A new way to diagnose infertility in men

A new American study has revealed that infertile men exhibit certain biomarkers on the DNA of their sperm (identified using epigenetic analysis techniques) that are not present in fertile men. Researchers also identified specific biomarkers in infertile patients who responded to hormonal therapy to treat infertility, compared to men who did not undergo such treatment.

Study Results

The study, conducted by Michael Skinner, a reproductive biologist at Washington State University, involved analyzing data from 120 men and was published in November of this year in the scientific journal Scientific Reports (Nature). Skinner and his team of scientists discovered that infertile men exhibit patterns of epigenetic molecules or biomarkers attached to the DNA of their sperm. These biomarkers are not present in fertile men. The scientists also identified epigenetic biomarkers in infertile patients who responded positively to hormonal therapy, which distinguished them from men who did not receive such treatment.

According to the authors, the presence of epigenetic biomarkers not only proves infertility but also predicts the effectiveness of various treatments, including hormone therapy. For example, the study describes the case of a patient whose biomarkers were identified and who, after hormonal therapy, was able to achieve a significant improvement in spermatogenesis, leading to a successful conception attempt. This approach significantly accelerates the diagnostic process and the selection of optimal treatment.

Importance for Medicine and Couples Suffering from Infertility

The research by Michael Skinner and his team could in the future provide doctors with a reliable method for screening infertility in men. This would allow for earlier identification of the problem, minimizing the duration and cost of diagnosis and treatment, and increasing the chances of successful fertilization.

For couples facing difficulties in conception, the new diagnostic method could represent a real breakthrough, as it identifies the cause of the problem more quickly, provides more accurate data than traditional methods, and reduces the likelihood of unjustified treatment. In cases where infertility is due to a male factor, the availability of an accurate diagnostic tool will enable quicker identification of the problem and the commencement of appropriate treatment. Furthermore, the ability to predict the effectiveness of therapy will give doctors the opportunity to tailor their approach for each patient.

Development Prospects

In the future, this research could lead to the creation of affordable and widely used tests based on epigenetic biomarkers. These tests could become part of the standard examination in cases of suspected infertility. They will also help to better understand the mechanisms of infertility and open new therapeutic options.

Given that one in six men experiences difficulties in conception, the development of these methods is likely to improve the quality of life for millions of people. For example, in the United States and Europe, about 15 to 20% of couples experience difficulties in conceiving, highlighting the need for new diagnostic approaches. In addition to natural conception, these techniques may be useful for improving the effectiveness of IVF programs (in vitro fertilization), including variants of IVF with sperm donor. Continued research in this field could lead to a better understanding of the role of epigenetics in male fertility and open new horizons for medicine.

Epigenetic biomarkers offer a unique opportunity to transform the diagnosis and treatment of male infertility. Accurate analysis methods based on the latest scientific advancements can significantly improve the chances of successful conception and give couples greater confidence in the future. New technological and therapeutic advancements could complement analyses and become the standard in reproductive medicine.
