ANZARD annual report on assisted reproductive technology activity, outcomes, and safety across Australia and New Zealand for 2023. Covers fresh-cycle and FET cycle counts, single-embryo transfer rates, clinical pregnancy and live birth rates, ART-conceived births, multiple pregnancy rates, and patient demographics. Published by the National Perinatal Epidemiology and Statistics Unit (NPESU) at UNSW Sydney with data submitted from all RTAC-accredited ART units in Australia and New Zealand.

To summarize assisted reproductive technology (ART) data for 2023 collected through the Japan Society of Obstetrics and Gynecology registry. 625 out of 638 registered ART facilities took part in the study, documenting 561 664 treatment cycles and 85 048 newborns (+3.3% and +10.2% increases from 2022). The average age of women undergoing treatment was 37.3 years (standard deviation: 4.8); 205 986 cycles (36.7%) involved women aged ≥ 40 years. Among fresh cycles, oocyte retrieval was performed in 281 665 cycles, including 168 343 freeze-all cycles (59.8%). A total of 2329 pregnancies and 3375 newborns resulted from in vitro fertilization and intracytoplasmic sperm injection cycles, yielding 1772 and 2502 newborns, respectively. The overall rates for single embryo transfer (SET) and singleton delivery were 80.5% and 96.5%. Frozen-thawed embryo transfer accounted for 271 361 cycles, resulting in 109 850 pregnancies and 80 774 newborns, with a SET rate of 84.7% and a singleton delivery rate of 96.3%. In 2023, the second year of insurance coverage, the registry recorded the highest numbers of treatment cycles and newborns. Effective registry systems planned for 2026 will enable comprehensive evaluation of emerging trends in Japanese ART practice.

What are the trends and effects of assisted reproductive technology (ART) interventions on the effectiveness and safety of ART carried out in Latin America during 2022. Retrospective collection of cycle-based multinational data obtained from ART procedures carried out by 204 accredited institutions in 16 countries. In total 123,265 initiated cycles resulted in 19,663 deliveries and 22,203 births. Use of ART varied greatly, from 643.3 cycles/million inhabitants in Uruguay to 28.8 in Guatemala. In autologous cycles, the proportion of women aged ≥40 years represents 35.1% of cycles, whereas women <34 years represents only 18.8%. The proportion of single embryo transfers (SET) increased from 42.4% in 2021 to 47.3% in 2022. Out of 22,203 babies born, 77.4% were singletons, 21.7% twins and 0.9% triplets or more. Intracytoplasmic sperm injection represented 85.4% of fertilization techniques, and blastocyst transfer increased from 79.3% in 2021 to 85.3% in 2022. Delivery rate after fresh blastocyst elective single embryo transfer (32.6%) was significantly higher than after the transfer of one frozen embryo transfer (FET) from freeze-all cycle (25.2%) (P = 0.0001). The number of aspirations leading to preimplantation genetic testing increased 2.6 times in 6 years, and significantly increased delivery rates/transfer (P ≤ 0.008) and reduced miscarriage at all ages (P ≤ 0.004) in autologous cycles, but not in oocyte donation cycles. Delivery rates after fresh transfer of embryos from vitrified-warmed donated oocytes, generated similar outcome to FET from fresh oocyte donation cycles (P = 0.5621). Perinatal mortality increased from 7.5‰ in singletons to 22.8‰ in twins. Systematic collection of cycle-based multinational data contributes to cooperative sustained development and helps implement evidence-based reproductive decisions.
