Men who were overweight or obese, as their female counterparts, have a lower chance to become parents, based on the comparison of sperm quality are presented in meetings on fertility in Europe on Monday (4 / 7).
In what is described as the largest study of it, the doctors examined the sperm samples from 1940 men and match them with donor weight.
Benchmarks, measuring the body mass index (BMI), a measure of body fat among adults. Based on that, a normal body weight defined as BMI 18.5 to 25; 25-30 overweight and obesity as 30 or more.
The higher the count on excessive weight, the worse the quality of sperm, especially among those in the overweight category, according to the findings, presented at the annual conference of the European Society of Human Reproduction and Embryology (ESHRE) in Stockholm, Sweden.
"Excess weight resulting in changes in sperm characteristics, possibly due to hormone disruption, resulting in sperm count, vitality motalitas and fewer," said Paul Cohen-Bacrie, Director of Science at Eylau-Unilabs in Paris, part of a network of laboratories in 12 countries Europe, based in Switzerland.
"This resulted in the loss of potential fertilization," says Cohen-Bacrie by telephone.
That study found fewer sperm counts to 10 percent among men who were overweight, and up to 20 percent among men who are overweight, compared with their counterparts with normal weight.
Percentage of men who have zero sperm count increased almost fourfold, from one percent in the normal weight category, so 3.8 percent, the category of men who are overweight.
