title: Cross-over trial of superovulation protocols from two major in vitro fertilization centers.
abstract: A study was undertaken as a controlled comparison of two different superovulation induction protocols currently in use in major Australian in vitro fertilization (IVF) clinics. Thirty patients each from the Monash University and the Royal Women's Hospital (RWH) IVF programs were stimulated for ovulation induction by the other program. Once timing for oocyte retrieval was scheduled, all care reverted to the program from which the patient first came. Results given as pregnancies per patient commencing stimulation were: RWH patients on Monash protocol, 27%; RWH control patients, 15%; Monash patients on RWH protocol, 7%; Monash control patients, 13%. In the year preceding the trial pregnancy rates were 16.9% at Monash and 10.6% at RWH. Stimulation protocols were also compared with respect to each of administration, cost, and patient stress. The results of this cross-over trial demonstrated major differences between the two ovulation induction protocols studied, although it was not possible to conclude that differences in pregnancy rate were due to stimulation alone.
