What do my semen analysis results mean?
Results are read against WHO reference ranges for concentration, motility and morphology. One result below range is common and usually needs a repeat test, not a diagnosis.

How this tool works
Why one result below range is not a diagnosis
A semen analysis reports volume, concentration, motility and morphology against WHO lower reference limits. Results vary a lot between samples from the same person.
Enter your figures and the guide shows each against its reference limit, explains what a low value can and cannot mean, and sets a repeat-test date.

What a semen analysis reports, and what it does not settle
The context this tool records alongside a result. Sample conditions change the numbers, which is why one analysis is not treated as a conclusion.
| What the report or context covers | Why it changes interpretation |
|---|---|
| Abstinence period (2 to 7 days) | Outside that range, volume and concentration shift and the sample may not be comparable |
| Complete sample collected | Losing the first part of the ejaculate can falsely lower the concentration |
| Collection method | Laboratory-approved collection differs from other methods |
| Time from collection to analysis | Motility falls with delay, so a home-collected sample needs rapid transport |
| Recent illness or fever | Can lower quality for up to several months afterwards |
| Reason for the test | An initial fertility analysis, a repeat, and a post-vasectomy check are read against different questions |
| Laboratory and reference interval | Thresholds and methods differ; compare against the interval printed on that report |
| Number of samples | At least two analyses, around six weeks apart, are needed before drawing a conclusion |
A result below a reference interval is not a diagnosis of infertility, and a result within it does not confirm fertility. Sudden or severe testicular pain, sudden scrotal swelling, or a new lump or persistent change in shape needs assessment on its own terms and not through this tool.

A useful answer before more reading
Interpret the report in context without assigning a pass or fail
The tool separates immediate symptoms, collection quality, complete laboratory findings and repeat-testing context, then produces a summary that can be taken to a GP, fertility clinician or treating service.
Use the whole report
A semen analysis is a clinical data point, not a fertility verdict
Semen analysis describes the sample collected on one day. Collection conditions, recent illness, medicines, laboratory methods and normal biological variation can change the result. The most useful interpretation keeps the original report, the laboratory comment and the collection history together.
Start with collection quality
Record the abstinence interval, whether the complete sample reached the container, the collection method, any lubricant or collection product, transport time and temperature, and whether the laboratory received the sample within its instructions. The tool allows an exact interval and exact times when these are known, while preserving the broader laboratory categories when they are not.
Read parameters together
Volume, concentration, total sperm number, motility, vitality and morphology describe different parts of the sample. One isolated result cannot establish whether conception will or will not occur. A result within a reference interval does not guarantee pregnancy, and a result outside an interval does not identify the cause of infertility.
Keep the clinical assessment broader than the sample
Australian male infertility guidance places semen analysis alongside reproductive and medical history, physical examination and, where relevant, parallel assessment of both partners. A new lump, persistent swelling or shape change needs examination even when the semen report looks reassuring.
What the main result pathways mean
Collection concern
A lost first portion, an unclear abstinence interval, delayed processing, temperature uncertainty or an unapproved product may make a repeat under standard conditions more useful.
Flagged first report
An unexpected initial result is normally reviewed in context and may be repeated. The tool does not convert the laboratory flags into a pass or fail score.
Flagged repeat report
Persistent findings support a fuller male fertility assessment, including history, examination and targeted investigations selected by the treating clinician.
No sperm reported
Azoospermia or “no sperm seen” needs confirmation and specialist assessment. The report alone cannot identify whether the cause relates to production, obstruction, collection or another factor.

Frequently asked questions
- What is a normal sperm count?
- 16 million per mL or more, by WHO 2021 reference limits. Concentration is only one of several measures.
- My motility is low. Can I improve it?
- Sometimes: stopping smoking, reducing alcohol, avoiding heat and treating infections all help over three months.
- How accurate is one test?
- Not very. Results vary between samples, which is why a repeat is standard before any decision.
- What does morphology 3% mean?
- Just below the 4% reference. On its own it rarely prevents conception; view it with the other values.
