Uphindwa kabini uvuyo kumama. Nangona kunjalo, ukukhulelwa ngamawele kunokuba neenkalo ezininzi kunye neengxaki, kwaye kuninzi kwizinto ezikhoyo ngoku kuxhomekeke ekubeni ngaba amawele adala ukuhlukana kwesinye i-zygote kwiveki yesibini yokukhulelwa, okanye kuya kuba malunga nokukhulelwa kwamaqanda amabini ahlukeneyo okanye ukuhlukana kwangaphambili.
Iintlobo zamawele
Iimbini ezinezintlu ezine eziphambili ezinokuvela ngenxa yezimilo ezimbini zokukhulelwa. Uhlobo oluqala lokukhulelwa, olune-subtype olulodwa, luloliso lwe-ovules ezimbini ngexesha elifanayo. Ngenxa yoko, amawele e-bichorial diamiotic azalwa, ahlukeneyo ama-chorions kunye nama-omnions ahlukeneyo (afumaneka kuma-placenta ahlukeneyo kunye nakwamacaka e-amniotic ahlukeneyo). Iintsana ezinjalo zinokuba neentlobo ezahlukeneyo zesini kunye neembonakalo ezahlukeneyo.
Ukongezelela, kukho enye inguqulelo yokukhulelwa. Emzimbeni womama, i-ovum ripens kuphela, ehluthwa yi-spermatozoon enye, kodwa ngenxa yesahlulo ivelisa amaqanda amabini apheleleyo ngokukhawuleza. Ngokuxhomekeke kwimihla eyahlukana ngayo, ukwahlukana kweentlobo ezintathu zewele. Bangaba ne-chorion kunye ne-omnion, kodwa kuphela ukuba ukwahlukana kwenzeka ngokoqobo kwiiyure zokuqala ezingama-48-72 emva kokukhulelwa. Ukuba ukukhulelwa kwenzeka emva koko, banokuba neqhekeza eliqhelekileyo kunye nee-omionons ezahlukileyo okanye i-chorion eqhelekileyo kunye ne-omnion efanayo. Kwimizekelo emibini yokugqibela, amawele abizwa ngokuthi ayenjalo i-odnoyaytsevymi, baya kuba ngabafana besini kwaye baya kufana njengamaconsi amabini amanzi, kungekhona nje ngaphandle, kodwa kunye nesethi yama-chromosomes.
Amawele e-Bihorial
Iingcali zikholelwa ukuba ngamawele e-biamnotic kwimpilo kamama, kunye namawele ngokwawo, okuyiyona nto ikhethiweyo kakhulu ekuphuhlisweni kweemeko. Ngamaxesha amaninzi, kuthatha malunga ne-25-30% yenani lamawele. Iintsana zihlakulela ngokwahlukileyo komnye, zidla kwi-placenta ehlukeneyo, ngoko ke zilungelelaniswe zonke izinto eziyimfuneko ekukhuleni nasekuphuhlisweni. La mawele aqhelekileyo abe nomlinganiselo omncinci obunzima kwaye azalwa ngokuzele. Banobunzima obuncinci bokuphuhliswa kokukhula kunye neengxaki ezimbalwa kwixesha lokuhamba.
Ukongeza, ukukhulelwa kunomngcipheko omncinci weengxaki kumama. Kwezinye iimeko, ukuba iintsana zombini zilala ngokuchanekileyo, iingcali zingavumela umama ukuba abelethe ngokwabo, ngamanye amaxesha kwenzeka ukuba iintsana zizalwe nangomlinganiselo weentsuku eziliqela. Enyanisweni, abancinci ababini kumama ngumthwalo omkhulu, kodwa banonwabo olukhulu. Njengomthetho, ukuzalwa kwe- double dichorial ilifa, ngoko ukuba umama osentsapho sele esele ewele amawele, ngoko ke amathuba okuba aphethe amawele angamazinyo ayanda. Amawele e-Monochorionic angabonakala kuyo nayiphi na intsapho kwaye ixhomekeke kuphela kwinkqubo yokwahlukana kweintsana. Ezinye izinto zidlala indima apha.
Ukuchonga uhlobo olunjani lomama olusisigxina okanye i-monochorionic, lunokwenziwa kwisifundo esikhethekileyo, umzekelo, ngexesha le-chorionic okanye i- amniocentesis biopsy. Kwi-ultrasound yesiqhelo, fumana lo mbuzo
Namhlanje, iingcali ziyazi kakuhle ukuba ziphi na amawele, zinokumisela kwi-ultrasound ingcali, apho umama we-placenta ephindwe kabini okanye engatshatanga, kwaye uthetha ngendlela abantwana abakha ngayo kwaye ingaba baneengxaki ekukhuleni. Ukuba kuyimfuneko, umama angabelwa izidakamizwa ezikhethekileyo, eziza kumnceda ukuba athethe nabantwana bobabini.
