Overview
Intrauterine insemination (IUI) is a procedure used to treat infertility. During IUI, specially prepared sperm are placed directly into the uterus, where a baby develops. Another term for this procedure is artificial insemination. The goal is for the sperm and egg to unite in the fallopian tube, leading to pregnancy. IUI can be timed with a person's menstrual cycle, and it's commonly used for various reasons, including unexplained infertility, endometriosis-related infertility, and mild male factor infertility.
