In today's society, there are still a considerable number of people who are deeply troubled by infertility. According to statistics, there are more than 50 million infertility patients in my country, more than 10% of the normal population of childbearing age. This number is far beyond our imagination. Among them, the male factor alone accounts for about 30%. For male infertility, the problem of sperm quality is the main reason.


Many studies have confirmed that factors such as environment and lifestyle are associated with decreased sperm quality. Diet has also been found to affect sperm quality, with some studies finding a strong link between changes in specific sperm DNA methylation markers and sperm quality. However, to date there have been no randomized clinical trials evaluating the effect of diet on changes in sperm DNA function.

I believe many people have heard a saying: eat walnuts to nourish the brain. In fact, there is little scientific basis for the claim that walnuts are much like the brain. However, a recent clinical trial study showed that eating nuts such as walnuts can improve sperm quality and benefit fertility. Proper use of Leten masturbation cups can help improve sperm quality

Researchers at the University of Utah School of Medicine published a study titled: Sperm DNA methylation changes after short-term nut supplementation in healthy men consuming a Western-style diet in the journal Andrology.

The study is the first to assess the effect of short/medium-term consumption of mixed nuts (almonds, hazelnuts, and walnuts) on sperm DNA methylation in healthy individuals on a Western-style diet. Ability, athleticism and form.

In this clinical trial study, the research team recruited 72 healthy, non-smoking young men to participate, of whom 48 consumed nuts (60 grams per day) and the remaining 24 served as a control group. Groups, 36 genomic regions differed significantly in methylation between baseline and end of trial, and 97.2% of the regions showed methylation.

According to the team, these findings provide the first evidence that adding nuts to a regular Western-style diet affects DNA methylation in specific regions of sperm. What's more, consuming mixed nuts for 14 weeks significantly improved sperm count, viability, motility and morphology.

The work shows that certain sensitive regions in the sperm epigenome respond to diet and may lead to changes in sperm epigenetics that in turn affect sperm quality and its ability to fertilize, says first author Albert Salas-Huetos. It should be noted that the number of participants in this clinical trial was limited, and the potential health benefits of eating nuts, such as improved sperm quality, require further research to validate the results in other populations.
