Also written as sperm test

Written by Zayn Miah & R KhanomLast updated 17 September 2026Not clinically reviewed

A laboratory test that measures sperm count, movement (motility) and shape (morphology) in a semen sample.

In plain English

It's the standard lab test on a semen sample, looking at how many sperm there are, how well they move, and how normally they're shaped.

Why it matters

It's usually one of the first tests done in a fertility work-up and shapes whether treatment routes like ICSI are recommended.
