Why does sperm leak out on its own?

After every sexual intercourse, some sperm will always flow out. This is mainly because the semen is solidified just after ejaculation and slowly melts into liquid as the temperature rises. In this case, some sperm will definitely flow out. This is very normal and is not caused by poor health. People only need to pay special attention when the color and shape of the sperm are abnormal.

First, semen abnormalities are caused by urogenital system infection, such as urogenital tract inflammation caused by various bacteria, viruses, mycoplasma, parasites, tuberculosis, gonococci, etc.; second, semen abnormalities are caused by endocrine dysfunction, such as hypothalamus-pituitary-testicular axis dysfunction, hypothyroidism, hyperthyroidism, etc.; third, semen abnormalities are caused by varicocele; fourth, semen abnormalities are caused by congenital reproductive system abnormalities or genetic diseases; fifth, semen abnormalities are caused by external factors, such as medication, work, living environment and bad habits.

Sperm abnormalities include:

1. Oligospermia and hyperspermia: Generally, the normal sperm count in one semen is 20 million to 200 million/ml. A sperm count below 20 million/ml is oligospermia, and a sperm count exceeding 300 million/ml is hyperspermia.

2. Azoospermia: If no sperm is found in three semen examinations, it is azoospermia. Azoospermia is divided into two types: congenital azoospermia and obstructive azoospermia. The former refers to the atrophy and degeneration of testicular spermatogenic cells, which cannot produce sperm; the latter refers to the testicles being able to produce sperm, but the vas deferens is blocked and cannot be discharged.

3. Necrozoospermia: The survival rate of sperm in semen decreases. If more than 40% of dead sperm are found in semen examination, it is called necrospermia, also known as excessive necrospermia. However, if the number of dead sperm increases artificially due to improper examination methods or failure to collect semen according to normal methods, it is called pseudonecrospermia, which must be identified.

4. Sperm abnormality: The sperm in semen is more than 20% abnormal. The abnormal sperm include abnormal shape of head, body and tail, or mixed deformity of head and body.

5. Sperm agglutination syndrome: Due to the presence of sperm antibodies, sperms self-agglutinate. If sperm agglutination is found in both sperm agglutination test and post-coital test, it is sperm agglutination syndrome, which must be distinguished from seminal vesicle non-liquefaction syndrome.

6. Abnormal sperm motility: Sperm motility can be classified into 5 levels, with level 0 being no motility; level 1 being poor motility, with the sperm only able to move or rotate in place; level 2 being moderate motility; level 4 being very good motility, with the sperm actively moving forward in a straight line; and level 3 being between level 2 and level 4, indicating good sperm motility.
