Retrieved 22 July 2013.A penis ( / ˈ p iː n ɪ s/; pl.: penises or penes) is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation. [1] [2] Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species. Furthermore, penises are not necessarily homologous. The penile morphology of some types of strepsirrhine primates has provided information about their taxonomy. [107] Male galago species possess very distinctive penile morphology that can be used to classify species. [108] [109] [110] Fedigan L, Fedigan LM (1988).
