Vabereki vazhinji vane chishuwo chikuru uye hope dzekuwedzera mwanakomana kana mwanasikana kumhuri yavo. Dzimwe nguva zvinogona kunge zviri zvekuzadzisa mhuri. Dzimwe nguva, zvinogona kunge zvichikonzerwa netsika dzemhuri. Zvakare, kune zvimwe zvirwere zvemajini zvinogarwa nhaka nemunhurume kana kuti murume. Kuti vadzivirire mwana kubva kuzvirwere zvakadaro, vamwe vabereki vanofunga zvakananga nezvehunhu hwemwana. Chero chikonzero chipi zvacho, vanhu vazhinji vane mubvunzo wekuti, "Pane nzira chaiyo yekusarudza hunhu hwemwana watichava naye here?" Ngatitaurei nezvazvo nhasi.
Sainzi yezvekurapa inoti chii chaizvo nezveizvi?
Zvichitaurwa zviri nyore, kana ukaita pamuviri kuburikidza nekuita zvepabonde kwakajairika, mikana yekubereka mukomana kana musikana ndeye 50/50. Izvi zvinoreva mikana miviri yakaenzana . Asi vanhu vazhinji vari kutsvaga kana vachigona kuwedzera mukana uyu zvishoma kuti vabatsirwe.
Asi heino kunetseka kuri kutaurwa navanachiremba nenyanzvi dzezvehutano. Kureva kuti, vamwe vabereki vane tariro huru munzira idzi uye vanoodzwa mwoyo zvikuru kana vakasazadzisa zvavaitarisira. Fungidzira, ko kana ukatevera imwe nzira uchitarisira mwanakomana, asi wozopedzisira wava nemusikana? Kana kuti ko kana uine mwanakomana sezvawaitarisira, asi asina hunhu hwawaifungidzira? Muzviitiko zvakadaro, kuora mwoyo ikoko kunogona kukanganisa ramangwana remwana uye hutano hwepfungwa.
Saka chinhu chakakosha kurangarira ndechekuti hapana imwe yenzira idzi inogona kuvimbiswa kuti inoshanda zvizere. Dzimwe nzira dzakakurumbira dzinogona kunge dzakabva pangano.
Kutaura zvazviri, kune mimwe mitambo yaiitwa navanasekuru vedu. Vanachiremba vanovaseka vachiti, "Kana nzira idzodzo dzikasakuvadza amai nemwana, hazvina kuipa kuedza."
Nzira dzechisikigo dzinoshanda zvechokwadi here?
Nzira yechisikigo inozivikanwa zvikuru yekusarudza bonde remwana ndiyo nzira yeShettles . Yakatangwa makumi emakore apfuura naDr. Landrum B. Shettles. Nzira iyi yakavakirwa pazuva reovulation uye nzvimbo yepabonde.
Ndeipi nzira yeShettles?
Sekureva kwaDr. Shettles, mbeu yemurume inobereka mwana wechirumeMbeu yemurume (ine chromosome yeY) idiki, inokurumidza, uye inorarama kwenguva pfupi. Zvisinei, mbeu inobereka mwana wechikadzi (ine chromosome yeX) yakakura, inononoka, uye inogona kurarama kwenguva yakareba.
Saka zvichienderana nedzidziso iyi, anotaura chimwe chinhu chakadai.
| Kana uchida | Nzira yekutevera (zvichienderana nenzira yeShettles) |
|---|---|
| Mukomana | Bonde rinofanira kunge riri pedyo neovulation yemukadzi sezvinobvira . Izvi zvinobvumira mbeu yeY inokurumidza kusvika zai isati yasvika mbeu yeX. Uyewo, nzvimbo dzinoisa mbeu yeY pedyo nemuromo wechibereko (semuenzaniso, kupinda kumashure) ndidzo dzakanakisa. |
| Musikana | Unofanira kuita bonde mazuva maviri kusvika mana ovulation isati yabuda . Kana zai rabuda, mbeu yeY inorarama kwenguva pfupi inenge yafa, zvichisiya mbeu yeX inorarama kwenguva refu uye yakasimba. Zvinonzi nzvimbo yeumishinari, murume ari pamusoro, ndiyo nzvimbo yakanakisisa. |
Kunyange hazvo nzira yeShettles Method ichinzi yakabudirira ne75%, vamwe vanachiremba vezvekubereka vana nevemadzimai vanobvunza kuti nzira idzi dzechisikigo dzinobudirira sei. Vanoti mikana yekubereka mwana nedzimwe nzira idzi haisi kupfuura 50/50.
