Surgery-related weight loss in men reverses testosterone deficiency, study finds

Summary:
Low testosterone levels and symptoms of male sexual dysfunction due to obesity may be reversible with weight loss after bariatric surgery, a new study finds.

Low testosterone levels and symptoms of male sexual dysfunction due to obesity may be reversible with weight loss after bariatric surgery, a new study finds.

The results were presented at The Endocrine Society's 93rd Annual Meeting in Boston.

"Morbidly obese men have a high prevalence of hypotestosteronenemia, or low testosterone, and of sexual dysfunction," said study co-author Jean-Paul Thissen, MD, PhD, a professor at the University of Louvain in Brussels. "It is reassuring that these problems are potentially curable by weight loss."

This study included 75 obese men who were patients at an obesity clinic between 2007 and 2010. The men had hormone testing, measurements of body fat and assessment by questionnaire of signs of androgen, or male hormone, deficiency. Signs assessed included erectile dysfunction and low sex drive. Among these patients, 17 underwent gastric bypass surgery and were reassessed three and 12 months later.

Initial assessment of the 75 patients showed that 54 had signs and symptoms of androgen deficiency, and 27 had low testosterone levels. The higher the men's body mass index, waist circumference and body fat, the lower their testosterone levels were. "This correlation suggests a potential causal relationship between obesity and low testosterone," Thissen said.

The 17 men who had weight-loss surgery lost an average of 90.2 pounds. One year after surgery, their testosterone levels increased significantly and were within the normal range, showing a reversal of testosterone deficiency, Thissen reported.

Low testosterone levels were not strongly associated with complaints of sexual dysfunction before surgery. However, Thissen said men did not complain of sexual dysfunction after surgery-related weight loss.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
