What is the normal sperm morphology?

About 200 million sperms are released, and finally only one sperm "breaks through the siege" and enters the egg, resulting in sperm-egg fusion, and life begins. High-quality sperm is the basis for the origin of life. But what kind of sperm is considered normal? What is the normal sperm shape?

The normal amount should be more than or equal to 2ml

If it exceeds 7ml, it is too much. At this time, not only the number of sperm is reduced, but it is also easy to be discharged from the female vagina, resulting in a decrease in the number of male sperm, which is more common in patients with seminal vesiculitis. On the contrary, if the total output is less than 2ml, it is less semen, and less than 1ml is too little, which is easy to cause infertility. The normal color is grayish white or slightly yellowish

If the semen is milky white or light green, it indicates inflammation of the male reproductive tract or the genital tract. If it is pink or bright red, or blood cells can be seen under a microscope, it is sedative semen, which is more common in patients with genital tract inflammation and posterior urethritis, and occasionally in patients with tuberculosis or tumors. If it does not evaporate within 30 minutes, it is abnormal.

After normal semen is ejaculated, it can become jelly under the condensation and hydrolysis of the seminal vesicles, and after 15 to 30 minutes, it becomes liquid under the vaporization and hydrolysis of the male prostate, which is called sperm liquefaction. If the semen still does not vaporize 30 minutes after ejaculation, it is considered abnormal.

It is normal for the length of sperm to be less than 2 cm

Use a glass rod to touch the vaporized semen, and gently lift it to produce semen threads. If the semen is normal, the length of the semen thread should be less than 2 cm.

pH value is 7.2--7.8

The normal pH value of semen is 7.2-7.8. A value lower than 7.2 is often seen in vas deferens obstruction or urine pollution; a value higher than 7.8 is often seen in seminal vesiculitis or poor specimen collection. The pH value of semen, sperm motility and other indicators need to be tested to obtain accurate results. If a man finds that the above four indicators are not normal, he should go to the hospital for further testing.

Survival rate ≥50%

Generally refers to the examination within 1 hour of male ejaculation, and the live sperm ≥ 50%. Common causes of reduced sperm motility and survival rate include parasexual hormone inflammation, varicose veins, microvilli stasis syndrome caused by chronic respiratory infection, anti-sperm antibodies in semen or improper sample collection and storage.

Male sperm count ≥ 20 periodontal 10 6/ml

It is usually expressed as the number of sperm in 1ml of semen. The normal count is ≥20 106/ml. A count below this value indicates too few sperm, which is often seen in spermatogenesis problems caused by various reasons. It may lead to low fertility or infertility due to the reduced chance of sperm entering the uterine body and bilateral fallopian tubes. If the sperm count exceeds 250 106/ml, it means too many sperm, which may also cause infertility due to the affected sperm motility.
