Would it be bad for sperm and eggs? I heard that sperm are afraid of heat.

1. High temperature affects sperm survival

Sperm must be at a temperature 3-5℃ lower than normal body temperature, that is, generally speaking, the most suitable temperature for male testicles is 34℃- A large amount of healthy sperm can be produced between 35.5℃ and 35.5℃. If the temperature of the testicles reaches 36 degrees or higher, it will definitely cause heat stroke to the sperm, which will affect the quality of the sperm and even cause male infertility.

Experts remind that working in a high temperature environment for a long time will definitely affect the survival rate of sperm. Therefore, some men with occupations such as chefs and drivers need to pay more attention to heat dissipation in summer to prevent their testicles from being exposed to high temperatures for a long time.

2. The scrotum regulates the temperature of sperm

The testicles in the scrotum are where sperm are produced, and the epididymis is where sperm is stored. Under normal circumstances, the scrotum acts like a temperature regulator. When the temperature decreases, the skin of the scrotum contracts and thickens, bringing the testicles closer to the body, and the temperature of the environment around the testicles increases.

When the temperature rises, the skin of the scrotum relaxes and becomes thinner, and the testicles sag and leave the body, strengthening the heat dissipation function, lowering the ambient temperature around the testicles, and basically keeping the temperature in the scrotum stable at 32 degrees Celsius to 33 degrees Celsius. degrees Celsius.

3. Mr. Sperm suffered a heat stroke, and the consequences were very serious

Under normal circumstances, the testicles produce about hundreds of millions of sperm every day, and the testicles are extremely sensitive to the influence of temperature. Once the testicles If the ambient temperature rises abnormally for some reason, the testicular spermatogenic function may be impaired or the testicular spermatogenic epithelial cells may degenerate, resulting in abnormal semen.

High temperature damages sperm, which is mainly manifested as a decrease in sperm density in semen, a decrease in sperm motility, an increase in abnormal sperm, and even azoospermia in severe cases. Due to the above-mentioned changes in semen quality, the fertilizing ability of semen is reduced, which often leads to infertility.

High temperature weather: How to protect sperm?

High temperature is a cruel test of survival for sperm, while "low temperature environment" is the best breeding space for sperm. Therefore, in the hot summer, if you have the conditions, you must protect your sperm, and if you do not, you must create conditions to protect your sperm. If you want to become a "father", you must pay attention to the following points:

1. Refuse to use saunas

The optimal temperature for male testicles to produce sperm is between 34°C and 35.5°C. If this temperature is reached or exceeded, the production of spermatocytes will be inhibited, and at the same time, the motility of the sperm that has been produced will decrease.

Saunas, steam rooms, hot water sitz baths, and recently reported car electric heating devices will increase the temperature of the male scrotum, causing the testicles to remain in a high temperature state for a long time. When the testicular temperature is higher than 40°C for a long time , sperm motility will be greatly reduced.

2. Do not wear tight pants

Many men like to wear jeans, giving people a chic and uninhibited feeling, while some men like to wear tight underwear, but if you are People who sit in the office or drive for a long time should pay extra attention when wearing this kind of clothes. Jeans and tight underwear will hinder the blood circulation of the testicles and increase the temperature around the testicles by an average of 3.5℃!

Therefore, men should wear these in hot seasons. Wear loose, breathable cotton underwear, no tight pants such as jeans.

3. Life tips to prevent sperm heatstroke

In addition, there are some details in life that can help prevent spermatozoa from suffering from high temperature heatstroke. You should remember to act with caution: such as drinking more in summer Water is helpful to improve sperm quality; do not sit on hot beaches or stone benches when working in the open air or taking a break during travel; long-distance bus drivers or those working in offices without air conditioning should use ventilation and cooling material seat cushions on soft seat cushions; chefs, Pastry chefs should pay attention to heat insulation protection of their lower body when operating the stove.
