IVF is the basic assisted reproduction technique, in which fertilization occurs in vitro (literally, in glass). The man’s sperm and the woman’s egg are combined in a laboratory dish, and after fertilization, the resulting embryo is then transferred to the woman’s uterus. The five basic steps in an IVF treatment cycle are superovulation (stimulating the development of more than one egg in a cycle), egg retrieval, fertilization, embryo culture, and embryo transfer.
