RESUMO
Objective To investigate the difference in the outcome of ICSI-ET cycles among respondents patients, taking into account the molecule inducer of controlled ovarian stimulation: HP-hMG ou rFSH. Patients and Methods A comparative retrospective study over 62 months including a total of 1005 infertile couples, divided into two groups: HP-HMG (n=125) and rFSH (n=880). Results - The average numbers of retrieved oocytes and matures oocytes were significantly higher in rFSH group rFSH (7,94 ± 2,49, HP-HMG vs 9,05 ± 3,40, rFSH, p=0.0001and 3±2,68, HP-HMG vs 6,65±3,05 , rFSH, p=0,02 respectively). There was no statistically significant difference in the endometrial thickness and estradiol level on hCG injection day, the total amount of administrated gonadotropin and the duration of stimulation. In addition, we did not find a significant difference between the two groups regarding the fertilization, the maturation, the cleavage, top quality embryo, implantation, clinical pregnancy, multiple pregnancies, live birth and miscarriage rates. There was no case of severe ovarian hyperstimulation syndrome. Conclusion - Inspite of a higher number of retrieved and mature oocytes obtained with rFSH, the latter showed no superiority over HP-hMG which seem to be equally efficient and safe for ICSI treatment cycles.
