Objective: To determine the blastulation rate for an In Vitro Fertilization (IVF) laboratory and determine how it was effected by patient and physician variables.
Design: Retrospective Cohort.
Setting: Community-based IVF center staffed by one embryologist and five physicians from 2017-2019
Interventions:Controlled ovarian hyperstimulation, oocyte retrieval, and embryo culture for up to six days (1005 cycles and 11,022 oocytes
Main Outcome Measure: The proportion of pre-zygotes that developed into blastocysts.
Results: The overall blastulation rate was 70%. The blastulation rate was not significantly affected by maternal age. The blastulation rate was decreased when surgically obtained sperm were used (59.2%; p<0.0001), but not sign.. View More»
