Men with obesity can double their sperm count

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, 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.

“It was surprising to us that such a big improvement can be shown in the semen quality in connection with a weight loss. And as 18 percent of Danes have obesity, this new knowledge may actually make a difference,” says Professor Signe Torekov who headed the study together with Professor Romain Barres at the Novo Nordisk Foundation Center for Basic Metabolic Research.

The new findings may be good news for the fertility, as a link between higher sperm count and faster achievement of pregnancy has previously been shown.

The study has been published in the recognised journal Human Reproduction which enjoys one of the highest rankings in the field of fertility. A total of 56 men with obesity participated, aged 18-65 years and with a body mass index between 32 and 43.
