Guys, talk about those areas in chemical plants where unmarried men are not allowed to enter. As far as I know, there’s P, which poses a risk of killing men’s sperm
In that case, it’s better for the man to finish raising the child before going back to work at the factory
Fields that require work in high-temperature environments should be avoided as much as possible; high temperatures can affect the quality of sperm. For reference only. http://www.dlnk.org/html/bybyzk/rdgz_608290240044.html
After giving birth, what about those who haven’t given birth yet? Hasn’t everyone encountered this situation? After all, it concerns the next generation of the country
What temperature levels can have an impact? Are there any examples?
Try to spend as little time as possible in positions related to the deep processing of tar and crude benzene
