Ingabe uketshezi lwangaphambi kokuchama (precum) lungaba mhlophe, futhi lokho kuchaza ukuthini?
Kunoma ubani oke wazibuza ukuthi ingabe i-precum ingaba mhlophe, impendulo inemigudu eminingi, kanti ukuqonda ukuthi kungani uketshezi lwangaphambi kokuchitheka kwesidoda lubukeka ngendlela olubukeka ngayo kungasusa ukukhathazeka okungadingekile. Uketshezi lwangaphambi kokuchitheka kwesidoda, oluvame ukubizwa nge-precum, pre‑sperm, noma uketshezi lwezindlala zika-Cowper, luwuketshezi olucacile noma olufiphele kancane olukhipha indoda esithweni sayo sangasese ngesikhathi sokuvuswa ngokocansi ngaphambi kokuchitheka okuphelele kwesidoda. Lukhiqizwa ikakhulukazi izindlala ezibizwa nge-bulbourethral glands ezimayini ezimbili, kanti ngamazinga amancane lukhishwa nezindlala zika-Littre; lolu ketshezi lunezinjongo eziningi: luyazinciphisa i-asidi esele ku-urethra, lunikeze amafutho okugcoba ukuze ukungena kube lula, futhi lungase luthwale inani elincane lesidoda esisele kokuchitheka kwangaphambilini. Njengoba luvela ngaphambi kwe-orgasm, abantu abaningi bayabuza umbala we-precum noma umbala we-pre‑cum, ikakhulukazi uma bebona ukushintsha okuncane kombala besuka ngomunye umzuzu beya komunye [1].
IBhayokhemistri Engemuva Kwebanga Lombala
Ukwakheka okuyisisekelo koketshezi lwangaphambi kokuchitheka kwesidoda amanzi, ama-electrolytes, ushukela olula njengogalactose ne-glucose, kanye nama-mucoproteins anika lolu ketshezi ubuso obushelelayo. Lezi zithako ngokwemvelo zicacile, yingakho umbala ojwayelekile we-precum uchazwa njengocwebile njengengilazi. Nokho, ukwehluka okuncane kwenani lamaprotheni, i-pH, kanye nokuba khona kwamangqamuzana esikhumba sangaphakathi esesuke (exfoliated epithelial cells) kunganika lolu ketshezi ukubukeka okungathi buyakhipha ubisi okuncane abanye abakuchaza njengokumhlophe okuncane. Ngakho-ke, ukubuza ukuthi ingabe i-precum imhlophe noma ukuthi yini umbala we-precum kuyamukeleka, ngoba ngaphansi kokukhanya kwegumbi lokugezela uketshezi lungabukeka lukhanyayo kunokuthi lucace ngokuphelele [2].
Izinto Ezingenza Uketshezi Lwangaphambi Kokuchitheka Lubonakale Lumsulwa Mhlophe
Umbala omhlophe okhanyayo uvamise ukubonisa ukugxila kwamaprotheni okungalimazi noma amaseli ambalwa esidoda angasebenzi axubana nalokhu kuvuza. Ukuchitheka kwesidoda okusanda kwenzeka kuyimbangela evamile yalokhu kuhlanganeka; isidoda esisele ku-urethral bulb singase sitshikilizwe phambili walandelwa igagasi elilandelayo loketshezi lwezindlala zika-Cowper. Ukungaphuzi amanzi ngokwanele kunciphisa uketshezi emzimbeni, kugxilise izixazululo futhi kugcizelele ukufipheleka. Ngaphezu kwalokho, indlela obheka ngayo, umbala wendawo lapho kuwela khona uketshezi, ngisho nokukhanya kwekhamera yeselula kungathinta indlela ozwa ngayo umbala we-precum. Ngamanye amazwi, umbala woketshezi lwangaphambi kokuchitheka ekuseni lapho kukhanya kakhulu ungahluka ekubukekeni kwawo ebusuku lapho kukhanya kancane.
