A sperm count, commonly known as a semen analysis, determines the number and quality of a man's sperm and semen. The thick, white fluid discharged from a man's penis at his sexual climax is known as sperm (orgasm). Ejaculation is the term for this process. Sperm, the genetic material-carrying cells in a man's body, are found in sperm. When a sperm cell combines with an egg from a woman, an embryo (the earliest stage of the development of an unborn baby) is formed. It can be difficult for a guy to get a woman pregnant if he has a low sperm count or irregular sperm shape or movement. Infertility is the inability to conceive a child. Both men and women are susceptible to infertility. Male infertility is the cause of infertility in roughly one-third of couples who are unable to produce children. A sperm analysis can assist in determining the cause of male infertility.
