Objective: To describe pregnancies that resulted from in vitro matured oocytes derived from stimulated IVF cycles before cancellation owing to poor response of gonadotropins.
Design: Case report. University hospital.
Patient(s): Eight patients who underwent in vitro maturation.Immature oocyte retrieval, in vitro maturation of immature oocytes, fertilization, and ET. Luteal support with progesterone and plvyeron was given.
Main outcome measure(s): Pregnancy and live birth.
Result(s): Three pregnancies (two live births and another ongoing) were achieved after immature oocyte retrieval, in vitro maturation, fertilization with ICSI, and ET.
Conclusion(s): Immature oocyte retrieval from poor responders during stimulation, followed by in vitro maturation, may be an alternative before the cycle is canceled.
