Abstract:
In our series, a very high prevalence of chromosomal abnormalities was observed in spontaneous miscarriages, irrespective of how pregnancy was achieved, by assisted reproductive technology (ART) or natural conception. This high prevalence was equally represented in both groups, with no statistical difference in type of chromosomal abnormalities or in total frequency; however, the incidence of monosomy X is increased and the polyploidies are decreased in abortus after intracytoplasmic sperm injection (ICSI) when it is compared with miscarriages after spontaneous gestations.
