What are the causes of male infertility

summary

My sister has been married for several years, but she has no children. Recently, I was in a hurry at home, so I accompanied my sister to the hospital for examination. I didn't expect that the doctor said that there was something wrong with my sister's vas deferens. In order to prevent this situation, I'd like to introduce the causes of male infertility.

What are the causes of male infertility

Reason 1: abnormal semen: the number of sperm is too small, the vitality is weakened, and the morphology is abnormal. The factors that affect normal sperm production include: congenital dysplasia; systemic chronic wasting diseases, such as long-term malnutrition, chronic poisoning, frequent sexual life, etc. Local causes: orchitis leads to testicular atrophy, testicular tuberculosis causes testicular tissue damage, varicocele.

Reason 2: congenital organ abnormalities: some congenital malformations of sexual organs are difficult to correct, but if they can be found in time, early surgery in childhood can be corrected. However, due to the lack of knowledge and timely treatment, fertility decline or infertility are often caused.

Reason 3: sperm delivery blocked: epididymis and vas deferens tuberculosis can make vas deferens blocked, hinder sperm through, impotence and premature ejaculation patients often can not make sperm into the vagina.
