Sperm and egg combine to produce a human being. However, once generated, sperm face aging, and the outward characteristics of aging sperm are malformed sperm. Thus the sperm malformation rate in the semen quality analysis report arises. The process of sperm production is quite complex. The production of sperm is regulated by the endocrine system. Each spermatogonial cell can become 4 spermatozoa, and the 4 spermatozoa multiply exponentially, producing a total of about 200-400 million spermatozoa per day in a person. The growth of sperm in the varicocele takes about 3 months and days, and many reasons can lead to sperm malformation during the approximately 90 days of sperm production and maturation: 1. chromosomal abnormalities cause malformed sperm. 2. environmental factors, long-term high heat in the scrotum, long-term alcohol abuse can damage the function of spermatogenic cells in the testes and interfere with sperm growth and maturation, thus leading to sperm malformation. The irradiation of radiation can cause mutation of sperm, resulting in deformed sperm. 3, infectious diseases of the genitourinary tract, mumps complicated by orchitis, congenital testicular hypoplasia, chronic poisoning, tuberculosis of the epididymis, excessive mental tension, malnutrition, excessive sexual life, varicocele, etc. can affect the process of spermatogenesis. 4, the use of hormones or certain chemical drugs, such as: frequent use of sedative drugs, Anti-tumor drugs, chemical drugs in Maryland, furan drugs, hormonal drugs also have a disturbing effect on the division of spermatogonia and sperm maturation, is a common cause of high malformed sperm. The most crucial thing is that after a couple has sex, the sperm have to go through a long-distance race and only the high masters among the best have the chance to get to rendezvous with the egg to conceive a healthy little baby. So the sperm malformation rate has little effect on pregnancy.
