The threat of being infertile generally in the case of males can get elevated when they get exposed to radiation. Getting exposed to radiation can result in a reduction in the production of sperms. In normal dose, the count of sperms could ultimately get back to its usual concentrations, however, with higher doses and lengthened exposures to radiation, the production of sperm can get reduced permanently.
Other environmental threats, which could enhance the chances of infertility in males are getting exposed to industrial chemicals, heavy metal exposure, and overheating of the testicles, which takes place due to wearing tight clothing or sitting for long duration.
