The sex organs of a green alga Chara are the male antheridia (red) and female archegonia (brown).

Un órgano sexual ou órnao reprodutor é calquera parte anatómica do corpo dun organismo complexo que participa na reprodución sexual e que xuntos constitúen o sistema reprodutor. Os órganos visibles externos, en machos e femias, son os órganos sexuais primarios coñecidos como xenitais. Os órganos internos coñecidos como órganos sexuais secundarios[1][2] e son chamados ás veces como xenitais internos. As características que comezan a aparecer durante a puberty, such as, in humans, pubic hair on both sexes and facial hair on the male, are known as secondary sex characteristics.

Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte.[3] The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule.[4] Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen. The cones and pollen are not themselves sexual organs.
