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.

  • Extend Fertility reports the higher IVF live-birth rate per intended egg retrieval for patients under 35 (47.6%).
  • Weill Cornell (Reproductive Medicine) reports the most IVF cycles (3,311 reported cycles), an honest proxy for scale, not a verdict on quality.
