Preparing for Embryo Transfer

In vitro fertilization involves implanting fertilized embryos in the uterus in order to achieve pregnancy. When the eggs are ripened, an egg retrieval procedure is done to remove them. After the eggs are fertilized and begin to grow into embryos, the embryo transfer procedure is done.

If donor eggs or frozen embryos are used, the woman's cycle must be prepared for implantation, just as would naturally happen during a menstrual cycle. Depending on the health and infertility history of the woman, either the natural cycle will be followed or estrogen and progesterone will be given.

This is a relatively simple procedure and is generally done two or three days after the egg retrieval. The embryos are placed in a catheter, which will be used to transfer them into the uterus. The doctor uses ultrasound to guide the procedure. The embryos are placed near the top of the uterus.

Most women don't experience any pain during the embryo transfer procedure. Some may feel a small amount of cramping as the catheter is moved through the cervix, but this is generally very mild. After the procedure, you will need to remain in the clinic, lying on your back. In about two hours, you will be able to go home.

The next step will depend on several factors and varies from woman to woman. Some women are advised to take progesterone suppositories for a certain amount of time after the transfer. In other cases, an injection of HCG may be given to encourage implantation. This is done to increase the production of progesterone, which is essential during implantation.

When you are sent home, you may be advised to restrict activity. The advice varies. Some doctors believe resting for 24 hours is beneficial, while others believe this is not necessary. The research is mixed and it isn't clear whether resting has any influence on the outcome of the procedure.

Although the research isn't clear and there may not be any benefit, resting won't hurt. Many women choose to err on the side of caution and restrict activity for the first twenty four hours after the embryo transfer.
