Do children born after embryo vitrification differ from siblings born after fresh embryo transfer? Open
Our results in siblings born after IVF/ICSI and after embryo biopsy, indicated that FET is associated with higher birthweight, even after controlling for confounders.

Mitochondrial DNA variants segregate during human preimplantation development into genetically different cell lineages that are maintained postnatally Open
Humans present remarkable diversity in their mitochondrial DNA (mtDNA) in terms of variants across individuals as well as across tissues and even cells within one person. We have investigated the timing of the first appearance of this vari…
