Abesifazane abaningi bafuna ukukhulelwa indodakazi, ikakhulukazi uma sebevele benabantwana. Ngaphambilini, amantombazane asebenzisa izibonakaliso ezahlukene nezinkolelo-ze ukuze kwandiswe amathuba okukhulelwa, kepha omama banamuhla banesithakazelo kolwazi lwezokwelapha. Kunezindlela eziningana zesayensi ezizwakalayo zokufeza umsebenzi.
Izindlela zokukhulelwa intombazane
Abazali abasebasha benza izinketho zendabuko kanye nezimpumalanga zokulawulwa kwe-in vitro fertilization. Ukukhulelwa intombazane lezi zindlela ezilandelayo zisetshenziswa:
- Ukubala izinsuku ngaphambi kokuqala kwe- ovulation ;
- ukuzimisela kwesikhathi sokuvuselelwa kwegazi;
- Amatafula aseJapane;
- Ikhalenda ye-Chinese ;
- izindlela zomzimba;
- ukulungiswa kwamandla.
Ikusasa likababa nomama kubalulekile ukuqaphela ukuthi amathuba okukhulelwa intombazane ngisho nalapho esebenzisa yonke into ekhonjwe ngenhla yanda kancane. Inqubo yokukhulelwa ihambisana nezinqubo eziyinkimbinkimbi zomzimba namakhemikhali, okulukhuni ukuwuthonya ngaphandle. Lezi zindlela kuphela ukunyuka okuncane emathubeni okukhulelwa umntwana osalinde isikhathi eside, hhayi isiqinisekiso sokuphumelela.
Indlela yokukhulelwa intombazane nge-ovulation?
Ubulili bomntwana buxhomeke kwiqoqo lezinhlelo ze-nucleoprotein. Emangqamuzaneni okuzala, kunamadoda amabili nabesifazane ababili. Iqanda liqukethe i-X-chromosomes, kanti i-spermatozoa ingaba ngohlobo lwe-X no-Y. Indlela kuphela yokukhulelwa intombazane ukuhlinzeka nge-gamete yesifazane ngokukhulelwa ngesilwane sesilisa ngesisindo se-X. Ngesethi ye-chromosome XY, umfana uzozalwa.
Ososayensi bathole ukuthi i-spermatozoons "yesilisa" iyona ehamba phambili kakhulu futhi iyashesha, kodwa ihlala isikhathi esingaphezu kwezinsuku ezimbili futhi ibulawa kalula yi-medium acidic. "I-Zhivchiki" ne-X-chromosome iyashesha, kodwa iqinile. Ziyamelana nezimo ezimbi futhi ziyakwazi ukuhlala izinsuku ezingu-3, zilinde iqanda. Ngesisekelo salolu datha, kulula ukubala ukuthi yiziphi izinsuku intombazane engakhulelwa ngayo.
Uma sicabangela isikhathi somsebenzi we "spermatozoa" wesifazane, kunconywa ukuba wenze uthando mayelana namahora angu-72 ngaphambi kokuvuthwa. Ngemva kwalokhu, kuzomele ulinde ngocansi izinsuku ezingu-3-4. Ngokweqile, ama-gametes anama-Y-chromosomes afa esikhathini esibekiwe, kanti i-X. izohlala. Ngenxa yalokho, i-nucleoprotein kit iyoba yi-XX futhi emva kwezinyanga ezingu-9 umndeni uyobe uhlotshaniswa nomntwana othandekayo.
Indlela yokukhulelwa intombazane yokuvuselelwa kwegazi?
Kukhona inkolelo yokuthi ukwakhiwa kwamanzi okuphila komuntu wesilisa nowesifazane kuyashintsha ngokuphelele ngezikhathi ezahlukene-iminyaka engu-4 no-3. Kule mibono, le ndlela isekelwe endleleni yokukhulelwa intombazane ngegazi:
- Isikhathi sobaba esizayo kufanele sihlukaniswe sibe ngu-4, futhi omama bahlukaniswe ngo-3, kodwa kuphela okumele kubhekwe. Isibonelo, indoda ineminyaka engu-35 ubudala, kanti owesifazane uneminyaka engu-28. Imiphumela iyoba ngu-8 no-9.
- Ukwandisa izindinganiso ezitholiwe ngo-4 no-3. Esikhathini esidlulisiwe, izimpendulo zingu-32 no-27.
