title: The couple's decision-making in IVF: one or two embryos at transfer?
abstract: BACKGROUND
  The aim of this study was to evaluate the decision-making process and factors that contribute to the decision of IVF participants to choose one or two embryos at transfer.
  
  
  METHODS
  Two hundred and seventy-four IVF patients equally distributed in males and females were personally interviewed using a semi-structured questionnaire which included 82 items.
  
  
  RESULTS
  In the whole study population, previous childbirth [odds ratio (OR) 2.1; 95% confidence interval (CI) 1.9-3.6], and spare embryos to freeze (OR 23.6; 95% CI 11.2-54.5) emerged as the most important variables in patients who had one embryo transferred, while previous IVF treatments (OR 0.3; 95% CI 0.1-0.6) and the assumed increased pregnancy chance (OR 0.1; 95% CI 0.05-0.3) were the most important decision-making factors among those who had two embryos. The women were more satisfied with the information (83 versus 71%; P = 0.02), and more aware of the risks with twin pregnancies (77 versus 66%; P = 0.03) than the males. The women were also more concerned about their age. Knowledge about risks of multiple pregnancies was higher in females (77%) than in males (66%, P = 0.03).
  
  
  CONCLUSIONS
  The results of this study indicate that despite good information about the risks for complications with multiple pregnancies, many patients wish to have two embryos transferred. Spare embryos to freeze, improvement of pregnancy rate in single embryo transfer and young age of the woman are predictive of choosing single embryo transfer. However, the final decision must always be made in agreement with the physician.
