You've probably never given much thought to your male fertility testing until the moment it actually matters. And then, suddenly, it matters enormously. A year of trying without success. A partner's growing anxiety. The quiet, creeping question neither of you wants to ask out loud: could the issue be with me?
The research has an answer most men do not expect. Male factors contribute to roughly 50% of all infertility cases in couples [1]. Not a fringe scenario. Not a small percentage. Half. Yet the conversation around fertility almost always gets directed at women first. Men wait. Men get left out of early testing. That delay costs time that, in fertility, is genuinely hard to make up for.
This article is for men who want to understand where they stand and why getting tested sooner tends to lead to better outcomes, regardless of the result.
What Does Fertility Testing Actually Involve for Men?
Male fertility testing starts with a semen analysis (SA). It is the first and most important diagnostic test used to assess a man's reproductive health [2]. According to the World Health Organization's (WHO) 6th Edition Laboratory Manual, published in 2021, a semen analysis looks at several things: how much fluid is produced per ejaculate, the concentration of sperm within it, total sperm numbers, how many are actively moving (motility), and what percentage look structurally normal under a microscope (morphology) [3].
What a standard semen analysis does not capture is whether the genetic material inside each sperm is actually intact. That requires a separate assessment called sperm DNA fragmentation (SDF) testing, which the 2021 WHO manual now formally recognises as part of male fertility evaluation [4]. A semen analysis can tell you how many sperm are present. The DNA fragmentation test tells you how many of them are carrying undamaged instructions to the egg.
Hormone blood tests, scrotal ultrasound, and genetic testing are used in cases where the initial semen analysis finds something worth investigating further. But the SA is where every male fertility evaluation begins.
When Should a Man Undergo Male Fertility Testing?
The 2024 updated Male Infertility Guideline from the American Urological Association (AUA) and the American Society for Reproductive Medicine (ASRM), the most current clinical guidance in this field, recommends that when a couple has difficulty conceiving, both partners should be assessed at the same time, right from the beginning. Not one after the other [5]. Waiting to fully evaluate a female partner before evaluating the male is no longer considered good clinical practice.
As a general rule, male evaluation is recommended after 12 months of unprotected intercourse without achieving pregnancy. That window shortens to 6 months when the female partner is 35 years of age or older [5].
But the 12-month mark is not a fixed barrier for every man. The same guidelines are clear that men with known risk factors should not wait. Those risk factors include:
- a history of undescended testicles (medically termed cryptorchidism)
- prior surgery on the groin or testicles
- a varicocele (enlarged veins within the scrotum that can raise scrotal temperature and affect sperm production)
- a previous sexually transmitted infection
- cancer treatment involving chemotherapy or radiation
- a known genetic condition that could affect sperm production
The guidelines also state that evaluation of the male partner should be considered when a couple has experienced two or more pregnancy losses, regardless of whether previous conceptions were achieved without difficulty [5]. Recurrent pregnancy loss is not exclusively a female factor issue, and treating it that way means potentially missing half of the picture.
Why the Waiting Culture Around Male Fertility Is a Problem
A 2023 research study found that men with male factor infertility experience higher rates of depression and anxiety, and lower self-esteem, compared to the general population [6]. Much of that tracks back to the silence around male fertility and the widespread assumption that if there is a problem, it sits on the female side of the equation.
The data does not support that assumption. A 2024 update, drawing on multiple large-scale population studies, confirms that male factors are solely responsible for around 20% of infertility cases, and a contributing factor in another 30% to 40%, meaning male biology meaningfully shapes roughly half of all cases where a couple cannot conceive [1].
Male fertility testing removes the uncertainty. It either finds something that can be addressed or confirms that everything looks normal. Both outcomes are useful for information.
The Broader Trend in Sperm Quality
A 2022 review study, drawing on data from 53 countries over five decades, found that average sperm counts have declined significantly, with the rate of decline accelerating after the year 2000 [7]. This trend, initially documented in men from North America, Europe, and Australia, was confirmed in the update to be present across South America, Asia, and Africa as well.
Nobody fully understands why. Environmental exposures, lifestyle factors, and diet have all been studied. What is clear is that population-level trends do not predict any individual man's results, but they do make a stronger case for not assuming everything is fine without actually checking.
What Happens After Male Fertility Testing?
If a semen analysis returns results within normal ranges, that is genuinely reassuring information. If it finds something outside normal ranges, the 2024 AUA and ASRM guidelines state that even a single abnormal result should prompt referral to a specialist in male reproductive health, who will conduct a thorough history, physical examination, and any additional testing warranted by the findings [5].
That next tier of male fertility testing might involve blood tests for hormones such as follicle stimulating hormone (FSH) and testosterone, a scrotal ultrasound, genetic analyses including a sperm DNA fragmentation assessment [5].
Many causes of male infertility are treatable once identified. A varicocele can be surgically corrected. Hormonal imbalances can be managed medically. Infections affecting the reproductive tract respond to treatment. None of that is available without first knowing what is actually going on. The 2021 WHO semen manual is explicit that semen analysis also guides the choice between different assisted reproductive options and monitors how a man responds to treatment at each stage of a fertility plan [3].
Is There a Reason Not to Get Tested Early?
Some men worry about what they might find. That is understandable. But the cost of knowing is low compared to spending 12 months trying to conceive when there is a correctable issue that could have been addressed far earlier.
If you and your partner are trying to conceive, or planning to in the next year or two, proactive testing puts you ahead of the problem rather than behind it. If you are not yet at that point but want a baseline picture of your own reproductive health, a semen analysis is a simple, non-invasive way to get one.

FAQs
Can a man have normal semen analysis results and still face fertility difficulties?
Yes. A semen analysis measures sperm count, motility, and morphology, but it does not assess sperm DNA integrity. A man can have results that look normal on every standard parameter and still have elevated sperm DNA fragmentation, which can affect the ability to fertilise an egg and carries implications for early pregnancy outcomes.
Does male fertility decline with age the same way female fertility does?
The decline is more gradual in men, but it is real. Sperm DNA fragmentation tends to increase with age, and conception rates do fall over time in older men, even when semen analysis parameters appear within normal limits.
