Abstract

Purpose: This descriptive analysis evaluated the 2022 assisted reproductive technology (ART) data collected by the Japan Society of Obstetrics and Gynecology registry.

Methods and results: In 2022 (cutoff date 30 November 2023), 634 of 635 registered ART facilities participated; 602 implemented ART treatment, with 543 630 registered cycles and 77 206 neonates (9.1% and 10.6% increases from the previous year). For fresh cycles, freeze-all in vitro fertilization and intracytoplasmic sperm injection cycles increased, resulting in 2183 and 2822 neonates, respectively. In total, 275 296 cycles resulted in oocyte retrieval, with 158 247 (57.5%) freeze-all cycles. Total single embryo transfer (ET) and singleton pregnancy rates were 82.4% and 97.2%, respectively. The singleton live birth rate was 97.4%. The number of frozen-thawed ET (FET) cycles was 264 412, with 98 348 pregnancies and 72 201 neonates. The single ET rate was 85.3%. The rate of singleton pregnancies was 96.9%; that of singleton live births was 96.9%. Per registered cycle, women had a mean age of 37.6 (standard deviation: 4.8) years; 210 322 cycles (38.7%) were conducted for women aged ≥40 years.

Conclusions: Significant growth in ART cycles and outcomes reflects the impact of recent expanded insurance coverage.

日本的辅助生殖技术：日本妇产科学会伦理委员会 2022 年总结报告。

目的：本描述性分析评估了日本妇产科学会登记处收集的2022年辅助生殖技术（ART）数据。方法与结果：2022年（截止日期2023年11月30日），635家注册ART机构中有634家参与；602个国家实施了抗逆转录病毒治疗，登记周期为543 630个，新生儿为77 206个（比上年分别增加9.1%和10.6%）。对于新鲜周期，冷冻全体外受精和卵浆内单精子注射周期增加，分别产生2183和2822个新生儿。总共有275 296个周期获得卵母细胞，其中158 247个（57.5%）全部冻结。总单胎移植率和单胎妊娠率分别为82.4%和97.2%。单胎活产率为97.4%。冻融ET （FET）周期264 412次，妊娠98 348例，新生儿72 201例。单次ET率为85.3%。单胎妊娠率为96.9%；单胎活产率为96.9%。每个登记周期，女性的平均年龄为37.6岁（标准差：4.8岁）；年龄≥40岁的女性进行了210322个周期（38.7%）。结论：ART周期和结果的显著增长反映了最近扩大保险覆盖范围的影响。
