Male Infertility

Male infertility is generally the result of an inability to properly produce healthy sperm or because of a blockage that prevents sperm from joining the semen. 

For a man to be fertile, the testicles must produce enough healthy sperm, he must be able to deliver an adequate quantity of normal sperm to a woman's vagina, and sperm must be able to fertilize the egg. Conditions that interfere with this process can make a man less fertile.
