Izitho Zokwabelana Ngocansi: I-Anatomy Yokuzala Kwabesilisa Nabesifazane

Izitho zokwabelana ngesocansi yizo zitho ezinomthwalo wemfanelo wokwenza umsebenzi wocansi noma wokuzala. Isitho sokwabelana ngesocansi emadodeni yi-penis enendima enkulu ngesikhathi sokwabelana ngesocansi [1].

Kwabesifazane, isitho esiyinhloko sokwabelana ngesocansi yi-vagina. Inendima enkulu ngesikhathi sokwabelana ngesocansi futhi iphinde ibe yindlela lapho usana ludlula khona ekubeletheni kanye nendlela yokuphuma kwegazi lenyanga [2]. Ukufunda ngezitho zokwabelana ngesocansi noma izitho zangasese ohlelweni lokuzala lwesilisa nowesifazane kubalulekile ukuze kuqondwe ukusebenza kwazo kahle nokuthola noma yiziphi izinkinga kusenesikhathi.

Kule ndatshana, sizofunda ngezitho zangasese zabesilisa nabesifazane futhi sibone ukuthi zisebenza kanjani ekuzaleni.

I-penis: Isitho Sangasese Sowesilisa Sokwabelana Ngesocansi

Isakhiwo sezitho zokuzala zesilisa nowesifazane sidlala indima esemqoka ekuzaleni kwabantu, sihlanganisa izakhiwo eziklanyelwe ukuchumisa, ukukhulelwa nokuzalwa. I-penis iyisitho sangasese sowesilisa sokwabelana ngesocansi esinokwakheka okukhethekile kokuzala. Yona iyona sitho esikhulu ohlelweni lokuzala elinomthwalo wemfanelo wokukhulula isidoda sowesilisa ngesikhathi sokuchama okuhlotshaniswa nocansi (i-ejaculation). I-penis iphinde isebenze njengendlela yokuphuma komchamo. Ekuzuzeni ukuqonda ukuthi imuphi umsebenzi wokuzala walezi zitho, kubalulekile ukuqonda ukuthi ukuzala kudinga ukubambisana phakathi kohlelo lwesilisa nohlelo lowesifazane.

I-penis inezingxenye ezintathu ezinkulu: impande, umthungo, ne-glans [3]. Impande yisisekelo, ebopha i-penis emzimbeni. Umthungo uyindawo ende, eyindilinga, kanti i-glans yithiphu ebucayi, eyindilinga.

Umthungo uyisakhiwo esivelele kunazo zonke kunoma iyiphi idiagramu yokwabelana ngesocansi. Lezi zakhiwo zisebenzisana ngesikhathi somsebenzi wocansi nasekuzaleni.

I-penis iqina ibe mpo lapho umuntu ezwa uthokozo locansi, okudingekayo ukuze ibe nomsebenzi ekuzaleni. Iqina uma igazi lingena ku-penis, ligcwalisa izicubu ezithambile ezifana nesipontshi ngaphakathi komthungo wayo. Imisipha iyaphumula, ivumele leli gazi ukuthi lihlale lingaphakathi, okwenza i-penis iqine futhi ime mpo. Ucwaningo olubheka uhlangothi lwesilisa nowesifazane emzimbeni lubonisa ukuthi lawo masistimu womabili azuzelana kanjani ukuze kwenzeke ukuzala.

I-vagina: Isitho Sangasese Sowesifazane Sokwabelana Ngesocansi

I-vagina iyisitho sangasese sowesifazane sokwabelana ngesocansi, okuyi-kanali enemisipha esesendaweni ephakathi kwesibeletho nezitho zangasese zangaphandle. I-vagina inomsebenzi obalulekile ekwabelaneni ngesocansi, ekubeletheni nasekuchithweni kwegazi lenyanga. 

Kokubili ipipi nomgodla wesitho sangasese sowesifazane kuhlukaniswa ngaphansi kwe-anatomy yezakhiwo zezinso zangasese ezibalulekile ekukhulelweni kwemvelo.

