Preferences of subfertile women regarding elective single embryo transfer: additional in vitro fertilization cycles are acceptable, lower pregnancy rates are not.
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.
