Epigenetics refers to heritable modifications in gene expression that occur without altering DNA sequence. In male reproduction, epigenetic mechanisms such as DNA methylation, histone modification, and non-coding RNA regulation influence spermatogenesis and embryo development.
Environmental exposures, nutritional erotic status, stress, and aging can induce epigenetic alterations in sperm cells. These modifications may not only impair fertility but also affect offspring health outcomes. Abnormal epigenetic patterns have been associated with reduced fertilization success and increased miscarriage risk.
Advanced andrology incorporates epigenetic research to better understand idiopathic infertility cases. The emerging field of sperm epigenomics promises to refine diagnostic approaches and inform preventive strategies.