Isitho sangasese sowesifazane, ngokwesilinganiso, siwu-3 kuya ku-4 intshi ubude, futhi sizungezwe izindwangu ezikhipha umucu (mucous membranes). Njengoba siyithumbu eliguquguqukayo, siyavuleka ukuze samukele ipipi ngesikhathi socansi.

Liyakhululeka futhi likhule ngesikhathi sokubeletha, likuvumele ingane ukuba iphume emzimbeni kukanina. Ngesikhathi sokuya esikhathini, isitho sangasese sowesifazane (umgodla) siphinde sisebenze njengendlela yokuphuma kwegazi neminye imfucuza ephuma esibelethweni.

Owesilisa No wesifazane Umdwebo Wohlelo Lokuzalana

Umdwebo wezitho zokuzalana zewesilisa nowesifazane unikeza isethulo esicacile sokubukeka kwezitho ezibandakanyekayo ekuzaleni. Imidwebo yohlelo lokuzalana komuntu inganikeza ulwazi olubalulekile mayelana nokwakheka nokusebenza kwezingxenye ezahlukene zomzimba wesilisa nowesifazane. Imidwebo yezitho zokuzalana zewesilisa nowesifazane iphinde yenze kube lula ukuqonda izimbangela zezinkinga zokuzala.

Imibhalo yezokwelapha ivame ukubhekisela kumdwebo wohlelo lokuzalana lwesilisa nowesifazane ukuze ichaze i-anatomy yezitho zocansi nemisebenzi yokuzalana ezindaweni zemfundo nezokwelashwa. Ngezansi kunomdwebo wohlelo lokuzalana wesilisa nowesifazane obonisa izingxenye ezisemqoka ezibamba iqhaza ekuzaleni komuntu.

I-Anatomy Yohlelo Lokuzalana Lwabesilisa

Uma uzama ukuqonda ukuthi ukuzalana komuntu kusebenza kanjani, ukubuka umdwebo wokuzalana onamabhuloho (labeled) kungaba usizo olukhulu lokubona ngeso lengqondo.

Nansi umdwebo wohlelo lokuzalana kowesifazane:

I-Anatomy Yohlelo Lokuzalana Lwabesifazane

Lemidwebo inikeza umbono olula wezingxenye zomzimba womuntu wesilisa nowesifazane ezibalulekile ekuqondeni impilo yokuzalana nokukhula.

I-Anatomy Yohlelo Lokuzalana Lwabesilisa

Uhlelo lokuzalana kowesilisa lubhekene nokukhiqiza nokuhambisa isidoda ukuze kube nokuzalana. Luqukethe izitho zangasese zangaphandle nezangaphakathi ezisebenzisana ukuqinisekisa ukusebenza kahle [4]. Izitho ezinkulu kuhlelo lokuzalana kowesilisa zifaka amasende, i-vas deferens, i-epididymis, kanye nesinye se-prostate, ngasinye sinendima yaso ehlukile ekukhiqizeni inzalo.

Izitho Zangaphandle Zowesilisa

Izitho zangaphandle zibhekisela kulezo zitho zocansi ezisemphakathini ngaphandle komzimba. Lokhu kuhlanganisa:

• Ipipi: Ipipi yilo eliyinhloko lesitho sokuzalana ku-anatomy yezitho zangasese ziwesilisa. Lisebenza njengomsele wesidoda sowesilisa ngesikhathi sokufafaza isidoda (ejaculation) kanye nomchamo ngesikhathi sokuchama.

Isakhiwo somthondo sifaka umzimba womthondo kanye nenhloko (ithiphu), nezicubu ezivuvukalayo ezimvumela ukuthi ube lukhuni uma evuswa ngokocansi, okwenza ukuya ocansini kwenzeke [3].

• Isikhwama Samasende: Isikhwama samasende yisikhwama sesikhumba esibamba amasende ngaphandle komzimba. Lesi sikhundla sisiza ukulawula izinga lokushisa lamasende, liwagcine epholile kancane kunomzimba wonke, okubalulekile ekukhiqizweni okuphilayo kwesidoda [5].

