Lapho kumiswa ocansini wengane is esibelethweni?

Ukuzalwa kwengane - kuyisimangaliso, okuyinto ijwayelekile yilowo nalowo owesifazane osuke emhlabeni, eye uba umama. Ngamunye wabo ulinde lesi simangaliso futhi enethemba lokuthi kwaba ngomntanakhe kuyoba bajabule kakhulu, ohlakaniphile, yimpumelelo, uma ekhula. Futhi bonke omama abakhulelwe cabanga bangobani ukuchamisela: umfana noma intombazane.

"I inkukhu noma iqanda"?

Ngokwemibiko ye-nganekwane wasendulo mayelana uthando enhle, abantu Emhlabeni androgynous buphele, ayengamakhulu emncintiswaneni ephelele, ngokuhlanganisa izici kokubili iduna nensikazi. Amabutho asezulwini ihlukaniswe amadoda androgynous nabesifazane. Ukuze sithole lokho, hhayi okungaka, kodwa iqiniso liwukuthi kuze kube yilolu suku androgyne neengcezu ukufuna nomunye. Kushone owesilisa nowesifazane, eyathola umphefumulo wakhe womshado e nomunye futhi, laba bantu ababili abaphelele kakhulu, yomkhakha owodwa. Kodwa isintu sibhekene nenhlekelele phakade babe nabantwana, okuyinto ihlukaniswe yaba abesilisa nabesifazane, abafana namantombazane ozalwa.

Futhi bathini ngezakhi zofuzo?

Legend kuyinto enhle, kodwa izindlela ezintsha zesayensi zokufunda, izakhi zofuzo kanye nabasizi babo umkhakha uthi okuhluke ngokuphelele. Man uphelele endleleni, lo umehluko phakathi kobulili - akusiyo ngempela isijeziso sezono, kodwa isipho kusuka ngenhla. Phila futhi ezala zazo siqu - ukuqokwa wakho konke ukuphila eMhlabeni.

Okuningi inkambo esikoleni ukwakheka komzimba womuntu siyazi ukuthi amaseli ubulili banesibopho sokuqinisekisa ukuthi ukukhulelwa senzeka kwakhiwa, ukuthi lapho ubulili umntwana usesibelethweni, noma kunalokho, lapho kungenzeka kakade ukuba aqaphele. Futhi, kubonakala, Uma unganakile, yonke into icacile: endodeni kuxhomeke kulokho ucansi ingane kuyoba, kodwa mhlawumbe, phela akusiwona so simple?

Yini ubulili ingane ufuna?

Ukuze siphendule lo mbuzo: "? Benziwa kanjani kakhulu ubulili umntwana", Ingabe akwanele ukubalula kuphela ukuthi kwenzeka ngesikhathi ebamba isisu. Azikho amabutho ezizothinta ke, kungcono ungumfana noma uyintombazane, uma nje ebamba isisu selwenzekile kakade, kuyize zama ukushintsha, 'kuphazamise "enqubeni kokusebenzisa izintelezi, talismans, imithandazo, njll Futhi ngeviki kwakhiwa ubulili yengane, eqinisweni, akubalulekile, into esemqoka ukuthi ingane eze emkhayeni onothando.

Yiqiniso, ngaphambi nje ebamba isisu kufanele okungenani zama ukwenza konke okusemandleni ukuze ukwamukela indodakazi noma indodana uvele umndeni, kodwa yimuphi udokotela uzokutshela yiqiniso elisobala: ". Njengoba uNkulunkulu akuthandayo" Awakholelwa kunoma iyiphi amasu kanye nemishini zobuchwepheshe.

kokungenela Medical ngendlela efanele usaqala bekhulelwe ukuze yokukhetha sex kokubeletha

Okwazekayo, embryonic umjikelezo ukuthuthukiswa Isu efanayo ezibukwayo amasonto 11-12 - ukuhlukanisa umfana esizayo intombazane cishe kungenakwenzeka. Kunendlela eqolo ukwenza lokhu kusaqalwa kakhulu umbungu ukukhula. Kodwa umbuzo lapha akukho mayelana ngendlela yendabuko lokukhulelwa futhi mayelana kwesibeletho fertilization lapho esekhulile umzimba iqanda likamama elahlangana nesidoda kwakheka isidumbu sikayise, umzimba ixhunyiwe esebenzisa umama microsurgical. Futhi-ke, lapho ehlaziya amniotic fluid umbungu (okuyinto ngokuvamile kwephula igobolondo ayisivikelo umbungu, bese kuvela ingozi ukumlimaza khona, ngisho nakuba mncane) ukunquma ocansini wengane bese umbungu kwesokudla idluliswe esibelethweni esibelethweni. Kwamanye amazwe, le ndlela luqhutshwa, futhi uma amaphutha sokukhulelwa inqanyulwa, nezinye izindlela ezifana kunqatshelwe ngokomthetho ngenxa abangenasimilo futhi amoral aborting ngemibungu elingenacala okuyizinto ngenxa izibalo avumelekile amaphutha yezokwelapha awazange izingane.

