-12. What is CAT (Cumulus Aided Embryo Transfer)
When a few of the feeder cumulus cells on which the embryo is being cultured are transferred along with the embryo into the uterus, the technique is referred to as Cumulus Aided Embryo Transfer (CAT). At Jaslok Hospital, we use the patient's own cumulus cells as the feeder layer over which her embryos are cultured. These cumulus cells are rich in growth factors such as Insulin-like Growth Factor and Vascular Endothelial Growth Factor. These ensure the proper growth of the developing embryos. In order to improve the technique we go a step further. At the time of embryo transfer we add 30 microlitres of the cumulus cells to the embryos so that the nutrients secreted by the cumulus cells continue to be provided in vivo thereby enhancing pregnancy rates.
