Men who have undergone bariatric surgery as a long-term way of losing weight might also benefit from increased testosterone levels post-surgery. However, there is no evidence that the sperm quality of a patient improves. These are the findings of a comprehensive review in the Springer journal Obesity Surgery, which is the official publication of the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO). The research was led by Shahzeer Karmali and was a collaborative effort between Yung Lee of McMaster University and Jerry Dang of the University of Alberta in Canada.
Hormonal changes, a drop in sexual functioning, and less satisfaction in bed are among the many downsides of obesity. Obese men in particular are known to experience lower testosterone levels, lower sexual satisfaction, and reduced fertility compared to men of normal weight. On average the odds of male infertility are said to increase by 10 per cent for every nine kilograms a man is overweight.
Up until now most studies on the relationship between fertility and bariatric surgery have been focused on women. So Lee and his colleagues set out to review the available research on the influence of this procedure on male sex hormones and sperm quality.
"As the prevalence of both male infertility and bariatric surgery increases, knowledge of how surgical intervention affects fertility outcomes may better inform patient and surgeon decisions on pursuing this procedure," says Lee.
