Endocrine factors – in normal male seminal plasma, estrogen levels are significantly higher than serum estrogen levels. This both indicates local estrogen production and implies that the testosterone/estrogen balance plays an important role in normal male spermatogenesis .
Environmental changes—including air pollution, occupational exposure, and living habits—can affect semen quality. Work environment also had a significant impact on semen quality. The history of exposure to various toxic substances is an important factor leading to the reduction of male fertility. Long-term exposure to pesticides (such as insecticides) also had a significant effect on sperm morphology, resulting in a significantly lower rate of morphologically normal sperm.
Microbial factors—Leukocytes can be found in both the male genital tract and ejaculated semen. Increased white blood cell concentration in semen can lead to decreased semen quality. In addition, bacteria, mycoplasma, chlamydia, viruses, etc. can also cause semen infection, which can lead to changes in semen quality (motility, pH, shape).
Guidance: Protect sperm and eat more foods such as beans
