- Abstract
A prospective, randomized study was performed to compare the efficiency of hormonal stimulation for IVF (in vitro fertilization) in either the long luteal protocol, using the LHRH agonist Buserelin, or the multiple dose LHRH antagonist protocol, using the LHRH antagonist Cetrorelix. Here we present the data on the incidence of ovarian hyperstimulation syndromes (OHSS). 85 and 188 patients were recruited for the stimulation in the LHRH agonist and in the LHRH antagonist protocol, respectively. The groups were comparable regarding anamnestic data. The incidence of WHO degrees II and degrees III OHSS was significantly lower in the Cetrorelix than in the Buserelin group (1.1% vs. 6.5%, p=0.03). Additionally 3 patients in the Cetrorelix group (1.6%) and 5 patients in the Buserelin group (5.9%) did not receive hCG because of a threatening OHSS. The follicle maturation was more homogeneous in the Cetrorelix protocol, with less small follicles on the day of hCG administration but a similar number of oocyte cumulus complexes retrieved. The pregnancy rates per cycle were not significantly different in the Cetrorelix and Buserelin protocol (22% vs. 26%). The Cetrorelix multiple dose protocol is advantageous compared to the long protocol regarding the incidence of OHSS, a potentially life threatening complication of controlled ovarian stimulation.
