Sperm Count and Motility Analysis (Semen Analysis)

What Is a Sperm Analysis Used For?

A sperm analysis measures two key factors: sperm concentration (how many sperm are present) and sperm motility (how well they move). These results help doctors determine if sperm are healthy enough to fertilize an egg. It may also detect conditions like low sperm count, poor movement, or abnormal sperm shapes that could affect fertility.

How Is the Test Performed?

You’ll provide a semen sample (usually collected through masturbation into a sterile container) after abstaining from ejaculation for 2–5 days. The sample is then examined under a microscope to count sperm and assess their movement. Some labs may also check for sperm shape or other characteristics.

Preparation and Timing

To get accurate results, avoid ejaculation for 2–5 days before testing. Wear loose underwear and use a clean container provided by your lab. Follow any specific instructions your healthcare provider gives you.

When Might This Test Be Needed?

A sperm analysis is often recommended if you or your partner have trouble getting pregnant, unexplained infertility, recurrent miscarriages, or if you’ve had previous fertility treatments. It may also be part of a general reproductive health evaluation.
