Inkwenkwe okanye intombazana? Uhlobo aluhlangabezane neemfuno zabazali. Abo bakholelwa ukuba amathuba okubeletha intombazana okanye inkwenkwe elinganayo ayilunganga. Akuzange nanini ukuba umlinganiselo phakathi kwamakhwenkwe namantombazana azalwe ngu-1: 1. Njalo umntu uzalwa ngokubanzi, omnye umntu ungaphantsi. Izinto ezininzi zichaphazela ukuguquka.
Ubunzima bomama ngaphambi kokukhulelwe lunempembelelo enkulu kwizesondo zomntwana. Abaphandi baseNtaliyane baphawula abafazi abakhulelweyo abayi-10 Iziphumo zibonisa ukuba abafazi abanesisindo esingaphantsi kwama-54 kg, bahlala bezala abafana kunabanye.
Ubulili bomntwana bunokuchaphazeleka ngamaphulo ahlukeneyo endalo kunye neentlekele zemvelo. Ngoko emazweni aphantsi kwesomiso kwaye, ngenxa yoko, indlala, amantombazana azalwa kabini kaninzi. Abaphandi baseMerika bafumanisa ukuba emva kwenkxalabo yokulala, indlala kunye nezinye iintlekele zemvelo ngokubanzi, kubalwa kakhulu abantwana abesilisa abesilisa.
Umgangatho wesidoda kunye nesondo leembrusi ayithinteli kuphela ukungondleki, kodwa kunye neminye imiba eyahlukeneyo. Iingcali ziye zaphawula utshintsho oluphawulekayo kumlinganiselo wamakhwenkwe namantombazana aseMpuma Jamani emva kokuwa kweBell Wall. Ngo-1991, bazalwa ngamakhulu angamawaka amakhwenkwe angaphantsi, kwaye izazinzulu zichaza oku ngokuthi ngoku unyaka abantu babechukunyiswa kakhulu phantsi kwefuthe lezinto ezithile-iimeko ezithile zezopolitiko. Emva kokuzamazama komhlaba kunye neentlekele zemvelo, inani labafana liyancipha. Ukuxinezeleka kwakhona kuboniswa njengesizathu esiyinhloko.
Umlinganiselo wesini uchaphazela ixesha. Xa ukhulelwe kwindla, amanye amakhwenkwe azalwa, kwaye amathuba okubeletha intombazana aphezulu xa ukukhulelwa kwenzeka ukusuka ngoMatshi ukuya kuMeyi.
Ama-embrosi ayenomntu anenzuzo kwinqanaba lokungena kwisibeletho. Iiseli zesibindi somntu zihlulwe ngokukhawuleza, kwaye zonke iinkqubo ezinxulumene nemetabolism zisebenza ngokukhawuleza. Kodwa ngokuhlukana ngokukhawuleza kweeseli, amathuba okuphuhliswa kokuphuhliswa kwenyusa. Umphumo weexin kunye nezinye izinto eziyingozi ziyanda. Ngaloo ndlela, ngexesha lokukhulelwa kwaye emva kokuzalwa emva kokuzalwa, amathuba okuphuhliswa okungavumelekanga kwamakhwenkwe aphezulu.
Oososayensi baqhubeka bephikisana nokuba isondo somntwana sincike ekungcolisweni komngcipheko wendalo, nokuba ngaba kuthinta umlinganiselo phakathi kwamantombazana namakhwenkwe azalwa. Abaphandi baseMerika baqinisekile ukuba ezi zinto zichaphazela umlinganiselo phakathi kwabantwana abatsha. Ngokomzekelo, iminyaka eyisixhenxe emva kwengozi ephathelele ukukhululwa kwe-dioxin kwindawo enobungozi, kwakukho intombazana eninzi emantombazana.
Ukuxhomekeka kwiimeko ezinxulumene nezinto ezithile sele sele zibonakaliswe yizinzulu. Ziyakuchaphazela umdaka kwaye zikhusele ukuphuhliswa kwembungu kumbele. I-Nicotine yenye yezinto eziyingozi. Abaphandi baseJapan nabaseDanish bafumanisa ukuba ukutshaya ngaphambi kokukhulelwe kwaye ngexesha lokukhulelwa kunciphisa kakhulu amathuba okuzalwa kwamakhwenkwe. Yaye ukuba ngaba abazali bobabini bayabhema, ithuba lokuzalwa kweentombazana liphakanyiswa ngenye yesithathu xa kuthelekiswa nabangabhemi.