- Susa lezi zibalo kusukela kuminyaka yamanje. Lapha - 35-32 no-28-27.
- Qhathanisa imiphumela. Kulesi simo, 4 no-1.
- Ubulili bomntwana buzofana nalokho komzali ogama lakhe lavuselelwa kamuva. Kulesi sibonelo, uketshezi oluthe xaxa oluthi "olusha" oluphilayo kumama.
Indlela yokukhulelwa intombazane - itafula
Kukhona indlela yaseJapane yasendulo yokuthonya ukukhulelwa kweqanda nokukhishwa kwe-chromosomes. Kuhilela ukubala ukuthi yiziphi izinsuku zokukhulelwa intombazane esebenzisa itafula elikhethekile kanye neshadi elixhunywe kuyo. Okokuqala, kubalulekile ukuba "uhlanganise" izinyanga zokuzalwa kwezinsuku zikayise nomama. Kulo gridi elingezansi, udinga ukuthola inombolo (1-12) emkhatsini wabo.
Inombolo etholakele kufanele ikhunjulwe futhi iphawulwe ngesigrafu esethuliwe. Uzosiza ukuthola indlela yokukhulelwa intombazane futhi ukhombise inyanga ehle kakhulu. Ngokwesibonelo, umama wazalwa ngo-Ephreli, futhi ubaba wazalwa ngoFebhuwari. Inani labo "elihlanganyelwe" labangu-8. Ngokusekelwe ezinkomba zesilinganiso esiphakathi kwesimiso, ithuba elikhulu lokukhulelwa kwengane lizoba ngo-Ephreli noDisemba (kancane kancane).
Indlela yokukhulelwa intombazane - ikhalenda
AmaShayina asendulo ayekholelwa ukuthi ubulili bezinhlanzi kuthinteka kuphela ngumama wesikhathi esizayo. Bakha ikhalenda ekhethekile ebonisa ukuthi kungcono ukukhulelwa intombazane. Owesifazane udinga ukuthola inani leminyaka egcwele emgqeni ophezulu bese ubhala izinhlamvu "D". Ezinyangeni ezihambisana namaseli akhethiwe, imizamo esebenzayo yokukhulelwa iyanconywa. Lena indlela elula, kodwa engathembeki, indlela yokukhulelwa intombazane. Ngokwezibalo zamamama, akayiqiniso ngokuphelele futhi ufanelekile kuphela ukuzijabulisa.
Isiphi isikhundla sokukhulelwa intombazane?
Ngokusekelwe ebubini kanye nesivinini se-X-spermatozoa, kudingeka badedele "abancintisana" ekukhuliseni i-ovum. Ukuqinisekisa ukuthi i-gametes ene-Y-chromosomes ayinayo isikhathi sokufinyelela ama-gametes kuqala, kuyadingeka ukukhetha izikhundla ngaphandle kokungena okujulile. Indlela yokukhulelwa kahle intombazane - indawo ehle embhedeni:
- "Izithunywa zevangeli";
- "Umgibeli";
- "I-spoonful."
Yini okufanele uyidle ukuze ube nentombazane?
Kunombono mayelana nomthelela wesidlo sowesifazane ngokulala komntwana wakhe. Ngokwale mbono, umama wesikhathi esizayo udinga okungenani ngesonto nengxenye ngaphambi kokuzama ukukhulelwa ukulungisa ukudla kwakhe. Yini okufanele udle ukuze ube nentombazane:
- inkomo;
- i-veal;
- iwundlu;
- i-cottage shizi;
- ubisi;
- ushizi;
- ukhilimu omuncu;
- imana, izitshalo zelayisi;
- izaqathe;
- amabhontshisi;
- ubhontshisi;
- ukhukhamba;
- isitshalo seqanda;
- i-strawberry;
- ama-apula;
- ulamula;
- amapheya;
- amakhabe;
- i-raspberries;
- ama-peaches;
- amaphayinaphu;
- i-mango;
- i-cocoa;
- itiye.
Ukuhambisana nalezi zincomo zokudla, njengoba zikhulelwe ukuba zikhulelwe intombazane, zenze iqhaza ekwakheni imvelo enhle ngamaseli ocansi nge-X-chromosomes. Umama wesikhathi esizayo akudingeki ukuba alandele ngokuqinile, ehluleke kwezinye ukudla nokuphuza. Lezi nje nje amathiphu angasiza ngokungaqondile ukufeza umgomo.
