Why This Test Matters

Sperm motility is a key factor in male fertility. Healthy sperm should move efficiently to reach and fertilize an egg. This test helps doctors determine if sperm movement is normal or if there may be underlying issues affecting fertility.

How the Test Works

A small sample of semen is collected and examined under a microscope. A specialized device measures the speed and direction of sperm movement. The results are often reported as a percentage of sperm that are motile (moving).

What to Expect Before the Test

You may be asked to abstain from ejaculation for 2–5 days before the test to ensure a sample with typical sperm motility. Wear comfortable clothing and bring any medications or supplements you take regularly.

What the Results Mean

Results typically focus on the percentage of sperm that are motile (e.g., 40% or higher is often considered normal, though ranges can vary). Low motility may indicate issues like low sperm count, genetic factors, or exposure to toxins.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Low sperm motility is a common cause of infertility and may require further evaluation, such as additional tests for sperm count, shape, or genetic testing. It can also be influenced by lifestyle factors like smoking, alcohol use, or exposure to environmental toxins.

Frequently asked questions

What causes abnormal sperm motility?
Abnormal sperm motility can result from genetic conditions, infections, hormonal imbalances, exposure to toxins, or lifestyle factors like smoking, excessive alcohol, or poor diet. Some medications or medical treatments may also affect motility.
Can lifestyle changes improve sperm motility?
Yes, certain lifestyle changes may support healthy sperm motility, such as avoiding smoking and excessive alcohol, maintaining a balanced diet rich in fruits and vegetables, managing stress, and ensuring adequate sleep. Avoiding exposure to heat (e.g., tight underwear) and certain chemicals may also help.
Is this test painful or uncomfortable?
No, this test is not painful. You may experience mild discomfort during semen collection, but the rest of the process involves a simple microscopic examination. If you have concerns, discuss them with your healthcare provider.
