What is your success rate, and what does that number mean?

Any single success rate is misleading. The two numbers that matter are the clinical pregnancy rate per embryo transfer (mostly determined by your embryos and your clinic) and the share of journeys that end with a baby (which includes rematches and additional transfers). We publish both, with the counts behind them. A "99% success" figure is a per-journey rate after unlimited attempts and says nothing about how many transfers it took.
