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.
