Men who love soy products such as tofu should be careful. According to a number of media reports in the United States recently, the Harvard University School of Public Health, a new study once again made it clear that if Eating soy products every day, will significantly reduce the number of male sperm.
The study was completed by Dr. George chavaro from the School of Public Health at Harvard University. From 2000 to 2006, the researchers tracked 99 men. Surprising results: men who eat soy products each day, each ml of semen, only 41 million sperm, significantly lower than men who eat less soy products. It is understood that the number of sperm in each ml of semen is less than 20 million, the sperm concentration is too low, easy to infertility. In addition, this relationship is more evident in obese men.
Chavaro believes that soy products have adverse effects on male reproductive systems, especially sperm production. Soy and its products are rich in flavonoids. If the intake is too high, it will naturally affect the level of male hormones in men, leading to a series of adverse consequences.
Chinese experts have suggested that eating too many soy products will affect the number of male sperm. In the past five years, Pan lianjun, a male doctor in Nanjing Maternal and Child Health Center, has been paying attention to this issue. He also found that men who often eat soy products are 3.46 times more likely to suffer from erectile dysfunction than men who do not often eat soy products.
