| الوصف: | This study aimed to evaluate the rates of euploidy, aneuploidy, and mosaicism in preimplantation genetic testing for structural rearrangements (PGT-SR) cycles from chromosomal inversion carriers. In addition, this work also focused on assessing the impact of some contributors on the incidence of parental originating aneuploidy and mosaicism.This retrospective review enrolled chromosomal inversion carrier couples of whom the females were under 38 years old undergoing PGT-SR at a single academic reproductive center. Subgroups were divided according to the gender of carriers, the inversion type, and the semen parameters of male carriers (male factor infertility (MF) or non-MF). Patient demographics, cycle characteristics, and PGT-SR outcomes were compared among subgroups.A total of 71 PGT-SR cycles from 57 inversion carrier couples were included for analysis. Among the 283 blastocysts, 48.4% were identified as euploidy, 27.9% as aneuploidy, and the remaining 23.7% as mosaicism. Only 32.9% of aneuploid embryos and 1.5% of mosaic embryos involved the parental inversion chromosomes. Notably, the female inversion carriers seemed to produce more parental originating aneuploid embryos than male inversion carriers (45.5% vs 23.9%, p = 0.044).The type of inversion and sperm parameters of male chromosomal inversion carriers did not affect the ploidy status of embryos. The incidence of parental originating aneuploidy in inversion carrier couples is lower than expected. For male chromosomal inversion carriers with normal sperm condition whose female partners are under 38 years old, natural conception combined with prenatal diagnosis could be provided as an option during fertility counseling. |
