Hormonal changes and diminished sexual quality of life among obese men are correlation to the degree of obesity, and both are improved after gastric bypass surgery as per a newly released study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

"Prior studies have observed that obesity is corcorrelation to lower sperm count and can be linked to infertility, but we wanted to know if obesity was biologically linked to an unsatisfying sex life, and if so, could it be reversible," said Dr. Ahmad Hammoud, MD, of the University of Utah and main author of the study. "Our results show that the answer to both questions appears to be yes".

For this study, scientists followed 64 men over two years who participated in the Utah Obesity Study, which investigated the two-year morbidity of severely obese men undergoing Roux-en-Y gastric bypass surgery in comparison to controls. Scientists measured weight, BMI (body mass index) and reproductive hormone levels of participants at the beginning of the study and once more two years later. Similarly subjects completed a questionnaire designed to assess the impact of weight on quality of life in obese individuals at the onset of the study and again two years later.

"In our study population, we observed that lower testosterone levels and diminished ratings for sexual quality of life were correlated with increased BMI," said Dr. Hammoud. "Subjects who lost weight through bariatric surgery experienced a reduction in estradiol levels, an increase in testosterone levels and an increase in ratings of sexual quality of life".

Dr. Hammoud points out that results from this study highlight an association between sexual quality of life and hormonal measures independent from weight. Because this relationship is confounded by biopsychosocial aspects of obesity, further studies are mandatory to determine a cause and effect relationship.
