Women aged 35- 37 years undergoing IVF- ET with fresh embryos at a university infertility center were analyzed to evaluate factors useful in determining whether two or three embryos should be transferred in this age group. Embryo quality and number, but not number of previous failed cycles, were important in determining outcome, and all triplet pregnancies could have been avoided at our program in this age group by limiting the transfer to two good- quality embryos, without reducing pregnancy rates.
