For men who are planning to make a baby, the quantity and quality of sperm is very important, and there are many rumors about exercises or behaviors that can harm sperm. Now to help you answer these claims one by one is right or wrong. 1. Laptop computers Do laptops with Wi-Fi have an impact on sperm count and quality? In a study published in the journal Fertility and Infertility, researchers took sperm from 29 men and stored it normally and placed it underneath a laptop computer with a wireless connection. As a result, the sperm underneath the computers had decreased motility and suffered greater DNA damage. However, the impact of computers on sperm still needs further study. 2, soda There are rumors that artificial colors or high levels of caffeine in soda can hurt sperm. From a health point of view alone, people should drink less soda, but there is no conclusive evidence that its ingredients will lead to infertility. 3, soak in a hot bath Although prolonged high temperatures may affect sperm quantity and quality, there is indeed a correlation between high temperatures in the scrotum area and a decrease in sperm count, but a moderate hot bath can’t hurt, unless the hot bath is too long every day. 4, wear pants pants are often said to be sperm “killer”, because it tightly wrapped testicles, and even make it stick to the body. However, there is no medical basis for this claim, and the effect of pants on men’s health is negligible. 5, bicycling Regular cycling will kill sperm? A study for Spanish triathletes found that their sperm count and quality were lower than other non-cyclists. Some experts say other studies have found similar conclusions that long-distance cycling races can hurt sperm. 6, cell phone University of California, Berkeley researchers on the cell phone whether to hurt the sperm of a number of studies conducted a review of the review. 8 of the 9 studies show that cell phones have a negative impact on the number of sperm, especially when the cell phone is often placed in the trouser pockets. Cell phones emit electromagnetic radiation, perhaps negatively affecting the cells necessary for sperm production in the testes. 7, cash register receipts Examining handheld cash register receipts for 10 seconds will make the skin stained with 2.5 micrograms of bisphenol A. Bisphenol A disrupts the endocrine system, and a large amount of exposure may adversely affect a man’s fertility. However, there is no research to suggest that putting receipts in your pocket will affect male fertility, but you should still wash your hands after taking them. 8. Smoking Smoking is associated with many health risks, including sperm damage. Over the years, several studies have found that men who are heavy smokers are more likely to have problems with sperm count and quality. Other studies have shown that smoking can even negatively affect the chromosomes of sperm.
