I have done 2 split cycles at CNY. They only split two, not three. First cycle we each got 6 eggs, 5 fertilized, transferred 3 on day 5. Had twins. No frozens. Second split had 6 eggs, four fertilized, transferred 3 on day 3, got.pregnant with a singleton. M/c at 7 weeks. My first donor was 28 and proven, second donor 21 unproven. Her very next cycle she produced 11 blasts.2 tramsferred (twins) and 9 frozen. Her first cycle was not great, only one of.the other recp eggs fertilized. I cycled ay CNY for all.cycles.
