Sperm chromosome examination items

Sperm chromosomes affect the physical characteristics of our offspring. Everyone has a family and everyone will pass on the family line, so everyone will have sex. Sex between men and women allows the sperm and egg to combine, and then the female friend can become pregnant. This then involves the issue of the male friend's sperm chromosomes. The genes on the chromosomes determine the height, weight, and other aspects of the child to be born. Perhaps everyone doesn't know much about sperm chromosomes in this regard, so let's learn about the relevant content below.

Check items:

1. Semen volume:

It is necessary to check the total amount of semen discharged by male friends in one ejaculation. Under normal circumstances, a normal man can discharge 1.5 ml to 6.0 ml.

2. Sperm count (concentration or density):

It is necessary to check how many sperm are in each milliliter of male semen. Under normal circumstances, the number of sperm in male semen is 20 million/ml.

3. Sperm motility:

It is necessary to check the active sperm in the semen of male friends. In the semen of normal male friends, at least 60% of every 100 sperm should be active sperm.

4. Acidity and alkalinity (PH value):

It is also necessary to check the pH value of sperm. Normally, the pH value of male sperm should be kept between 7.0 and 7.8. If the pH value of sperm is less than 7 or greater than 8, it means that the male's sperm motility has decreased significantly.

5. Color:

Normal male semen is milky white or grayish white. If the semen is yellow-green, it means that the man has genital tract infection.

Premarital examination can find abnormal chromosome carriers with normal phenotype, such as balanced chromosome translocation and inversion. Balanced chromosome translocation and inversion have normal phenotype because the gene is not lost, but it is very easy to cause miscarriage, malformation, and stillbirth. Blindly preserving the fetus will increase the birth rate of malformed babies. Premarital examination can also find patients with basically normal phenotype but abnormal sex chromosomes. These patients may show sexual dysfunction and infertility. Therefore, premarital examination is of great significance to eugenics.

The above content introduces us to the relevant content of sperm chromosomes. Through the above content, we can grasp the more specific content of conception. We should think about our future generations and allow sperm with a better survival rate to combine with eggs to improve the sperm survival rate and increase the chance of conception.
