Fish oil supplements tied to improved male fertility-Reuters
In Denmark, where there is a conscription system, Danish men aged 18 years and older are given medical examinations to determine whether they are eligible for military training, and some of the survey items include venereal tests using semen samples .
A group of researchers from Tina Kold Jensen, a professor of environmental medicine at the University of Southern Denmark, concluded with a consent from 1679 males, an average age of 18.9 years, who had been tested for conscription between 2012 and 2017 and collected semen samples. Sampling. In addition, the subjects were asked to undergo a physical examination to check the testis volume, diet, dietary supplements, lifestyle, alcohol consumption, smoking habits, marijuana use. A questionnaire was conducted to confirm the history and whether or not the mother smoked while in the womb.
A study group analyzed the results of physical examinations and questionnaires, and found that men taking fish oil supplements tended to have higher testicular function. Specifically, those who "have taken fish oil supplements for less than 60 days in the past three months" have 0.38 ml more semen than those who have not taken the supplement at all. In addition, it has been found that those who have taken fish oil supplements for the past three months have taken 60 days or more have 0.64 ml more semen than those who have not taken them at all.
Below is a graph showing the results, the vertical axis is the amount of semen, the horizontal axis is from the left “ People who have not taken fish oil supplements in the past 3 months '' “ People who have taken less than 60 days '' “ 60 Shows people over days. "
Similarly, testis volume was 0.8 ml higher for those who took “ fish oil supplements for less than 60 days '' than those who did not, and 1.5 ml for those who took “ 60 days or more '' than those who did not. That is.
The research team has also found that those taking fish oil supplements have higher sperm counts and a higher percentage of sperm with normal motility. Also, those who took supplements other than fish oil supplements such as multivitamin also reported a slightly higher total sperm count than those who did not.
Jensen told Reuters that "fish oil supplements are abundant.Omega-3 fatty acidsPlays an important role in the production of sperm cell membranes, but cannot be synthesized in the body and must be taken from the diet, '' he said, saying that omega-3 fatty acids improve testicular function. Was.
On the other hand, some studies are cautious about the study, which has a small population and has not been analyzed for non-supplementary diets. “ In Jensen's study, the appropriateRandomized controlled trialThere has been no causal link between fish oil and testicular function. " He pointed out that further research is needed to find out if fish oil supplements increase semen volume and sperm count.
