title: Cycle 1 as predictor of assisted reproductive technology treatment outcome over multiple cycles: an analysis of linked cycles from the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System online database.
abstract: OBJECTIVE
  To determine whether the first cycle of assisted reproductive technology (ART) predicts treatment course and outcome.
  
  
  METHODS
  Retrospective study of linked cycles.
  
  
  METHODS
  Society for Assisted Reproductive Technology Clinic Outcome Reporting System database.
  
  
  METHODS
  A total of 6,352 ART patients residing or treated in Massachusetts with first treatment cycle in 2004-2005 using fresh, autologous oocytes and no prior ART. Women were categorized by first cycle as follows: Group I, no retrieval; Group II, retrieval, no transfer; Group III, transfer, no embryo cryopreservation; Group IV, transfer plus cryopreservation; and Group V, all embryos cryopreserved.
  
  
  METHODS
  None.
  
  
  METHODS
  Cumulative live-birth delivery per woman, use of donor eggs, intracytoplasmic sperm injection (ICSI), or frozen embryo transfers (FET).
  
  
  RESULTS
  Groups differed in age, baseline FSH level, prior gravidity, diagnosis, and failure to return for Cycle 2. Live-birth delivery per woman for groups I through V for women with no delivery in Cycle I were 32.1%, 35.9%, 40.1%, 53.4%, and 51.3%, respectively. Groups I and II were more likely to subsequently use donor eggs (14.5% and 10.9%). Group II had the highest use of ICSI (73.3%); Group III had the lowest use of FET (8.9%).
  
  
  CONCLUSIONS
  Course of treatment in the first ART cycle is related to different cumulative live-birth delivery rates and eventual use of donor egg, ICSI, and FET.
