesn't make the little blue pill work any better, according to a new study. The report's lead researcher said testosterone is typically prescribed to men who have both low testosterone levels and symptoms such as little interest in sex or low bone and muscle mass. But, "there's a tremendous amount of clinical judgment" that goes into that, said Dr. Matthew Spitzer, from the Boston University School of Medicine. "People are certainly being prescribed and using these medications at increasing amounts." According to Spitzer, studies have suggested that about one-quarter to one-third of … Read more »

(UPI/Ezio Petersen) License photo STANFORD, Calif., April 30 (UPI) -- Men higher in testosterone are more easily threatened and as a result they overcompensate when their masculinity is threatened, U.S. researchers say. Robb Willer, an associate professor of sociology at Stanford University, and colleagues enlisted 54 undergraduate men at the University of Iowa who took a gender identity survey about their assertiveness or other qualities typically associated with masculinity or femininity. They were then given feedback the men believed was based on the survey but … Read more »

Posted by Dr. Michael White, Updated on December 27th, 2017

Reading Time: 3 minutesAug. 13, 2013 The everyday physical activities of an isolated group of forager-farmers in central Bolivia are providing valuable information about how industrialization and its associated modern amenities may impact health and wellness. Studying short-term spikes in the testosterone levels of Tsimane men, UC Santa Barbara anthropologists Ben Trumble and Michael Gurven have found that the act of chopping down trees -- a physically demanding task that is critical to successful farming and food production -- results in greater increases in testosterone than does a directly competitive activity such as soccer.

Competition-linked bursts of testosterone are fundamental aspect of human biology, study of Amazonian tribe suggests


Posted by Dr. Michael White, Updated on December 25th, 2017

Reading Time: 2 minutesScienceDaily (Mar. 27, 2012) It's a rough life for the Tsimane, an isolated indigenous group in Bolivia. They make a living by hunting and foraging in forests, fishing in streams and clearing land by hand to grow crops. Their rugged lifestyle might imply that Tsimane men have elevated testosterone to maintain the physical activity required to survive each day. But new research shows that Tsimane ("chi-MAH-nay") men have a third less baseline testosterone compared with men living in the United States, where life is less physically demanding. And unlike men in the U.S., the Bolivian foragers-farmers do not show declines … Read more »

Testosterone Boosters Unnecessary?


Posted by Dr. Michael White, Updated on December 24th, 2017

Reading Time: 2 minutesLow testosterone, or hypogonadism, is a legitimate health problem. Men who have it can suffer a variety of conditions, from low energy and sex drive to depression, weight gain and even bone loss. But chances are, you dont have this problem, and neither do many of the men you know. The best evidence is that only about 2 percent of the U.S. male population ages 40 to 79 are below the minimum T threshold. That hasnt prevented a wave of interest in testosterone-replacement therapy. At the top of the hierarchy, there are the prescription-only gels and injections that replace the … Read more »

Previous research showed men typically experience more severe viral and other microbial infections than women, who tend to mount stronger immune responses to infections and vaccinations.

Antibodies, Not Hard Bodies: The Real Reason Women Drool Over Brad Pitt

Reading Time: 2 minutesWomen may drool over George Clooney and Brad Pitt, but their lust may be more for these macho guys' immune systems than their pretty faces and chiseled abs, new research suggests.

The findings suggest that women may be attracted to manly facial types because the macho look signals good health.

Reading Time: 2 minutesWashington, October 11 (ANI): Testosterone is considered the male hormone, standing for aggression and posturing, but researchers from the University of Bonn have now revealed that this sex hormone surprisingly also fosters social behaviour.
