Sperm Motility and Morphology Analysis (Quantitative and Qualitative)

Why This Test Matters for Fertility

Sperm motility and morphology are key indicators of sperm health. Healthy sperm should move efficiently and have a typical shape, which is essential for penetrating and fertilizing an egg. Abnormal motility or morphology may suggest underlying conditions affecting fertility, such as low sperm count, poor sperm quality, or genetic factors.

How the Test Works

This test involves analyzing a semen sample under a microscope. Motility is assessed by observing how well sperm swim (their movement speed and direction). Morphology is evaluated by checking the shape and structure of individual sperm cells. Some labs may use automated systems to count and classify sperm characteristics.

Sample Collection and Preparation

You will provide a semen sample, typically collected through masturbation after abstaining from sexual activity for 2–5 days. The sample is then examined in a lab to measure motility (percentage of motile sperm) and morphology (proportion of sperm with normal shapes). Fresh or preserved samples may be used depending on lab protocols.

Interpreting Results

Results are often reported as percentages or classifications (e.g., normal vs. abnormal motility/morphology). While specific reference ranges vary by lab, low motility (fewer than 40% moving sperm) or high percentages of abnormal shapes (e.g., more than 4% with severe defects) may raise concerns about fertility.
