Globally, there is a deterioration in the quality of semen in men, which is associated with reproductive disorders and infertility. Obesity in men is considered one of the potential causes of infertility. A new study from the University of Copenhagen and Hvidovre Hospital has shown that obese men can improve their semen quality if they lose weight and maintain a healthy weight. Weight loss improves semen quality The study, based on a May 2021 publication in the New England Journal of Medicine, was conducted on 215 obese men. Of these 215 men, researchers selected 56 who participated in a parallel study. All 215 participants followed a low-calorie diet for 8 weeks, which resulted in a loss of body weight. Then the participants were divided into 4 groups. Two of the groups received a placebo and the other two received an anti-obesity drug. In the 2 subgroups, only one had to follow a special exercise program. After a year of follow-up, participants in the placebo group who exercised, as well as those in the group who only took anti-obesity drugs and did not exercise, were able to maintain the 13 kg of body weight they had already lost. The group that took medication and followed an exercise program lost even more body weight and improved their overall health. Half of the participants in the placebo and non-exercise group maintained the weight loss and had an increased risk of developing type 2 diabetes and cardiovascular disease. The researchers then examined seminal fluid samples from 56 of the obese participants (BMI = 32 to 43), ages 18 to 65. The aim was to investigate the relationship between semen quality and weight loss. Scientists have found that weight loss has a real positive impact on semen quality. Men who had lost an average of 16.5 kg of body weight had a 50% increase in sperm concentration and a 40% increase in sperm count within 8 weeks of weight loss. Losing body weight can lead to a significant improvement in semen quality. Permanent weight loss Improvement in semen quality is seen when body weight loss is permanent and sustainable in the long term. For 52 weeks after weight loss, an improvement in semen quality was observed. After one year, the participants who successfully maintained the weight loss had twice the amount of sperm than before the weight loss, the scientists explained. Men who have regained weightfor those who lost the improvement in semen quality. The link between a higher sperm count and a greater chance of pregnancy has already been proven, underscoring the importance of body weight control in dealing with reproductive problems.
