Pooled Prevalence of infertility
The pooled prevalence of infertility from a random-effects meta-analysis
of 27 studies was 12.87% (95% CI,12.41%-13.33%; \(I^{2}\)=99.98%)
(Figure 3A). The pooled prevalences of primary infertility and secondary
infertility were 7.34% (95% CI,3.65%-11.02%; \(I^{2}\)=99.76%) and
6.01% (95%CI,4.16%-7.85%; \(I^{2}\)=99.64%), respectively (Figure
3B).
