Abstract

Purpose: The Japan Society of Obstetrics and Gynecology (JSOG) registry gathers comprehensive data from registered assisted reproductive technology (ART) facilities in Japan. Herein, we report 2021 ART cycle characteristics and outcomes.

Methods: Descriptive statistics were used to summarize and analyze 2021 data.

Results: In 2021, 625 ART facilities participated in the registry; 27 facilities did not conduct ART cycles and 598 registered treatment cycles. In total, 498 140 cycles were registered, and there were 69 797 neonates (increases of 10.7% and 15.5%, respectively, from the previous year). The number of freeze-all in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles decreased in 2021; the number of neonates born was 2268 for IVF-embryo transfer (ET) cycles and 2850 for ICSI cycles. Frozen-thawed ET (FET) cycles increased markedly from 2020 (11.2% increase). In 2021, 239 428 FET cycles were conducted, resulting in 87 174 pregnancies and 64 679 neonates. For fresh transfers, the total single ET, singleton pregnancy rate, and singleton live birth rates were 82.7%, 97.0%, and 97.3%; for FET, these rates were 84.9%, 96.9%, and 97.1%.

Conclusions: The 2021 Japanese ART registry analysis showed marked increases in both total treatment cycles and live births from the previous year.

日本的辅助生殖技术：日本妇产科学会伦理委员会 2021 年总结报告。

目的：日本妇产科学会（JSOG）登记处收集了日本注册辅助生殖技术（ART）机构的全面数据。在此，我们报告了 2021 年 ART 周期的特征和结果：方法：采用描述性统计对 2021 年的数据进行总结和分析：2021年，共有625家ART机构参与登记；27家机构未开展ART周期，598家机构登记了治疗周期。共登记了 498 140 个周期，新生儿 69 797 例（分别比上一年增加 10.7% 和 15.5%）。2021 年，冷冻体外受精（IVF）和卵胞浆内单精子显微注射（ICSI）周期的数量有所减少；IVF-胚胎移植（ET）周期的新生儿出生人数为 2268 人，ICSI 周期的新生儿出生人数为 2850 人。冷冻-解冻胚胎移植（FET）周期比 2020 年明显增加（增加 11.2%）。2021 年，共进行了 239 428 个 FET 周期，结果有 87 174 例妊娠和 64 679 例新生儿。就新鲜移植而言，单次 ET、单胎妊娠率和单胎活产率分别为 82.7%、97.0% 和 97.3%；就 FET 而言，这些比率分别为 84.9%、96.9% 和 97.1%：2021 年日本抗逆转录病毒疗法登记分析显示，治疗周期总数和活产率均比上一年有显著增长。
