Purpose: To evaluate clinical outcomes after endometrial receptivity analysis (ERA).
Methods: This was a multicenter, retrospective cohort study involving 861 women who underwent ERA testing at certified fertility clinics in Japan, and who received subsequent personalized blastocyst embryo transfers (ET) between 2018 and 2020. Clinical outcomes, including pregnancies, miscarriages, and live births, were evaluated according to receptivity status for ERA.
To investigate the impact of a state of emergency (i.e., voluntary lockdown) during the COVID-19 epidemic, we conducted a retrospective cohort study using the Japanese nationwide registry.

Purpose: Since 1986, the Japan Society of Obstetrics and Gynecology assisted reproductive technology (ART) registry system has collected data on national ART use and outcomes trends in Japan. Herein, we describe the characteristics and outcomes of ART cycles registered during 2020 and compare the results with those from 2019.
Methods And Results: In 2020, 621 ART facilities participated in the registration.
Article Synopsis
- The Japan Society of Obstetrics and Gynecology provided data on assisted reproductive technology (ART) cycles for 2019, showing a trend of decreased fresh cycles and increased frozen-thawed embryo transfers.
- In total, there were over 458,000 treatment cycles and nearly 61,000 neonates, indicating growth from the previous year.
- The average maternal age was 37.9 years, and single embryo transfers were predominant, boasting a high live birth rate of 97.3%.
Purpose: We investigated the cumulative live birth rate (CLBR) in women receiving governmental subsidies for assisted reproductive technology (ART) in Saitama Prefecture, Japan.
Methods: Women who applied for subsidies from Saitama Prefectural Government for the first time in 2016 were enrolled and followed up until the end of 2017. Treatment information, including live birth, was obtained from the Japanese ART registry by linking it with unique identification numbers for treatment.
Purpose: Since 2007, the Japan Society of Obstetrics and Gynecology (JSOG) has collected cycle-based data for assisted reproductive technology (ART) in an online registry. Here, we present the characteristics and treatment outcomes of ART cycles registered during 2018.
Methods: The Japanese ART registry consists of cycle-specific information for all ART treatment cycles implemented at 621 participating facilities.
Purpose: The Japan Society of Obstetrics and Gynecology (JSOG) has collected cycle-based assisted reproductive technology (ART) data in an online registry since 2007. Herein, we present the characteristics and treatment outcomes of ART cycles registered during 2017.
Methods: We collected cycle-specific information for all ART cycles implemented at participating facilities and performed descriptive analysis.

Article Synopsis
- The Japan Society of Obstetrics and Gynecology launched an online ART registry in 2007, and this report focuses on the characteristics and outcomes of ART cycles from 2016.
- In 2016, there were 447,790 treatment cycles, resulting in 54,110 neonates born, with the average patient age at 38.1 years.
- The study found that a significant portion of egg retrievals were freeze-all cycles, and most embryo transfers were single transfers, contributing to high live birth rates for both fresh and frozen cycles.
Article Synopsis
- HMGN5 is a non-histone protein that binds to nucleosomes and is thought to be involved in mouse endometrial decidualization, though its specific function in human endometrial stromal cells (HESCs) is not fully understood.
- In experiments, HESCs treated with 8-br-cAMP and MPA showed a significant decrease in HMGN5 expression, and using siRNA to inhibit HMGN5 increased the expression of key decidual marker genes.
- The research indicates that lower levels of HMGN5 promote decidualization in HESCs and suggest it might regulate the microRNA miR-542-3p during this process.
Purpose: The Japan Society of Obstetrics and Gynecology (JSOG) implemented an assisted reproductive technology (ART) registry system in 1986. Here are reported the characteristics and treatment outcomes of ART cycles that were registered in 2015.
Methods: JSOG has requested all participating ART facilities to register cycle-specific information for all ART cycles since 2007.

Aim: The Japan Society of Obstetrics and Gynecology implemented a registry report system for the clinical practice of assisted reproductive technology in 1986. The aggregated results from 1992 to 2014 are reported herein.
Methods And Results: The total number of registered treatments was 393 745 cycles, of which 66 550 were pregnancy cycles and 46 008 were cycles with a live birth.
