title: Effect of highly purified urinary follicle-stimulating hormone on oocyte and embryo quality.
abstract: OBJECTIVE
  To determine the effects of ovarian stimulation with highly purified urofollitropin on oocyte and embryo quality.
  
  
  METHODS
  Parallel randomized open-label clinical study.
  
  
  METHODS
  Assisted reproduction centers.
  
  
  METHODS
  Two hundred sixty-seven infertile couples undergoing IVF/ICSI.
  
  
  METHODS
  All participants underwent standard down-regulation with GnRH analogue. One hundred thirty-three participants received highly purified urinary FSH and 134 controls received recombinant FSH.
  
  
  METHODS
  Primary end points were number of morphologically mature oocytes retrieved, embryo quality, and pregnancy and implantation rates. Secondary end points were: total number of days of FSH stimulation, total dose of gonadotropin administered, fertilization rate per number of retrieved oocytes, embryo cleavage rate, live birth and miscarriage rates, endometrial thickness and estradiol level on the day of hCG administration, cancellation rate, and incidence of moderate or severe ovarian hyperstimulation syndrome.
  
  
  RESULTS
  Pregnancy and implantation rates were nonsignificantly higher in the urinary FSH group than the recombinant FSH group (46.5% vs. 36.8% and 22.1% vs. 15.8%, respectively). The grade 1 embryo score was significantly higher in the urinary FSH group than the recombinant FSH (42.1% vs. 33.5%), and the live birth rate was nonsignificantly higher in the former group.
  
  
  CONCLUSIONS
  Highly purified urinary FSH is as effective, efficient, and safe for clinical use as recombinant FSH.