Izitho Zangaphakathi Zesilisa

Izitho zangaphakathi ohlelweni lokuzala lwesilisa zifaka:

• Amasende: Amasende yizitho zokuzala zesilisa (gonads) ezinesibopho sokukhiqiza isidoda ne-hormone i-testosterone. I-testosterone inesibopho sokuthuthuka kobulili kubesilisa [6]. Amasende anesibopho sokukhiqiza izigidi zamangqamuzana esidoda nsuku zonke.
• I-Epididymis: I-epididymis iwushubhu otholakala ngemuva kwelungu ngalinye lamasende onomumo wokusongoza. Lapha kugcinwa khona isidoda futhi sivuthwe ngemuva kokukhiqizwa emasendeni. Isidoda siphinde sithole ikhono lokubhukuda kulesi sigaba.

• Vas Deferens:\u00a0I-vas deferens yaziwa nangokuthi ipayipi elithwala isidoda. Iwushubhu omude othwala isidoda esivuthiwe sisuka ku-epididymis siye ku-urethra. Lapha, uketshezi lwenzalo olunempilo nesidoda kuyaxubana ukuze kwakheke isidoda esiwuketshezi ngaphambi kokuchama okunezidoda.

• I-Prostate Gland Nama-Seminal Vesicles: Uhlelo lokuzala lwesilisa lunezindlala ezincane ezikhiqizayo ezahlukene, okuhlanganisa i-prostate gland nama-seminal vesicles. Lezi zindlala zinikela ekukhiqizweni kwesidoda esiwuketshezi ngokwengeza uketshezi olondla isidoda. Lezi zindlala zibhekwa njengezitho ezinkulu ohlelweni lokuzala ngenxa yendima yazo ekwenzeni ukuchumisa kuphumelele. Ziphinde zivikele isidoda ngesikhathi sohambo laso ngaphakathi kohlelo lokuzala lowesifazane.

Isakhiwo Sohlelo Lokuzala Lowesifazane

Uhlelo lokuzala lowesifazane luwakheka okuyinkimbinkimbi oluhloselwe ukusekela ukukhiqizwa kwamaqanda, ukuchumisa, nokukhulelwa [7]. Izitho ezinkulu zohlelo lokuzala kwabesifazane zifaka ama-ovari, isibeletho, amashubhu e-fallopian, nesitho sangasese sowesifazane. Iqukethe kokubili izitho zangaphandle nezangaphakathi, ngayinye idlala indima ebalulekile ekuzaleni.

Izitho Zangaphandle Zowesifazane

Izitho ezivezwa emvelweni yangaphandle zifakwa ezithweni zangaphandle, futhi lezi zifaka:

• I-vulva: I-vulva ifaka izingxenye zangaphandle zezilungu zangasese zabesifazane, ivikele izitho zokuzala zangaphakathi. Iquka i-labia majora, i-labia minora, kanye nomlomo wangaphandle we-vagina [8]. Umsebenzi walo oyinhloko ukusebenza njengesithiyo nokusiza ekuvukeni kwezocansi.
• I-clitoris: I-clitoris iyitho elincane kodwa elizwela kakhulu elibhekele ukuvuka kwezocansi. Liqukethe imithambo eminingi yezinzwa futhi, lapho lishukunyiswa, lingandisa injabulo yezocansi.

Izitho Zangaphakathi Zabafazi

Izitho ezingaphakathi kohlelo lokuzala lwabesifazane yilezi:

• I-vagina: I-vagina iyindlela enemisipha exhunga izitho zangasese zangaphandle nesibeletho. Isidoda sidlula kule ndlela ngesikhathi socansi. Ekugcineni, isebenza njengomgudu wokubeletha ngesikhathi sokuzalwa komntwana.
• Isibeletho: Isibeletho, esaziwa kabanzi ngokuthi isizalo (womb), siyithambo elingenalutho elinemisipha lapho iqanda lizimbe khona ngemva kokuchumelana bese lithuthuka libe yisisu somntwana. Linikeza ukudla nokwesekwa embungwini okhula ngesikhathi sokukhulelwa.
• Ama-ovari: Ama-ovari akhiqiza amaseli okuzala abesifazane abizwa ngamaqanda (ova). Enye imisebenzi ebalulekile yama-ovari ukukhulula amahomoni afana ne-estrogen ne-progesterone. Lawa mahomoni alawula umjikelezo wokuya esikhathini futhi asekele ukukhulelwa.
• Amashubhu e-fallopian: Amashubhu e-fallopian ayixhumo phakathi kwama-ovari nesibeletho. Kuyindawo lapho ukuchumelana kwenzeka khona. Uma iqanda selichumile, lehla liye esibelethweni ukuze lizimbe khona.

