blastocyst transfer

A type of in vitro fertilisation consisting of the transfer of a blastocyte (the fertilised egg, which has divided a number of times) to the endometrium.

Pros
Greater chance of becoming pregnant than with 2–3-day embryo transfer.

Cons
May not result in any embryos at all; greater chance of twin gestation.

blastocyst transfer

An assisted reproduction technique in which a zygote created by in vitro fertilization is incubated in the laboratory to the pre-embryonic stage of the blastocyst before being placed in the uterus.
