Definition En algunos juegos de naipes, falto de algún palo. Órgano que presenta el macho de los mamíferos, de forma eréctil, en el que desembocan los conductos del tracto genitourinario. En algunos animales se retrae en la ingle, y sólo se extiende durante la excreción y la cópula; en el ser humano no es retráctil. Está compuesto en su mayor parte por tejidos esponjosos, llamados cuerpos cavernosos, que al saturarse de sangre producen la erección.