Nini Lapho Umbala Omhlophe Uba Isixwayiso
Nakuba ukufipheleka okumhlophe kuvame ukuba yinto engeyona inkinga, ukuguquka kube ukuvuza okuphindayo, okushuneka, noma okunephunga elibi kudinga ukuhlolwa kwezokwelapha. Izimo ezifana ne-urethritis, prostatitis, noma izifo ezithathelwana ngocansi zingashintsha ukucaca okuvamile. Uketshezi olune-pus olunombala ophuzi noma oluhlaza, okuxutshaniswe negazi, noma oluhambisana nomuzwa wokushisa lapho uchama kudinga ukuhlolwa ngesikhathi esifanele kwelebhu kanye nokuhlolwa komchamo. Khumbula ukuthi ukuzizwela nokuzelapha ngokususelwa kuphela kumbala we-precum akuthembekile; ukuhlolwa kochwepheshe kuyindlela ehlonishwa kakhulu uma kuvela izimpawu [3].
Ukuqhathanisa Uketshezi Lwangaphambi Kokuchitheka Nesidoda
Ngenxa yokuthi isidoda sivamise ukuba mhlophe futhi singabonakali ngaphakathi, abantu abaningi bayazixubanisa lezi zitho ezimbili futhi babuze ukuthi umbala we-pre‑sperm uyini. Umehluko oyinhloko ukuthi isidoda siqukethe inani elikhulu lamaseli esidoda (spermatozoa) amisiwe ezimfihlakalweni zezindlala ze-seminal vesicle ezicebile nge-fructose ne-prostaglandins, lokho okunika ukuchitheka kwesidoda ukubukeka okukhulu, okumhlophe futhi okujiye. Ngokuphambene, uketshezi olumsulwa lwezindlala zika-Cowper luhlala luwuketshezi olunamanzi futhi olucacile kakhulu. Noma kunjalo, umngcele phakathi kwazo awuhlali ucacile; inani elincane lesidoda lingavuza ngaphambi kwe-orgasm, likhexe umbala onjengekhrimu okwenza abantu babuze umbuzo othi umbala we-pre nut uyini phakathi kwabalingani abanentshisekelo.
Izinkolelo Zamasiko Neziphosiso
Izithombe ezidumile emsakazweni nasemculweni zivame ukukhombisa uketshezi lwangaphambi kokuchitheka njengokungabonakali noma lufane nesidoda, okukhulisa ukudideka mayelana nombala wangempela woketshezi lwangaphambi kokuchitheka ekuphileni kwansuku zonke. Amanye ama-foramu aku-inthanethi athi uketshezi olufiphele luwubufakazi bokuzala okuphezulu, kanti amanye agcizelela ukuthi ukuvuza okucacile ngokuphelele kusho ukuthi awekho amaseli esidoda. Kodwa-ke, izifundo zesayensi zibonisa ukuthi inani lesidoda ku-precum liyahluka kakhulu futhi lixhumene kakhulu nesikhathi esedlule selokhu kwagcina kwachitheka isidoda kunokucaca kwalo ngokubonakalayo. Ngakho-ke, izinqumo mayelana nokuvikela ukukhulelwa akufanele zisekelwe emibaleni ebonakalayo kuphela.
Indima Yokudla, Indlela Yokuphila Nempilo
Izindlela zokuphila zingakwazi ukushintsha kancane umbala we-precum. Ukudla okuningi kokudla okucebe nge-carotenoids njengamakherothi namazambane asawolintshi kungafaka umbala ophuzi kancane eketshezini lomzimba, nakuba lokhu kubonakala kakhulu emjulweni nasemafutheni esikhumba kunaketshezi lwezindlala zika-Cowper. Ukubhema kanye nokuphuza utshwala isikhathi eside kungajiyisa konke uketshezi lwamafinyila emzimbeni, okungenza uketshezi lwangaphambi kokuchitheka lubonakale lufiphele. Ukuphuza amanzi kahle, ukudla okunempilo, nokuzivocavoca njalo kusiza ukusebenza kahle kwezindlala, kuqinisekisa ukuthi umbala we-pre‑cum uhlale ngaphakathi kwebanga elijwayelekile kusukela kokucacile kuya kokumhlophe kancane [4].
Ukuhlolwa Kwelabhorethri Koketshezi Lwangaphambi Kokuchitheka
Odokotela abaningi abahloli uketshezi lwangaphambi kokuchitheka emsebenzini wansuku zonke, kodwa izikhungo ezikhethekile zokuzala kwezingane kwesinye isikhathi ziqoqa amasampula ukuze akale i-pH, inani le-fructose, nokuba khona kwama-leukocytes. Uma kubukwa ngaphansi kwe-microscope, uketshezi olujwayelekile lwezindlala zika-Cowper luvame ukuba necala elincane lamangqamuzana, kube khona kuphela amaseli esikhumba sangaphakathi asuke kancane, futhi, kuya ngesikhathi, inani elincane lamaseli esidoda ahambayo noma anganyakazi. Uma amaseli okubola (amaseli okuzivikela) ebusa esibonelweni, isampula ibhekwa njengokungenzeka ukuthi inenfeksi. Lolu hlolo lunikeza izimpendulo eziqondile mayelana nombala we-precum futhi luchaza ukuthi ukubukeka okumhlophe noma okufiphele kuyinkomba yokugula noma cha.
