Question special

I will help get us started with a question of my own. I noticed in the study design that the vast majority of patients received a day 3 transfer, but that a small portion received a day 5 transfer. I am curious how the authors decided to choose day 3 embryo transfer, and what the case was with small portion of patients receiving day 5 transfers. Was there any thought to using day 5 transfers in the PCOS population, with potentially lower egg quality, in order to allow additional time for the embryos to develop to select the highest quality embryo for transfer? Were you able to compare implantation and live birth rates between the day 3 and day 5 transfers or were the numbers too small for the day 5 group? I look forward to hearing your thoughts and to our continued discussion over the next 10 days!
