Overview

In general, ART procedures involve surgically removing eggs from a woman's ovaries, combining them with sperm in the laboratory, and returning them to a female patient or a gestational carrier. ART also includes egg and embryo cryopreservation (freezing) and egg and embryo donation. The most common type of ART is in vitro fertilization (IVF). Other types of ART, such as gamete intrafallopian transfer or zygote intrafallopian transfer, are rarely performed.

ART does NOT include treatments in which only sperm are handled (such as intrauterine insemination). It also does NOT include procedures in which a woman takes drugs only to stimulate egg production without planning to have the eggs surgically retrieved.
