Patient's question:
Why do some people transfer day 3 embryos, while others transfer day 5 embryos?Doctor's answer:
Is it better to transfer a third-day cleavage embryo or a fifth-day blastocyst? This depends on the patient's condition. For younger patients, if the embryo is cultured to the fifth day, the success rate of transfer is usually much higher than with a third-day cleavage embryo. However, if the patient is older or the embryo quality is not very good, it may not be possible to culture the embryo to the fifth day in vitro. In such cases, it is recommended to consider transfer on the third day.
