['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.', '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.', '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%.'] Is prognosis following in vitro fertilization-embryo transfer ( IVF-ET ) in patients with elevated day 2 or 3 serum follicle stimulating hormone ( FSH ) better in younger vs older patients?
