Despite extensive research in this area, in many cases, the underlying causes are unknown. Epigenetic changes control a series of processes within the body, including male fertility. Classification of infertile men using a more detailed analysis of DNA methylation patterns could reveal a new level of low rates of fertilization, implantation, or pregnancy. In this context, it seemed to us to use the techniques available to evaluate the degree of global methylation of DNA in infertile patients who have modified sperm counts, but also those who apparently do not have a clear cause of infertility. For this we used the Quest 5mC-Zymoresaerch-ELISA kit that can detect within about 5 hours the global level of genome methylation. Claims on which common illnesses have an epigenetic base are still open to speculation, but if true, it can imprint a new direction in medicine. Our data, although from a pilot study, are consistent with those in the literature. A recent study has shown that DNA methylation levels were significantly higher in oligoasthenoteratozoospermia patients than in the control group and the increase in global DNA methylation and histone retention in men with oligoasthenoteratozoospermia.
