"Creating people" in summer is difficult high
There is no appetite for eating, and there is no strength to work. As soon as he leaves the air -conditioned room, he is dizzy. Many citizens in Hangzhou have such symptoms of summer summer, and the impact of high temperature weather on people is really great.But what other effects does high temperature weather have on people?A few days ago, the reporter obtained a set of survey data to confirm that the summer, spring, and autumn are the worst quality than winter, spring, and autumn.This result was published in the recent Chinese male science magazine.Doctors suggested that the best season for eugenics is spring and autumn.
This research was done by the Men's Research Office of the Institute of Family Planning and Technology of Zhejiang Province. It was selected from September 2006 to June 2008. 6414 semen samples of 1,135 sperm -oriented volunteers in Zhejiang Human Sperm Studio were selected., According to the essence time, it is divided into spring, summer, autumn, and winter groups.As a result, the semen volume in the spring is up to 2.92 ml, which is significantly higher than the three seasons of summer, autumn, and winter, and only 2.71 ml in summer.Sperm density, up to 105.6 × 106/ml in autumn, the worst is summer, 93.54 × 106/ml.
High sperm quality in spring
Yao Kangshou, director of the laboratory and reproductive expert, said that seasonal factors have an impact on semen parameters of sperm supply volunteers. The amount of semen in spring and high percentage of forward exercise sperm is the best season for sperm donation.Most of these parameters in summer lag behind three seasons.In other words, the quality of sperm in summer is the lowest.
Why is there such an impact?Experts say that the impact of seasonal changes on semen quality may mainly affect the occurrence of sperm through temperature, and seasonal temperatures have an effect on testicular function.
The percentage of normal sperm morphology in summer is lower than that of other seasons, and the lower the proportion of sperm in normal form, and the lower the chance of the spouse's conception.
"Sperm quality in spring is high and the surrogacy rate is high, which is in line with the laws of animal estrus in the spring of animals. But the poor sperm quality in summer may be related to many factors." Yao Kangshou said.
The temperature in summer is high, and the body temperature of the human body is also higher, which has an impact on the testicles and may affect sperm quality.In addition, the summer rest is not good, the quality of sleep is poor, and it may also affect fertility.
In fact, it is even more worried about experts that the impact of environmental pollution on male sperm quality.In our living environment, pesticides, fertilizers, and plastic products contain estrogen -like substances. Many studies have confirmed that these substances have damaged men's sperm.
