A sperm consists of the head, tail and mid-piece sections. To successfully fertilise an egg, the sperm will need to be able to move its tail (motility) to propel itself through cervical mucus to travel through the uterus and fallopian tube to reach the egg. It will also need to be normally shaped in order to penetrate the outer shell of the egg to deliver its genetic package contained in the head.
Male Infertility is due to low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Illness, injuries, chronic health problems, lifestyle choices and other factors can play a role in causing male infertility.

A lower than normal sperm count (fewer than 15 million sperm per milliliter of semen or a total sperm count of less than 39 million per ejaculate)
