There are too many DINK families now, but many DINK families are not because they don't want children, but because they can't have children. Most of the reasons why families don't have children are due to male infertility certificates, which have a significant impact on men, so we need to know the reasons for infertility.
Testicular abnormalities lead to infertility
Including: acquired injury: such as hernia repair, hydrocele surgery, testicular fixation surgery, and other injuries to testicular blood vessels; During the fetal period, adverse environmental factors damage the embryo primordium and early testicular damage, which can be caused by injury during childbirth.
Immune factors lead to infertility
"Due to sperm exposure to the immune system, the sperm plasma produces antibodies in the body against its own sperm, and the ejaculated sperm agglutinates itself, preventing a woman from conceiving.".
Respiratory system diseases lead 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 due to hydrocele of the tunica vaginalis
The hydrocele of the tunica vaginalis compresses the blood circulation of the testis, 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 and boiler workers who are overheated in the tunnel; Underwear is too tight; Excessive smoking and drinking; Hypoxia can affect fertility.
