Obesity harms fertility according to the results of a new scientific study carried out by researchers at the Stanford University School of Medicine in California in the United States.
Scientists conducted a medical survey of 468 couples who intended to conceive and tested several aspects of men’s sperm.
They measured the men’s height, weight, BMI and scanned their sperm.
Men who are not very sensitive to prevention messages
According to Dr. Keith Jarvi, urologist, a “normal” ejaculation contains between 2 and 5ml of semen. And, men who produce less than 1.5ml of semen are very often infertile.
In their study, the researchers found that men with normal BMIs produced 3.3 ml of semen per ejaculation, and overweight or obese men only 2.8 ml.
Based on the results of their research, Dr. Keith Jarvi and his team concluded that “the heavier a man, the more likely he is to have a low sperm count and impair his fertility. Unfortunately, we have also noticed that men seem insensitive to these prevention messages and are not ready to take charge. Indeed the only question that overweight men ask is whether the phenomenon is reversible. They don’t want to lose weight if they are unsure of the outcome. But scientists don’t seem to be able to know whether weight loss will necessarily mean improved sperm scanning.
These new scientific claims confirm the findings of an Australian study from the University of Melbourne which found that “sperm from obese males may delay fetal development and reduce the embryo’s chances of successfully implanting.” “
“However, many men do not understand the importance of their role, but it is important that they are in good health before conceiving”, explained the researcher in charge of the study, David Gardner. up to creating life “.
