Resumo

Aim. To investigate the feasibility of in vitro maturation (IVM) of human oocytes as a fertility-sparing technology in patients diagnosed with cancer during pregnancy. Materials and methods. Ovariectomy was performed during a cesarean section (CS) or elective surgery. Immature oocyte-cumulus complexes were retrieved from the ovarian medulla and underwent 48-72 h in vitro maturation. All mature oocytes were vitrified. The percentage of matured and degenerative oocytes and the number of cryopreserved oocytes were estimated. Results. In all three cases of patients diagnosed with cancer during pregnancy, oocyte-cumulus complexes were obtained. Six, 20, and 24 oocyte-cumulus complexes were isolatedfrom the first, the second, and the third patient, respectively. The oocyte maturation rate was 33.3%, 30.0%, and 54.2%, resulting in vitrification of 2, 6, and 12 oocytes, respectively. Conclusion. Oocyte-cumulus complexes can be successfully isolated from the ovarian medulla after ovary removal during cesarean section or elective surgery. In vitro-matured oocytes can be vitrified or used for in vitro fertilization (IVF) to preserve fertility.
