Gastric Bypass Surgery May Improve Sex Life in Obese Men
Surgery is associated with increased production of reproductive hormones and sexual function
THURSDAY, Mar. 5 (HealthDay News) -- In obese men, Roux-en-Y gastric bypass surgery may be associated with increased production of reproductive hormones and improved sexual function, according to study findings released online Jan. 27 in advance of publication in the Journal of Clinical Endocrinology & Metabolism.
Ahmad Hammoud, M.D., of the University of Utah in Salt Lake City, and colleagues studied 64 severely obese men, including 22 who had gastric bypass surgery and 42 controls.
The researchers found that increasing obesity was positively associated with estradiol and negatively associated with total and free testosterone. After two years, they found that the men in the gastric bypass surgery group experienced mean losses of 16.6 kg/m2 in BMI and 8.1 pg/mL in estradiol, and mean increases of 310.8 ng/dL and 45.2 pg/mL in total and free testosterone, respectively.
"Weight loss after surgery was also associated with an improvement in all four aspects of sexual quality of life," the authors write. "Non-surgical control subjects did not exhibit significant changes in anthropomorphic, hormonal, or sexual quality of life measures."
