In-Vitro Fertilization (IVF)
Houston Fertility Center
In-Vitro Fertilization or IVF is a six step process. After controlled ovarian hyperstimulation, eggs are obtained from the ovaries by inserting an aspiration needle through the back of the vagina while under light anesthesia. The eggs are cleaned and husband or donor washed sperm is then added to the droplet containing the egg for fertilization. Micromanipulation of the egg and sperm, such as ICSI would be preformed at this stage, if indicated. The fertilized egg is called a zygote, zygotes develop into embryos. The embryos are incubated in the lab for three to five days. Prior to the embryo transfer the assisted hatching procedure is preformed to encourage implantation.
