What causes male infertility?
The causes of male infertility are an alagist to those of female infertility. The sperm are produced in the testicle and that testicle needs to have adequate hormonal stimulation to produce the sperm. Something may have happened to the testicle somewhere along the way. For example, men who are born with undescended testicles commonly have very low sperm production. Men who had mumps or kitis, where the mumps virus actually goes and infects the testicle, commonly have very low sperm counts. There can a blockage of the duct, such as happens intentionally doing a vasectomy, but can happen as a result of an infection in the male reproduction tract. That can cause lack of sperm in the ejaculate. Of course, if the man has a hormonal problem, which he's entitled to have just as women, he may not produce sperm from the testicle. You hope to find this last fertility category because, of course, it's easily treated by giving that man the hormonal stimulation that he needs. Those are the basic causes of male infertility. There's also the issue of heat being delivered to the testicle and something called a varicocele, where there are varicose veins on the outside of the testicle that can cause an increase in the temperature and decrease sperm production in that man.
