This is an office procedure which involves placing "washed" sperms into the womb, with a small plastic tube called catheter. Sperms are taken from the husband. If required frozen or donor sperms can be used, depending upon patient's situation and also needs written consent. The sperms are washed several times to remove substances like prostaglandins that can cause cramping or shock. Once the semen is washed and good motile sperms are separated, it is transferred into the womb of patient via a catheter to achieve best chance of pregnancy. This procedure is preceded by ovulation monitoring by transvaginal ultrasound and if required ovarian stimulation with gonadotrophins or clomiphene citrate. There are different methods of processing the semen and the cost of each process may be different.
