Kufotokozera
Thumba losavuta lotseguka ndi chinthu china chothandiza chomwe chimapangitsa kuti umuna ukhale wosavuta. Ingong'ambani m'thumba kuti mupeze umuna mwachangu komanso moyenera. Chivundikiro chotsegulacho chingagwiritsidwenso ntchito kuphimba potsegula thumba, kusunga umuna waukhondo komanso wosabala mpaka utakonzeka kugwiritsidwa ntchito. Kuphatikiza apo, kapangidwe kachikwama kameneka kamalola kuti azigwirizana ndi ma diameter onse a vas deferens. Izi zimachepetsa njira yobereketsa chifukwa palibe kusintha kwina kapena kusintha komwe kumafunikira, kuchepetsa chiopsezo cha zolakwika kapena zovuta. Thumba losalekeza la umuna, lopangidwa mwapadera kuti lizipachika panjira yobereketsa, limatha kupititsa patsogolo ntchito yabwino ndikupulumutsa ntchito. Ma vas deferens amatha kulowetsedwa mu nkhumba mosavuta kudzera mabowo oyikidwa bwino m'thumba. Akalowetsa, thumba likhoza kupachikidwa pa chingwe pamwamba pa nkhumba, kuchotsa kufunika koyang'anira nthawi zonse ndi kulola ogwira ntchito kugwira ntchito zina. Izi zimakulitsa kwambiri zokolola za ogwira ntchito komanso zimathandizira njira yobereketsa. Kusabereka komanso kopanda fumbi kwa thumba la umuna kumapangitsa kuti umuna ukhale waukhondo. Pochepetsa mwayi woipitsidwa, thumba limathandizira kusunga umphumphu wa umuna, zomwe zimapangitsa kuti mimba ikhale yabwino.
Izi ndizofunikira makamaka pakubereka, chifukwa kuipitsidwa kulikonse kumatha kusokoneza kupambana kwa ubwamuna. Pomaliza, thumba la umuna lomwe limapitilira limatengera mapangidwe otsegulira kumtunda ndi mabowo mbali zonse ziwiri, zomwe zimagwirizana ndi makina osiyanasiyana odzaza okha komanso osindikiza pamanja padziko lonse lapansi. Kusinthasintha kumeneku kumapangitsa kusakanikirana kosasunthika m'mapangidwe osiyanasiyana opanga, kuwonetsetsa kugwiritsa ntchito bwino komanso kugwirizanitsa. Ponseponse, umuna wonyamula m'matumba uli ndi zabwino zambiri, kuphatikiza kumanga kolimba, kupezeka kosavuta, kugwirizana ndi machitidwe osiyanasiyana, ukhondo wapamwamba, kugwira ntchito bwino, komanso kukwera kwapakati.
