Abesilisa baqala ukukhiqiza isidoda eminyakeni emingaki? Umhlahlandlela wokufikisa

Ukukhiqizwa kwesidoda kuyinto enkulu ekuzaleni kwendoda. Le nqubo ivame ukuveza imibuzo enjengokuthi, ukukhiqizwa kwesidoda kuqala eminyakeni emingaki, noma ngabe amadoda azalwe nesidoda yini? Umbuzo ovame kakhulu uthi, "eminyakeni emingaki amadoda angakwazi ukukhiqiza isidoda?"

Amadoda baqala ukwenza isidoda lapho befika ebudodeni, imvamisa phakathi kweminyaka engu-9 no-14 [1]. Ukufikela ebudodeni yisikhathi lapho abafana beqala ukubona izinguquko ezivelele njengokukhula kweenwele ebusweni, ukwakha imisipha eminingi, nezinye izinguquko zomzimba [2].

Lezi zinguquko zenzeka ngoba umzimba uqala ukukhiqiza i-testosterone eningi, okuyihomoni eyinhloko yobulili besilisa. I-testosterone ivusa ukukhiqizwa kwesidoda ngesikhathi sokufikela ebudodeni [3]. Lokhu kukhiqizwa kuyaqhubeka impilo yonke yendoda, kodwa ikhwalithi nenani lesidoda kungashintsha njengoba ikhula.

Kuyini Ukufikela Ebudodeni?

Cishe wonke umuntu uyayazi incazelo elula yokufikela ebudodeni, kodwa abanye abantu abakayiqondi kahle yonke imigudu yokushintsha indoda edlula kuyo ngemuva kokufikela ebudodeni. Abantu abaningi bazithola bezibuza, ngabe amadoda akhiqiza isidoda ngaphambi kokufikela ebudodeni?

Ub pubertynkathi empilweni yawo wonke owesilisa lapho umzimba wakhe uqala ukushintsha futhi ukhule ube njengomuntu omdala. Lokhu kuvamise ukwenzeka phakathi kweminyaka engu-9 no-14. Ihomoni ye-testosterone iyanda ngesikhathi sokufikela ebudodeni, ibangele izinguquko ezifana nokujula kwezwi, ukwanda kweenwele emzimbeni nasebusweni, nokukhula kwemisipha.

Amasende nawo aqala ukwenza isidoda, okusho ukuthi abafana sebeyakwazi ukuzala. Ngamafuphi, izinguquko zobufikayo ziphawula ukuqala kohambo lokuzala kwendoda.

Ukukhiqizwa Kwesidoda Kuqala Nini?

Imibuzo mayelana nesikhathi sokuqala ukukhiqizwa kwesidoda ivamile, futhi kungenzeka ukuthi uke wahlangabezana nemibuzo efana nokuthi, eminyakeni emingaki abafana baqala ukukhiqiza isidoda, noma eminyakeni emingaki umfana engazala ngazo?

Ukukhiqizwa kwesidoda kubafana kuvamise ukuqala phakathi kweminyaka engu-9 no-14. Lona yisikhathi lapho imizimba yabo ikhiqiza i-testosterone eningi, evusa ukuthuthuka kwezitho zokuzala, kuhlanganise namasende. Uma amasende esevuthiwe, aqala ukukhiqiza isidoda [4].

Into eyodwa ebalulekile okufanele uyikhumbule lapha ukuthi iminyaka yobudala bokufikela ebudodeni ayifani kuwo wonke umfana, ingahluka. Ubufakazi bokuqala bokukhiqizwa kwesidoda ngemuva kokufikela ebudodeni yilezi zikhishwa ebusuku, ezaziwa kakhulu ngokuthi "wet dreams" [5].

