PURPOSE: The Japan Society of Obstetrics and Gynecology started an online cycle-based assisted reproductive technology (ART) registry system in 2007. This report presents the characteristics and treatment outcomes of ART registered for the cycles practiced during 2016.
METHODS: Cycle-specific information for all ART cycles implemented in participating ART facilities were collected. A descriptive analysis was conducted for the registry database of 2016.
RESULTS: In total, 447 790 treatment cycles and 54 110 neonates (one in 18.1 neonates born in Japan) were reported in 2016. The mean patients' age was 38.1 years (SD = 4.5). Among the egg retrieval cycles, 104 575 of 251 399 (41.6%) were freeze-all cycles without fresh embryo transfers (ET), while fresh ET was performed in 64 497 cycles (58.4%). A total of 187 132 frozen-thawed ET cycles were reported, resulting in 62 432 pregnancies and 44 484 neonates born. Single ET was selected for 81.0% of fresh transfers and 82.7% of frozen cycles, resulting in singleton pregnancy/live birth rates of 97.0%/96.4% and 96.7%/96.4%, respectively.
CONCLUSION: The total ART cycles and subsequent live births continued to increase in 2016. Single ET was performed more than 80%, and ET has shifted from using fresh embryos to frozen ones.
