How does the cultivation of embryos occur?

#vittoriavitaQuestionAnswer

The embryologist fertilizes the eggs in vitro using ICSI and cultivates them to the blastocyst stage (usually for 5-6 days). The obtained embryos will be examined under a microscope and the highest quality ones will be selected — with even cells and without structural changes.

A couple can use:

• Own oocytes. There are two ways:

1. Synchronization of cycles. The doctor prescribes hormonal drugs to the potential and surrogate mother to synchronize their cycles. A potential mother takes pills so that the ovaries can produce as many eggs as possible. Surrogate mother needs hormones to prepare the body for pregnancy. The doctor counts the program to the day. This is necessary so that after the creation of the embryos, the uterus and the endometrium of the surrogate mother are ready for embryo transfer and pregnancy.
2. Without synchronization of cycles. The doctor creates embryos, conducts PGD and cryo-preserves them. After that, the surrogate mother takes a course of hormonal drugs and, when her body is ready, the doctor performs embryo transfer. That is, a woman is prepared for transfer only after PGD, when we know which of the embryos are healthy.

• Donor oocytes. In this case, the donor and the surrogate mother undergo a similar hormonal preparation.

The cost of drugs is included in the cost of the program.
