Ukunquma ubulili wengane abazali lokuzalwa

Cishe wonke umuntu wesifazane ilindele umama ekuseni ifuna ukwazi ukuthi ungubani: umfana noma intombazane. Phela, ukucacisa ozozalwa, kungaba eduze phakathi nokukhulelwa (by ultrasound), futhi ngisho nangalesosikhathi ngaso sonke isikhathi. Futhi abaningi yakhetha ezihlukahlukene ukuqagela, Computing abazali ubudala, ikhalenda Chinese noma izimpawu kazwelonke, isibonelo, ekuboneni ubulili yefomu umntwana esiswini. Ngaphezu kwalokho, kukhona amasu ezimbalwa ezikusiza imibhangqwana nje kuphela ukufunda ubulili womntwana kusengaphambili, kodwa futhi ukuhlela ukuzalwa umfana noma intombazane. Kuyini lokhu indlela, siyathola kulesi sihloko.

Funda, futhi ngezinye izikhathi ngisho ukuhlela ubulili umntwana angasebenzisa indlela lapho kwencazelo ingane ubulili lokuzalwa kwenzeka. Kunalokho, ngokuvumelana lapho olusha igazi abazali. Kuyini lokhu indlela? Njengoba wazi, igazi lethu ngezikhathi olusha. Le nqubo kwenzeka njalo ngemva kweminyaka embalwa. In amadoda, inqubo izibuyekezo igazi zenzeka kanye njalo eminyakeni 4. Ngo umzimba female igazi olusha kanye njalo eminyakeni emi-3. Ngoba lokho isikimu zingenziwa sokunquma ubulili wengane ubuyekeze abazali igazi. Thatha ambalwa isilinganiso ngenhla, esesikhundleni amathathu nanhlanu ayizinkulungwane ezingamashumi amabili nesithupha futhi umyeni wakhe unkosikazi. Hlukanisa it zibe ezintathu ubudala futhi wakhe - ezine. Izinombolo etholwe 11.6 futhi 6.5. Ngesisekelo ibhalansi kungenziwa wagomela ukuthi Isibuyekezo sokugcina kwaba seduze ngegazi ukuze ukukhulelwa wengane yazalwa ngowesifazana, ngakho - banayo intombazane. Kodwa le ndlela aluphelele, kusukela igazi kungenziwa olusha futhi okwenziwe. Ngokwesibonelo, lapho umnikelo igazi, imisebenzi ahlukahlukene ukumpontshelwa enkulu nokopha futhi kwenze nalokunye kungenelela lineages Ungase futhi zenzeka update. Ngakho-ke, lapho kubalwa isidingo acabangele leli isici.

Futhi, zikhona izindlela ezimbili zingenzeka ukunquma ocansini wengane nge lwegazi. Omunye wabo - uyakucabangela iqembu, kanti eyesibili - RH. Uma umama nobaba ongakazalwa wengane omuhle noma omubi RH igazi ke intombazane. Uma RH isici lomama esizayo futhi oyise babehlukene (omunye wabo omuhle, futhi kwezinye - a negative) - uzothola umfana. Uma umama igazi lokuqala, futhi upapa - imoto yokuqala - intombazane, kwesibili - umfana, eyesithathu - intombazane, owesine - umfana. Iqembu wegazi ukubala kamama wesibili kwenziwa ngendlela efanayo, kodwa kunalokho, okungukuthi, uma umama anayo iqembu igazi yesibili, futhi uyise - ngowokuqala - umfana othile, kanti owesibili - intombazane, eyesithathu - neyesine umfana - intombazane. igazi likamama lingahlangani Okwesithathu futhi iqala umbiko wayo namantombazane. Kodwa uthemba le ndlela, njengoba ukuzimisela ubulili wengane ngegazi hhayi kungaba amaphesenti ayikhulu.

Indlela ethembeke kakhulu iwukuba ukunquma ocansini wengane ngegazi, esithathelwe ngowesifazane okhulelwe ukuba kwesonto lesikhombisa yokukhulelwa. iqiniso mayelana 99% wayo. Owesifazane okhulelwe uzodinga umane nje ukudlulise ku analysis olukhethekile igazi emthanjeni. Ingqikithi le ndlela kusekelwe yokuthi esegazini nokuthumba owesifazane owayezithwele, has inombolo encane amaseli fetus, futhi kunezinhlobo ezimbili lezakhi zofuzo ezisemangqamuzaneni womuntu. Yaziwa Kuyaphawuleka ukuthi owesifazane wabeka kuphela X chromosome, futhi indoda - X Y-chromosome. Futhi uma umphumela ukuhlaziya phakathi X chromosome egazini zesifazane uzothola okungenani oyedwa Y-chromosome, wayezoba umfana.

Ngaphezu kwalokho, kungenzeka ukukhiqiza incazelo ubulili wengane ngegazi, kukhona okubonwa abanye abantu abaningi sika, okuyinto bahlangana eminyakeni engaphezu kwekhulu. Ngokwesibonelo, lapho kuwuphawu lokuthi abafana zimatasa esiswini, noma isikhathi eside isikhathi phakathi ukubeletha owesifazane isidlulile, kunamathuba amaningi okuthi izingane kuzoba nabesifazane ezahlukene. Bathi intombazane ithatha ubuhle omama, ngoba nabesifazane abangabafundi abakhuthele namadodakazi ukhulelwe, zivame ukuba nezinkinga isikhumba ngesimo elula izimpawu, induna, ukuqubuka nokuvuvukala. Kukhona uphawu ukuthi abesifazane ababeye sikhulisa amantombazane akhangwa kakhulu sweet nofulawa. Futhi uma kwesisu bomfana, abakhulelwe ukudansela isiginci sakhe zonke ezimuncu, ezinosawoti futhi okubabayo.

Kunezinto eziningi izindlela ezehlukene imithi futhi abantu. Kodwa ngeke ukholwe ukuthi - kuphuma kuwe. Into esemqoka ukuthi umntwana enempilo.
