In the subsequent 6 yr, these results have been verified by many groups around the world who had the necessary equipment and training to run successful ICSI programs. Martin RH. But still in future, we can conduct various research studies to find out the major causes of male infertility and can work in that direction to reduce such factors which can affect the future fertility of males. First, there are concerns regarding the suitability of the control subjects, who were of a different socioeconomic statusfrom the subjects having ICSI.

Infertility is often thought of as a problem only among women; men are often overlooked. According to the American Society for Reproductive Medicine, infertility is when couples cannot become pregnant after 1 year of trying. To be fertile, men must have enough sperm in their semen, and these sperm must be healthy. Sperm production is driven by hormones. In the brain, the pituitary gland makes 2 important hormones: luteinizing hormone LH and follicle-stimulating hormone FSH. Both of these hormones affect the testicle, an important organ for fertility. Sperm is produced in the testicle and travels through very small ducts the epididymis and vas deferens before it is released in semen. Some men have low amounts of sperm, or no sperm, in their semen. This can be caused by either a blockage of sperm delivery or problems with sperm production.
