Why are more and more couples who are eager to have children asking for help from doctors? There are certainly many reasons, but one important reason is that the physical quality of the husband’s tadpoles is not up to standard …… cover your mouth and nose, beware of toxic! Environmental pollution can damage sperm, we all know that pesticides, heavy metals, cigarette smoke, etc. will cause a decline in sperm quality, in addition to the following types of substances you notice? Anti-cancer drugs: some clinically used drugs such as cyclophosphamide, mitomycin C and vincristine can cause apoptosis of spermatocytes in rats and mice. Long-term use of cyclophosphamide can lead to testicular atrophy and sperm reduction in men. Of course, if this anti-cancer drug is used by women, it can cause menopause, and if it is taken by pregnant women, there is a risk of malformed lesions in the fetus. Also, in the treatment of prostate cancer, it is possible to use a drug called ethylene estradiol, which can also trigger apoptosis of germ cells. However, in order to cure cancer, there is no need to care so much. Environmental estrogens: Simply put, these substances produce estrogen-like effects, and if they enter the male body in large quantities, they can lead to disruptions in the endocrine system, which can affect sperm production. Garbage incineration has been controversial, and many people know that the dif-ing produced by combustion causes cancer. In fact, this substance is also a kind of environmental estrogen, which can counterfeit estrogen involved in the process of cell signaling and gene expression, leading to endocrine disorders and affecting sperm production. The aforementioned anti-cancer drug ethylene estradiol is actually also an environmental estrogen, which is synthetic and can act not only on adult males, but is even toxic to male babies still in their mothers’ wombs, and the rate of testicular abnormalities in fetuses after birth is significantly higher than in normal children. High temperature, radiation, these I do not say we all know is not a good thing. The question is, is all radiation should be careful? At present, there is definite evidence to confirm that it is harmful to humans, only X-rays, radiation from radioactive substances in substandard marble materials, cosmic rays and other ionizing radiation. For cell phones and other electromagnetic radiation, there is no conclusive evidence to prove that harmful to humans, gay men can feel free to play the phone. In addition, noise, vibration, microwaves are also believed to have a hindering effect on spermatogenesis. The beast here is actually talking about pathogenic microorganisms. Organisms such as Chlamydia trachomatis and Mycoplasma pneumoniae, which appear to be unrelated to reproduction, can actually have a detrimental effect on spermatogenesis. For example, Chlamydia trachomatis infection can make sperm morphology abnormal, and it can also latch onto the surface of sperm and interfere with sperm swimming. They can also get inside the sperm and multiply in the sperm, leading to sperm destruction. In addition, when men are infected by Chlamydia trachomatis, it leads to an increase in white blood cells, which appear to engulf the sperm. In this way, the total number, quality and motility of sperm are reduced. Men are tough, but sperm are fragile, and there are just too many things that can harm these tadpoles, so for the sake of their own health and that of the next generation, men must stay away from all those things that can make tadpoles go wrong as much as possible.
