There are too many DINK families nowadays, but many DINK families are not because they do not want children, but because they cannot have children. Most of the reasons for not having children in families are due to male infertility certificates, which have a great impact on men. Therefore, we need to know the reasons for infertility.
Abnormal testicles leading to infertility
Including: acquired injuries: such as hernia repair surgery, hydrocele surgery, testicular fixation surgery, etc. that damage testicular blood vessels; Fetal damage to the embryonic primordia and early testicular damage due to adverse environmental factors can be caused by injury during childbirth.
Immune factors leading to infertility
Because sperm is exposed to the immune system, sperm seminal plasma produces antibodies against its own sperm in the body, and the ejaculated spermatogenesis agglutinates itself and cannot make women pregnant.
Respiratory system diseases leading to infertility
For example, Young's syndrome and Kartagner's syndrome both result in infertility due to abnormalities in the ultrastructure of respiratory mucosal cilia and sperm tails.
Infertility caused by hydrocele of the tunica vaginalis
The accumulation of fluid in the tunica vaginalis compresses the blood circulation of the testicles, which can lead to testicular infection or atrophy. The incidence rate of the disease after puberty is 16% - 19%.
Environmental impact leading to infertility
Miners, boiler workers, etc. who overheat in the tunnel; Underwear is too tight; Excessive smoking and drinking; Under hypoxic conditions, it can affect fertility.
