title: In vitro fertilization in a spontaneous cycle: a successful simple protocol.
abstract: OBJECTIVE
  To study the efficacy of a simple protocol of in vitro fertilization in the spontaneous natural cycle.
  
  
  METHODS
  A prospective study using in vitro fertilization in a natural cycle for the treatment of infertility due to tubal factor.
  
  
  RESULTS
  Fifty-eight patients were monitored by vaginal ultrasound and LH in urine for 229 cycles. In 49.8% of the cycles the pick-up was canceled because of the early LH rise or failure to visualize a dominant follicle. Ovum pick-up was performed in 112 cycles and oocyte retrieval rate was 87.5%. Embryo transfer was performed in 86 cycles, pregnancy rate per pick-up was 10.2%, and there was no pregnancy wastage.
  
  
  CONCLUSIONS
  IVF in a spontaneous cycle is a simple, low cost and safe treatment, which yields reasonable PR, for young regularly menstruating women with tubal factors of infertility.
