You got your semen analysis report back. Now you are staring at a page full of numbers, abbreviations, and units that mean nothing to you on their own. Most men walk out of the clinic with that report in hand and no real explanation attached. That gap matters because what is printed on that page can tell you a lot about your fertility health, and understanding it gives you something to actually work with.
A semen analysis does not just count sperm. It looks at volume, movement, shape, acidity, and a few other things at once. Each measurement reflects a different part of how sperm are produced, stored, and delivered. One number being off does not automatically mean infertility. But it does mean something worth understanding properly.
Here is what each section of the report is actually measuring.
Semen Volume
This is the total amount of fluid produced in a single ejaculate. The World Health Organisation (WHO) 2021 reference values set the lower limit at 1.4 millilitres (1). A consistently low volume can point to issues with the seminal vesicles or prostate, or may suggest retrograde ejaculation, where semen travels back into the bladder rather than forward and out.
Sperm Concentration
In the semen analysis report, sperm concentration is the number of sperm per millilitre of semen. The WHO 2021 lower reference limit is 16 million sperm per millilitre (1). A count below that threshold is called oligospermia, which simply means fewer sperm than is considered typical. A complete absence of sperm in the ejaculate is called azoospermia, and it requires further investigation to work out whether the cause is a production problem or a blockage somewhere along the reproductive tract.
Total Sperm Count
Concentration and total count are not the same thing. Total count is the number of sperm across the entire ejaculate. The WHO 2021 guideline puts the lower reference limit at 39 million sperm per ejaculate (1). You could have a reasonable concentration per millilitre, but if semen volume is low, your total count can still fall short of that range.
Motility
Sperm need to move to reach and fertilise an egg. Motility refers to the percentage of sperm that are actually moving, but not all movement counts the same way.
Total motility includes any sperm that shows movement. Progressive motility refers specifically to sperm moving forward in a straight or nearly straight line. That second number is more meaningful because directional forward movement is what gets sperm where they need to go. The WHO 2021 reference values set the lower limit for progressive motility at 30%, and total motility at 42% (1).
Low motility is called asthenospermia. A 2017 study found that progressive motility was among the stronger predictors of natural conception in couples undergoing fertility evaluation (2).
Morphology
Sperm have a specific design: an oval head, a midpiece, and a tail. Morphology measures the percentage of sperm that actually conform to that structure. Deviations from normal shape reduce the likelihood of successful fertilisation.
The semen analysis reports typically use what is called Kruger's strict criteria, in which even minor defects are counted as abnormal. Under this system, the WHO 2021 reference limit is 4% normal forms, meaning that at least 4 in every 100 sperm must have the correct shape to fall within the reference range (1). That percentage sounds low, and it is, but it reflects just how variable human sperm morphology naturally is. When morphology falls below 4%, the condition is called teratozoospermia. It does not make conception impossible, but it does affect the odds.
pH Level
In the semen analysis report, pH level typically reflects the semen's acidity or alkalinity. The WHO 2021 guideline puts the normal pH at 7.2 or above (1). A very low pH can signal a blockage in the ejaculatory ducts or dysfunction in the seminal vesicles. A very high reading may point toward an infection.
White Blood Cell Count
A small number of white blood cells (WBCs) in semen is expected. When that count exceeds 1 million per millilitre, the condition is called leukocytospermia. Research has linked elevated WBC levels in semen with increased oxidative stress on sperm, which can affect both motility and DNA integrity (3).
What a Standard Semen Analysis Report Does Not Show You
Here is what catches many people off guard. A standard semen analysis report does not assess sperm DNA. Sperm can look perfectly normal under a microscope, move well, and still carry damage inside their genetic material. This damage is called sperm DNA fragmentation, referring to breaks in the genetic code carried by sperm cells.
A study published in Human Reproduction Update found that high sperm DNA fragmentation is associated with lower fertilisation rates, higher rates of miscarriage, and poorer outcomes in assisted reproduction (4). If your standard results come back normal but you are dealing with unexplained infertility or recurrent pregnancy loss, asking about a DNA fragmentation test is a reasonable next step.
Semen Analysis Results Can Vary
The same person can get different results on different days. Fever, stress, alcohol, illness, and the length of abstinence before collection can all shift the numbers. The WHO recommends abstaining from ejaculation for two to seven days before sample collection to get a more reliable result (1). Most clinicians suggest testing at least twice before drawing conclusions from any single result.

FAQs
Can a normal semen analysis guarantee fertility?
Not entirely. Normal results mean your measurable parameters fall within reference ranges, but a standard test does not assess issues like sperm DNA fragmentation, which can affect conception and pregnancy outcomes even when everything else looks fine.
How long does it take for semen parameters to improve after lifestyle changes?
Sperm takes around 74 days to fully mature, so changes from adjustments like reducing alcohol, improving diet, or addressing an underlying health condition typically show up in results about two to three months later.
