It is recommended for males who have mild to moderate decrease in sperm count or motility while female partners are normal with patent fallopian tubes. Sometimes IUI may be combined with ovulation induction in female partners with mild endometriosis, or who do not ovulate regularly. Rarely IUI is offered to some couples who have no any apparent cause for infertility and are normal.

Then she will generally be advised medications (tablets and / or injections gonadotropin) from day 2 or 3 of your menses for 7-10 days. The response will be monitored by pelvic ultrasound every 3-4 days and when the follicles are of appropriate size, the final ovulation will be triggered with an injection of hCG and subsequently the IUI procedure is planned which is approximately 36 hours later.
Male partner: The semen sample would be examined first. He then needs to provide his again provide his semen sample on the day of IUI which is then processed in the laboratory after which the semen sample are injected in the female partner’s uterus.
