Normal healthy value of male sperm

Some male friends will find that their semen has fewer sperm, lower motility or more deformed sperm during routine semen examinations. This is poor sperm quality, which makes it difficult for women to get pregnant or leads to infertility. If they are lucky enough to get pregnant, it is likely to cause stillbirth or deformed children, which is irresponsible to the next generation. Today we will take a look at the normal value of sperm.

Semen is composed of sperm and seminal plasma, of which sperm accounts for about 5% and the rest is seminal plasma. In addition to water, fructose, protein and fat, it also contains a variety of enzymes and inorganic salts. Sperm is produced by the testicles. The number of sperm in each milliliter of semen is generally between 60 million and 200 million. Motile sperm accounts for more than 60% of the total, and abnormal sperm accounts for less than 10% of the total. At room temperature, sperm motility lasts for 3-4 hours.

Factors that affect semen quality: Improper living habits

Undisciplined living habits can easily lead to male reproductive tract infection. Reproductive tract infection first affects the production and transport of sperm, causing oligospermia and resulting in decreased reproductive capacity. Reproductive tract infection can also cause changes in sperm motility. Reproductive tract infection can inhibit the secretion of accessory glands, causing a serious decrease in sperm motility and quantity, leading to infertility.

Smoking and drinking

Men are very sensitive to the toxins in tobacco and alcohol, especially reproductive cells. Studies have shown that nicotine in tobacco can reduce the secretion of sex hormones and kill sperm. Long-term alcohol abuse can damage the spermatogenic cells in the testicles, affecting sperm production.

Warm environment damages the testicles

Many men wear tight pants for a long time to show off their muscular bodies, which prevents the scrotal skin from dissipating heat, thereby increasing the local temperature of the testicles and hindering sperm production. The testicles are the organs that produce sperm. Frequent hot tub baths and saunas will keep the scrotum in a high temperature state, which will affect the spermatogenic function of the testicles.

Improper diet

Nutritional deficiencies, such as vitamin A deficiency, can lead to the failure of spermatogenic epithelium to grow; vitamin B deficiency can affect pituitary function and reduce fertility; vitamin C plays an important role in preventing semen coagulation and maintaining sperm motility; deficiency can cause testicular damage; calcium and phosphorus deficiency can reduce fertility; deficiency of trace elements zinc and magnesium can also affect sperm production and motility.

Drug damage

Modern medical research has shown that many drugs can cause male infertility. For example, cyclophosphamide can cause testicular spermatogenesis dysfunction; methotrexate can cause a decrease in sperm count and sperm motility; and cimetidine can indirectly reduce sperm motility by inhibiting the secretion of male hormones.

Excessive or inappropriate sexual activity

Although the testicles can produce tens to hundreds of millions of sperm every day, it takes 5 to 7 days for the sperm to mature and reach a sufficient number after one ejaculation. If you have sex too often or without restraint, the amount of sperm ejaculated each time is small, and it is naturally difficult to conceive.

Normal test of semen

1. Semen volume: 2 to 6 ml each time. More than 8 ml is called hyperseminal syndrome, and less than 1.5 ml is called hyposeminal syndrome.

2. Semen pH: 7.2-8.6, average 7.8.

3. Semen liquefaction: Complete liquefaction in 30 minutes. If it does not liquefy for more than 1 hour, it is called poor semen liquefaction syndrome.

4. Sperm count in semen: 60 million to 200 million per milliliter. Less than 20 million per milliliter is called oligospermia.

5. Sperm motility: Quantification of forward-moving sperm should be no less than 60% in the first hour and no less than 50% in the second hour.

6. Sperm survival rate: dead sperm does not exceed 50%.

7. Sperm morphology: Normal morphology of sperm is not less than 70%. If the test results of the semen sent for examination are significantly different from the above values, infertility should be suspected. Of course, we cannot draw a conclusion based on only one indicator. A comprehensive analysis should be conducted and re-examination should be conducted within 2 to 3 weeks before a diagnosis can be made.

Ways to improve semen quality

1. Eat more green vegetables. Green vegetables contain vitamin C, vitamin E, zinc, selenium and other ingredients that are beneficial to sperm growth. Nuts and fish are rich in omega-3 fatty acids and should also be eaten more to promote sperm cell growth.

2. Eat high-quality protein and arginine foods. High-quality protein is the main raw material for the formation of semen. Foods containing high protein include lean meat, pork spinal cord, dog meat, beef and mutton, chicken and duck, eggs, fish and shrimp, and soy products. Arginine is a necessary component for the production of sperm. When it is deficient, oligospermia may occur. Foods containing arginine include eels, black fish, sea cucumbers, tendons, soy products, lean meat, etc.

3. Quit smoking and drinking: Tobacco and alcohol are the nemesis of male fertility. Studies have shown that men who smoke and drink frequently are mostly infertile.

4. Exercise more. Exercise more, improve physical fitness, and stay away from obesity are the keys to male fertility. Studies have shown that excessive obesity in men will cause the temperature in the groin to rise, which will damage the growth of sperm and lead to infertility.

The above is the normal value of sperm and the test method and how to improve the quality of sperm. If you want to conceive, you must go to the hospital for examination with the woman. Don't be so irresponsible to the next generation and just have a child. Only normal sperm can produce healthy and normal children. Reduce the birth rate of deformed children.
