Will the hot weather affect the survival rate of sperm?

Disease analysis: Male sperm will change with the seasons. Some analysis shows that the proportion of immature sperm in summer is higher than that in other seasons. This is because the temperature is generally high in summer and the heat resistance of sperm is poor. Although it is easy to make male sperm tail defective in winter, the degree is not as serious as that in spring. Generally speaking, the number of sperm is the highest in winter, followed by spring, and the strongest sperm automaticity is in autumn and winter. Necrosis refers to many semen tests. Sperm morphology is normal and the density is within the normal range, but most sperm die. Under normal circumstances, more than 70% of normal sperm should survive within 1 hour after the semen is excreted. If the dead sperm exceeds 40%, it will affect pregnancy. Sperm survival time should be kept above 6 hours and 20%. If there is no live sperm within 6 hours, it may lead to infertility. Sperm activity is directly related to fructose contained in seminal vesicle. Fructose is reduced, nutrition is deficient, and sperm mortality is higher. In addition, the lack of vitamins A and E also has a great influence on sperm activity. A certain amount of abnormal sperm inevitably exists in sperm. Generally speaking, 10% can be called normal, and if it exceeds 10% or even reaches 20%, it will affect fertility, because this situation is often accompanied by semen quality problems such as poor liquefaction and low vitality. Suggestion: Sperm is very sensitive to warmth. The scrotum temperature is between 33 degrees Celsius and 37 degrees Celsius, which is the suitability of sperm survival. Once this temperature is exceeded, the quality and quantity of semen will be affected.
