In the case of women or couples who had a child after their previous cycle, the chances for them to get pregnant in a second cycle using their unused embryos is high, as the fact that they led to a pregnancy the first time confirms. In any case, although the success rates of delayed embryo transfer are high, they are generally somewhat lower than the rates obtained in an IVF cycle with fresh transfer. Once the embryo has been transferred, the woman must continue administering progesterone pessaries to maintain her endometrial lining in an optimal state. Thus, if we have a day-3 frozen embryo, it will be transferred back three days after ovulation. In natural cycles, the ovulation cycle of the patient is examined via ultrasound in order to make it coincide with the IVF procedure. In this case, we take advantage of the natural endometrial growth that occurs in women monthly. By doing this, we simulate the behavior of a natural cycle but controlling it to enhance the chances of pregnancy.Ī frozen embryo transfer can be done in a natural cycle, though. The reason for this name is due to the fact that we are stimulating or replacing the natural menstrual cycle of the woman using artificial hormones, including GnRH analogs, estrogen, and progesterone. The treatment explained above refers to what we usually know as stimulated IVF cycle. Moreover, you should have a full bladder, which makes it easier for everyone to see your uterus via ultrasound scan. Please note that you cannot use make-up or perfumes on the transfer day. After this rest time, you can continue with your normal lifestyle, but avoiding major physical efforts. Additionally, about 3-5 days before the transfer, she has to take progesterone (pills or vaginal pessaries).įinally, you will have to lie flat on the stretcher for about 10-15 minutes.

Then, the medical treatment to follow includes administering estrogens orally or in patches. This can be achieved using oral contraceptives as well. The following are the main steps: Endometrial preparationįirstly, the IM takes GnRH analogs to block the natural regulation of hormones, and control her cycle artificially. Daily injections or regular monitoring is unnecessary, and the same happens with surgical procedures or uncomfortable side effects. The protocol to follow in FET cycles is more comfortable and simpler than in conventional cycles. In any case, the patient who is undergoing the second part should prepare her endometrial lining adequately to increase the chances for embryo implantation, thereby increasing the likelihood of getting pregnant.
