title: High-order oocyte transfer in gamete intrafallopian transfer patients 40 or more years of age.
abstract: OBJECTIVE
  To analyze whether a policy of high-order oocyte transfer would be effective in women > or = 40 years of age who are undergoing GIFT, and further, whether a specific subgroup of these patients could be identified where clinical pregnancy was more likely to occur.
  
  
  METHODS
  Prospective descriptive study.
  
  
  METHODS
  Patients in a university-based reproductive endocrinology and infertility practice.
  
  
  METHODS
  Infertile women > or = 40 years of age who underwent GIFT cycles between January, 1990 and December, 1993 after not having achieved pregnancy with at least three previous cycles of superovulation and intrauterine insemination.
  
  
  METHODS
  Gamete intrafallopian transfer was performed after controlled ovarian hyperstimulation with hMGs. High-order oocyte transfer was employed.
  
  
  METHODS
  Clinical pregnancy rates (PRs).
  
  
  RESULTS
  The overall clinical PR was 24.5% per retrieval (12/49) and 25.5% per transfer (12/47). A significantly higher number of oocytes were retrieved in patients who became pregnant than those who did not. Patient age, cycle day 3 FSH level, E2 level on the day of hCG administration, number of oocytes transferred, and total number of motile sperm transferred did not differ significantly between the two groups. The clinical PR per transfer was significantly higher in patients with more than five oocytes transferred (10/27, 37%) versus those with five or less oocytes transferred (2/20, 10%). No multiple gestations were obtained.
  
  
  CONCLUSIONS
  The number of oocytes retrieved in women > or = 40 years of age undergoing GIFT is the main determinant predicting clinical pregnancy. High-order oocyte transfer seems to lead to a favorable PR while the risk of multiple gestation is limited.
