Ukukhiqizwa kwesidoda kwenzeka kuphi emzimbeni futhi kusihamba kanjani?

Kwabalingani abazama ukukhulelwa, ukuqonda ukuthi ukukhiqizwa kwesidoda kwenzeka kanjani emzimbeni wesilisa kungaba wusizo kakhulu. Lolu lwazi, kusukela ekudalweni kwesidoda kuze kube wuhambo lwaso lokugcina, lungaba nomthelela omkhulu emizamweni yokuzala. Ngokuhlukanisa le nqubo eyinkimbinkimbi, singakwazi ukubonga kangcono izici ezithinta ukukhulelwa nokuthi singayisekela kanjani impilo yokuzala. Ake sihlole isinyathelo ngasinye sokukhiqizwa kwesidoda, ukuvuthwa kwaso, kanye nendlela elihamba ngayo, singene ngokujulile endleleni yesidoda.

Ukuqala Kokukhiqizwa Kwesidoda

Pho, i-spermatogenesis yenzeka kuphi? Konke kuqala emasendeni, atholakala esikhwameni sesende (scrotum). Amasende yikho lapho ukukhiqizwa kwesidoda kwenzeka khona ohlelweni lokuzala lwesilisa. Ngaphakathi emasendeni kunemigudu emincane, egoqekile ebizwa ngokuthi ama-seminiferous tubules. Lapha yikho lapho emndenini wesilisa i-spermatogenesis yenzeka khona. Lesi sakhiwo yisona sikhungo sokukhiqizwa kwesidoda futhi sibalulekile ekukhiqizeni isidoda [1].

Inqubo Yokwenza Isidoda: I-Spermatogenesis

Ngokwesayensi, yini le nqubo yokukhiqizwa kwesidoda ebizwa ngani? Inqubo okukhiqizwa ngayo isidoda ibizwa ngokuthi i-spermatogenesis, igama elibhekisela ochungechungeni lwezinyathelo eziguqula amangqamuzana okulobolo angakavuthwa abe isidoda esivuthiwe, esikwazi ukuhamba. Inqubo ye-spermatogenesis yenzeka phakathi namasonto amaningi futhi ihilela izigaba ezahlukene [2].

Ngesikhathi salezi zigaba zokuthuthuka kwesidoda, amangqamuzana ayahlukana futhi enze izinguquko, esizwa amahomoni afana ne-testosterone. I-spermatogenesis ikhiqiza izigidigidi zesidoda nsuku zonke, kodwa idinga isikhathi. Ithathela isikhathi esingakanani i-spermatogenesis? Ngokuvamile, ithatha cishe izinsuku ezingu-64 ukuqedwa kusukela ekuqaleni kuze kube sekugcineni [3].

Umyalo Ongcono Kakhulu: Ukugcina ukudla okunothe ngama-nutrient abalulekile afana ne-zinc ne-folic acid kungase kusekele ukukhiqizwa kwesidoda okunempilo.

Isidoda Sivuthaphi?

Ngemva kokwakheka kwaso kokuqala, isidoda asikakulungeli ukwembathisa iqanda. Kumele sivuthwe. Isidoda sivuthaphi? Impendulo ikwi-epididymis, umgudu omude, ogoqekile ophezu kwazo zonke izindlala zesende. Lapha, lapho amangqamuzana esidoda evuthwa khona kubalulekile ngoba lapha yikho lapho isidoda sithola khona ikhono lokuhamba kanye namandla okuchumisa iqanda [4].

Uhambo Lwesidoda: Indlela Yesidoda (Spermatic Pathway)

Lapho esevuthiwe, isidoda siqala uhambo laso ohlelweni lokuzala lwesilisa. Lolu hambo lubizwa ngokuthi indlela yesidoda. Lwaqala ku-epididymis bese ludlula ku-vas deferens, umgudu onemisipha okhipha isidoda siqhubekele phambili. Lokhu kuyingxenye yendlela yesidoda futhi kubalulekile ekususeni isidoda endaweni yokugcinwa liye ekuchamukeni okungenzeka [5].

Umzila wesidoda uyaqhubeka njengoba isidoda sihamba singena emijelweni ye-ejaculatory, lapho sixubana khona noketshezi oluvela kuma-seminal vesicles nasetindlaleni ze-prostate. Lokhu kuxubana kwakha uketshezi lwesidoda (semen), olunikeza ukudla kanye nemvelo efanele ukunyakaza kwesidoda. Umzila wesidoda uqedwa lapho uketshezi lwesidoda lukhishwa (ejaculated) luye ku-urethra luphume emzimbeni.

