The Short Version
Overwhelming medical evidence directly contradicts this claim. The World Health Organization, systematic reviews, and large cohort studies all confirm that oral contraceptive use — regardless of duration — does not cause long-term or permanent infertility, with fertility returning promptly after discontinuation. Some women may experience temporary cycle irregularity, but this is a short-term adjustment, not infertility. The sources cited in support of the claim are either low-authority, commercially conflicted, or internally self-contradictory.
