Fertilization of eggs

The eggs are held in a special media and cultured in an incubator until insemination. Two days after fertilization, normal embryos will be between two and six cells. Three days after fertilization, normal embryos will be between seven and nine cells. On the fourth day of fertilization, most normal embryos will have reached the morula Then, after 16-20 hours have passed, they are checked to see if any eggs have been successfully fertilized.
Finally, hormone medicines will be supplied to aid in the preparation for lining the womb to receive the embryo.

Transferring Embryos

Sometimes, more than one embryo is placed in the womb. It is important that the doctor and the couple wishing to have a child discuss how many embryos should be transferred.

The embryo is transferred using a thin tube that enters the womb through the vagina. When the embryo sticks to the lining of the womb, healthy embryo growth begins.
