2022 Final Assisted Reproductive Technology (ART) Success Rates

ART data are made available as part of the National ART Surveillance System (NASS) that collects success rates, services, profiles and annual summary data from fertility clinics across the U.S. There are four datasets available: ART Services and Profiles, ART Patient and Cycle Characteristics, ART Success Rates, and ART Summary. All four datasets may be linked by “ClinicID.” ClinicID is a unique identifier for each clinic that reported cycles. The Success Rates dataset contains success rates for ART cycles started during the year indicated. Since ART success depends on whether patients are using their own eggs or donor eggs, success rates are included separately for these two groups. Success rates for patients using their own eggs are shown per intended retrieval, per actual retrieval, and per transfer. These success rates are reported as cumulative success rates, which take into account transfers that occur within 1 year after an egg retrieval. Since ART success depends on whether patients are using ART for the first time or had prior ART cycles, users can examine success rates for all “Patients using their own eggs” or for “Patients with no prior ART using their own eggs.” For new patients using ART for the first time, the success rates are also shown after 1, 2, or all intended egg retrievals during the reporting year. In addition, the average number of transfers per intended retrieval and the average number of intended retrievals per live-birth delivery are shown. Success rates for ART cycles that involve the transfer of embryos created from donor eggs or donated embryos are shown and are not cumulative. They are based on donor cycles started in the year indicated that had embryo transfers, regardless of when the donor eggs were retrieved. Success rates in this section are not presented by patient age group because previous data show that an intended parent’s age does not substantially affect success when using donor eggs or donated embryos. The success rates are presented by types of embryos and eggs used in the transfer. This dataset excludes cycles that were considered research—that is, cycles performed to evaluate new procedures.辅助生殖技术（Assisted Reproductive Technology, ART）相关数据依托全美辅助生殖技术监测系统（National ART Surveillance System, NASS）对外发布，该系统负责收集美国境内各生殖诊所的成功率、服务项目、机构概况及年度汇总数据。本次公开的数据集共四类，分别为ART服务与概况数据集、ART患者及周期特征数据集、ART成功率数据集以及ART汇总数据集。四类数据集均可通过"ClinicID"进行关联，"ClinicID"为上报生殖周期的各诊所的唯一标识符。 ART成功率数据集包含对应年度内启动的ART辅助生殖周期的成功率数据。由于ART辅助生殖的成功率取决于患者使用自身卵子还是供体卵子，因此两类群体的成功率将分别统计。使用自身卵子的患者群体的成功率，将按预期取卵周期、实际取卵周期及胚胎移植周期分别展示。此类成功率为累积成功率，统计范围涵盖取卵后1年内开展的所有胚胎移植操作。 由于ART辅助生殖的成功率还与患者是否首次接受ART治疗或既往有ART周期史相关，用户可分别查询"使用自身卵子的全部患者"及"既往无ART治疗史且使用自身卵子的患者"的成功率数据。针对首次接受ART治疗的新患者，本次还将展示其在报告年度内完成1次、2次或全部预期取卵周期后的成功率数据。此外，数据集还将提供每预期取卵周期的平均移植次数，以及每活产分娩的平均预期取卵周期数。 涉及供体卵子或捐赠胚胎培育的胚胎移植的ART辅助生殖周期的成功率数据同样会展示，且此类数据不属于累积成功率范畴。该类成功率基于报告年度内启动且完成胚胎移植的供体周期计算，与供体卵子的取卵时间无关。本章节的成功率数据未按患者年龄组划分，既往研究数据显示，当使用供体卵子或捐赠胚胎时，意向父母的年龄对辅助生殖成功率无显著影响。该类成功率将按移植所用胚胎及卵子的类型进行分类展示。 本数据集排除了用于科研性质的辅助生殖周期，即用于评估新型诊疗技术的辅助生殖周期。
