Many husbands and wives after many years of marriage have not been successful, and many older thoughts believe that the problem is in women.As everyone knows, the current society, male infertility is also the vast majority.So which are the causes of male infertility?Let's take a look at the knowledge about infertility.
1. Infertility caused, including, premature ejaculation, nocturnal emission, nocturnal emission, ejaculation cannot ejaculate, etc., which are relatively large for male infertility.
2. The cause of infertility caused by immunology is that there is anti -sperm antibody in serum or sperm plasma in men's serum or sperm, which produces its own anti -sperm immune response and cause immune infertility.
3. Some male infertility is caused by genetic defects.This defective gene plays a decisive role in the breeding genetic material DNA in the granular body.Studies have found that the sperm of men with a mutant gene not only weak exercise ability, but also many of them have defects and deformation, which leads to spouse infertility.
4. Lack of stem cells, cells in testicles are called stem cells. They experience sperm occurring and mature, and the process of generating sperm cells.The new study believes that this process is around a molecule called GDNF.This molecular is generated by another type of cells in the testicles, that is, cells in the testicular tube, which prompts stem cells to transform into sperm cells.Mouses with low levels of GDNF trained by genetic engineering do not produce any stem cells, so it is impossible to produce sperm.Many male infertility is caused by the lack of stem cells.
The above is the specific explanation of the cause of male infertility. The problem of male infertility in today's society is a more concerned focus. I hope that patients with patients who have not yet bred can introduce checking and treatment as early as possible, and do not miss the best period of breeding.If you have other male infertility, you can consult an expert.
