The male-female health survival paradox, also known as the morbidity-mortality paradox or gender paradox, is the phenomenon in which female humans experience more medical conditions and disability during their lives, but live longer than males.[2][3] The observation that females experience greater morbidity (diseases) but lower mortality (death) in comparison to males is paradoxical since it is expected that experiencing disease increases the likelihood of death.[2] However, in this case, the part of the population that experiences more disease and disability is the one that lives longer.
