Sperm Head Morphology Analysis (Qualitative)

Why This Test Is Done

Doctors may order this test if you’re struggling to conceive, have unexplained infertility, or have a history of repeated miscarriages. It helps identify whether sperm shape or size issues are contributing to fertility challenges.

What to Expect Before the Test

You’ll likely provide a semen sample (usually via masturbation) into a sterile container. Avoid ejaculation for 2–3 days before testing to ensure a representative sample. Wear a condom if sexual activity is possible during this time.

What Happens During the Test

A lab technician will examine your semen under a microscope. They’ll count and classify sperm based on standard criteria (e.g., head shape, size, and surface defects). Results are qualitative, meaning they describe proportions of normal vs. abnormal sperm rather than exact numbers.

What the Results Mean

Results are reported as a percentage of sperm with normal morphology (typically 14% or higher is considered normal). Abnormalities may include irregular shapes (e.g., head defects, double heads, or misshapen tails). These findings don’t diagnose a specific cause but may guide further testing (e.g., hormone checks, genetic evaluation).