Ukuqonda kabanzi isakhiwo sezitho zangasese kusiza ukubona ukuthi izitho zabesifazane zizivumelanisa kanjani nezinqubo ezifana nokuya esikhathini, ukuchumelana nokubeletha.

Izinkinga Ezivamile Zokuzala Kwabesilisa

Isakhiwo somzimba wendoda nesistimu yokuzala yabesifazane kuhluke kakhulu komunye nomunye, yingakho bobabili benezinkinga zokuzala ezikhethekile.

Amadoda angahlangabezana nezinselelo ezihlukahlukene zempilo yokuzala ezithinta izitho zawo zangasese nezinga lokukwazi ukuzala. Lezi zifaka phakathi:

• Ukungasebenzi kahle kwamandla ocansi (Erectile Dysfunction): Kuyisimo lapho indoda ingakwazi ukuthola noma ukugcina ukuvuthwa kobudoda isikhathi eside ngokwanele ukuze kwenzeke ucansi.
• I-Prostatitis: Ukuvuvukala kwesigcunsula (prostate gland) kungathinta ukusebenza kwezocansi kanye nokwakheka okuphelele kwezitho zangasese.
• Amazinga e-testosterone aphansiI-testosterone encishisiwe ingathinta i-libido, ukukhiqizwa kwesidoda, nokuthuthuka kwezingxenye zomzimba ezocansi.

Lezi zimo zingathinta izingxenye zomzimba zabesilisa nabesifazane ezibandakanyekayo ekuzaleni futhi zehlise amathuba okukhulelwa ngokwemvelo.

Izinkinga ezivamile zokuzala kowesifazane

Abesifazane baphinde bahlangabezane nezinselelo zempilo yokuzala ezingathinta ukuzala kowesifazane. Lezi zifaka phakathi:

• Isifo sama-ovary ane-polycystic (PCOS): Ukungalingani kwamahomoni kuyimbangela enkulu ye-PCOS. Lesi simo singaholela emjikelezweni wokuya esikhathini ongajwayelekile, okwenza kube nzima kwabesifazane ukukhulelwa.
• I-endometriosis: I-endometriosis yisimo lapho izicubu ezifana nendwangu yangaphakathi yesizalo zikhula ngaphandle kwesizalo. Kubangela ubuhlungu, ukungakhululeki, nezinkinga zokuzala.
• Ama-fibroid: Ama-fibroid ayizimila ezingeyona umdlavuza esizalweni ezingathinta impilo yokuzala nokukhulelwa. Ngokutadisha izitho zohlelo lokuzala nokubuka imidwebo enembile, abantu bangakwazi ukuqonda kangcono impilo yabo yokuzala futhi babone izinkinga ezingaba khona zisasekuqaleni.

Okubalulekile ekugcineni

Ipipi yisitho socansi sowesilisa, kanti isitho sangasese sowesifazane (i-vagina) yisitho socansi sowesifazane. Lezi zitho zibamba iqhaza enqubweni yokwazana ocansini futhi zenza neminye imisebenzi emzimbeni. Igama elithi isitho socansi libhekisa esakhiweni sokuzala esibandakanyekayo ocansini futhi sibalulekile ekukhulelweni ngokwemvelo.

Ipipi livumela umchamo ukuthi udlule kulo ngaphezu kokukhishwa kwesidoda. Ngokufanayo, isitho sangasese sowesifazane (i-vagina), ngaphezu kokubamba iqhaza ocansini, sisebenza njengendlela yokuphuma komntwana ngesikhathi sokubeletha nokudlula kwegazi lokuya esikhathini ngesikhathi sokuya esikhathini.

Ukugcina impilo yezitho zomzimba zobulili noma izingxenye zomzimba zabesilisa nabesifazane kubalulekile ekuzaleni nasekukhuliseni amathuba okukhulelwa.
