According to American pregnancy association, IVF is the process of fertilization by manually combining an egg and sperm in a laboratory dish. First of all, Fertility medications are prescribed to control the timing of the egg ripening and to increase the chance of collecting multiple eggs during one of the woman's cycles. Then eggs are retrieved through a minor surgical procedure under ultrasound guidance. Then sperms are obtained by ejaculation and insemination is allowed to occur. In this process, the sperm and eggs are placed in incubators located in the laboratory which enables fertilization to occur. Once this occurs, the fertilized eggs are considered embryos.
Lastly the embryos are usually transferred into the woman's uterus anywhere from one to six days later.
