What This Test Measures
Your semen sample is analyzed for volume (amount of fluid) and sperm concentration (number of sperm cells per milliliter). Advanced methods like electrophoresis may also assess sperm motility patterns or structural integrity.
Why It’s Done
This test is typically ordered as part of a fertility evaluation, especially for couples struggling with conception. It helps doctors identify potential issues like low sperm count, poor motility, or abnormal sperm shape that might affect fertility.
Preparation for the Test
No special preparation is needed. You’ll provide a fresh semen sample collected at the lab or at home (if instructed). Avoid ejaculation for 2–5 days before testing for the most accurate results.
What to Expect During the Test
A healthcare provider will collect your semen sample, which is then processed in the lab. Results are usually ready within 1–3 days, including detailed analysis if electrophoresis is used.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
Low semen volume or sperm concentration may indicate underlying health issues like hormonal imbalances, infections, or genetic factors. Abnormal findings can guide treatment options, such as medications, lifestyle changes, or assisted reproductive technologies.
A low semen volume or sperm count may suggest fertility challenges, but it doesn’t always mean you can’t conceive. Common causes include age, lifestyle factors, or medical conditions. Discuss your results with your healthcare provider to explore next steps.
Yes, if electrophoresis is used, it may provide additional insights into sperm motility patterns or structural abnormalities that standard counts might miss. Your lab report will clarify which specific tests were performed.
