Conclusion
The findings from this study may provide crucial data for use in future
research and clinical practice. Our study shows that the community-based
global prevalence of infertility was 12.87% and that infertility was
generally more common in persons who were from Africa or Oceania and in
women aged 35 and above. An upward trend of the prevalence of
infertility during the past 7 decades was observed and may persist in
the future. More high-quality epidemiologic investigations on
community-based infertility appear to be needed, especially for
different subgroups of infertility and within the Region of the
Americas, and the Region of Asia.
