Kufotokozera
Kuonjezera apo, kuchepa kwa sedimentation ya umuna kumathandiza kusunga khalidwe ndi kukhulupirika kwa spermatozoa, kuonetsetsa kuti zimagwira ntchito panthawi yosungidwa kwa nthawi yaitali. Popanga, kuphatikiza umuna wokhala ndi matumba ndi ukadaulo woyimitsidwa woyimitsa ungagwiritsidwe ntchito bwino. Kuphatikizikaku kungathe kubweretsa phindu lalikulu, monga kuchepa kwa ndalama zogwirira ntchito komanso kupititsa patsogolo luso la kuswana. Umuna wokhala m'matumba ukhoza kupachikidwa ndikuwongolera mosavuta panthawi yobereketsa, kufewetsa ndondomekoyi ndikuchepetsa nthawi ndi khama lofunika. Kapangidwe kofewa komanso kosalala ka thumba la umuna kumakulitsanso mphamvu yosungiramo umuna.

Kapangidwe kameneka kamachepetsanso kupsinjika kwa umuna, zomwe zimawonjezera mphamvu ndi mphamvu. Kusavuta ndi mwayi wina waukulu wa umuna wokhala ndi matumba.
Thumbalo limatsegulidwa mosavuta ndikuchotsa pakamwa, zomwe zimapangitsa kuti munthu azitha kulowa umuna mwachangu komanso mwachindunji. Kuonjezera apo, chivindikiro chotseguka chingagwiritsidwe ntchito kutseka thumba lotsegula, kupereka chisindikizo chaukhondo ndi chotetezeka. Zothandiza izi zimatsimikizira kuti umuna umasungidwa usanalowedwe komanso utatha. Mapangidwe amtundu wa thumba la umuna amatsimikizira kugwirizana ndi ma diameter onse a vas deferens. Kusinthasintha kumeneku kumapangitsa kuyika kosavuta kwa vas deferens kapena chubu chowonjezera pakulera, kufewetsa ndondomekoyi ndikuchepetsa mwayi wolakwika kapena zovuta.
