In recent years, clinical practice in urology and andrology clinics has also seen that declining sperm quality has led to more and more patients seeking treatment for male infertility. Reasons for the decline in sperm quality include congenital or acquired diseases, and some are caused by human factors in life. Among them, the following 5 factors have been proven in research to have the greatest impact on sperm quality.

Five sperm killers in daily life

1. Sex toys. Sex toys made of vinyl, such as vibrators and masturbators, can release phthalates. Phthalates, plastic softeners, may harm sperm and more.

2. Agricultural products treated with pesticides. Produce must be washed thoroughly before consumption. Chemical pesticides kill both crop pests and sperm with little effort.

3. Pesticides. Not only on the surface of food, but also in the food. Therefore, it is best to choose organic agricultural products that do not use chemical fertilizers and pesticides in the production process.

4. Car heated seat cushions. Although using a heated car seat is very comfortable, it can cause the male genitals to become extremely hot, which can damage sperm quality. In addition, taking a hot bath for too long will also cause the testicular temperature to be too high, hindering normal sperm production.

5. Contaminated fish. Toxic chemicals PCBs can accumulate in fish's bodies. This substance is harmful to sperm. It is best not to eat fish from polluted water bodies. Experts say that if you particularly like to eat fish, then deep-sea fish, especially wild salmon, is the best choice.

Are the 7 folk legends about spermicide true?

There is not much difference between briefs and boxers

Many people believe that wearing briefs will increase the temperature of the scrotum and damage sperm compared with boxer briefs. There is actually no need to worry about this. In 1998, New York University conducted a study and found that no matter what kind of underwear you wear, the impact on the scrotum is similar. Experts suggest that you don’t need to put too much thought into choosing the style of underwear. Instead, you should allow your scrotum to be ventilated and breathable.

Don’t put your laptop on your lap

A 2005 New York University study found that using a laptop on your knees for a long time can significantly increase scrotal temperature. However, scientists are still studying whether radio waves emitted by electronic devices such as mobile phones or music players have adverse effects on sperm. The safer way is to try not to keep them in your pants pockets for a long time.

Hot baths are a taboo

Hot baths and saunas are both "murderers" that will definitely affect the quantity and quality of sperm. Generally, once a week is a more appropriate frequency.

Obesity

The impact of overweight on testicular function is mainly reflected in two aspects: First, obese people will convert more testosterone into estradiol, thus affecting the number and quality of sperm; on the other hand, too thick adipose tissue near the testicles will also cause Can cause scrotal temperature to rise. Therefore, if you want good sperm quality, it is imperative to lose weight.

Narcotics

Research has shown that anesthetics and other drugs can damage male endocrine, and long-term use of painkillers can also produce such side effects. Therefore, even over-the-counter medications should be taken with caution.

Eating red meat does not affect sperm quality

Researchers analyzed multiple previous trials and found no clear evidence to support a link. But your best option is to eat more fish.

Aging

As a man ages, the quantity and quality of his sperm decrease. If the parents are older, the risk of the newborn having Down syndrome and schizophrenia increases. But overall, the impact of aging on men is not as great as on women, and men in their seventies or eighties can still be fathers.
