Experts estimate that approximately 1.7% of the population is born with intersex traits.
Notes on verification
Widely cited by UN OHCHR, Amnesty International, and CAP, but the figure originates from Fausto-Sterling's broad definition and is contested by researchers like Leonard Sax who argue a much lower prevalence (~0.018%) using stricter clinical definitions. The claim as stated is accurately attributed to 'experts' but the underlying statistic is scientifically debated.