Imiphumela Esisebenzayo Ekuzivikeleni Ekukhulelweni Nasekukhiqizeni
Amathuba okuba kube nesidoda ku-uketshezi lwangaphambi kokuchitheka asho ukuthi indlela yokuhoxa ngaphambi kokuchitheka kwesidoda inengozi ethile yokukhulelwa. Nakuba iphesenti lamasampula ane-sidoda lihlukahluka ezifundweni, ucwaningo luveza njalo ukuthi okungenani abanye besilisa banamaseli esidoda asebenzayo ku-precum yabo. Ngakho-ke, umbala wedwa awukwazi ukuqinisekisa ukungabi namandla okuzala; noma uketshezi lubukeka lucacile noma lufana nobisi, ukusebenzisa izindlela ezivimba (isb. ikhofu) kusalokhu kunconywa kulabo abafuna ukugwema ukukhulelwa. Ngokuphambene, abashadile abafuna ukukhulelwa kwesinye isikhathi bacabanga ukuthi ukuvuza okumhlophe kakhulu kubonisa inani elikhulu lesidoda, kodwa alukho ubudlelwano obuqinile phakathi kombala obonakalayo nenani lesidoda.
Umthelela Wengqondo Nokuxhumana
Ukukhathazeka mayelana nokuvuza okuphuma esithweni sangasese kuvamile, kanti ukungaqiniseki mayelana nombala we-pre‑sperm kungandisa imizwa yokujabhala ngesikhathi sobulili. Ukuxoxa ngokusobala nabalingani mayelana noketshezi olujwayelekile lomzimba kunganciphisa ihlazo futhi kukhuthaze okuhlangenwe nakho kocansi okunempilo. Othisha bezempilo bagcizelela ukusebenzisa amagama anembile emzimbeni kanye nolwazi olususelwe ocwaningweni, bafake esikhundleni izilimi zemihlangano ezifana ne-pre nut ngezincazelo ezicacile mayelana nokusebenza kwezindlala. Ukwazi ukuthi ukwehluka kombala we-precum kuvame ukuba yinto engalethi ingozi kusiza abantu bagxile ekuthokoziseni kunokukhathazeka [5].
Ukubhekana Nemibuzo Evame Ukubuzwa
Abantu bavame ukubuza ukuthi umbala we-precum kufanele ube yini. Imibiko eminingi iveza ukuthi uketshezi olujwayelekile lwezindlala zika-Cowper luphakathi kokucacile ngokuphelele nokufiphele kancane. Olunye umbuzo ovamile, ukuthi ingabe i-precum imhlophe njalo yini, udinga impendulo ecacile: ingaba mhlophe, kodwa ngokufanayo ingaba ngaphandle kombala kuye ngezinto ezixoxwe ngenhla. Abanye bayabuza, umbala woketshezi lwangaphambi kokuchitheka uba yini lapho indoda ivuswa kakhulu? Ukugeleza kwegazi okwandayo kanye nokusebenza ngokweqile kwezindlala kungase kwandise ivolumu yoketshezi, okwenzela ukuthi ukukhanya kusakazeke nokuvuse umbala ophaphathekile, kodwa ukwakheka kwebhayokhemikhali kwalo kuhlala kungashintshi.
Ukuguquguquka Kwamahomoni Empilweni Yonke
Imijikelezo yamahomoni isebenza ekwakheni inani nokubukeka kwazo zonke izikhipho zesitho sangasese, kanti uketshezi lwangaphambi kokuchitheka akuwona umphumela ohlukile. I-testosterone ilungisa izindlala ze-bulbourethral, kodwa amahomoni afana ne-prolactin, cortisol kanye nehomoni zesitho se-thyroid ashintsha ukujiya nombala. Ezikhathini zokucindezeleka okukhulu, amazinga aphezulu e-cortisol anganciphisa okwesikhashana ukukhiqizwa kwezindlala, okwenza ivolumu encane ephumayo ibonakale ijiyile futhi ngenxa yalokho ibukeke imhlophe kakhulu. Ngokuphambene, amadoda athola ukwelashwa nge-testosterone replacement avame ukubona ukwanda kokugeleza okuhambisana nokucaca okukhulu njengoba amaprotheni eba bancane phakathi komthamo omkhulu woketshezi.
