RESUMO
Background: IVF is now a wide spread procedure globally, and currently 65 countries report annually all or part of their IVF/ICSI cycles, from which the International Committee Monitoring progress in Assisted Reproduction Technology (ICMART) published its report. There is considerable variation in the utilization (number of cycles per population) globally. Aims: The objectives of this study were to assess whether utilization is related to national wealth, presented as gross domestic product (GDP), and whether the GDP has any effect on success in IVF treatment, mainly delivery and clinical pregnancy rates. Results: The results demonstrated a significant positive correlation between utilization and GDP (CC = 0.563, p = 0.00000194), and both utilization and GDP have strong negative correlations to successful outcome of the treatment-clinical pregnancy rate (CC: -0.460, p = 0.00015; CC: -0.399, p = 0.0012, respectively) and delivery rates (cc = -0.396, p = 0.00484; cc = -0.3, p = 0.0179, respectively). Conclusions: Poor nations have less utilization of IVF, probably due to the limited affordability of the treatment, but reassuringly do not seem to have less success in the treatment. Further research is required to fully understand the implications of these correlations and to better design national and international fertility policies.
