Reproductive characteristics and steroid levels in the scleractinian coral Oculina patagonica inhabiting contaminated sites along the Israeli Mediterranean coast

► We followed gametogenesis and steroid hormone levels in corals from polluted sites. ► Evidence for accumulation of hormones was found in coral tissues in polluted sites. ► Corals exposed to acute pollution failed to complete gametogenesis. ► Corals exposed to chronic pollution did not show gametogenic disruption. ► Adaptation/physiological adjustment processes potentially enhance coral tolerance.
