Men who maintain weight loss can double their sperm count: study

Men all over the world are suffering from deteriorating semen quality — often referred to as an outright fertility crisis. Now, however, there may be good news for some of the men who are experiencing problems.

In a new clinical study, published in Human Reproduction, researchers from the University of Copenhagen and Hvidovre Hospital show that men with obesity improve their semen quality if they lose weight and maintain the weight loss.

According to professor Signe Torekov, who headed the study together with Professor Romain Barres at the Novo Nordisk Foundation Center for Basic Metabolic Research, “The men lost an average of 16.5 kg [about 36 pounds], which increased the sperm concentration by 50 percent and the sperm count by 40 percent eight weeks since the weight loss.”

But only the men who maintained the weight loss the 52 weeks the trial lasted maintained the improved semen quality. “After a year, these men had twice as many sperm cells as before their weight loss. The men who regained weight lost the improvements in semen quality. It was surprising to us that such a big improvement can be shown in the semen quality in connection with a weight loss,” she says.
