blastocyst transfer

Blastocyst transfer is a stage in in vitro fertilization (IVF) where a developed embryo, known as a blastocyst, is implanted into the uterus. After fertilization, embryos grow for about five days until they reach the blastocyst stage, which is when they have formed a fluid-filled cavity and can better implant in the uterine lining. This method often increases the chances of pregnancy compared to transferring earlier-stage embryos, as blastocysts are more advanced and have a higher likelihood of successful implantation. It allows for more selective embryo choices based on development quality.
