Infertility; The male factor

Unlike the female sex that has a very complicated reproductive system, the male system is less complicated and the most causes of male infertility can be traced to sperm disorders. Several million sperm cells is are released in the male ejaculate (semen) during sexual intercourse. However, out these millions deposited into the vagina, only a few hundreds will finally make the journey to the female egg and have a chance of fertilizing it. The number of sperms that make this all-important journey determines to a large extent, a man's chances of getting his partner pregnant. This is because, the more sperm cells that get to the egg, the better the chances of a successful fertilization.
