A small study revealed a decrease in the number of sperm and its concentration of males in high-fat diets.
Can fatty foods consumed by men damage their fertility? NEW YORK (Reuters Health) – Eating high-fat foods reduces sperm levels in men, according to a new study.
The study was small and included only 99 American men divided into three groups based on their total fat intake.
The study, published online March 14 in the journal Human Reproduction, found that those with the highest daily fat intake had a total sperm count lower than 43 percent and a sperm concentration lower than 38 percent. that those who had the least amount of fat
“Although this study is limited to the number of patients evaluated, I think it tells us something important because it reminds us that men’s fertility is sensitive and can be easily affected by the same things that affect our overall health,” said Dr. Joseph Alokal, Director of Reproductive Health at the School of Medicine at the University of New York and assistant professor at the School of Medicine at the University of New York in New York City.
“This is another good guide that reminds us that simple health interventions such as diet and exercise can be helpful in improving sperm count and having a baby,” said Walkal, who was not part of the new study.
The total number of sperm refers to the total number of sperm in the ejaculate, while the sperm concentration is the number of sperm in a certain amount of semen.
The World Health Organization defines the total number of sperm as at least 39 million sperm in the sperm and the normal sperm concentration of at least 15 million sperm per milliliter of semen.
Saturated fat seems to be the main factor associated with semen quality in the study. The researchers found that men who consumed the most saturated fat had a 35 percent lower sperm count and a 38 percent lower sperm count than those who ate less saturated fat.
The study’s author, Gil Ataman, agreed that the results confirm the importance of a healthy diet. “The size of the partnership is very exciting and provides more support for health efforts to reduce the consumption of saturated fats in relation to other health outcomes such as cardiovascular disease,” he said in a press release.
The study also found that men who consumed omega-3 fatty acids (the type found in some fish oils) had about 2 percent of the sperm that formed properly from those who ate less omega-3.
The researchers observed that 71 percent of the men in the study were overweight or obese, almost 74 percent of the men in the general population of the United States.
He stressed that more research is needed to confirm the results of this small study. “Certainly, more work like this, which analyzes the increase in the number of patients over a longer period of time, would be very useful,” he said. The study is also intrinsically observable and can not prove cause and effect.
Ataman was a clinical and research researcher in reproductive endocrinology and infertility at Massachusetts General Hospital and received training in obstetrics, gynecology and reproductive biology at Harvard Medical School when she conducted the research. She is currently an associate professor of obstetrics and gynecology at Dartmouth Medical College and a specialist in subspecialties in endocrinology and reproduction at Dartmouth-Hitchcock Medical Center.
