About Episona

Episona is a molecular diagnostics company transforming men’s health by analyzing epigenetic patterns that contribute to human disease.

Epigenetics is the heritable, long-term modification of gene activity without changes to the underlying DNA sequence. These alterations are acquired through normal human development, aging, environmental exposures, and disease.  In other words, experiences you have in your lifetime can change the way your DNA works. Moreover, these epigenetic changes may be inherited by future generations.

One type of epigenetic marker is DNA methylation (the binding of methyl groups to DNA, which control the expression of different gene groups). Episona believes that abnormal modifications to the normal DNA methylation pattern of the sperm genome strongly impacts male fertility. Accurately measuring these changes may uncover hidden male factor infertility in cases of unexplained infertility and recurring IVF failure not captured in the standard testing.

Episona’s first product, The Male Fertility Panel (MFP),  evaluates epigenetic abnormalities in the sperm genome to create a significantly more accurate diagnostic for male infertility

25% of infertile couples have the negative diagnosis of unexplained infertility. The MFP will recognize hidden male factor in these cases, moving them to IVF or IVF-ICSI more quickly.

IVF cycle failures cause significant financial and emotional stress to the patient. The MFP will detect contributing hidden male factors that cause cycle failure, increasing decision power.

Male Fertility Panel (MFP)

The difference between an eye and a nose…is clearly neither genotypic nor phenotypic. The appearance of a particular organ is the product of the genotype and the epigenotype, reacting with the external environment.

- Conrad H. Waddington, 1947

Sperm + Epigenetic Mechanisms

Who is affected by infertility?

of couples attempting to have children suffer from infertility. Around 1.2 million men seek help for infertility every year.
of infertile men are accurately diagnosed with male factor infertility using the semen analysis. Guzick, 2001, NEJM
of couples receive the diagnosis of unexplained infertility, meaning the cause of the couple's infertility is unknown,
of IVF cycles fail for reasons unknown. Sperm is suspected to contribute significantly to this failure rate.

What does the whole solution look like?


Episona’s Male fertility Panel is in the process of clinical and technical validation.  Would you like us to keep you informed of our progress?

Help Us Create A Better Test for Male Infertility

At Episona, we’re developing a better test for male infertility that looks much deeper than the standard semen analysis. We believe the most successful way to do that is by communicating and working with the people who are looking for a better solution.

That’s where you come in.

What tests do you currently use to diagnose male infertility? Where do these tests fall short? How do we increase the chance of a successful outcome for both you and your patients? Stay connected with Episona and we will keep you informed about the scientific progress on the Male Fertility Panel (MFP) and opportunities to collaborate with us.
