What Is Sperm Motility?

Sperm motility refers to how actively and efficiently sperm cells swim through semen. Healthy sperm should move quickly and in a straight path. This test checks the percentage and speed of sperm that are moving properly.

Why Is Sperm Motility Important?

Proper sperm motility is essential for sperm to reach and penetrate an egg. If sperm are not moving well, they may struggle to fertilize an egg, which can affect fertility.

How Is This Test Performed?

A semen sample is collected, typically through masturbation after 2–5 days of abstinence. The sample is then examined under a microscope to assess the percentage of sperm that are motile (moving) versus non-motile (stuck or not moving).

What Does the Test Result Mean?

Results are reported as a percentage of sperm that are moving (e.g., 40% motile sperm). While specific reference ranges vary by lab, lower motility percentages may raise concerns about fertility, though other factors (like sperm count or shape) also play a role.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What causes sperm motility issues?
Sperm motility problems can arise from lifestyle factors (e.g., smoking, excessive alcohol), medical conditions (e.g., hormonal imbalances, infections), or genetic factors. Sometimes, no clear cause is identified.
How can I improve sperm motility?
Lifestyle changes like quitting smoking, maintaining a healthy weight, reducing alcohol intake, and managing stress may support sperm health. Certain nutrients (e.g., zinc, vitamin C) and avoiding heat exposure (e.g., tight underwear) may also help.
Is sperm motility testing painful or uncomfortable?
The test itself is not painful, but collecting a semen sample may feel uncomfortable or require abstinence for a few days beforehand. Most people find the process straightforward.
