How do I undergo a Thawed embryo transfer in a natural cycle?
If you have a regular ovulatory cycle. One way is to test your urine twice daily from day 12 to day 16 for the Luteinizing hormone surge. This would show as a definite double line in a plastic cassette. You will be given an injection of HCG 10,000 units (Pregnyl) under your skin of your tummy . If your embryos have been frozen at the 6 or 8 cell stage, transfer will take place five days after the injection. On the day of transfer, you will have a trans abdominal ultrasound scan to determine the position of your uterus and the length of the cavity. The number of embryos to be transferred will be decided upon and they will be thawed and cryo preservative washed away. The thawed embryos would be inspected for viability before transfer. Two days before embryo transfer, luteal phase support is started. Vaginal progesterone 90mg (Crinone) is inserted two times a day for 20 days. On the day of embryo transfer, the implantation (luteal) phase support is also augmented with HCG (Pregnyl) 2,500
