How do I undergo a Thawed embryo transfer in a hormone replacement cycle?
This applies if you do not have a regular menstrual cycle or are receiving donated oocytes. When required, withdrawal bleeding is induced with one 5mg tablet of Norethisterone twice daily for five days. In order to simulate the proliferative phase of the menstrual cycle, Estradiol valerate (Progynova) 2mg, two tablets three times a day are given from day 3 of your menstrual cycle for 12 to 20 days until the endometrium is more than 8mm in thickness and there is clear cervical mucus. To simulate the secretory phase of the menstrual cycle, vaginal progesterone 90mg (Crinone) is inserted two times a day for 20 days Embryo replacement takes place 2 days after starting progesterone. 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 viabilit
