To present the success rates of assisted reproductive technology (ART) cycles performed in 2002 in Canada. This is the second annual report of Canadian ART outcomes.
Prospective cohort study.
Twenty-one of 22 ART centers in Canada.
PATIENT(S): Couples undergoing ART treatment in Canada during 2002.
INTERVENTION(S): Assisted reproductive technology treatments, including IVF, intracytoplasmic sperm injection (ICSI), frozen embryo transfer (FET), and oocyte donation.
MAIN OUTCOME MEASURE(S): Clinical pregnancy, live birth, and multiple birth rates.
RESULT(S): A total of 9,188 ART cycles was reported to the Canadian ART Register. There were 6,547 IVF/ICSI cycles using the woman's own oocytes. Per cycle started, the clinical pregnancy rate was 29.9% (36.0% per ET procedure) and the live birth rate was 23.8%; the multiple birth rate per delivery was 34.8%. Of cycles with oocytes retrieved, IVF was performed in 46% and ICSI in 54%; the outcomes were similar with the two procedures. There were 325 IVF/ICSI cycles using donor oocytes. The clinical pregnancy rate was 34.8% and the live birth rate was 24.6%; the multiple birth rate was 34.6%. There were 2,083 FET cycles using the woman's own oocytes. The clinical pregnancy rate was 20.9% and the live birth rate was 16.3%; the multiple birth rate was 25.2%.
CONCLUSION(S): For 2002, the Canadian ART Register achieved 95% voluntary participation from Canadian ART centers. Clinical pregnancy and live birth rates comparable to those of other countries were achieved. Success rates were higher in 2002 than in the previous year.
呈现2002年在加拿大进行的辅助生殖技术（ART）周期的成功率。这是加拿大ART结局的第二份年度报告。
前瞻性队列研究。
加拿大22个ART中心中的21个。
2002年在加拿大接受ART治疗的夫妇。
辅助生殖技术治疗，包括体外受精（IVF）、卵胞浆内单精子注射（ICSI）、冻融胚胎移植（FET）和卵子捐赠。
临床妊娠率、活产率和多胎出生率。
共有9188个ART周期上报至加拿大ART登记处。有6547个使用女性自身卵子的IVF/ICSI周期。每个开始的周期，临床妊娠率为29.9%（每次胚胎移植程序为36.0%），活产率为23.8%；每次分娩的多胎出生率为34.8%。在取卵的周期中，46%进行了IVF，54%进行了ICSI；两种程序的结局相似。有325个使用捐赠卵子的IVF/ICSI周期。临床妊娠率为34.8%，活产率为24.6%；多胎出生率为34.6%。有2083个使用女性自身卵子的FET周期。临床妊娠率为20.9%，活产率为16.3%；多胎出生率为25.2%。
2002年，加拿大ART登记处实现了加拿大ART中心95%的自愿参与。取得了与其他国家相当的临床妊娠率和活产率。2002年的成功率高于上一年。
