What is the survival rate of male sperm?

Men ‘s sperm are vital, lack of nutrition, insufficient support, changes in pH, infection of accessory glands and vas deferens, etc. will all affect the survival rate of sperm. The survival rate of sperm can reach 70% within an hour. The survival rate of the sperm is normal. One hour after ejaculation, the viable sperm should be above 70%. If the viable sperm is less than 50%, it is abnormal.

How much normal sperm survival rate? Causes and treatment of poor sperm survival. There are five main causes of low sperm viability in men, with different causes and different treatments.

1. Reproductive system infection: Reproductive system infection can lead to inflammation of the reproductive system, such as prostatitis , seminal vesiculitis, epididymitis, and urethritis. It is not conducive to the activity and survival of sperm. Jiang Hualong, Department of Urology , Donghua Hospital , Dongguan City

2. Varicocele: On the one hand, varicocele causes testicular hypoxia due to venous return obstruction, and on the other hand, prostaglandins, 5-hydroxytryptamine, etc., can cause damage to the seminiferous epithelium of the testicular seminiferous tubules and the testicular interstitium, and reduce the spermatogenic function and androgen-producing function of the testis. Varicocele causes the local temperature of the scrotum to rise, which will also reduce the survival rate of sperm.

3. The production of anti-sperm antibodies: anti-sperm antibodies are the “self-defense” produced by men themselves, causing the immune system to produce antibodies, causing sperm to agglutinate or brake, making it difficult for sperm to survive, resulting in a low sperm survival rate.

4. Blockage of testicular development: the testicular seminiferous epithelium is not fully mature or damaged, and the sperm quality is poor and the vitality is weakened.

5. Lack of trace elements: Zinc is an essential trace element for the human body, especially in testicular development, sperm formation, and maintenance of sperm vitality. Selenium plays an important role in the human enzyme system and immune system. It is an important component of glutathione peroxidase in the seminal plasma (this enzyme can prevent the sperm membrane from forming peroxidized lipids), and can neutralize the effects of cadmium and mercury on the reproductive organs. toxicity. The lack of these two trace elements will lead to low sperm survival rate.

The low sperm survival rate may be caused by one or more of the above reasons. The condition must be clarified and treated according to the cause in order to have a good effect.

How much normal sperm survival rate? Stay away from bad living habits and improve sperm survival rate

1. Smoking and alcoholism: Nicotine in cigarettes can not only reduce the secretion of sex hormones in men, but also has the ability to directly kill sperm. If you drink a lot of alcohol for a long time, alcohol will cause 70% of sperm to be stunted or lose their vitality.

2. Frequent intercourse: Frequent intercourse will reduce the amount of sperm in each ejaculation . If there are less than 20 million sperm per milliliter of semen, the chance of pregnancy will be very small.

3. Long-term soaking in hot baths and saunas: Only under normal circumstances can the testes produce normal sperm. If a man has a habit of taking a hot bath, it will reduce sperm production.

4. Picky eaters and hunger: Some men are picky eaters and don’t like to eat animal foods. Zinc deficiency in men will lead to decreased libido and sexual function, and decreased sperm count.

5. Radiation in work and life: Those who are in the media , computers and other related machines with excessive radiation such as computers for a long time, receiving high-dose radiation exposure can cause sperm chromosome aberrations.
