Embryo transfer is a critical step in IVF where carefully selected embryos are placed into the uterus to achieve pregnancy, directly impacting embryo transfer success rates and overall IVF outcomes significantly. This procedure can involve a Day 3 embryo transfer, Day 5 blastocyst transfer, or frozen embryo transfer, depending on embryo development, patient health, and specific fertility requirements. Proper handling, timing, and precise technique are essential for a successful embryo implantation process, ensuring embryos have the best possible chance to attach, grow, and develop naturally. Optimized embryo transfer improves pregnancy success, reduces complications, and is vital for achieving positive IVF treatment results with higher consistency.
