Abstract:

The aim of this study was to identify factors that inhibit or promote the adoption of single embryo transfer (SET). A cohort of 163 women patients receiving IVF/intracytoplasmic sperm injection treatment, comprising 87 women choosing SET and 63 women choosing double embryo transfer (DET), were interviewed using a structured questionnaire. The data were compared using logistic regression analysis. Confidence in the chance of pregnancy with SET, younger age and first treatment were predictive of a decision for SET. Preference for a healthy and singleton pregnancy was predictive but perceptions of the incidence or risk of multiple gestation were not. Factors such as a sense of time urgency and past experience of treatment were significant and predictive of diminished choice of SET. The clinic doctor was an important influencing factor. The results of this study confirm that improved pregnancy rates in SET coupled with an official clinic policy to promote SET in younger, first cycle patients influenced many women to choose SET. However, repeated treatment, advancing age and urgency to become pregnant are factors that moderate a woman's choice for SET.
