In this case, the woman's eggs are fertilized with sperm, but the resulting embryos are placed in the gestational carrier's uterus.

The number of embryos transferred is typically based on age and number of eggs retrieved. Since the rate of implantation is lower for older women, more embryos are usually transferred - except for women using donor eggs or genetically tested embryos. Most doctors follow specific guidelines to prevent a higher order multiple pregnancy - triplets or more - and in some countries, legislation limits the number of embryos that can be transferred.

Make sure you and your doctor agree on the number of embryos that will be transferred before the transfer procedure. What will you do with any extra embryos?

The eggs are removed from the follicles through the needle, which is connected to a suction device.

In intracytoplasmic sperm injection ICSIa single healthy sperm is injected directly into each mature egg. ICSI is often used when semen quality or number is a problem or if fertilization attempts during prior in vitro fertilization cycles failed. Three days after fertilization, a normally developing embryo will contain about six to 10 cells.

By the fifth or sixth day, the fertilized egg is known as a blastocyst - a rapidly dividing ball of cells. The inner group of cells will become the embryo. The outer group will become the cells that nourish and protect it.
