Yintoni ukuqala ukutshatyalaliswa kwaye iqala njani?
Igama lokushicilela lithathwe kwigama lesiLatini elithi "puber" elithetha umntu omdala.
Ukutshatyalaliswa yixesha elisetyenziswe ukuchaza iminyaka apho umzimba wentombazana iqhutyelwa kutshintsho kwi-physiological adult. Uchungechunge lweenguqu lwenzeka emzimbeni. Olu tshintsho lubangela ukuphuhliswa ngokwesondo, ukuhluka komzimba kunye nokunyuka kokuphakama.
Kwakhona, eli lixesha xa intombazana iqala ukukhula ngokomoya.
Umzimba wakhe awutshintshi nje indlela ukhangeleka ngayo kodwa uguqula nendlela osebenza ngayo. Ngethuba lokutshatyalaliswa xa intombazana iqala ukuya esikhathini .
Ubushushu buqala xa inxalenye yengqondo yentombazana ebizwa ngokuba yi-hypothalamus iqala ukuvelisa ihomoni ebizwa ngokuthi i-GnRH (i-gonadotropin-release hormone). Xa i-hypothalamus iqala ukukhulula le hormone kwipatheni ethile ebizwa ngokuthi "iphethatile pattern" ibangela esinye isakhiwo kwisiseko seengqondo ezibizwa ngokuba yi-poriitary gland ukuvelisa izinto ezibalulekileyo ezibizwa ngokuba yi-FSH (i-follicle stimulating hormone) kunye ne-LH (i-hormone ye-luteinizing ). Ezi zinto ezibizwa ngokuthi i-gonadotropins zikhuthaza ama- ovari ukukhulula i-estrogen kunye ne-progesterone.
Inkqubo yobuntshintsho inezigaba ezahlukeneyo. Kwimantombazana, olu tshintsho luqala phakathi kweminyaka eyi-8 kunye neshumi elinanye. Amanqanaba okubaluleka achaza utshintsho olwenzeka kumzimba wentombazana.

Ngoko nje emva kokubonakala kwebhokhwe kwebhola intombazana yokuphakama iya kuqala ukunyuka kwixesha elikhawulezayo kunokuba lincinane. Ngexesha elithile ekufikeni komntwana, intombazana iya kuba nokwanda ngokukhawuleza ekuphakameni kwayo, oku kudla ngokuba kubizwa ngokuthi "ukukhula kancinci." Oku kwenzeka njalo emva kweenyanga ezimbalwa ngaphambi kokuba iqela leqabane liqale.
Xa intombazana iqala ezo ntshintsho kwaye ixesha elide le nkqubo ithatha ngayo intlobo kwiintombazana ukuya kwintombazana.
