Information of FET
If you have frozen embryos at ART Medica you can have FET ( frozen embryo transfer ) in a natural cycle or programmed cycle. For an FET cycle, you need to call the clinic upon commencement of menstruation so we can plan the treatment. If a natural cycle is elected you need to have ultrasound examination on cycle day 10. After that examinations are done every 2-3 days until ovulation is confirmed. Frozen embryo transfer is performed 2-3 days after ovulation.
In a programmed cycle the treatment starts on cycle day 21 when the GnRH analog medication ( Suprefact injections or Synerela nasal spray ) is administered to down regulate the pituitary gland. Menstruation will start 10 -14 days after commencement of the GnRH analog medications. At this time an ultrasound examination will be conducted. Then the dose of the GnRH analog medication is halfed and estradiol medication is introduced in increasing dosage over the next 2 weeks. A ultrasound examination is then performed and if the endometrium ( the lining of the uterus) is sufficient
a Progesteron medication ( Lutinus / Geston inj.) is started and the GnRH medication stopped. The transfer of the embryos will be preformed 2-3 days later. Detailed information on the administration of the medication will be provided by your doctor or nurse. After the transfer of the embryos you will continue on estradiol medication 6mg (3x 2mg) and the Progesterone medication over the next 2 weeks until the results of the pregnancy test. If the pregnancy test is positive you need to continue on the Estradiol 8mg (4 x2mg) and the Progesterone medication for the next 10 weeks. A pregnancy ultrasound is performed at 6 weeks and 8 weeks (4 and 6 weeks after the transfer)
Results of FET . The chance of pregnancy after FET is 30% . The success rate from a natural and controlled cycle is similar. The controlled cycle is more convenient for couples who live far away or when the menstrual cycle is irregular.
