To transfer male reproductive cells from one individual to another, usually into an internal organ or cavity, such as a cloaca. Copulatory organs of eight species of the monophyletic taxon Childia were investigated in detail, using phalloidin fluorescence method and confocal microscopy. Childia species were shown to have one, two or several tubular stylets, conical to cylindrical in shape, composed of few to numerous needles.

Intromittent organs are found most often in terrestrial species, as most non-mammalian aquatic species fertilize their eggs externally, although there are exceptions. For many species in the animal kingdom, the male intromittent organ is a hallmark characteristic of internal fertilization. The copulative organ Contrary to the rooster, Gallus gallus, the copulatory organ of the gander is very well developed. It is invaginated, spiral-like and is about 15 cm in length.
