A man’s fertility or male fertility generally relies on the quantity and quality of his sperm count. If the number of sperms a man ejaculates is low in count/sperm count or if the sperm is of a poor quality or quantity, it will be difficult for men, and sometimes impossible for men, for him to cause a pregnancy.
There are widespread causes of male infertility that are found in 40% couples. For about one in five infertile couples, the infertility problem lies simply in the male partner.
It is estimated that one in twenty men has some kind of infertility problem for one or more reasons with low numbers of sperm count in his ejaculation. However, only about one in every 100 men has no sperm in his ejaculation.

The male reproductive system
The pituitary gland and the hypothalamus part is located at the base of the brain that controls the production of male hormones and sperm. The testes are a pair of egg-shaped glands that sit in the scrotum down to the base of the penis. The testes generally make sperm and the male sex hormone testosterone.
The uterus is a female reproductive organ and is responsible for different reproductive functions such as implantation, menses, gestation, labor and delivery. It is located in the pelvic area between the bladder and the rectum. It is also receptive to hormonal changes within the female body thus allowing adaption to different stages of reproductive cycle.
