Side-by-Side Comparison
| Feature | fallo | falo |
|---|---|---|
| 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. |
