AIH (artificial insemination by husband): A procedure in which a fine catheter (tube) is inserted through the cervix (the natural opening of the uterus) into the uterus (the womb) to deposit a sperm sample from the woman's mate directly into the uterus. The purpose of this procedure is to achieve fertilization and pregnancy. AIH is distinguished from artificial insemination by donor (AID) in which the donor is a man other than the woman's mate. AIH is also known as homologous insemination.
