| Popis: | Immature oocyte recovery followed by in-vitro oocyte maturation and in-vitro fertilization is a promising new technology for the treatment of human infertility. The technology is attractive to potential oocyte donors and infertile couples because of its reduced treatment intervention. Immature oocytes were recovered by ultrasound-guided transvaginal follicular aspiration. Oocytes were matured in vitro for 36-48 h followed by intracytoplasmic sperm injection (ICSI). Embryos were cultured in vitro for 3 or 5 days before replacement. Assisted hatching was performed on a day 5 blastocyst stage embryo. Embryo and uterine synchrony were potentially enhanced by luteinization of the dominant follicle at the time of immature oocyte recovery. Mature oocyte and embryo production from immature oocyte recovery were similar to the previous IVF results of the patients. A blastocyst stage embryo, produced as a result of in-vitro maturation, ICSI, in-vitro culture and assisted hatching, resulted in the birth of a healthy baby girl at 39 weeks of gestation. |