Impendulo enembile kakhulu utawufundza US

Ultrasound luhlolo inquma lapho kumiswa ocansini wengane is, futhi ngempela ngokunembile, ngisho amasonto 12. Yiqiniso, kuyenzeka ukuthi uziolog okungalungile, kodwa nobuchwepheshe kadokotela akuvamile ehluleka. Nokho, akunakwenzeka ukuhlonza phansi amasonto 11 (ngenxa izici bokuphila) futhi emabangeni okugcina enkathi yokukhulelwa (ngenxa yokuthi i-fetus uyindawo enkulu futhi ukukhetha engela kwesokudla, anisuthi). Ngakho uma usafuna ukuthenga esizayo isipho kancane imibala nabangewona hlangothi, ultrasound kuzokusiza ukuba wenze isinqumo esifanele.

Kanjani ukukhulelwa?

Ingqamuzama ngayinye komama kanye zoyise Ama-chromosomes e umzimba iqukethe ngazimbili 46 (23 ngazimbili). Autosomes, okuyinto ethulwa inani 22 ngazimbili, banesibopho isethi zofuzo, lidlule kumzali siye enganeni. Futhi kuphela pair olulodwa - geterosomy - empeleni inquma ubulili umuntu.

amaseli Female neze kuthinte kumiswa ocansini umbungu. Ama-chromosomes e wakhe ucansi ziyafana, basuke kuboniswa XX ikhodi, kuyilapho chromosome ubulili besilisa babe chromosome amabii ahlukile XY chromosome pair. Ixhuma amaseli amabili akha ukwahlukahlukana zezakhi XX noma XY, okungukuthi, ngokoqobo, lokhu kusho ukuthi omunye owesifazane chromosome X, ixhunywe omunye chromosome besilisa Y noma X, kanye Kumiswa ubulili wengane ngesikhathi confluence amaseli, okungukuthi, ngesikhathi ebamba isisu. Futhi akukho okunye.

On the ubulili wengane Kumiswa by ngesonto?

Naphezu kweqiniso lokuthi (kwakhiwa Imininingwane kulokho leligama ubulili wengane physiologically, kunalokho ezingacacile, kukhona idatha kusuka amasonto 10 nangaphezulu langempela umehluko ngobulili embryo ngaphambi kwamasonto angu-10 lapho amasonto 16 okukhulelwa), akusho ukuthi i-embryo phambi kwalesi sikhathi sexless, futhi akwazi ukuba ngisho njengoba umfana nentombazane. Uma ngesikhathi copulation iqanda nesidoda zakwazi amaseli ezimbili ngelinye ilanga uyoba zygote olulodwa, okuyinto ihlukaniswe yaba izingxenye ezimbili ekupheleni kosuku lokuqala.

Izindlela ethandwa sokunquma ubulili umntwana

Kusukela ezikhathini zasendulo, abantu besifazane zibangela ukudideka kulabo ingane lokho ubulili basuke ukuchamisela. Ngezinye izikhathi esasikudinga sasikuthola ngenxa ilukuluku zabela ngomgubuzelo imfihlakalo phezu isimangaliso esikhulu - isimangaliso sendalo. Ngezinye izikhathi ukhathazekile sengqondo bendabuko izindlalifa - emazweni abashumayela Islam, futhi lesi simo sengqondo namuhla akayikhohliwe. Ngakho-ke, ngaleso sikhathi kumiswa ocansini wengane is esibelethweni, owesifazane oye wadida ikusasa lakhe.

Paul izingane ongakazalwa wazama ukufunda, futhi ngaphambi kokukhulelwa (ukubikezela ke). Umkhuba eminyaka ubudala ka ngokuchaza sokukhulelwa zihlanganisa izindlela sokunquma ubulili wosana ukuziphatha abesifazane, ngisho iqiniso ukuthola sokukhulelwa ngesikhathi owesifazane enezinwele imfihlo yakhe. Bancika izinguquko ngokubukeka kwakhe, Gait, lesikhumba noma ukuvuvukala anda. Namuhla, umuntu angabona ngokuvamile ukuzwa ukuthi intombazane esibelethweni kwenza unina esizayo ngaphansi kukhanga kunanoma umfana. Futhi ukuchaza lokhu okwashiwo kungaba ngempela kwezokwelapha: ngoba intombazane udinga ama-hormone ezifanayo ukuthi kukhona umthombo ubuhle kunina.