Zvisinei, pane maonero akasiyana zvachose neizvi. Dr. J. Martin Young, chiremba, anoti nzira yeShettles inobudirira chaizvo nechikamu chidiki che39%. Anotaura maonero anopesana nemaonero aShettles.
- Kana uchida musikana , ita bonde pedyo nekubuda kwembeu .
- Kana uchida mukomana , ita bonde mazuva mashoma ovulation isati yasvika .
Unoona, hapana kubvumirana pakati penyanzvi dzakasiyana-siyana kunyangwe nezvenzira idzi dzechisikigo.
Ndedzipi nzira dzeHigh-Tech?
Kunewo nzira dzakawanda dzemazuva ano dzinoti dzinopa mhedzisiro inoshanda kupfuura nzira dzechisikigo. Idzi dzinodhura uye hadziwanikwe kwese kwese.
Nzira yeMicroSort
Iyi ndiyo nzira inogamuchirwa zvikuru uye inoshanda pakusarudza bonde. Inosanganisira kushandisa dhayi yakakosha, chiedza chelaser, nemuchina unonzi flow cytometer kuparadzanisa mbeu dzeX- neY. Mbeu inodiwa inobva yaiswa muchibereko chemukadzi nenzira yekugadzira. Nzira iyi inowanzoitwa neIn Vitro Fertilization ( IVF ) .
Zvinoenderana nemishumo, nzira iyi ine mwero wekubudirira we91% kune avo vanotarisira vasikana uye mwero wekubudirira we73% kune avo vanotarisira vakomana .
Nzira Dzinokakavadzana
Kune dzimwe nzira mbiri, asi kune nyaya huru dzetsika nedzemutemo dzakapoteredza kushandiswa kwadzo.
1. Kuongororwa Kwemajini Pamberi Pekuiswa Muchibereko (PGD): Izvi zvinosanganisira kuyedza mazai anokura kunze kwechibereko chaamai kuburikidza neIVF asati aiswa muchibereko, uye kusarudza mazai ane bonde rinodiwa kuti aiswe.
2. Chorionic Villus Sampling (CVS): Nzira iyi inogona kuona bonde remwana ari mudumbu nekuongorora machromosome emwana ari mudumbu pakutanga kwekuzvitakura.
Chinhu chinonyanya kukosha: Zvese PGD neCVS zvakagadzirirwa kuyedza zvirwere zvakakomba zvemajini. Kuzvishandisa kusarudza bonde remwana ane hutano kunoonekwa sekusina hunhu munyika dzakawanda. Kwave nemishumo yekuti vamwe vanhu vanobvisa pamuviri pavanoona kuti vakabata pamuviri wemwana asiri wepabonde kuburikidza nenzira idzi. Saka, masangano ekurapa haakurudzire kushandisa nzira idzi nechinangwa chekudzikamisa mhuri.
Mharidzo Yekuenda Nayo Kumba
- Kazhinji, une mukana we50/50 wekuva nemwanakomana kana mwanasikana.
- Kunyangwe paine nzira dzechisikigo, dzakadai seShettles method, kubudirira kwadzo hakuna kusimbiswa nesainzi 100%, uye kune mafungiro akasiyana kunyangwe pakati penyanzvi.
- Kunyange zvazvo matekiniki emazuva ano akadai seMicroSort achibudirira zvikuru, anodhura zvikuru, akaoma, uye haawanikwe nyore munyika medu.
- Nzira dzakadai sePGD neCVS dzakagadzirwa zvakanyanya kuona zvirwere zvemajini. Kudzishandisa pakusarudza bonde kunokakavadzana zvikuru.
- Usati waedza chero nzira, chengeta zvaunotarisira zviri zvechokwadi . Zvakakosha kudzivirira kushushikana kunouya nekuora mwoyo.
- Yeuka, zvinopfuura kuva murume kana mukadzi kwemwanaKuva nemwana ane hutano ndiko kunokosha.
- Usati waedza chero nzira ipi zvayo panyaya iyi, iva nechokwadi chekutaura nachiremba wako uye uwane mazano akakodzera.