Inqubo Yokukhiqizwa Kwesidoda

Ukukhiqizwa kwesidoda kwenzeka emasende ngenqubo ebizwa ngokuthi i-spermatogenesis. Nansi indlela esebenza ngayo:

• Ama-spermatogonia: Ama-spermatogonia ngamangqamuzana esidoda angakavuthwa akhula abe isidoda esivuthiwe ekupheleni komjikelezo wokukhiqizwa kwesidoda.
• I-spermatogenesis: I-spermatogenesis ngumjikelezo wokukhiqizwa kwesidoda othatha izinsuku ezicishe zibe ngu-64. Kulo mjikelezo, ama-spermatogonia angakavuthwa adlula ochungechungeni lwezinguquko. Ngemva kwezinsuku ezicishe zibe ngu-64 kuya ku-74, ama-spermatogonia ekugcineni aba amaseli esidoda avuthiwe ngokuphelele [6].
• I-testosterone: I-testosterone iwuhomoni oyinhloko wocansi wamadoda okhiqizwa ezindlaleni zamadoda. Lo homoni uyona nto enkulu ngemuva kwenqubo ye-spermatogenesis. I-testosterone ithuthukisa isidoda futhi iqinisekisa ukuthi siqhubeka sikhiqizwa njalo.

I-spermatogenesis iyaqhubeka phakathi nokuphila kwendoda ngemuva kokuthomba, nakuba ikhwalithi nenani lesidoda kungashintsha njengoba iminyaka ihamba.

Izinto Ezithinta Ukuqala Kokukhiqizwa Kwesidoda

Iminyaka lapho ungaqala ukukhiqiza isidoda incike kulezi zinto ezilandelayo:

• Ufuzo: Iminyaka lapho umfana eqala ukukhiqiza isidoda kakhulu incike kakhulu kofuzo [6]. Uma abazali bomfana noma amalungu omndeni wabo beba nokuthomba kusenesikhathi noma sebedlulelwe isikhathi, yena angase abe nesikhathi esifanayo sokuthomba.
• Ukudla: Ukudla okunempilo kudlala indima enkulu ekuthuthukisweni komzimba jikelele, kuhlanganise nokuthi ukuthomba kuqala nini. Ukungondleki noma imikhuba emibi yokudla kungabambezela ukuthomba.
• Impilo Nendlela Yokuphila: Izimo ezifana nokukhuluphala ngokweqile noma izifo ezingapheli zingathinta ukuthi iminyaka emingaki lapho isidoda siqala ukukhiqizwa. Lokhu kungenxa yokuthi impilo nendlela yokuphila zingathinta amazinga amahomoni futhi zibambezele ukuthomba. Ukuhlala usebenza futhi unempilo kungasiza abafana badlule esigabeni sokuthomba ngeminyaka evamile. Nakuba ukudla nendlela yokuphila kubalulekile, kufanele futhi kuphawulwe ukuthi izinto zangaphandle, njengokushisa, zidlala indima, njengoba ukuvezwa ngokweqile ekushiseni kungavusa ukukhathazeka mayelana nokuthi ukushisa kuyabulala yini isidoda kanye nemiphumela yakhona ekuzaleni.

Ukukhiqizwa Kwesidoda Ngokuhamba Kobudala

Ukukhiqizwa kwesidoda akuyeki noma nini uma sekuqalile ngesikhathi sokuthomba. Noma yize ikhwalithi yesidoda nempilo yesidoda kwendoda kungase kwehle njengoba ikhula, ukukhiqizwa kuyaqhubeka. Izinto ezifana nengcindezi, ukudla, ukuzivocavoca, nezinketho zokuphila ezifana nokubhema noma ukusebenzisa utshwala nazo zingathinta ikhwalithi yesidoda ngokuhamba kwesikhathi. Ukugcina ukudla okulinganiselayo nendlela yokuphila enempilo kungenza umehluko omkhulu, futhi ukwengeza izithasiselo ezisekela ukuzala ezinokudla okubalulekile kungasiza futhi ekuthuthukiseni impilo yokuzala.

Ubudala bungenza umehluko ekunyakazeni kwesidoda nakwesimo sesidoda futhi [7]. Lezi yizinto ezibalulekile ekuzaleni, kodwa ngokuphila ngendlela enempilo, ikhwalithi yesidoda ingagcinwa.

