When a couple is struggling to conceive, the conversation tends to focus on the woman’s cycles, hormones, and egg quality. The male side of the picture is often either overlooked or reduced to a single test: a standard semen analysis that checks how many sperm there are, how fast they swim, and what they look like under a microscope. The problem? The routine semen analysis is an initial fertility test, but it has its limitations. It often doesn't provide the complete picture of whether the sperm can do their job and other important underlying issues. This is where doctors recommend the SpermEGT DNA methylation test.
Male Fertility Is Half the Story - But Often Poorly Tested
According to the World Health Organization (WHO), male factors contribute to around 50% of infertility cases globally [1]. Yet for most men, the investigation stops at a basic count, motility, and morphology check.
Here's what that misses:
15–40% of men are infertile despite having perfectly normal semen analyses, a normal medical history, and normal physical examinations - a condition now referred to as unexplained male infertility [2]In other words, if sperm appear to be normal under a microscope, it does not mean they are functioning properly at a molecular level. So where does the problem actually hide?
What Is DNA Methylation and Why Does It Matter for Sperm?
Think of your deoxyribonucleic acid (DNA) as a set of instructions. DNA methylation is a process that controls which of those instructions gets turned on or off. In sperm, this process is critical.
DNA methylation tells whether the sperm can find, bind to an egg, penetrate it, and support healthy embryo development after fertilisation.
When methylation patterns are disrupted, the sperm may look completely fine on paper, but fail at these core steps. A 2020 systematic review in Human Reproduction Update found that male subfertility and abnormal sperm function are associated with abnormal sperm DNA methylation patterns, even when standard parameters appear normal [3].
As per a study conducted by Scientific Reports in 2021, alterations in sperm DNA methylation contribute to 64% decline in male fertility as men grow older during in vitro fertilization [4]. To be precise, most of the reduction in male fertility is due to minor genetic modifications in sperm that cannot be detected through normal semen analysis.
What is the procedure for the SpermEGT DNA Methylation Test?
The SpermEGT DNA Methylation Test is designed as a simple home-to-lab process. A test kit is delivered to your home, where you collect a semen sample using the instructions and materials provided. The sample is then shipped back to certified and accredited laboratories using the prepaid packaging included in the kit. The sample remains stable for up to three days during transit. Once testing is completed, fertility specialists review the findings and provide an easy-to-understand report explaining the results.
What the SpermEGT Test Actually Measures
The SpermEGT Deoxyribonucleic Acid (DNA) Methylation Test, developed by Path Fertility and available through a partnership with Sapyen, is the first clinically validated home-to-lab sperm epigenetic assay available to the public. It analyses methylation patterns across more than 1,200 genes that are critical to sperm function.
Rather than just reporting how many sperm you have, this test asks a different set of questions:
Can your sperm find and bind to an egg?
Can they penetrate it?
Are their internal instructions properly set up to support embryo development?
Research published in Fertility and Sterility found a striking difference in pregnancy and live birth outcomes based on sperm DNA methylation profiles. Among couples undergoing intrauterine insemination (IUI), those with poor methylation profiles had a cumulative live birth rate of 19.4%, compared to 44.8% for couples with excellent methylation profiles - a gap that standard semen analysis alone would not have predicted [5].
Identifying the issue sooner would have helped identify the most appropriate fertility treatment pathway.
Who Should Consider This SpermEGT DNA Methylation Test?
You don't need to be in the middle of fertility treatment to find this test useful. It's worth thinking about if:
You've been trying to conceive for several months without success
Your standard semen analysis came back normal, but you’re still unable to conceive a baby
You've had failed intrauterine insemination (IUI) or in vitro fertilisation (IVF) cycles without a clear explanation
You want a clearer picture of your reproductive health before starting a family
The test is also relevant for men who are planning ahead, wanting to understand their fertility status while they still have time to address any issues.
How Epigenetic Testing Changes the Fertility Conversation
For a long time, male fertility testing had two speeds: basic (semen analysis) or invasive (surgical or genetic testing done at a clinic). There was not much in between.
Sperm DNA methylation testing fills that gap. It gives fertility specialists and the men themselves - a functional view of what sperm are capable of doing, not just what they look like. This aspect matters for treatment planning.
Knowing that sperm function is compromised at a methylation level can help guide decisions about IUI versus IVF, or whether additional investigation is needed.
As the Lancet noted in its 2020 review of male infertility, advanced diagnostic tests to investigate sperm quality and function have been developed specifically to improve diagnosis and management beyond what semen analysis can offer [1].
Why Choose Sapyen for the SpermEGT DNA Methylation Test
Sapyen's SpermEGT DNA Methylation Test combines a core semen analysis with the SpermQT epigenetic assay from Path Fertility — meaning you get both standard parameters and a deep look at how your sperm DNA is actually programmed, in a single kit you collect at home.
The semen sample is sent to a certified/accredited lab, and results are reviewed by trained specialists and benchmarked against WHO guidelines. The reports are written in plain language with no medical jargon
Sapyen's test is trusted by fertility specialists, urologists, and general practitioners who have noted the depth and accuracy of results it provides.
If you want the most complete picture of your sperm health — covering count, motility, morphology, DNA integrity, immune factors, and now epigenetic function — Sapyen's Complete Analysis brings all of that together in one convenient kit. It's worth considering for anyone who wants clear, actionable information before taking their next step, whether that's trying naturally, exploring IUI, or preparing for IVF.

FAQs
How much does the SpermEGT DNA Methylation Test cost?
The SpermEGT DNA Methylation Test is priced at around USD 529 through Sapyen, though pricing may vary by market. The package includes the home collection kit, semen analysis, methylation assay, and specialist-reviewed results.
Can you still get pregnant with abnormal SpermEGT methylation?
Yes. Abnormal methylation may lower fertility potential, but many couples still achieve pregnancy naturally or with lifestyle changes and fertility treatments.
