A historical review of the SART registry therefore is timely. The registry was established voluntarily in 1988. Several wide-ranging goals were established by SART. It was important for SART to accumulate the following information: IVF indication(s); number of IVF cycles and IVF-related procedures; ovulation induction protocols used, effectiveness of those protocols, and patient response; number of oocytes recovered and quality assessment; fertilization rate and incidence of polyspermia; embryo quality and embryonic arrests; number of embryos transferred (ET) and cryopreserved; pregnancy rate (PR) and outcome; number of implantation sacs per ET; number of multiple pregnancies; prevalence of fetal demise (spontaneous fetal resorption, miscarriage, stillbirth); and number of deliveries (at term, premature, multiple pregnancies).
