Abstract/OtherAbstract:
OBJECTIVE: Follow-up of IVF/intracytoplasmic sperm injection (ICSI) patients to obtain accurate information concerning chances of live birth as well as early treatment dropout. Comparison of the cumulative pregnancy rates, established in cohorts, with those estimated with life table analysis to determine which method provides the most accurate data without overestimation. DESIGN: Retrospective longitudinal cohort study. SETTING: Academic medical IVF center. PATIENT(S): All 750 patients from the Leiden IVF center and another 706 patients from cooperating clinics starting IVF/ICSI treatment in the period 1996-2000. INTERVENTION(S): All observations were part of standard IVF/ICSI and cryopreservation protocols. MAIN OUTCOME MEASURE(S): Endpoints of this study were a first live birth or termination of treatment. Treatment cycles were followed until the end of 2002, pregnancy follow-up through September 2003. RESULT(S): The cumulative live birth rate for the Leiden cohort was 59.1%. In yearly cohorts this varied from 54.8% to 67.1%. Cumulative live birth rates were 61.8%-63.2% for unexplained infertility (n = 229), endometriosis (n = 19), and andrologic indication (n = 223). For tubal (n = 129) and hormonal (n = 46) indications the rates were 55.8% and 45.7%, respectively. The group of egg donation or surrogacy (n = 10) reached 40.0%, and patients with two or more indications (n = 84) 56.0%. For women < or = 35 years of age the cumulative live birth rate was 64.6%, for women 36-39 years of age it was 48.7%, and for women 40-42 years of age 31.0%. CONCLUSION(S): In contrast to estimation of expected cumulative pregnancy rates the cohort measurement does not overestimate success rates. It accurately reflects chances of both live birth as well as early treatment dropout. The cumulative live birth rate was 59.1%. Over time results improved and the contribution of cryopreservation increased.
