Incazelo
Iphakethe elivuleke kalula lingesinye isici esisebenzayo esengeza lula inqubo yokumila. Vele udabule iphakethe ukuze ufinyelele isidoda ngokushesha nangempumelelo. Isivalo esivulekile singasetshenziswa futhi ukumboza ukuvuleka kwesikhwama, ukugcina isidoda sihlanzekile futhi sinyumba kuze kube yilapho sesilungele ukusetshenziswa. Ukwengeza, idizayini evamile ye-gradient yesikhwama ivumela ukuhambisana nawo wonke amadayamitha we-vas deferens ajwayelekile. Lokhu kwenza inqubo yokuzalanisa ibe lula njengoba kungekho ukulungisa okwengeziwe noma ukuguqulwa okudingekayo, okunciphisa ubungozi bamaphutha noma izinkinga. Isikhwama sesidoda esiqhubekayo, esiklanyelwe ngokukhethekile ukulenga ukumilisa okuzenzakalelayo, singathuthukisa ukusebenza kahle futhi sisindise ukuzala. I-vas deferens ingafakwa kalula engulubeni ngezimbobo ezibekwe kahle emzimbeni wesikhwama. Uma sesifakiwe, isikhwama singalengiswa entanjeni ngaphezu kwengulube yengulube, kususwe isidingo sokugadwa njalo futhi kuvumele abasebenzi ukuthi benze eminye imisebenzi. Lesi sici sikhulisa kakhulu ukukhiqiza kwabasebenzi futhi senza inqubo yokumila ibe lula. Imvelo eyinyumba futhi engenalo uthuli yesikhwama sesidoda idlala indima ebalulekile ekuqinisekiseni ukuhlanzeka okuphelele kanye nekhwalithi yesidoda. Ngokunciphisa ithuba lokutheleleka, isikhwama sisiza ukugcina ubuqotho besidoda, okuthuthukisa izinga lokukhulelwa ezingulubeni.
Lesi sici sibaluleke kakhulu ngesikhathi sokuzala, njengoba noma yikuphi ukungcoliswa kungaba nomthelela omubi empumelelweni yokuzalanisa. Ekugcineni, isikhwama sesidoda esiqhubekayo samukela ukuklama kokuvula okuphezulu nezimbobo ezinhlangothini zombili, ezihambisana nokugcwalisa okuzenzakalelayo okuhlukahlukene kanye nemishini yokufaka uphawu ngesandla emhlabeni jikelele. Lokhu kuguquguquka kuvumela ukuhlanganiswa okungenamthungo ekusetheni okuhlukahlukene kokukhiqiza, okuqinisekisa ukusetshenziswa okuphelele nokuhambisana. Sekukonke, isidoda esifakwe esikhwameni sinezinzuzo eziningi, okuhlanganisa ukwakhiwa okuhlala isikhathi eside, ukufinyelela kalula, ukuhambisana nezinhlelo ezihlukahlukene, izinga eliphezulu lokuhlanzeka, ukusebenza kahle komsebenzi, kanye namazinga aphezulu okukhulelwa.
