View abstract on PubMed
Summary
This summary is machine-generated.Assisted reproductive technology (ART) cycles and neonate numbers increased significantly in Japan in 2022, with expanded insurance coverage playing a key role. Live birth rates remained high for both fresh and frozen embryo transfers.
Area Of Science
- Reproductive Medicine
- Public Health
- Biostatistics
Background
- Assisted reproductive technology (ART) is crucial for addressing infertility.
- Understanding national ART trends is vital for policy and practice.
- Japan's ART registry provides comprehensive national data.
Purpose Of The Study
- To analyze the 2022 assisted reproductive technology (ART) data from the Japan Society of Obstetrics and Gynecology registry.
- To identify trends in ART cycles, outcomes, and patient demographics.
Main Methods
- Descriptive analysis of national ART registry data for 2022.
- Inclusion of data from 634 participating ART facilities.
- Analysis of cycle types, oocyte retrieval, embryo transfer, and neonatal outcomes.
Main Results
- A 9.1% increase in ART cycles and a 10.6% increase in neonates compared to the previous year.
- Freeze-all strategies were increasingly used in in vitro fertilization and intracytoplasmic sperm injection cycles.
- High singleton live birth rates were observed for both fresh (97.4%) and frozen-thawed embryo transfers (96.9%).
- A significant proportion of cycles (38.7%) were for women aged 40 years and older.
Conclusions
- The substantial growth in ART utilization and success rates in 2022 is linked to expanded insurance coverage.
- ART remains a vital option for a growing number of individuals, including older women.

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...
