Assisted reproductive technologies (ART) in Canada: 2007 results from the Canadian ART Register

Area of Science:

• Reproductive Medicine
• Infertility Treatment
• Public Health Surveillance

Background:

• The Canadian ART Register (CARTR) has collected data on assisted reproductive technologies (ART) since its inception.
• Annual reporting is crucial for monitoring trends and outcomes in ART across Canada.

Purpose of the Study:

• To report on ART cycles performed in Canada during 2007.
• To analyze trends in ART outcomes, including pregnancy and live-birth rates, over time.

Main Methods:

• Prospective cohort study design.
• Data collected from all 26 ART centers in Canada.
• Analysis of in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and frozen embryo transfer (FET) cycles.

Main Results:

• 13,482 ART cycles were reported. For IVF/ICSI with own oocytes, live-birth rate was 28.6% per cycle started.
• IVF/ICSI with donor oocytes yielded a 36.1% live-birth rate.
• Frozen embryo transfer cycles resulted in a 17.8% live-birth rate, with decreasing high-order multiple births.

Conclusions:

• CARTR achieved 100% voluntary participation from Canadian ART centers for the fifth consecutive year.
• Clinical pregnancy and live-birth rates continued to increase in 2007 compared to previous years.
• A notable decrease in high-order multiple births was observed in 2007.
