title: Comparison of serum and follicular fluid hormone levels with recombinant and urinary human chorionic gonadotropin during in vitro fertilization.
abstract: OBJECTIVE
  To study serum and follicular fluid (FF) hormone levels after the administration of urinary or recombinant hCG to initiate the final stages of oocyte maturation during IVF.
  
  
  METHODS
  Prospective randomized study between 250 microg of recombinant hCG and 7,500 IU of urinary hCG as the final trigger of ovulation during IVF.
  
  
  METHODS
  Private IVF center.
  
  
  METHODS
  Infertile women undergoing IVF/intracytoplasmic sperm injection (ICSI) using the long protocol and recombinant FSH.
  
  
  METHODS
  IVF treatment. Serum and FF hormone measurements on the day of oocyte collection.
  
  
  METHODS
  Serum and FF E(2), P, hCG, and T levels.
  
  
  RESULTS
  Stimulation parameters, serum and follicular E(2), P, T, and hCG levels were similar in the recombinant and urinary hCG groups. The number of oocytes retrieved from follicles >14 mm, the proportion of mature oocytes, fertilization rate, and pregnancy rate (PR) were also comparable.
  
  
  CONCLUSIONS
  Recombinant and urinary hCG provided similar serum and follicular hormonal environments during the final stages of oocyte maturation. The IVF outcome parameters were also comparable. The two medications appear to be equally effective.
