title: Preferences of subfertile women regarding elective single embryo transfer: additional in vitro fertilization cycles are acceptable, lower pregnancy rates are not.
abstract: With identical pregnancy rates after elective single embryo transfer (ET) and double ET strategies consisting of three cycles of IVF or intracytoplasmic sperm injection (ICSI) plus transfers of thawed/frozen embryos if available, 46% of the women undergoing IVF/ICSI favor elective single ET. If elective single ET lowers pregnancy chances with 1%, 3%, or 5%, the percentage of women preferring elective single ET drops to 34%, 24%, and 15%, respectively. If four, five, or six cycles with elective single ET are needed to match the success rate of three cycles with double ET, the percentage of women with a preference for elective single ET drops from 46% to 40%, 36%, and 35% respectively.
