Vamwe vanoedza kufungidzira pamuviri uye, maererano naizvozvo, kuberekwa kwemwana asati aberekwa kumwaka unodiwa kana kunyange rimwe zuva. Zvisinei, sezvamunoziva, munhu anotora, uye nguva yakaitika, uye mwana wako achazvarwa chete paanenge achida, uyewo kana iwe wakagadzirira.
Munguva iyi, mukana wekuberekwa kwomwana zvakananga kunobva pane hutano hwevamwe, uye, kunyanya, mararamiro emukadzi pakuenda kumwedzi. Muchikamu chino tichazotaura nezvemazuva api ekutenderera zviri nani kuita zvepabonde, kuitira kuti ave nepamuviri, uyewo kana zvichibvira kufungidzira hutano hwemwana ari mberi mune izvozvi.
Maitiro ehupenyu hwemudzimai mumwe nomumwe akarongwa kuitira kuti mazuva maviri chete mumwedzi mumwe nomumwe ave akanaka pakubata pamuviri, kureva, nguva yekuvhara. Uye kukanganisa kwakasiyana-siyana kwehutano hwevakadzi kunogona kutungamirira mukushayikwa kwehuputi panguva yekuenda kumwedzi, uye naizvozvo, kukwanisa kutora pamuviri.
Nzira yekuziva sei nguva yekuputika?
Mukadzi anoda kuve nevana, zvakakosha kusvika kwemwedzi mitatu kuti aone mazuva ekufamba kwake panguva yokuenda kumwedzi kuti aone mazuva ari nani kubata mwana. Nenguva dzose, mavhiri anoitika mukati maro mukati uye haagari mazuva anopfuura matatu. Zvisinei, nokuda kwekubata pamuviri, mazuva maviri anofanirwa kusati yatanga kubuda, nokuti spermatozoa inogona kuramba ichishanda kwenguva yakareba, ichimirira kusunungurwa kweii yakakura.
Vamwe vasikana munguva yehuvhuti vane malaise anononoka, zvishoma zvinokonzera marwadzo mudumbu rezasi, kubuda kwechikadzi kunogona kuwedzera. Zvisinei, ndiyo mazuva awa ayo mukadzi anowana chido chikuru chekuita rudo.
Muchiitiko chekusagadzikana kwepakati, zviri nani kushandisa nzira yekusimudzira yekutengesa - mumazuva ekutanga kwekuvhura kwehupamhi huchava hukuru hwepamusoro. Zvisinei, zvinotokoshawo kuti uzvienzanise, zvichida kwemashoko maviri, kutora mhinduro mune imwe tafura chaiye.
Chii chinogadzirisa kurara kwevana munguva yemberi?
Mikana yekuberekwa kwomwana kwepabonde chaiyo zvakananga kunobva pane rudzi rwemhombwe. Panguva yekuita zvepabonde, varume vanokura spermatozoa yemhando mbiri-X uye Y. Rudzi rwekutanga runo musoro wechipfuva, simba guru uye hupenyu hurefu, asi zvishoma. Y-spermatozoa ane musoro wakakomba aripo mumurume wemurume mune zvinopfuura X, asi zvinoshamisa zvisinganzwisisike uye anofa zvikuru kare.
Vanosarudza kurara kwevana remangwana - kana X-spermatozoon yakabatana neiyo masero, musikana achazvarwa, uye kana Y - anotarisira kuti mukomana aberekwe .
Ndezvipi zviri nani kubata mukomana, uye musikana aripi?
Pamusana pekutarisira kweupenyu huri pasi hwe-Y-soro spermatozoa, zvakanakisisa kuita rudo rwemangwana remurume zvakanyatsoitika pamazuva ekukwezva. Yaiva panguva iyi iyo Y-spermatozoa
Nokuda kwekuberekwa kwemusikana, pane kudaro, munhu anofanira kuedza kutora pamuviri apo chiyero che spermatozoa mumumvuri chinonyanya mumhumhu. Kuwedzera mikana yekuberekwa kwemusikana, edzai nzira inotevera. Tanga kuronga mwana kwemazuva 3-4 kusati kwasvika kubuda kweivulation, munyaya iyi, nenguva yekubuda kwezai rakakura, chete chete X-spermatozids ichapona, iyo ichabatanidza nayo.
