Non-Medical Embryo Sex Selection Results in Reduced Implantation Compared to the Transfer of the Highest Morphological Grade Blastocyst

A comment on: A non-randomized clinical trial to determine the safety and efficacy of a novel sperm sex selection technique

“…In many cases of PGT-A for sex selection, however, a choice has to be made between the best quality embryo and an embryo of the desired sex.

The new method may decrease the number of possible conflicts between quality and desired sex because of the higher proportion of embryos of the desires sex.…”
