In this the uterine cavity is stimulated by scratching the cavity using a thin plastic cannula called pipelle. This procedure is a simple 5 min, painless procedure which is done in the OPD using a thin plastic or steel cannula, just prior to or after the menstrual period of the cycle, in which an embryo transfer is being planned. Many studies have shown an improvement in success rates after pipelle, especially in those patients who have had repeated IVF failures. Our unit routinely does pipelle with great outcomes.
