What Does This Test Measure?
The test measures sperm motility, which includes two key aspects: **sperm movement speed** and **sperm movement direction**. Healthy sperm should move quickly and swim in a straight path toward an egg. The test may also assess overall sperm concentration and morphology (shape) indirectly through semen analysis.
Why Might You Need This Test?
This test is often recommended if you or your partner have trouble getting pregnant, unexplained infertility, recurrent miscarriages, or if you’ve had repeated failed IVF cycles. It can also be part of a general fertility evaluation.
How Is the Test Performed?
A semen sample is collected through masturbation in a sterile container. The sample is then analyzed under a microscope to evaluate how many sperm are moving, their speed, and their direction. This process typically takes about 1–2 hours.
What Are the Results Used For?
Results help doctors understand whether sperm motility is a contributing factor to infertility. Low motility or abnormal movement patterns may suggest issues like blockages, hormonal imbalances, or other underlying conditions that need further investigation.
