Embryo Transfer (ET)
Definition - What does Embryo Transfer (ET) mean?
An embryo transfer is the last step in an in vitro fertilization (IVF) process where embryo(s) that have been cultured in a laboratory are placed into a uterus to facilitate conception. The preferred time for transferring embryos is typically day two, three or five after the egg retrieval.
FertilitySmarts explains Embryo Transfer (ET)
The embryos are gently placed into a fine catheter that will pass through the vagina and cervix in its way to the uterus. Around two weeks later, a pregnancy blood test and an ultrasound will be done, in order to check for viability and implantation of the transferred embryos.
There is no agreement among fertility specialists if resting or going about a regular routine would change the result of this procedure. Conception at this point depends mostly on successful implantation and the genetic quality of the fertilized egg.
Progesterone is a supplemental medication that is often required after an embryo transfer. The main role of this hormone is to sustain a pregnancy and supplementation is often discontinued after a pregnancy is confirmed and is progressing normally.
