Vitrification of oocytes

Vitrification of oocytes (egg cells):

1. thorough examination;
2. daily hormonal injections (10-12 days);
3. follicle puncture (15-20 minutes);
4. immediate freezing (vitrification) of oocytes.

Vitrification of embryos:

1. thorough examination;
2. daily hormonal injections (10-12 days);
3. follicle puncture (15-20 minutes);
4. fertilization by ICSI method;
5. vitrification of embryos (5th day of development).

It is preferable to vitrify chromosomally suitable embryos for transfer (selected with PGT).

Benefits of embryo freezing:

1. increase of the pregnancy likelihood due to repeated transfers of embryos into the uterine cavity. Vitrification of embryos is a kind of "insurance" if pregnancy does not occur in this cycle;
2. decrease of the drug (hormonal) load on the woman's body during repeated transfers because there is no need for repeated stimulation of superovulation and follicle puncture;
3. a significant reduction of the financial expenses of patients;
4. the possibility of conceiving second and subsequent children in the future;
5. the possibility to preserve the remaining embryos of good quality;
6. the possibility of sharing embryos with other infertile couples.
