title: Efficacy of a combined protocol of urinary and recombinant follicle-stimulating hormone used for ovarian stimulation of patients undergoing ICSI cycle.
abstract: OBJECTIVE
  To evaluate the efficacy of using both urinary and recombinant FSH in a combined protocol for ovarian stimulation in an IVF treatment program.
  
  
  METHODS
  A total of 119 infertile couples undergoing ICSI treatment were randomized prospectively in this study. After a standard down-regulation with GnRH analogue, the patients were randomized in 2 groups 58 received combined urinary and recombinant FSH, starting with uFSH and then rFSH, and 61 controls received only recombinant FSH.
  
  
  RESULTS
  Pregnancy and implantation rates were significantly higher in the combined uFSH/rFSH group than the control (rFSH) group (43.9% vs 22.1% and 27.5% vs 13.2% respectively). Metaphase II oocyte and grade 1 embryos were significantly higher in favour of combined uFSH/rFSH group than the recombinant FSH group.
  
  
  CONCLUSIONS
  This study shows that using a combination of both urinary and recombinant FSH for ovarian stimulation improves oocyte maturity and embryo cleavage, and increases pregnancy and implantation rates.
