Do morphokinetic parameters vary between male and female preimplantation embryos?
Retrospective cohort study of 175 cycles between March 2018 to June 2021 from two reproductive centers. It included time-lapse data from 92 female and 83 male preimplantation embryos exclusively issued from fresh oocyte donation. Only fresh elective single-embryo transfers on day 5 were assessed and sex of the embryo was confirmed at birth. The morphokinetic parameters analyzed were measured in hours post insemination. A two-tailed Student’s t-test was used to compare morphokinetics between embryo sexes and a p<0.05 was considered statistically significant.
