You Got Your Semen Analysis. Now What?
Your semen analysis isn't a pass/fail test. Here's what the numbers actually mean.
A semen analysis is one of the most useful starting points in understanding male fertility health. It is also one of the most misunderstood. It is not a pass/fail test, and it does not on its own predict whether you can or cannot conceive.
The main measurements
- Volume — how much fluid was in the sample.
- Concentration — how many sperm are in each milliliter.
- Total sperm count — concentration multiplied by volume.
- Motility — the percentage of sperm that are moving, and how well.
- Morphology — the percentage of sperm with a typical shape, using very strict criteria.
What the reference ranges mean
Labs often compare results with reference values from the World Health Organization. These values describe results seen in men whose partners conceived within a year. They are not cutoffs for fertile versus infertile. Many men below a reference value conceive, and some men above them have difficulty.
A single number below a reference range is a reason to look closer, not a diagnosis.
Why one test isn't the full story
Semen results naturally vary from sample to sample. Recent illness or fever, abstinence time, sample collection, and transport can all affect results. That is why clinicians often repeat a test before drawing conclusions.
What else matters
Semen analysis measures sperm, not your whole reproductive health. Hormones, medications, medical history, lifestyle, and sexual health can all influence fertility and may be worth reviewing alongside your results.
Reasonable next steps
- Review your results with a qualified clinician rather than interpreting them alone.
- Ask whether a repeat test is appropriate.
- Ask whether hormone testing or a physical exam may help.
- Look at lifestyle factors you can influence, like heat exposure, smoking, and sleep.
