What can make a woman infertile or a man sterile? Is there anyway to help prevent this?
infertility can occur for a number of reasons. The most common causes are hormonal and this can indicate problems with the gonads or parts of the brain (the hypothalamus or the pituitary). In girls this is pretty obvious as they will have problems with their menstrual cycle. I will stop now before i get too technical!
I would say the best way to prevent infertility is to keep yourself safe sexually as STI's can cause infertility in both men and women
Also, bacterial infections like Syphilis, but Lyme Disease caused mine until it was treated then I got pregnant without even trying after 8 years of infertility. So check for it with a LLMD.
The only proven effective ways of becomming infertile for a man or woman involve surgery, referred to as a vasectomy for men or a tubal ligation for women.
