Men's sperm counts have dropped by more than 50% over the past five decades, according to a 2022 meta-analysis in Human Reproduction Update. The decline is global and appears to be accelerating. Yet male fertility barely comes up unless a couple is already struggling to conceive - and even then, it's often the woman who gets investigated first. That's a problem, because the World Health Organisation (WHO) puts infertility at roughly one in six people worldwide, with men accounting for a significant share of those cases.
What is male fertility?
Male fertility is a man's capacity to get a female partner pregnant without medical help. That requires enough sperm being produced, those sperm moving forward effectively, and being the right shape to reach and fertilise an egg.
A standard semen analysis looks at sperm count (how many), motility (how well they swim), morphology (their shape), and semen volume. A normal sperm concentration falls between 15 and 259 million sperm per millilitre of semen, and at least 40% should be moving efficiently. When several of these markers fall short together, natural conception becomes harder.
Why is male fertility health important?
Two reasons, and one of them rarely comes up.
The obvious one: conception takes two people, and fertility problems are just as likely to be male as female. StatPearls, published by the National Institutes of Health (NIH), puts it plainly: men are the sole cause of infertility in about 20% of cases and a contributing factor in another 30 to 40%. Investigating only the woman in a couple that can't conceive is, statistically, a coin flip at best.
The less obvious reason has to do with overall health. A 2022 meta-analysis in Human Reproduction Update found that global sperm counts have fallen by more than 50% over the past five decades, and the decline appears to be speeding up. The same period saw rises in testicular cancer rates and hormonal disruption in men. Sperm health may reflect what's happening in the male body more broadly, well beyond reproduction.
Is male infertility permanent?
Usually not, and this is where things get more hopeful than most people expect.
According to StatPearls (NIH, updated February 2024), treatable and reversible causes account for about 18% of male infertility cases. These include hormonal imbalances, varicocele (a swelling of veins in the scrotum that can overheat sperm), infections, and the effects of certain medications or substances.
In a further 70% of cases, while the underlying issue may not be fully correctable, assisted reproductive technology (ART) such as IVF (in vitro fertilisation) or ICSI (intracytoplasmic sperm injection) can still make pregnancy possible. Only around 12% of cases fall into the category of untreatable sterility.
Everyday lifestyle factors also have a measurable effect. Smoking, heavy alcohol consumption, obesity, and regular heat exposure around the testes can all drag sperm quality down. Since sperm take around 72 to 90 days to develop, positive changes in habits can start showing up in test results within a few months.
Can male infertility be cured?
For many men, yes. Or at least meaningfully improved.
Treatment options depend heavily on the cause. Hormonal therapy works well where the issue is hormonal. Surgery can address physical blockages or restore the reproductive tract after a vasectomy. Where sperm production itself is the problem, ART gives couples another route to biological parenthood.
Cases involving primary testicular failure or certain genetic conditions generally don't respond to treatment. However, they're the minority. Most men who actually look into it do find options available to them.
Can supplements improve male fertility?
Yes. When it comes to male fertility supplements, there is rarely a single nutrient that changes everything on its own. Sperm production is a complex biological process that depends on multiple pathways working together, including hormone regulation, energy production, DNA protection, and defense against oxidative stress. Because of this, researchers have increasingly focused on the benefits of combining several fertility-supporting nutrients rather than relying on a single vitamin or mineral.
A 2025 meta analysis found that men who took combinations of three or more fertility supplements experienced greater improvements in sperm concentration than those taking individual nutrients alone. The findings suggest that certain vitamins, minerals, antioxidants, and amino acids may work synergistically, supporting different aspects of sperm development at the same time. Rather than simply adding their effects together, these nutrients may enhance each other's activity, leading to more meaningful improvements in overall sperm health.
Common fertility supplements often include ingredients such as zinc, selenium, coenzyme Q10, folate, vitamins C and E, L-carnitine, and other antioxidants. These nutrients are thought to help reduce oxidative stress, support healthy sperm formation, improve cellular energy production, and protect sperm DNA from damage. Since sperm take around 74 days to develop, any nutritional intervention generally requires at least two to three months before measurable changes are seen.
Sapyen's Male Fertility Supplement, RESET90, has been specifically formulated to support male reproductive health over a 90 day period, aligning with the natural sperm production cycle. The formulation combines key vitamins and nutrients selected to help optimise fertility health and support healthy sperm development.
While supplements can play an important role in a fertility improvement plan, they are most effective when combined with healthy lifestyle habits such as regular exercise, adequate sleep, a balanced diet, stress management, and avoiding smoking. Before starting any new supplement regimen, it is advisable to speak with a general practitioner or healthcare professional, particularly if you take prescription medications or have existing medical conditions.
How to check male fertility
Fertility isn't a women's issue. It never was. Knowing where you stand is the right step. Clinically, the starting point is a semen analysis: a lab assessment of sperm count, motility, morphology, and volume. Doctors generally recommend it after 12 months of trying to conceive without success, or 6 months if there's a known risk factor.
At-home testing has become a reasonable first step for men who want an early read without a clinic visit.
The Sapyen At-Home Male Fertility Analysis Kit lets you check your sperm health privately, from home, before deciding whether to book in with a general physician or fertility specialist. For men who've been sitting on that first step, that alone can make the difference.

FAQs
Can male fertility improve naturally?
Yes. Sperm are continuously produced, with a full development cycle taking around 74 days. Improvements in diet, exercise, sleep, stress management, and smoking cessation can lead to measurable changes in sperm quality within two to three months.
When should a man get a fertility test?
Men should consider fertility testing if they have been trying to conceive for 6 to 12 months without success, have a history of fertility-related conditions, or simply want to understand their reproductive health before starting a family.
