Short description of the thesis

How stable are epigenetic marks in human sperm?

Beyond the genetic information carried by DNA, the epigenome represents chemical modifications that help regulate how genes function. Some of these marks are particularly important for a process called genomic imprinting, which ensures that certain genes are expressed depending on whether they are inherited from the mother or father.

This PhD project investigates how reliably these marks can be measured and whether they are influenced by paternal age, body weight, or methods used to select sperm for fertility treatment. The findings reveal stable imprinting patterns across the investigated regions, contributing to our understanding of sperm epigenetics and reproductive health.
