O-123 Trends and challenges in the practice of ART in China

Abstract

Abstract China is a large country with a population of over 1.4 billion. In 1988, the first in-vitro fertilization-embryo transfer (IVF-ET) baby was born in Peking University Third Hospital. In the following 3 decades, assisted reproductive technology (ART) has developed rapidly in China, and the availability and accessibility of the ART service have improved markedly. In 2004 totally, only 37 institutions had passed the administrative licensing procedure to carry out ART. While in 2020, 536 institutions obtained the ART license. Since 2016, the total number of ART service cycles(Artificial insemination included)has exceeded 1 million, and the number of babies born has exceeded 300,000, accounting for about 2% of the total live births in China in 2016. At present, assisted reproductive technology has become one of the important medical interventions for the treatment of infertility in China, which has brought good news to infertile couples and their families, and has made great contributions to social harmony and family happiness. Cycles per million population (C/M) in 2009 was 120. In 2020, it has increased to 668, with more and more infertile couples having access to this technique in China. The success rate of assisted reproductive technology remained stable. In 2020, the clinical pregnancy rates (CPR)of conventional IVF and ICSI fresh embryo transfer cycles reached 52.4% and 49.4%, respectively, and the live birth rates were 43.0% and 40.6%, respectively. The clinical pregnancy rate and live birth rate of frozen-thawed embryo cycle were 51.3% and 40.5% per transfer. With the widespread application of embryo freezing technology, the cumulative live birth rate was estimated to reach 49.5% (CLBR estimate) in 2020. The safety monitoring indicators of assisted reproductive technology showed that since 2015, the multiple pregnancy rates of conventional IVF, ICSI and FET have decreased year by year, and have dropped to 22.4%, 21.4% and 17.6% in 2020, respectively. The incidence of moderate-severe ovarian hyper-stimulation syndrome (OHSS) and severe bleeding were also under control, within a reasonable range. Assisted reproductive technology, which involves many medical, social, ethical and legal issues, is a special clinical technology with limit application for medical indication. The Chinese government attaches great importance to the quality and safety management of assisted reproductive technology. A series of management documents such as the Administrative Measures for Human Assisted Reproductive Technology, the Regulations for Human Assisted Reproductive Technology and so forth, have been issued since 2001. Further improvement of key performance indicators (KPIs) correlated with ART quality and safety control is of the top priority and also challenging. In addition, the ART surveillance data in China is still aggregated data, which does not include important indicators such as age stratification, infertile factors or indications and delivery gestational age, maternal and infant outcomes, with some limitations for surveillance. Continuous improvement of data quality, and initiation of cycle-based data collection and security measures of case information are also challenging for the next step.
