Incazelo
Ukwengeza, ukuncishiswa kwe-sedimentation yesidoda kusiza ukugcina ikhwalithi nobuqotho be-spermatozoa, ukuqinisekisa ukusebenza kwabo ngesikhathi sokugcina isikhathi eside. Enqubweni yokukhiqiza, inhlanganisela yesidoda esinezikhwama kanye nobuchwepheshe bokumiswa kwembewu bungasetshenziswa ngempumelelo. Le nhlanganisela ingaveza izinzuzo ezibalulekile, njengezindleko ezincishisiwe zabasebenzi kanye nokusebenza kahle kokuzalanisa. Isidoda esifakwe esikhwameni singalengiswa kalula futhi sisetshenziswe ngesikhathi sokumiliswa, ukwenza inqubo ibe lula futhi kuncishiswe isikhathi nomzamo odingekayo. Idizayini ethambile neyisicaba yesikhwama sesidoda ithuthukisa futhi amandla okugcina isidoda. Ngokunciphisa ukucindezeleka esidodeni, isikhwama sivumela isidoda ukuba sigcine isimo saso semvelo kanye nesakhiwo, okuthuthukisa ukusinda. Lo mklamo uphinde unciphise ukucindezeleka esidodeni, okwandisa ukuhamba nokuqina. Ukunethezeka kungenye inzuzo enkulu yesidoda esifakwe esikhwameni.
Isikhwama sivulwa kalula ngokukhipha umlomo, okuvumela ukufinyelela okusheshayo nokuqondile esidodeni. Ukwengeza, isivalo esivulekile singasetshenziselwa ukuvala ukuvuleka kwesikhwama, ukuhlinzeka ngophawu oluhlanzekile noluvikelekile. Lesi sici esisebenzayo siqinisekisa ukuthi ikhwalithi yesidoda iyagcinwa ngaphambi nangemva kokumiliswa. Idizayini evamile ye-gradient yesikhwama sesidoda iqinisekisa ukuhambisana nawo wonke amadayamitha we-vas deferens ajwayelekile. Lokhu kuguquguquka kuvumela ukufakwa kalula kwe-vas deferens noma i-extension tube ngesikhathi sokumilisa, ukwenza inqubo ibe lula futhi kunciphise ithuba lephutha noma izinkinga. Sekukonke, isidoda esinesikhwama sinikeza izinzuzo eziningi ngaphezu kwesidoda esisebhodleleni. Ukuma kwayo okuyisicaba kukhuthaza ukuthintana kahle kwesidoda nesixazululo sezakhi, kunciphisa ukugcwala futhi kukhuthaze ukulondolozwa kwesidoda. Ihambisana nobuchwepheshe bokumiswa kwembewu, ukuthuthukisa ukusebenza kahle kokuzalanisa kanye nokunciphisa izindleko zabasebenzi. Idizayini ethambile neyisicaba yomzimba wesikhwama inciphisa ukucindezelwa kwesidoda futhi ithuthukisa izinga lokusinda lesidoda, futhi ukuba lula komlomo wesikhwama nesembozo kuthuthukisa ngokwengeziwe ukusebenziseka kwaso. Okokugcina, idizayini evamile ye-gradient iqinisekisa ukuhambisana nosayizi abahlukene be-vas deferens, ivumela ukuthi isetshenziswe ezimweni ezihlukahlukene zokuzalanisa.
