How to distinguish the healthiest sperm?

Semen examination is a preliminary examination, which can generally check whether semen is abnormal. Routine semen examination should include semen volume, semen liquefaction degree, viscosity, sperm count, sperm viability, vitality, sperm viability and sperm morphology. 1, semen volume: every time a normal male ejaculates, the semen volume is not less than 2ml. Usually, the lack of semen is often due to the loss of a part of semen. 2. Color of semen: Normal semen is even in texture and grayish white. When you don't ejaculate for a long time, the semen is slightly yellow. If the sperm density is low, the semen will appear thinner. Other colors usually indicate that something is abnormal and need further inspection. 3. Liquefaction time: At normal temperature, the semen will solidify immediately after being excreted, and then liquefy within 15 minutes. If semen does not liquefy for more than 60 minutes, it should be regarded as abnormal. If the liquefaction time of semen is prolonged, the liquefaction is incomplete or not, which is usually related to the low secretion function of prostate. 4.pH value: The pH value shall be measured within 65438 0 hours in after ejaculation. Normal semen is slightly alkaline, acidic reduces sperm activity, and alkalization increases sperm activity. Inflammation of accessory gonads will affect the pH value of semen. 5. Viscosity: Semen after normal liquefaction is a thin liquid. 6. Agglutination: When observing semen under a microscope, you can see that most sperm are scattered and swim freely. When sperm coagulates into a ball, it means that there are probably anti-sperm antibodies in semen. 7. Sperm density and total number: The normal density of sperm should be more than 20 million per milliliter. Less than 20 million /ml is mild oligozoospermia, 5 to 20 million /ml is moderate oligozoospermia, and less than 5 million /ml is severe oligozoospermia. But everyone's specific situation is different, even the same person at different times, the density will be very different, so it is unreasonable to draw a conclusion just once. 8. Sperm motility and motility: Sperm motility can be divided into four levels: A, B, C and D. Generally speaking, in terms of sperm density and motility, the infertility rate of those with two abnormalities is significantly higher than that of those with only one abnormality. 9. Sperm morphology: Abnormal sperm morphology usually indicates low reproductive capacity, which greatly reduces the chances of pregnancy. 10, white blood cells and red blood cells: There may be a small amount of white blood cells in semen, but no red blood cells. If there are too many white blood cells or red blood cells, there may be inflammation of the reproductive system. Qingdao Yan 'an Third Road 10 1, I wish you a healthy life at an early date.
