Ukukhulelwa kwengane kanye nezimpawu zokukhulelwa kuyafana nanoma yikuphi ubudala. Umehluko wukuthi ngeminyaka ehlukene kunezinkinga zomphakathi. Isibonelo, ukukhulelwa kwengane esemncane (iminyaka engu-17-20) kuhlanganisa izinkinga eziningi. Kule minyaka yobudala, abazali baqhubeka bezinzile ezinyaweni zabo, abanakho amakhaya abo. Angakakulungeli ukukhulisa ingane, ngakho-ke badinga usizo oluvela kubadala, kokubili ukuziphatha nokuphathekayo.
Abashadile abaneminyaka engaphezu kwengu-20 baneminyaka engcono kakhulu yokubeletha. Bayiphilile, begcwele amandla. Ukukhulelwa nokubeletha kokubeletha kule minyaka kubesifazane ikakhulukazi ngaphandle kwezinkinga. Okuwukuphela kwenkinga ukuthi ngalesi sikhathi lo mbhangqwana osemusha awunaso isisekelo esiqinile sezinto ezibonakalayo. Owesifazane ufuna ukwenza umsebenzi, ngakho-ke akasenqume ukuba nomntwana esemncane.
Iminyaka engaphezu kwengu-30 yisikhathi lapho abashadile sebevele bafeze impumelelo emisebenzini yabo, bahlala beqinile, indlu yabo ifakwe. Ngakho-ke, manje imibhangqwana eminingi manje inquma ukuba nengane eneminyaka engu-35-40.
Ukukhulelwa kwengane kule minyaka kuhlotshaniswa nezinkinga ezihlukahlukene, kepha lokhu akuhlali njalo. Lapho abazali bebaneminyaka eminingi, ingozi enkulu yokukhulelwa ingane nge-chromosomal engavamile.
Ukukhulelwa kwengane kanye nezimpawu zokukhulelwa zilandelana. Ingane ikhulelwa kanjani?
Ukukhulelwa kwengane kwenzeka, ngenxa yokuhlanganiswa kwamangqamuzana omzimba wesilisa nowesifazane - iqanda nesidoda.
Ngesikhathi sokuvuthwa, i-ovum evuthiwe ivela emaqanda omfazi, okubangela ukuzalwa kwempilo entsha. Ekuqaleni, amaqanda asemgodini ogcwele uketshezi. Phakathi nomjikelezo wokuya esikhathini, iqanda livuthwa futhi selikulungele ukukhulelwa. Ngesikhathi sokulala ngokocansi, isibindi sabantu besilisa esingu-200-300 singena emzimbeni wesifazane, ohamba ngaphakathi kwezitho zangasese zangaphakathi zobulili. I-Spermatozoa ihamba isuka esiswini ukuya esibelethweni. Esigabeni somzimba, abesifazane besilisa bahamba ngenkuthalo ezinsukwini ezimbili. Iqanda, elitholakala ku-tube fallopian, lihlangana ne-spermatozoa elikumboza. Ukungena ngaphakathi kwe-egg spermatozoa kuqala ukufihla ama-enzyme ekwazi "ukubhoboza" igobolondo lalo. Ngenxa yalokho, i-spermatozoon eyodwa ivela ngaphakathi kweqanda leqanda. I-spermatozoa esele iyobhujiswa. Ngaphakathi kweqanda lamaqanda, i-membrane yesimiso iyancibilika, futhi ihlangana neqanda ngokwayo, yenza i-zygote-i-embryo e-unicellular. Njengoba i-embryo ikhula futhi ikhula, ihamba eduze kwe-tube fallopian ibe esibelethweni, lapho ihlanganiswe nodonga lwayo lwama-mucous. Lesi sikhathi sithatha isilinganiso sesonto.
Ngemuva kokukhulelwa kwengane, lona wesifazane unezibonakaliso zokukhulelwa, ezibonakala empilweni yakhe nenhlalakahle yakhe. Izibonakaliso zokuqala zokukhulelwa - ukulibaziseka esikhathini sokuya esikhathini, isicanucanu nokuhlanza, ikakhulukazi ekuseni, isifuba sebele.
Lokhu okulandelayo kuyimpawu zokukhulelwa:
- Ukukhathala okusheshayo;
- Ukuthukuthela;
- Ukufutheka;
- ukuzwela ngokweqile;
- ushintsho ekudleni (noma landa noma linyamalale ngokuphelele);
- izinguquko ezintandokazi zokunambitha.
Ngemuva kokuba unezibonakaliso zokuqala zokukhulelwa, kufanele uhlole ukukhulelwa ekhaya, okukuvumela ukuba uthole mayelana nokukhulelwa okuzayo ngesonto ngemuva kokuthi kwenzeke.
Uyajabula wena ukukhulelwa!
