1. Laptop computer. Will laptops with wireless networks affect sperm quantity and quality? According to a study published in the journal Fertility and Infertility, researchers stored sperm from 29 men normally and placed them under laptops with wireless connections. As a result, sperm activity under the computer decreased and DNA was more damaged. However, some experts say that the impact of computers on sperm still needs further research.
2. Soda water. There are rumors that artificial pigments or high levels of caffeine in soda water can harm sperm. Experts say that from a health perspective alone, people should drink less soda water, but there is currently no conclusive evidence that its ingredients can cause infertility.
3. Take a hot bath. Although prolonged high temperatures may affect sperm quantity and quality, there is indeed a correlation between high scrotal temperature and decreased sperm quantity, but moderate hot baths are harmless unless they are taken for too long a day.
4. Wear briefs. Pants are often referred to as sperm "killers" because they tightly wrap the testicles and even make them stick to the body. However, this claim has no medical basis, and the impact of briefs on men's health can be negligible.
5. Ride a bicycle. Does frequent cycling kill sperm? A study of Spanish triathletes found that their sperm count and quality were lower than those of other non cyclists. Some experts say other studies have also found similar conclusions that long-distance bicycle racing can harm the sperm.
6. Mobile phone. Researchers at the University of California, Berkeley, reviewed several studies on whether mobile phones harm sperm. Eight out of nine studies have shown that mobile phones have a negative impact on sperm counts, especially when they are often kept in pants pockets. Experts say the electromagnetic radiation emitted by mobile phones may have a negative impact on the cells necessary for testicular sperm production.
7. Cash register receipt. Holding a cash register receipt for 10 seconds can cause 2.5 micrograms of bisphenol A to stain the skin. Bisphenol A can interfere with the endocrine system, and heavy exposure may have adverse effects on male fertility. However, no research has shown that keeping receipts in your pocket can affect male fertility, but you should still pay attention to washing 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 the quantity and quality of their sperm. Other studies have shown that smoking can even have a negative impact on sperm chromosomes.
