Infertility touches far more people than most realize, and the latest global estimates put the figure at about 1 in 6 couples. What stands out is how that burden does not fall evenly, with differences shaped by age, access to diagnosis, and where care is available. By comparing these patterns side by side, the statistics reveal surprising gaps that are easy to miss when you only see a single headline number.
