Intrauterine Insemination (IUI)

Intrauterine Insemination (IUI) is a procedure which allows placement of the sperm high in the uterus, close to the fallopian tubes where fertilization occurs. The insemination is done near the time when ovulation or release of the egg from the ovary will occur. During the procedure, a thin, flexible catheter containing prepared sperm is inserted through the opening in the cervix into the uterine cavity.  IUI is done at our office on weekdays and on weekends.

IUI is done 24-36 hours after Ovidrel injection if the female partner is having ultrasound monitoring (Ovidrel is given if the eggs are ready for fertilization as determined by ultrasound monitoring).

If the female partner is not having ultrasound monitoring, then IUI is done approximately 24 hours after an LH (leutinizing hormone) surge. The LH surge is the hormonal message that signals the ovary to release the egg. Kits are available to test for the presence of LH in the urine. A high level or “surge” of LH means that ovulation will occur in approximately 24-36 hours. Once ovulation has occurred, the egg (oocyte) is available for fertilization for about 24 hours.