Izinganekwane Ezivamile Ezihlobene Nokukhiqizwa Kwesidoda

Kukhona imiqondo eminingi engalungile nezinganekwane ezihlobene nokukhiqizwa kwesidoda nokuthomba kwabesilisa. Ezinye ezivamile zifaka phakathi:

Inganekwane 1: Ukukhiqizwa kwesidoda kuqala ngeminyaka efanayo kubo bonke abafana

Ukukhiqizwa kwesidoda kuqala lapho umfana efa ebudaleni bokuthomba. Ukuthomba kuyahlukahluka kakhulu, kuvame ukuqala phakathi kweminyaka ewu-9 nele-14. Abanye abafana bathomba kusenesikhathi noma sebedlulelwe isikhathi, kuya ngokufuzwana nakwezinye izinto.

Inkolelo-mbumbulu 2: Indoda ikhiqiza isidoda esekhwalithi efanayo impilo yayo yonke

Nakuba ukukhiqizwa kwesidoda kungayeki, ikhwalithi yesidoda ingancipha. Ezinye zezinto ezivamile ezibamba iqhaza ekonakaleni kwekhwalithi yesidoda zifaka iminyaka, indlela yokuphila, ukudla, nezimo zempilo. Izinto ezifana nokubhema, ukudla okungelula, noma ukucindezeleka zinganciphisa ikhwalithi yesidoda esikhathini eside.

Inkolelo-mbumbulu 3: Amadoda adinga ukukhulula isidoda ukuze agcine ukukhiqizwa kwesidoda

Umzimba wakho uqhubeka ukukhiqiza isidoda kungakhathaliseki ukuthi ukhipha isidoda njalo kangakanani. Uma ukhipha isidoda kaningi, kwehla okwesikhashana kuphela inani lesidoda ngakunye okukhiphwayo. Umzimba wakho uphinde ugcwalise isidoda ngemva kwesikhashana noma ngosuku olulandelayo.

Okufanele Ukhumbule

Impendulo embuzweni ethi, abesilisa baqala uneminyaka emingaki ukukhiqiza isidoda ukuthi umzimba wendoda uqala ukukhiqiza amaseli esidoda phakathi kweminyaka engu-9 kuya ku-14. Lona yilo mzuzu lapho umfana efika esikhathini sokuthomba futhi eqala ukuthuthukisa nezinye izimpawu zobudoda kanye nokukhiqizwa kwesidoda.

Iminyaka eqondile lapho umfana eqala ukukhiqiza isidoda futhi eba nokukhipha isidoda kokuqala ebusuku ingahluka. Izinto ezingathinta iminyaka yokuqala ukukhiqizwa kwesidoda kanye nekhwalithi yesidoda esikhathini eside zihlanganisa ifa lemvelo (genetics), ukudla, nendlela yokuphila.

Imibuzo Ebuzwa Kaningi

1. Abafana baqala ukukhiqiza isidoda baneminyaka emingaki?

Iminyaka lapho abafana beqala ukukhiqiza isidoda iyahlukahluka, kodwa ngokuvamile iphakathi kweminyaka engu-9 kuya ku-14. Lesi sigaba sibizwa nangokuthi yisikhathi sokuthomba.

2. Kukhiph’ kanjani isidoda uneminyaka engu-9?

Abesilisa bavame ukufinyelela esikhathini sokuthomba bebanga leminyaka engu-9 kuya ku-14. Ukukhiqizwa kwesidoda kuvame ukuqala ngemuva kweminyaka engu-9, futhi ayikho nhlobo inani lesidoda ongaphuma ngalo eneminyaka engu-9.

3. Amadoda ayeka nini ukuba nenzalo?

Amadoda aqala ukukhiqiza isidoda ngesikhathi sokuthomba, futhi aqhubeka nokwenza amaseli esidoda emavendeni awo kuyo yonke impilo yawo. Ukukhiqizwa kwesidoda akumisi ngaphandle uma kunenkinga yezempilo ethinte ukukhiqizwa kwesidoda.
