title: Cost-effectiveness of IVF in women 38 years and older.
abstract: OBJECTIVE
  To compare the cost per delivery in women younger than 38 years with women equal to or older than 38 years of age attempting IVF.
  
  
  METHODS
  All couples undergoing IVF treatment between October 1991 and September 1998 were enrolled in this study. A standard protocol of controlled ovarian hyperstimulation was employed throughout the study. Four hundred and seven cases were allocated to two groups - group I composed of patients younger than 38 years of age and group II of patient equal to or older than 38 years of age. The total cost of each successful outcome was the goal of our study.
  
  
  RESULTS
  A total of 407 women underwent 722 stimulated cycles for IVF of which 122 cycles (16.89%) did not proceed to oocyte retrieval. We found statistically significant differences in the cancellation rate, the number of hMG ampoules, the number of oocytes retrieved, the number of oocytes fertilized, the number of embryos transferred, the clinical pregnancy rate, the rate of multiple pregnancy, the delivery per initiated cycle and the cost per delivery between the two groups (P<0.05, significant). The cost per delivery in group II was approximately 3.6 times that of group I.
  
  
  CONCLUSIONS
  Women age 38 years or more have less chance of a successful outcome from IVF treatment. Couples contemplating IVF should be provided with accurate information about prognosis for the pregnancy and the financial costs.
