KOMPAS.com - Impact of overweight or obesity on the health experts continue to be studied. Recent studies have revealed that obese men have worse sperm quality than men whose weight is balanced.
For decades experts examine the impact of obesity on fertility of a man. Some literature mentions, sperm quality lower fat man, seen from low sperm counts and sperm are able to swim swiftly.
New study conducted by researchers from Argentina reinforce previous studies. The researchers evaluated 794 semen samples with a partner a man who is conducting a program of pregnancy.
The researchers found that 155 men classified as obese have a bit of sperm that can swim with the agile and able to migrate compared with men whose weight is normal.
Obese men also tend to have levels of neutral alpha-glucosidase (NAG), an enzyme that is released by the epididymal fluid, which indicates whether a mature sperm cell and can swim. NAG levels in seminal fluid could be a sign of good or poor function of the epididymis.
"This is the first study that reveals the impact of obesity on epididymal function. Even so, it does not mean a man will be infertile due to weight gain," said Dr. Ana Carolina Martini from the National University of Cordoba, Argentina.
Although the effect on the least number of active sperm swim, in research conducted by Dr. Ana is not found the impact of obesity on semen quality, including sperm count, testosterone levels, and the number of sperm with normal shape.
However, Dr. Ana reveals, there is still a chance for obese men to improve sperm quality by reducing the weight of his body. Research has shown that weight reduction could restore reproductive hormone balance.
This study, explains Dr. Ana, has some limitations, namely the respondent is a person who does have fertility problems and levels of actual body mass index can not be a measure of how much actual body fat. Experts say, the measurement of abdominal fat is more effective to know the sex hormone levels compared with body mass index.
