Intra-uterine Insemination (IUI)

IVF

Intrauterine insemination (IUI) is the placement of washed sperm into the uterus, at the time of ovulation. The sperm is washed in order to increase sperm motility, to filter out abnormal sperm, and to remove bacteria and other substances which would otherwise irritate the uterine lining. Washed sperm is more motile and more likely to achieve fertilization than unwashed sperm, especially in men with sperm problems, or in older women.
