Published prices can cover retrieval alone, a transfer, or a larger package. Open each network’s price details to compare the locations, inclusions and exclusions. We cannot identify a cheaper clinic from these different packages.
Success rates use patients’ own eggs and the same per-intended-retrieval denominator. An unreported retrieval rate stays blank. A check marks the higher reported figure for the selected age band. A higher success rate can reflect a clinic's case mix as much as its lab, so these are facts, not a recommendation: the right choice depends on your diagnosis, your insurance, and your clinician.
