Why This Test Matters in Fertility Evaluation

Sperm motility is a critical factor in male fertility. Motile sperm must move efficiently to reach and fertilize an egg. This test helps doctors determine whether sperm are capable of this movement, which is essential for conception.

How the Test Works

You’ll collect semen in a sterile container over a 24-hour period. The sample is then examined under a microscope to evaluate the percentage of sperm with normal forward progression. This is often part of a broader fertility assessment.

What to Expect Before the Test

Avoid ejaculation for 2–3 days before testing to ensure a representative sample. Wear loose clothing and use a clean, dry container provided by your healthcare provider. Follow any specific instructions they give you.

What the Results Mean

Results typically report the percentage of motile sperm (e.g., 0%–100%) and the percentage of sperm with normal tail movement. Lower motility may indicate underlying issues like poor sperm production, damage, or hormonal imbalances.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Low sperm motility can signal fertility problems, but it may also be influenced by lifestyle factors (e.g., smoking, heat exposure) or medical conditions (e.g., varicocele, infections). This test helps guide further evaluation, such as hormone testing or genetic assessment, if needed.
