title: Prognosis following in vitro fertilization-embryo transfer (IVF-ET) in patients with elevated day 2 or 3 serum follicle stimulating hormone (FSH) is better in younger vs older patients.
abstract: OBJECTIVE
  To determine if younger women with increased day 2 or 3 serum follicle stimulating hormone (FSH) levels have a better prognosis than older women with similar FSH elevations.
  
  
  METHODS
  Retrospective comparison of in vitro fertilization (IVF) outcome from cycles from 1/1/97 to 9/30/99 according to serum FSH < or = 12 vs > 12 and age < or = 38 or > 38. Only cycles where follicular phase leuprolide acetate was used were included.
  
  
  RESULTS
  Age group < or = 38 - clinical pregnancy rate (PR)/transfer was 32% with lower FSH vs 28.6% with higher FSH. The respective PRs for the older group were 30.3% and 5.5%.
  
  
  CONCLUSIONS
  Oocyte quality as evidenced by PRs following IVF-ET seems to be better in younger vs older patients despite increased basal serum FSH levels.
