Semen analysis, also known as a sperm count test, analyzes the health and viability of a man’s sperm. Semen is the fluid containing sperm (plus other sugar and protein substances) that’s released during ejaculation.
A semen analysis is often recommended when couples are having problems getting pregnant. The test will help a doctor determine if a man is infertile. The analysis will also help determine if low sperm count or sperm dysfunction is the reason behind infertility.
A normal result for sperm shape is that more than 50 percent of sperm are normally shaped. If a man has greater than 50 percent of sperm that are abnormally shaped, this reduces his fertility.
