Sperm age can help predict successful pregnancy
The study found that the cumulative probability of pregnancy at 12 months was 17% lower for couples with a male partner in the older younger sperm epigenetic aging groups.
Epigenetic aging sperm is biological
“Temporary age is a significant determinant of fertility and success in couples trying to conceive, but chronological age does not include genetic and extrinsic factors, environmental conditions accumulate, and is therefore a proxy for the ‘real’ biological age, says researcher J. Richard Pilsner from the journal.
“Semen quality results according to World Health Organization guidelines have been used to assess male infertility for decades, but they are still poor predictors of reproductive outcomes. , the ability to capture the biological age of sperm may provide a new platform for better assessing male contributions, adds Pilsner.
For the study, published in the journal human reproduction, The research team included 379 male partners of couples who had stopped using birth control to get pregnant.
