title: Intracytoplasmic sperm injection versus in vitro fertilization for patients with a tubal factor as their sole cause of infertility: a prospective, randomized trial.
abstract: OBJECTIVE
  To compare the efficacy of intracytoplasmic sperm injection and IVF in women with a tuboperitoneal factor as their sole cause of infertility.
  
  
  METHODS
  Prospective, randomized study.
  
  
  METHODS
  Hacettepe University Assisted Reproduction Unit, Ankara, Turkey.
  
  
  METHODS
  Seventy-six consecutively seen patients with tuboperitoneal factor infertility were randomized on an alternate basis to undergo either intracytoplasmic sperm injection (38 patients and cycles) or IVF (38 patients and cycles).
  
  
  METHODS
  Intracytoplasmic sperm injection and IVF.
  
  
  METHODS
  Fertilization, implantation, and clinical pregnancy rates.
  
  
  RESULTS
  A comparable number of oocytes and embryos were obtained with intracytoplasmic sperm injection and IVF. The two-pronuclei fertilization rates per metaphase II oocyte or mature cumulus-oocyte complex were similar in the two groups. The numbers of total and grade I embryos transferred also were similar. Comparisons of intracytoplasmic sperm injection and IVF did not reveal any statistically significant differences in individual implantation rates (38.75% +/- 24.46% and 34.58% +/- 16.97%, respectively) clinical pregnancy rates per cycle (21.05% and 21.05%, respectively), or take-home infant rates (18.42% and 15.79%, respectively). The type of procedure performed was not a significant predictor of clinical pregnancy.
  
  
  CONCLUSIONS
  When a decision is made to proceed with an assisted reproductive technique in patients with a tubal factor as their sole cause of infertility, IVF should be the initial treatment of choice.
