How normal is the male sperm vitality value?

1, sports ability: the sports ability of male sperm can be divided into four levels from slow to fast. Generally, sperm above grade 3 can fertilize eggs.

2. Sperm density The sperm density of normal people is 20 million-1.500 million /ml, which varies greatly among individuals. If the total number of sperm discharged each time is less than 20 million/ml, it is basically impossible to conceive naturally.

3. Look at the color: generally, the color of normal semen is grayish white or yellowish; If the semen is bloodshot and turns red or pink, it is bloody semen; If semen contains yellow secretion, it is purulent semen, which is abnormal.

4. Check semen volume: In our daily life, the ejaculation volume of normal people is generally around 2-6 ml. If there is 1-2ml, it is considered as a suspicious anomaly. If it is less than 1 ml or more than 7 ml, it can be considered as abnormal.

5. Liquefaction: Under normal conditions in after ejaculation, the human body is jelly-like, because it will become a less viscous liquid after about half an hour under the action of seminal vesicle coagulase. If it hasn't liquefied for more than half an hour, it means that sperm can't move freely, leading to male infertility.

6. Survival rate: Generally, within one hour in after ejaculation, the mobile sperm should be no less than 70% (generally 60-80%). If it is less than 60%, it is asthenospermia; If all the sperm in semen die, it is azoospermia.

7. Deformity rate: The head of normal sperm is flat and oval, and the tail is long and curved, similar to tadpoles; If there are double heads, big heads or sharp heads, these are abnormal, and more than 30% of abnormal sperm will lead to infertility.

8. PH Our normal semen pH is between 7.2 and 7.8. Too strong acidity or alkalinity is not conducive to sperm activity and metabolism, so it will also reduce sperm vitality.
