"Mukomana kana musikana?" - mubvunzo uyu willy-nilly unozviti iwo mukadzi wose panguva yekuzvitakura. Vamwe vakaroora vanorota kuti mugari wenhaka, vamwe pamusoro pechikadzi chiduku, uye vamwe vanofarira kugamuchira chero sarudzo. Chero zvazvingava, mubvunzo wekuti "Ungaziva sei zvepabonde yemwana asati aberekwa?" Ndeipi yeiyo yakakurumbira kune vabereki munguva yemberi.
Kusvika iye zvino, kune maitiro e laboratory anokubvumira kuziva hutano hwemwana muchibereko. Mukuwedzera, vanhu vakasiyana-siyana zvinowanzoshandiswa zvikuru. Zvikanganiso mune tsanangudzo yekuita zvepabonde zvinowira mune zvose. Kubva munyaya ino uchadzidza kuti ungawana sei zvepabonde zvemwana wemwana achishandisa nzira dzakatendeseka.
Nzira yekuziva sei kurara kwemwana patafura?
Hazvisi mamimai emazuva ano chete ane chido uye anoda, sezvaanogona kuti azive zvepabonde revana vavo remangwana. Munguva yekare, vakadzi vaifarirawo nyaya iyi. Munyika dzakasiyana, vanaamai vekuuya vakagadzira nzira dzakasiyana dzekuziva kuti ndiani achazvarwa. Imwe yenzira dzakakurumbira dzekare, dzinoshandiswa nevakadzi vemazuva ano, ndiyo yekare yechina yekuita zvepabonde patafura.
Kwemazuva mazhinji, vagari vechiChinese vakacherechedza vakadzi vane pamuviri, vachifananidza makore emangwana amai uye nguva yekuita pamuviri, uye vakapedzisa kuti zvinhu zviviri izvi zvakabatana zvikuru. Kuziva nhamba yemakore akazara emumai panguva yekuberekwa uye mwedzi wekubata pamuviri, zvinokwanisika kugadzirisa nehupamhi hwepamusoro huchazvarwa. Tafura, kuti uzive sei zvepabonde yemwana asati aberekwa, inoratidzwa mumufananidzo. Muchikamu - nguva yeamai, mumutsara-mwedzi wokutora pamuviri. Kuziva izvi zviviri zviratidzo, iwe unogona nyore kuona kugona kwemwana.
Chiremba chekare chekuShayina chebonde revana remangwana chinyorwa chakare kwazvo chakawanikwa pedyo neBeijing makore anopfuura 700 apfuura. Tafura yakachengetwa mune imwe yematemberi, uye nhasi inogona kuonekwa muIsi Institute of Sciences yeBeijing.
Kubva patafura, tinogona kugumisa kuti vakadzi vane makore gumi nemasere vane mukana mukuru wekutora mukomana, muna 21 - musikana.
Nzira yekuziva sei kurara kwemwana neropa?
Iyi nzira haisi yekare seyetafura yeChina, zvisinei, inoshandiswa nevabereki munguva yemberi yezvizvarwa zvakawanda, izvo zvinoratidza kukwirira kwayo.
Masayendisiti akaratidza kuti ropa riri mumuviri womunhu rinoramba richivandudzwa. Uyezve, kutenderera kwekuvandudzwa kweropa kwakasiyana nevarume nevakadzi. Nyanzvi dzakakwanisa kuratidza kuti mumakore mana ropa rakazara zvachose kumunhu, uye kwemakore matatu - nokuda kwemukadzi. Kuita zvepabonde kwemwana weramangwana kunotsanangurwa nemubereki, uyo ane ropa panguva yekubata achiri muduku. Somuenzaniso, baba vevana remangwana vane makore makumi maviri nemana, uye amai 25. Ropa rababa vake rakapedzisira razorodzwa pazera remakore makumi maviri nemana (rakasara riri kuparadzanisa 28 ne4 ndiro 0), uye amai vari muna 24 (zvakasiyiwa apo kugovana 25 ne3 ndiko 1) . Saizvozvowo, ropa remunhu panguva yekuberekwa ruduku, iro nenzira iyi inotsigira mukomana.
Paunenge uchishandisa nzira iyi, zvakakosha kuongorora chero kurashikirwa kweropa rinokosha mukati mehupenyu hweumwe neumwe wevakaroorana - kuvhiyiwa, kuberekwa, kuwedzerwa ropa. Kana izvi zvikaitika, mharidzo inofanira kuchengetwa kubva musi wechiitiko ichi.
Nzira yekudzidzira sei zvepabonde zvemwana wemwana ne ultrasound?
Kusvika iye zvino, nzira ye ultrasound inonzi inonyanya kuvimbika uye yakavimbika yekugadzirisa zvepabonde. Vanaamai vakawanda vanotarisira vanofarira mubvunzo wokuti "Ndingaziva rini mwana wepabonde ne ultrasound?". Pamusana pemimba yose, mukadzi anotarisira hutachiona hutatu hwakagadzirirwa - pamasvondo 11-12, pamasvondo 21-22 uye masvondo 31-32. Iwe unogona kuwana hutano hwemwana ne ultrasound munguva yechipiri yakarongwa kudzidza. Mune dzimwe nguva zvisingawanzoitiki, nyanzvi inozivisa zvepabonde pane yekutanga ultrasound. Zvisinei, kana mwana akadzoka shure kwake kana kumativi panguva iyo nzira, kunyange amateur ane ruzivo rwakakwana haagoni kugutsa chido chevabereki venguva yemberi.
Zvinokwanisika kuziva hutano hwemwana musati vhiki yegumi nembiri kubvira pakuberekwa here?
Penguva yemavhiki 12-13, fetus inogumisa kuumbwa kwenhengo dzepabonde. Kunyange zvakadaro, tisati tasvika mavhiki gumi nemaviri kuti tiongorore pahwindo rekuona kuti zvepabonde zvemangwana kid zvinokwanisika chete kune vadzidzisi vane ruzivo. Kusvikira mavhiki masere ekuberekwa, hakuna munhu anogona kupindura mubvunzo uyu.