It is wayevame ukuthi ubulili womntwana kungenziwa kunqunywa ukuma esiswini kukamama esizayo. Uma ekhulelwe engabonakali kusukela emuva, Sisu ngombala hhayi kudedelwa, kulindelekile umfana, lapho kubonakala kusukela emuva noma izinhlangothi roundness ensimbi kuhluke ngaphezu imigqa esithambile futhi ushintsho bushelelezi kusukela esifubeni kuya ethangeni, intombazane. Kodwa umkhuba akunjalo, ngisho wesifazane efanayo zingavela ngesikhathi sokukhulelwa ngezindlela ezihlukene kakhulu, ukuhlakulela izingane bobulili obufanayo.

A omama yesimanje, abangakwazi uzizwe izingane zabo bese ukhuluma ngokwengqondo kubo, ukwethemba uxhumano zabo ikusasa umntwana, futhi lapho obumba phansi umntwana ongakazalwa, silalela kanjani sibhekiswe - njengoba indodana yakho noma indodakazi.

Izibikezelo futhi ukuqagela mayelana nokuthi ubani ulinde emkhayeni

amathekniki ahlukahlukeneko nokubhula ngaphambi kokukhulelwa isithembiso ukunemba umphumela. Futhi yize wonke umuntu uyazi ukuthi kwakhiwa phansi ingane, imfihlakalo izenzakalo eliyimfihlakalo the ukuphila edonsela Ifana nozibuthe. Technique pendulum okwesikhashana ngenhla entendeni, ilula: uma inaliti (tikhatsi tetifundvo, elengayo) uzungeza othize embuthanweni, emkhayeni kuyoba uyintombazane, uma wahosha emuva naphambili - umfana.

Ochwepheshe ukubhula ngokufunda intende bathi emigqeni lungacacisa inombolo izingane ongakazalwa ohlangothini kobuso uhlangothi, ukubhula zisebenzisa izinombolo futhi itafula ngokulandelana kwezinhlamvu zamagama ukunquma ezimbalwa ingane, njengokuba nazi inyanga nje ebamba isisu. Kodwa musa bawubheka njengobalulekile izibikezelo. Njengoba ihlaya ethandwa, amathuba ukubulawa ukubikezela lapho kumiswa ocansini wengane is, amaphesenti ayisihlanu noma kufezeke noma cha.

Izindlela lokukhulelwa ingane ubulili ethile

Kukhona amasu abaningi bathembele:

• inyanga amakhalenda ahlukahlukene nokubala;

• Ukudla for ebamba isisu;

• Budy indlela esekelwe amatafula idatha ukunquma isikhathi esingcono lokukhulelwa ingane yomuntu wesilisa noma wesifazane;

• indlela igazi okusekelwe silinganiso ubudala kamama ngesikhathi sokuhlala kwesisu;

• indlela igazi isekelwe esimisweni wegazi yokulungiswa amadoda njalo ngemva kweminyaka emine, futhi abesifazane - kanye ngeminyaka emithathu.

Kodwa kuzo zonke zazo kukhona amaphutha, ukukhubazeka (isib, iwele lokuzalwa isimo noma okuphambene-ubulili amawele, ezintathu, njll uhlukanise zalezi zinkolelo-mbono kuze nines). Imfundiso kuphela, nakuba amanzi amaningi indlela ukubambelela - indlela nge-ovulation.

Iqiniso lokuthi isidoda ukuphila ngazo izinsuku eziningana, futhi chromosome Y, okuyinto ezimbalwa esebenzayo nokuncane "olukhuni", obangela kweqanda we umfana othile, kanti-X chromosome, okuyinto, nakuba kancane, kodwa hardier, uhlala esiqeshini zangasese abesifazane ukuba izinsuku ezintathu. Ngakho-ke, uma ufuna ukuba akhulelwe umfana, akhulelwe Swayipha ngokuqondile ngesikhathi nge-ovulation (kuthatha cishe usuku). Futhi uma ufuna ukuba akhulelwe intombazane, kufanele uyeke nje ngalesi sikhathi ukuba alale naye, futhi ucabangele esifanele izinsuku ezintathu ngaphambi ukukhiqizwa kwamaqanda.
