Male Infertility: Semen Analysis, Causes and Treatment Options

Male factor contributes to roughly half of all infertility cases, yet in a large number of couples the man is tested only after months of investigating the woman. That sequencing costs time that matters.

Here is the short answer: a semen analysis is inexpensive, non-invasive, reports within a few days, and identifies or rules out male factor at the very start of a fertility workup. It should be done in parallel with the female evaluation, not after it.

What a Semen Analysis Measures

A semen analysis assesses several independent parameters. A result can be abnormal in one and perfectly normal in the others, which is why the full report matters more than any single number.

The World Health Organization published updated reference values in its 6th edition in 2021. These are lower reference limits, meaning the 5th percentile of men who achieved pregnancy within 12 months.

A crucial point about interpretation. These are not pass or fail thresholds. A man below a reference limit can conceive, and a man above every limit can still have difficulty. The values describe populations, not individuals, and your doctor reads them alongside the female partner's findings and your history.

Why One Test Is Not Enough

Semen parameters fluctuate considerably in the same man from sample to sample. A fever, a recent illness, a period of stress, abstinence duration, or even the collection method can shift results meaningfully.

For this reason, an abnormal first result should always be repeated, usually after a gap of at least four weeks. Sperm take approximately 74 days to develop from start to maturity, so a repeat test around three months later also reflects any lifestyle changes made in between.

Acting on a single abnormal sample is one of the commonest errors in male fertility assessment.

How to Give an Accurate Sample

The reliability of the result depends substantially on how the sample is collected.

• Abstain from ejaculation for 2 to 7 days before the test. Shorter reduces volume and count, longer reduces motility
• Collect the sample by masturbation into a sterile container provided by the laboratory
• Do not use lubricants, saliva, or condoms, as all of these are toxic to sperm
• Collect the entire ejaculate, particularly the first portion, which contains the highest sperm concentration
• If collecting at home, keep the sample at body temperature and deliver it to the lab within 30 to 60 minutes
• Avoid testing within 2 to 3 weeks of a fever or significant illness

Common Causes of Male Infertility

Exogenous testosterone deserves specific mention. Testosterone supplementation, whether prescribed or taken for bodybuilding, suppresses the pituitary signals that drive sperm production and can reduce sperm count to zero. Many men taking it are entirely unaware of this. It is often reversible after stopping, but recovery can take six to twelve months or longer.

What the Terms on Your Report Mean

Azoospermia is further divided into obstructive, where production is normal but the sperm cannot get out, and non-obstructive, where production itself is impaired. The distinction is critical because obstructive azoospermia often has excellent outcomes with surgical sperm retrieval combined with ICSI.

Treatment Options for Male Infertility

Lifestyle correction. Stopping smoking, reducing alcohol, losing excess weight, stopping anabolic steroids or testosterone, and avoiding prolonged heat exposure. Because of the 74-day sperm cycle, improvements take around three months to appear on testing.

Treating the underlying cause. Correcting thyroid dysfunction, treating elevated prolactin, treating infection with appropriate antibiotics.

Varicocele repair. In men with a clinically palpable varicocele and abnormal parameters, surgical repair improves semen parameters in a substantial proportion and can improve natural conception rates.

Medical therapy. Hormonal treatment where a specific hormonal deficiency is identified. Antioxidant supplementation has modest and inconsistent evidence, and should not replace evaluation.

Assisted reproduction. IUI for mild to moderate male factor with adequate total motile count. ICSI, where a single sperm is injected directly into an egg, for severe male factor. Surgical sperm retrieval combined with ICSI for azoospermia.
