A sperm count or semen analysis test measures a man's sperm's general health and viability. Semen is the ejaculated organic fluid containing sperm cells. This test measures the amount of semen, its characteristics, the concentration of sperm in the semen, their motility and morphology.
This test is used to screen infertile couples. Semen analysis is used to determine the success of a vasectomy also.
