Pregnancy and birth after intracytoplasmic sperm injection of in vitro matured germinal-vesicle stage oocytes: case report.
OBJECTIVE
To report a normal pregnancy and the delivery of a healthy child after the combination of in vitro maturation of germinal-vesicle stage oocytes and intracytoplasmic sperm injection (ICSI) in a patient.


METHODS
Procedures were performed in a tertiary IVF center coupled with an institutional research environment.


METHODS
Maturation rate of immature oocytes after in vitro maturation and intactness, fertilization, and developmental rates of oocytes after microinjection.


RESULTS
Nine of 14 germinal-vesicle stage oocytes matured to the metaphase II stage after 30 hours of in vitro culture (64%). Seven of eight injected and intact oocytes fertilized normally (78%) and five of them cleaved with < 20% fragmentation (71%). Four embryos were transferred and a singleton pregnancy was obtained that ended in the delivery of a healthy child.


CONCLUSIONS
In vitro maturation of immature oocytes together with ICSI can result in normal fertilization, embryo development, pregnancy, and the delivery of healthy child.
