The role of mitochondrial DNA in reproduction
Svobodová, Mariana ; Daňková, Pavlína (advisor) ; Jelínková, Ladislava (referee)
The bachelor's thesis focuses on the role of mitochondrial DNA (mtDNA) in human reproduction, especially describing the differences in mtDNA dynamics in oogenesis, spermatogenesis and early embryo development. The physiological function of mtDNA is complemented by its pathologies and their effect on fertility and the ability of the embryo to implant successfully. Furthermore, mtDNA is discussed as a possible diagnostic marker in the evaluation of the quality of sperm, eggs and embryos. These findings of these studies are especially significant for assisted reproduction, where the goal is to select the highest quality embryo with the greatest implantation potential. The work also briefly mentions the presence of cell free mtDNA in the mother's blood and its connection with the development of preeclampsia. Key words: mtDNA, mitochondria, reproduction, (in)fertility
