Reproductive ageing and its reflection in obstetrics in Czechia Abstract The aim of this thesis is to explore trends in obstetrics in Czechia in the context of increasing maternal age. The key issue is the rise in the percentage of births performed by caesarean section. The first part of the work sums up the current knowledge of fertility development and describes the selected effects of fertility postponement, health risks, especially of caesarean sections.
