As more people are choosing to have children at older ages, it is essential to understand how this demographic shift may affect the next generation. In this study, we are initially investigating whether the age of a father at childbirth affects certain aging markers in their children. Specifically, we are looking at the length of telomeres in white blood cells (LTL), which is a crucial indicator of how many times cells can divide before they start to become damaged or die. Research shows that older fathers often have longer telomeres in their sperm. These longer telomeres can be passed on to their children, giving them longer LTL from the start. Our goal is to confirm these findings while also considering other influencing factors that previous studies might have missed.
Additionally, longer LTL could play an essential role in how the reproductive system ages in women. By slowing down this particular aging process, longer LTL might delay menopause and prolong the fertile years. Consequently, we assess whether a father’s age at childbirth is linked to a later onset of menopause in daughters, suggesting that longer telomeres help prolong their reproductive years. This part of the project could thereby unveil a novel epigenetic pathway that links longer reproductive lifespans with older paternal age at childbirth.
By the end of this research, we hope to provide clearer insights into whether the age of fathers at the time of childbirth can impact not just how quickly their children’s cells age, but also the reproductive health trajectories of their daughters. This understanding is crucial as the trend towards older parental age continues.
