intrauterine insemination

Intrauterine insemination (IUI) refers to the transfer of "washed" semen or sperm directly into the uterine cavity though a catheter. By bypassing the mucosal surface of the cervix, which acts as a barrier, it increases the chance of sperm reaching the uterine cavity and tubes. Intrauterine insemination is most often used when the male has reduced sperm count or motility.
