Ubusana bokuqala buchaphazela amantombazana kunye namakhwenkwe ngokwahlukileyo ngeendlela ezininzi. Nazi ezinye zeentlukwano ezinkulu zesini ezihlobene nokugqithisa kwangaphambili.
Ukukhula
Amantombazana akwazi ukufumana ukutshatyalaliswa kwasekuqaleni kunabesana. Isizathu esibalulekileyo solu phawu kukuba amantombazana ahlala ebusheni ngaphambili kunokuba amakhwenkwe ngokuqhelekileyo. Amantombazana abonisa kwakhona uluhlu oluninzi lokuqalisa ukutshatyalaliswa kwentsha (iminyaka eyi-9-16 yobudala ngokubhekiselele kwiminyaka eyi-13 ukuya kweyi-15 ubudala kubafana), okwenza okokuqala kunokwenzeka.
Isizathu
Xa amakhwenkwe afumana amava ngaphambi kobuntwaba, kaninzi akubangelwa ngenxa yezizathu ezininzi zeengqondo eziye zafunyanwa kumantombazana. Endaweni yoko, abafana banokuthi babe nezona zizathu ezibalulekileyo zokubeleka kunobantwana. Ngokukodwa, amakhwenkwe athathaka ngokusasazeka ngokuqhelekileyo ayenokungaqhelekanga kwinkqubo yabo ye-endocrine, njengemiba ene-adrenal gland okanye i-testicular function.
Uhlobo lweempembelelo
Kwiminyaka emininzi abaphandi babecinga ukuba abafana bafumana inzuzo ukususela ekufikeni kwexesha lokuqala xa abantwana beba nemiphumo emibi ekukhuliseni kwangaphambili. Ngokukodwa, izazinzulu zazikholelwa ukuba abafana baxhamla uluntu ekuhlaleni ngokwenyama ngenxa yokuba banokubonwa njengabaholi phakathi koontanga. Ngokwahlukileyo, intombazana inokuziva ihlazo ngenxa yeengcingo zawo zangaphambili kwaye ungenakujamelana nokuqhubela phambili ngokwesondo . Nangona le ngcamango ingaba yinto echanekileyo, uphando lwangoku lubonisa ukuba abafana abaye baqala ukukhulelwa babenamazinga okwanda kwengqondo kunye nokulungiswa kwengxaki xa kuthelekiswa neontanga zabo eziqhelekileyo, njengamantombazana asetshenzayo.
Ngamanye amazwi, abafana ababonakala bengenelwa nje ngokusukela ebusheni xa abantwana behlupheka.
Ubunzima
Nangona kubonakala ngathi amakhwenkwe afumana iimiphumo ezimbi ngenxa yobushushu obunobuncwane, imiphumo ayibonakali njengento engafanelekiyo njengoko iyenzela amantombazana. Ngokomzekelo, amakhwenkwe aqala ukukhula awanakuchukumisa iziphumo ezinzima njengengxaki ephazamiseka kwengqondo, ngelixa abantwana beselula bekhula.
Ukongezelela, abafana abafumana ukutshatyalaliswa kwangaphambili kubonakala bebalekela imiba ebandakanya umzobo womzimba, ukuzithemba , kunye neemfundo ukuba amantombazana asekhulile ahlale ekhula.
