Frozen Embryo Transfer
Frozen thawed embryos can be transferred into the uterus either in a natural cycle or in a down regulated cycle.Natural Cycle FET:
It can be done if you have ovulatory cycles. Your cycles would be monitored by scans for follicular growth and ovulation and the embryos are transferred at the appropriate time following ovulation.Down Regulated FET:
Your natural cycle is suppressed using medications and a period is artificially induced, followed by hormonal medication to prepare the uterus. Once the lining of the uterus is ready, the embryos are transferred at the appropriate time. Once the frozen embryos are thawed to room temperature, only about 80-85% of them survive. Upon transferring these embryos, the success rate is good as a fresh embryo transfer approximately 50-55%.
