ABSTRACT
The use of ovarian stimulation has provided a means of obtaining multiple oocytes per assisted reproductive technology (ART) treatment cycle. In most cases the majority of oocytes retrieved will be successfully fertilized, and as a result, several embryos are typically available for transfer. Because the probability of an individual embryo forming a viable pregnancy is relatively low (approximately 15%) it has long been standard practice to transfer more than one embryo per cycle. This approach has been highly successful at increasing take-home-baby rates, thus reducing the likelihood that a patient will need to face the emotional, physical, and financial burden of multiple treatment cycles.
