The World Health Organization (WHO) has released its first-ever global guideline on infertility, calling for safer, fairer, and more affordable fertility care for everyone. WHO estimates that one in six people of reproductive age will face infertility at some point, but in many countries, tests and treatments remain out of reach for all but the wealthiest, with costs that can overwhelm families—even a single round of IVF can cost twice an average household’s yearly income in some places.
