Cyphopods, also known as vulvae, are paired sacs in female millipedes that located on the underside of the third body segment that store sperm and connect to the oviduct.{{cite web|url=http://www.polydesmida.info/polydesmida/cyphopods.html|title=External Anatomy of Polydesmida: Cyphopods|work=polydesmida.info|first=Robert|last=Mesibov|authorlink=Robert Mesibov|access-date=2015-08-27|archive-url=https://web.archive.org/web/20150924075446/http://www.polydesmida.info/polydesmida/cyphopods.html|archive-date=2015-09-24|url-status=dead}} Cyphopods are sclerotized, and usually hidden behind a small opening. Despite the connotation of the suffix -pod (generally referring to legs or feet), cyphopods are not derived from walking legs.{{cite journal|last1=Hoffman|first1=Richard|authorlink1=Richard L.
