Isithintelo Sithinteka Njani?
Inkqubo yokuzala izalathisi iquka iimvavanyo, iiderm, i-prostate gland, urethra kunye ne-penis. Ngelishwa, njengamanye amathishu amaninzi omzimba womntu, i-cancer iyakhula ukusuka kwinkqubo yokuzala. Umhlaza wesifo seprotate ngowona mdlavuza oqhelekileyo wendlela yokuzala inzala elandelwa yimihlaza yesifo somzimba, equkethe iintlobo ezahlukeneyo.
Umhlaza wesantya uvela kumathambo, awaziwa ngokuba yi-testes, ubuninzi be-testis.
Sibanzi
Igama elipheleleyo lentsholongwane yesilwane ngu-spermatozoon, ubuninzi be-spermatozoa. Inambuzane yesinqa iyahluke kuzo zonke ezinye iiseli zomzimba womntu ngokuba yilo kuphela uhlobo lweseli oluqukethe isethi enye yama-chromosomes, kanti zonke ezinye iiseli ziqukethe iiseti ezimbini zechromosome nganye. Idibanisa neqanda, enekhophi enye yama-chromosomes omama, okubangela isethi epheleleyo yama-chromosomes. Le setethi yama-chromosomes i-akhawunti yabaninzi beempawu zomntu oza kuzalwa.
I-Sperm idlula kwizigaba ezintathu eziphambili: ukuveliswa, ukugcinwa, nokuhanjiswa.
U ku velisa
Inkqubo yokudalwa kwesilisa kuthiwa yi-spermatogenesis. Iyenzeka kwingingqi yeemvavanyo ezibizwa ngokuba yi-tubini ze-seminiferous. Kwii-tubini ze-seminiferous zifunyenwe iiseli ze-spermatogonia ezivela kuyo iiseli zesininzi.
Njengoko ibhinqa ihamba ngee-tubini ze-seminiferous, zondliwa kwaye ziyaqhubeka zikhula. Kwiintsuku ezingama-200-400 izigidi ziveliswa ngalunye usuku.
Ukugcina
Isidakamizo siphumela kwiimithi ze-seminiferous kwaye zifake i-epididymis, enye enye isakhiwo esibucayi. I-Sperm iyaqhubeka nokuphuhliswa kweli nqanaba kwaye ekugqibeleni igcinwe ekupheleni kwe-epididymis.
Ngokuqhelekileyo kuthatha malunga neenyanga ezi-3 ukuze isidoda siphumelele ngokupheleleyo.
U kuziswa
Ngokuvuselela ngokwaneleyo kwinkqubo yesantya, i-contraceptions ye-muscle ehamba phambili iqhuba i-sperm kwi-epididymis ibe yi-vas deferens (eyaziwa nangokuthi i-ductus deferens) ejikeleza i-bladder kwaye idlulela kwisitya esicacileyo, esise-prostate gland. Le nkqubo iyaziwa njengento yokukhwabanisa kwaye iyenzeka ngokukhawuleza ngaphambi kokunyuka. Ngaphambi nje kokuba i-conjection ejaculatory, i-vesicle ye-semicle inikezela umthamo ocebileyo wezondlo owenza ubuninzi bomthamo we-ejaculate. I-prostate igalela kwakhona umbane osebenzayo ukunciphisa i-pH nokukhusela isityalo. Ukususela apho isidoda, esaziwa ngokuba yi-semen kuba isuka kwi-vesicle vesicles, isusiwe phantsi kwe-urre and out penis. I-sphincter muscle ejikeleze i-urethra kwiintlondi zeprotate ukukhusela umdaka ukuba ungangeni kwisikhokelo esingafanelekanga kwisitya.
Imiphumo enokwenzeka
Ngaphambi kokuba unyango lweNtsholongwane
Ezinye izifundo zicebise ukuba amadoda anomdlavuza womhlaza anesibonakaliso sokukhubazeka kwe-spermatogenesis nangaphambi kokuba unyango. Isizathu esicacileyo salokhu asikacacanga, kodwa sinokuthi sihambelane neziganeko ezibangelwa ngumhlaza wesifo somdla wokuqala kwindawo efana ne- cryptochidism .
Ukulandela i-Chemotherapy okanye i-Radiation
Zombili i- chemotherapy kunye neyeza zonyango zingaphazamisa i-spermatogenesis. Ephakamileyo umthamo we-chemotherapy, omkhulu umngcipheko wokungapheli.
Ukulandela uRLND
I-retroperitoneal lodeph node dissection yindlela yokutshatyalaliswa kwe-lymph nodes kwisisu esisenza i-lymph iqulethwe kwi-testes. Le yindawo yokuqala yokusasaza i-cancer ye-testicular kunye nokuhlinzwa kunokubaluleka ekunyangeni umhlaza. Iimbongo ezijongene nenkqubo yokudibanisa yokudlulela ejaculation ukudlula kwintambo yomgogodla kule ndawo. Ezi zinzwa zingathinteka ngophengululo olubangelwa imeko eyaziwa ngokuba yi-retrograde ejaculation.
Njengoko kukhankanywe ngasentla, ngexesha lokunyuka, i-contracts muscle ye-sphincter ngaphambi nje kwesikhumba, ukuthintela umlenze ukuba ungene kwicala elingalunganga (retrograde) kwi-bladder endaweni ye-urethra nge-penis. Kwi-retrograde ejaculation, i-nerve ejongene nokuqhekeka kwe-sphincter ayisebenzi kakuhle ngoko isisu singena kwisibindi esiphumela kwizinto eziqhelekileyo ezibizwa ngokuba yi-orgasm eyomileyo.
Naliphi na unyango lomhlaza wesondlo lunokubangela ukuba kungabikho kwintsholongwane. I-bermon yaseBermin kufuneka ithathelwe ingqalelo kunoma ubani ofuna abantwana abangabantwana emva kokunyanga.
