Sperm Concentration (Total Sperm Count)

Why This Test Is Done

A sperm count test is often recommended if you or your partner are struggling to conceive. It may also be part of a broader evaluation for unexplained infertility, low testosterone, or conditions affecting reproductive health. Doctors may also order this test before certain surgeries or treatments that could impact fertility.

What to Expect Before the Test

You’ll need to provide a semen sample, typically collected through masturbation into a sterile container. Avoid ejaculation for 2–3 days before testing to get an accurate count. Wear loose clothing and follow any specific instructions your healthcare provider gives you, such as avoiding certain medications or substances that might affect results.

What Happens During the Test

The sample is analyzed under a microscope to count the total number of sperm cells. The test may also check for sperm motility (movement) and morphology (shape) in addition to concentration. Results are usually available within a few days.

Interpreting Your Results

While there are general reference ranges (typically considered low if below 15 million sperm per milliliter), results can vary based on individual health, age, and medical conditions. Your doctor will discuss your specific results in the context of your overall health and fertility history.
