The semen analysis says everything is normal. Count, motility, morphology - all fine. So why isn't conception happening? That's exactly the question that a routine semen analysis can't always answer. Did You Know? Approximately 25% of infertility cases involve men with completely normal semen parameters - meaning the actual problem goes undetected by standard testing [1]. The SpermEGT DNA Methylation test is a new and specialised test that has emerged over the last few years. It was developed specifically to look deeper into sperm quality, beyond what the microscope can see.
What Is the SpermEGT DNA Methylation Test?
Deoxyribonucleic acid (DNA) methylation is a natural biological process where small chemical tags attach to a cell's DNA. These tags act like switches; they control whether genes are turned on or off, without altering the actual genetic code.
In sperm, this methylation process governs whether the genes responsible for fertilisation, embryo development, and healthy pregnancy are working as they should.
The SpermEGT test analyses methylation patterns across more than 1,200 genes that are essential to sperm function. It was developed through a partnership between Sapyen and Path Fertility using the SpermQT epigenetic assay — described as the world's first clinically validated, home-to-lab sperm methylation test.
Role of the SpermEGT DNA Methylation Test in Male Fertility
A sperm cell can look completely normal under a microscope and still fail at its core job. Disrupted sperm methylation affects whether sperm can find, bind to, penetrate, and fertilise an egg. It also influences how the embryo develops after conception.
A 2021 study found that abnormal sperm DNA methylation is consistently associated with impaired spermatogenesis and reduced reproductive outcomes [2].
Another study found that infertile men had nearly a tenfold higher risk of showing disrupted methylation at key fertility-related genes compared to fertile men [3].
Age also plays a role. Higher male age is associated with methylation changes at nearly 1,700 locations on the sperm genome. These changes are correlated with lower fertilisation rates and live birth outcomes in assisted reproduction [4].
For couples undergoing Intrauterine Insemination (IUI) or In Vitro Fertilisation (IVF), understanding sperm methylation status before starting treatment gives clinicians and couples a more informed starting point.
Who Needs the SpermEGT DNA Methylation Test?
SpermEGT DNA methylation test is worth considering if you have:
Normal semen results, but are still unable to conceive
Experienced repeated IVF or IUI failures without explanation
Had recurrent pregnancy loss
Are an older male partner, where age-related epigenetic changes become more relevant
Want a thorough picture of sperm health before trying to conceive
A SpermEGT DNA methylation test acts as quality control for sperm function, leading to pregnancy success and embryo viability during treatments like Intrauterine Insemination (IUI) or In Vitro Fertilization (IVF). Thus, this test can help determine the likelihood of IVF and IUI success rates [7].What Is the Procedure of the SpermEGT DNA Methylation Test?
The process is straightforward. Sapyen sends a test kit to your home. You produce a semen sample using the materials provided and send it back to the certified and accredited laboratories in the prepaid packaging included. The semen sample will remain viable for up to three days in transit.
Once the sample is processed by the labs, the results are reviewed by specialists and returned in a plain-language report.
What Does the SpermEGT Test Measure?
Traditional semen analysis mainly looks at sperm count, movement, and shape. While these factors are important, they do not always explain why some couples still struggle to conceive despite “normal” test results. The SpermEGT DNA Methylation Test takes fertility testing a step further by examining the epigenetic health of sperm.
Developed by Path Fertility and available through a partnership with Sapyen, the SpermEGT test is the first clinically validated home-to-lab sperm epigenetic assay available to the public. Instead of focusing only on the number of sperm present, it analyses DNA methylation patterns across more than 1,200 genes linked to sperm function and early embryo development.
In simple terms, DNA methylation acts like a set of biological instructions that help regulate how genes function. Even when sperm count and motility appear normal, abnormal methylation patterns may affect the sperm’s ability to successfully fertilise an egg and support healthy embryo growth.
Studies have shown that sperm methylation profiles may influence pregnancy success rates, including outcomes in fertility treatments such as IUI. In some cases, couples with poorer sperm methylation profiles experienced significantly lower live birth rates compared to those with healthier profiles - differences that standard semen analysis alone may not detect [8].
By identifying potential issues earlier, the SpermEGT test can help couples and fertility specialists better understand male fertility health and make more informed decisions about the most suitable treatment pathway.
What Happens If You Test Positive for Abnormal Methylation?
Your results show whether your sperm's methylation patterns fall within the expected range (<13%) across the genes assessed. Methylation levels >13% are typically associated with potential infertility [6].
A result showing disrupted methylation should not be viewed as a dead end, but considered as actionable information. You may now have the answers you were looking for. Lifestyle factors known to influence methylation include diet, BMI, smoking, alcohol consumption, and environmental chemical exposure [5].
Your fertility specialist can use these findings to guide next steps, whether that involves lifestyle changes, further investigation, or a specific treatment pathway.
Can You Still Get Pregnant With Abnormal SpermEGT Methylation?
Yes. Disrupted methylation reduces the chances of fertility but does not eliminate them. Many couples with methylation concerns have achieved pregnancy through lifestyle changes, assisted reproduction, or a combination of both.
Cost of the SpermEGT DNA Methylation Test
The SpermEGT DNA Methylation Test is priced at 529 USD through Sapyen (The prices will be market-dependent). This includes the at-home kit, core semen analysis, SpermQT methylation assay, and specialist-reviewed results.
Why Choose Sapyen for SpermEGT DNA Methylation Testing?
Sapyen's SpermEGT test is currently the only at-home DNA methylation test of its kind available globally. Testing is conducted through certified and accredited labs, and you will get the result within 3 weeks.
For the most complete picture of sperm health - covering count, motility, morphology, DNA fragmentation, antisperm antibodies, and methylation together - the Sapyen Complete Analysis combines all of these parameters into one at-home kit. It is worth considering for anyone heading into fertility treatment who wants the full picture before making decisions.

Why is sperm DNA methylation testing important?
It can help fertility specialists understand sperm function more clearly and guide decisions around treatments such as IUI, IVF, or further fertility investigations.