Umthelela Wemithi Ejwayelekile
Imithi eminingi ingashintsha nokuthi uketshezi lwangaphambi kokuchitheka lubukeka kanjani. Ama-antihistamine, isibonelo, awomisa izindlala ezikhiqiza uketshezi emzimbeni wonke, kwesinye isikhathi kuholele ekuvuzeni okuncane, okujiye okubonwa abasebenzisi njengokumhlophe okungajwayelekile. Imithi ye-selective serotonin reuptake inhibitors, esetshenziselwa ukwelapha ukudangala nokukhathazeka, kubikwe ukuthi yehlisa uketshezi lwesondo; lapho kukhiqizwa uketshezi oluncane, izinhlayiya ezincane ziyabonakala kakhulu, zikhiphe umbono wokuthi lufana nobisi. Ngakolunye uhlangothi, ama-alpha‑blockers asetshenziswa ekwandeni kwe-prostate angandisa ivolumu yoketshezi, okwenza uketshezi lubonakale lucacile kakhulu futhi lokho kududuze iziguli ebezikhathazekile ngokufipheleka kwalo phambilini.
Umehluko Obangelwa Iminyaka Nempilo Yesikhathi Eside
Njengoba amadoda eya eminyakeni, kuba nezinguquko zesakhiwo sezicubu (histological changes) ngaphakathi kwezindlala ze-bulbourethral, okuhlobene nenani nembangela yoketshezi lazo. Abantu abadala abaseminyakeni yokuqala yobudala bavame ukukhiqiza inqwaba yoketshezi olucacile ngoba imisele yezindlala ivulekile futhi ayivinjiwe. Ngemva kweminyaka ephakathi nendawo, ukwakheka kwezicubu eziqinile (fibrosis) kunganciphisa lezi ziteshi, kunciphise ukugeleza futhi kuvumele amaprotheni ukuthi agxile, okwehlisa umbala ube mhlophe kwesinye isikhathi. Ukuzivocavoca ngokomzimba njalo okungokwe-aerobic nokuphuza amanzi ngokwanele kusiza ukugcina imisele ithambile, okubonisa ukuthi indlela yokuphila inganciphisa imiphumela yokuguga. Nokho, noma yiluphi ushintsho olusheshayo lombala ludinga ukuhlolwa, kungakhathaliseki iminyaka [6].
Ukuqaphela Nini Ukubonana Nochwepheshe Bezempilo
Noma yikuphi ukushintsha okuqhubekayo kube ukuvuza okukhulu, okuphuzi, okuluhlaza, noma okuxutshaniswe negazi, ikakhulukazi uma kuhambisana nokushisa, ukuluma, noma ubuhlungu besifuba sangaphansi, kufanele kudale ukuthi ubone udokotela. Izivivinyo ezisheshayo zokuhlola izifo ezithathelwana ngocansi nezifo zomchamo zilula futhi zingashesha ukugudluza izimbangela ezimbi. Ukwelashwa kusenesikhathi akusizi nje kuphela ukuphelisa izimpawu kodwa futhi kuvimbela imiphumela emibi njengokulimala kwe-urethra noma izinkinga zokuzala.
Umqondo Oyinhloko
Ukwehluka kokubukeka koketshezi lwangaphambi kokuchitheka kuyinto evamile, futhi ukuveza umbuzo othi umbala we-pre‑cum uyini noma ingabe i-precum ingaba mhlophe kubonisa isifiso esinempilo sokwazi ngempilo yezocansi. Ngaphansi kwezimo ezijwayelekile, i-pre‑cum icacile; kodwa ukufipheleka okuncane okubangelwa amaprotheni, isidoda esisele, noma izimo zokukhanya kusaphakathi kwebanga elijwayelekile. Umbala wedwa awuyona inkomba ethembekile yenfeksi, amandla okuzala, noma isimo samahomoni. Ukuphuza amanzi kahle, ukwenza ucansi oluphephile, nokufuna iseluleko sezokwelapha uma kuba nezinguquko ezinkulu yizona zindlela ezingcono zokuthola ukuthula kwengqondo.
