IUI is a simple artificial insemination technique and is performed on patients with unexplained infertility. Patent tubes are necessary for IUI and a laparoscopic or a hysterosalpingogram (x-ray of the tubes and uterus) investigation might be needed. IUI is a fertility treatment that involves placing sperm directly into the uterus. It is an effective technique with a high success rate. Sperm can either be provided by your partner or from a donor. The semen is washed depending on quality and immune status. The ovaries are stimulated as per IVF cycle. Ovulation is induced at the time of insemination. The semen is then loaded into a cannula and inserted into the uterus.
IUI can be done in a spontaneous cycle when the women is ovulating spontaneously or in a stimulated cycle (Clomid or injectable). This is called controlled superovulation and washed artificial insemination. Should there be signs of hyperstimulation, then the programme may be aborted or converted to IVF.
