Males all around the world are affected by deteriorating semen high quality—sometimes called an outright fertility disaster.

In a brand new medical research, researchers from the College of Copenhagen and Hvidovre Hospital present that males with weight problems enhance their semen high quality in the event that they shed weight—and keep the burden loss.
“It was shocking to us that such an enormous enchancment might be proven within the semen high quality in reference to a weight reduction. And as 18 % of Danes have weight problems, this new data may very well make a distinction,” says Professor Signe Torekov who headed the research along with Professor Romain Barres on the Novo Nordisk Basis Heart for Primary Metabolic Analysis.
The brand new findings could also be excellent news for the fertility subject, as a hyperlink between increased sperm depend and sooner achievement of being pregnant has beforehand been proven.
The research has been printed within the journal Human Replica. A complete of 56 males with weight problems participated, aged 18-65 years and with a physique mass index between 32 and 43.
Sustained weight reduction mandatory
Signe Torekov explains that it has lengthy been identified that weight problems is related to diminished semen high quality. Earlier research have additionally instructed a hyperlink between weight reduction and elevated semen high quality, however these research have had so few individuals or such modest weight reduction that it has been troublesome to attract conclusions from them, she explains.
“However now we’re able to do exactly that. That is the primary long-term randomized research, the place we’ve proven that semen high quality in males with weight problems enhance with a sustained weight reduction,” says Signe Torekov on the Division of Biomedical Sciences.
“The boys misplaced a mean of 16.5 kg, which elevated the sperm focus by 50 % and the sperm depend by 40 % eight weeks because the weight reduction. Throughout the 52 weeks, the trial lasted following the burden loss, the lads maintained the improved semen high quality. However solely the lads who maintained the burden loss: after a yr, these males had twice as many sperm cells as earlier than their weight reduction. The boys who regained weight, misplaced the enhancements in semen high quality,” she explains.
Half of a bigger research
The research is a sub research of a significant publication on weight reduction, which was printed within the New England Journal of Drugs in Could 2021. A complete of 215 Danes with weight problems participated within the bigger research. It was amongst these individuals that 56 of the lads additionally supplied semen samples to research whether or not semen high quality and weight reduction may very well be associated.
Within the trial, all individuals first adopted an eight-week routine with a low-calorie food plan, leading to a weight reduction. Then the individuals have been randomly divided into 4 teams.
Two of the teams obtained placebo medicine, whereas the opposite two teams obtained weight problems medicine. Among the many two placebo teams, one group needed to comply with an train program the place every week, they needed to do a minimal of 150 minutes of average bodily coaching or 75 minutes of laborious coaching—or a mix.
The opposite group didn’t change their standard degree of bodily exercise. The 2 teams that obtained weight problems medicine have been divided in the identical manner, into a gaggle with and a gaggle with out an train program.
After a yr, it was proven that the group that solely exercised and didn’t obtain medicine, in addition to the group that solely obtained weight problems medicine and didn’t train, maintained the burden lack of 13 kg. The group that each obtained weight problems medicine and exercised misplaced extra weight and improved well being. The placebo group—those that thought they got medicine, however didn’t train—had regained half of the burden loss with aggravation of most of the threat components associated to improvement of kind 2 diabetes and heart problems.
