The procedure of work (manipulations) with frozen embryos is simple, convenient and economical. It is not required to have daily injecting or ultrasound control. You do not need to carry out procedures that require the use of sedatives, and in most cases, there is no side effects, because during preparation the level of hormones will be as close as possible to the norm.
The treatment is based on the preparation of the uterus for being ready to receive the unfrozen embryo. It is necessary to use a hormonal patch or tablet for two weeks before the procedure of the embryo transfer.
The preparation of the uterus for an unfrozen embryo transfer begins with menstruation. In ten days after it, an ultrasound examination confirms the uterus’s readiness and then unfreezing and transfer of embryo are planned.
Vaginal progesterone is used 3 – 5 days before the embryo unfreezing.
The technique of cryopreserved embryo transfer is identical to the procedure with fresh embryos, it does not require any other preparation or provide additional discomfort. Further recommendations are the same for both frozen and fresh embryos, and should have the same medical treatment (vaginal patches and other hormones) before the realization of pregnancy test.
To sum up, we can say that the procedure is very simple: hormonal patches are fastened to the body for several days, control ultrasound is performed, progesterone is taken and the embryo is transferred.