Uyini umzila wesidoda ngokulandelana kwawo? Uvela emathendeni uye ku-epididymis, bese uya ku-vas deferens, emijelweni ye-ejaculatory, ekugcineni udlule ku-urethra.

Ithiphu Ehloniphekile: Ukuzivocavoca njalo nokugwema ukubhema kungathuthukisa impilo yesidoda futhi kusekele uhambo laso. 

Uma uzibuza ukuthi ukuzivocavoca kukhuphula inani lesidoda yini, qiniseka ukufunda isihloko sethu esichaza ukuthi ukuzivocavoca kungayithinta kanjani inzalo yendoda nokukhiqizwa kwesidoda.

Isidoda Sifinyelela Kanjani Eqandeni?

Isidoda sihamba kanjani? Uma sesichameliwe (ejaculated), isidoda siqala uhambo laso ukuya eqandeni. Umzila wesidoda ubandakanya ukudlula ohlelweni lokuzala lwesifazane, kuqale nge-cervix, siqhubekele esikhala sesibeletho, ekugcineni sifinyelele emapayipini e-fallopian, lapho ukufakelwa (fertilization) kuvamise ukwenzeka khona.

Umzila wesidoda awulona iqonde ngqo. Ugcwele izingqinamba, njengezithiyo zobuso bekherviksi (cervical mucus) nokuncipha kwesibeletho. Yingakho ukuqonda umzila weseli lesidoda kubaluleke kangaka.

Ithiphu Ehloniphekile: Ukuhlala uphuza amanzi anele nokugcina ukudla okunempilo kungathuthukisa ukunyakaza kwesidoda nempilo yokuzala.

Ukugcinwa Nokuvuthwa: Indima Ye-Epididymis

Ngemva kwe-spermatogenesis isidoda sigcinwa ku-epididymis, lapho sihlala khona kuze kube isikhathi sokuchama kwesidoda (ejaculation). Lesi sikhathi sibalulekile ekuvuthweni kwesidoda, sisivumela ukuthi sithole ikhono lokunyakaza nokusebenza elidingekayo ukuze sikhonze ukufaka iqanda. Umzila weseli lesidoda kusukela ekukhiqizweni kuze kufike ekuchameleni (ejaculation) uyinqubo ehlelekile eqinisekisa ukuthi yiso kuphela isidoda esiqinile esinethuba lokufaka iqanda.

Okubalulekile ekugcineni

Ngokwazi ukuthi ukukhiqizwa kwesidoda kwenzeka kanjani emzimbeni kanye nomzila wesidoda kusukela ekuqaleni kuze kube sekugcineni, imibhangqwana ingaqonda kangcono izinto ezithinta ukukhulelwa. Ukwazana nomzila wesidoda kungasiza ekuqaphelweni kwezithiyo ezingaba khona nasekuthatheni izinyathelo ezisebenzayo zokwandisa amathuba okuba nenzalo. Indlela yokuphila enempilo, ukutholakala kusenesikhathi kwezinkinga ezingaba khona, nokuqondiswa kochwepheshe kungayithuthukisa kakhulu amathuba okukhulelwa ngempumelelo.

Imibuzo ejwayelekile

Uyini umzila wesidoda ngokulandelana?

Lo mzila uqala emasendeni, udlulele ku-epididymis, bese udlula ku-vas deferens, imithambo ye-ejaculatory, ekugcineni uphume ngomchamo wesitho sangasese sowesilisa (urethra).

I-spermatogenesis ithatha isikhathi esingakanani?

Yonke inqubo ye-spermatogenesis ithatha cishe izinsuku ezingu-64, bese kwengezwa ezinye izinsuku ezingu-14 ukuze isidoda sivuthwe ngokuphelele ku-epididymis.

Isidoda siqala kuphi uhambo laso?

Isidoda siqala uhambo laso emigudwini ye-seminiferous ngaphakathi kwamasende.

Inqubo yokukhiqizwa kwesidoda ibizwa ngokuthini ukukhiqizwa kubizwa ngokuthi?

Inqubo yokukhiqizwa kwesidoda ibizwa ngokuthi i-spermatogenesis.

Ngemva kwe-spermatogenesis, isidoda sigcinwa kuphi?

Ngemva kwe-spermatogenesis, isidoda sigcinwa ku-epididymis kuze kufike isikhathi sokuchama (i-ejaculation).
