Clinical results are a mixture of:
‍
1) Success rates - the most unbiased way to measure clinical results and the effectiveness of a clinic - the rate of successful IVF (baby-making) cycles done by a clinic*. That being said, there is no public data on success rates for frozen eggs.
‍
2) the volume of egg-freezing cycles a clinic did, as it shows their experience with the technology.
‍
3) the embryology lab is a criterion of clinical results, but it is hard to quantify. It is important because, after the retrieval, your eggs will be analyzed by an embryologist who will select mature eggs and freeze them. A few things are essential here:
•  how advanced is the equipment used in the lab.
•  how qualified the embryologist is (years of experience and education).
