Why This Test Is Done
Doctors may order this test if you’re experiencing difficulty conceiving, have unexplained infertility, or are investigating potential sperm-related issues. It helps determine whether sperm are capable of moving efficiently, which is crucial for fertilization.
What to Expect Before the Test
No special preparation is needed. You’ll provide a semen sample (ejaculate) in a sterile container, typically collected by masturbation in a clinic or at home with instructions. Avoid ejaculation for 2–3 days before testing to ensure a representative sample.
What Happens During the Test
The sample is analyzed under a microscope to evaluate sperm movement patterns, including speed, direction, and consistency. The test focuses on motility (movement) rather than individual sperm count or shape.
What the Results Mean
Results are qualitative (descriptive) rather than numerical. A normal result indicates healthy, motile sperm, while poor motility may suggest underlying issues like oxidative stress, hormonal imbalances, or genetic factors that could affect fertility.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance
