Ucwaningo oluningi luye lwafakazela ukuthi ukuba ubaba kwehlisa amazinga e-testosterone egazini lamadoda. Ngemva kokuzalwa komntwana emndenini, umsebenzi wocansi uyancipha, ngakho-ke ukunamathela emndenini kuyanda, futhi obaba abancane abahambi ngakwesobunxele. Kodwa-ke, isazi sokusebenza kwengqondo saseNyuvesi yaseMichigan uSari van Anders uphikisa ngenye indlela. Akangabazi imiphumela yabalingani bakhe, kodwa ugcizelela kuphela ubuhlobo obuyinkimbinkimbi phakathi kwamahomoni kanye nesimo esithile lapho umuntu angase azithole khona.
“Ngokuya ngomongo nokuziphatha kwethu, izinguquko ezihlukahlukene zamahomoni zingabonwa. Lezi zinto zixhunywe amaphethini ayinkimbinkimbi kakhulu. Ngezinye izikhathi ezimweni ezimbili ezifanayo, ukukhuphuka kwama-hormone egazini kungenzeka ngezindlela ezihluke ngokuphelele. Kungase kuncike ekutheni lowo muntu usibona kanjani lesi simo,” kuchaza umcwaningi. “Lokhu kuyiqiniso ikakhulukazi ngobubaba, lapho sibona ukuhlukahluka okumangalisayo kwezindlela zokuziphatha,” wengeza.
Ukuze abone ukuthi ukukhishwa kwehomoni kuzokwenzeka kanjani esimweni ngasinye, u-van Anders wanquma ukwenza ucwaningo. Ulingise izimo ezine ezahlukene lapho umlingiswa obengunodoli wengane. Zivame ukusetshenziswa emakilasini esikole esiphakeme saseMelika ukufundisa intsha indlela yokusebenzelana nezingane. Unodoli angakhala ngokwemvelo futhi usabela lapho ethintwa.
Ukuhlolwa kwakubandakanya amavolontiya angama-55 aneminyaka engu-20. Ngaphambi kokuhlolwa, badlulisa amathe ukuze ahlaziywe ukuze kutholakale izinga le-testosterone, ngemva kwalokho bahlukaniswa ngamaqembu amane. Eyokuqala yayilula kakhulu. La madoda avele athula isikhashana esihlalweni, ebuka omagazini. Sebewuqedile lo msebenzi olula, baphinde badlulisa amasampula amathe bagoduka. Leli bekuyiqembu lokulawula.
Iqembu lesibili kwadingeka liphathe unodoli omncane owayehlelelwe ukuba akhale imizuzu engu-8. Kwakungenzeka ukuthulisa ingane kuphela ngokufaka isongo sezinzwa esandleni sakhe futhi simnyakazise ezingalweni zakhe. Iqembu lesithathu labhekana nobunzima: abazange banikezwe isongo. Ngakho-ke, kungakhathaliseki ukuthi amadoda ayezama kangakanani, umntwana akazange ehlise umoya. Kodwa abantu beqembu lokugcina babelinde ukuhlolwa okunzima kakhulu. Unodoli awuzange unikezwe kubo, kodwa waphoqeleka ukuba ulalele ukukhala, okuyinto, ngendlela, eyayingokoqobo kakhulu, kurekhodi. Ngakho-ke balalela izililo, kodwa behluleka ukwenza lutho. Ngemva kwalokho, wonke umuntu wadlula amathe ukuze ahlaziywe.
Imiphumela yaqinisekisa umbono kaSari van Anders. Ngempela, ezimweni ezintathu ezihlukene (namanje asicabangi eyokuqala), kwakukhona amanani ahlukene e-testosterone egazini lezifundo. Labo abahlulekile ukuthulisa umntwana abazange babonise izinguquko ze-hormonal. Amadoda anenhlanhla, okuthe ingane yathula ezandleni zawo, yehla ngo-10%. Ngenkathi abahlanganyeli abavele balalele ukukhala amazinga abo ehomoni besilisa eqa ngo-20%.
“Mhlawumbe lapho owesilisa ezwa ingane ikhala, kodwa ingakwazi ukusiza, kuqalwa ukusabela okungaqondakali engozini, okubonakala ngesifiso sokuvikela ingane. Kulokhu, ukwanda kwe-testosterone akuhlobene nokuziphatha kocansi, kodwa nokuphepha,” kuphakamisa u-van Anders.
