Okokuqala nje, izinsuku ezivundile yizinsuku lapho ukuvundiswa kungenzeka ngemva kocansi.
Ngokuvamile siyalazi iqiniso lokuthi i-ovum iyafa ngemva kwamahora ambalwa, nokuthi isidoda singaphila izinsuku ezingu-2 noma ngaphezulu. Ucwaningo mayelana nalokhu lubonise ukuthi kwabesifazane abanempilo izinsuku ezivundile kakade seziyizinsuku ezingu-5 ngaphambi kwe-ovulation nangosuku lwe-ovulation, kodwa amathuba okukhulelwa akhona futhi ezinsukwini ezi-2 ngemva kokuvuthwa kweqanda kanye nezinsuku ezingu-6-8 ngaphambi kwalokho, kuyavunywa ukuthi ingaphansi kuka-5. %, kodwa hlala ukhumbula leli qiniso. Amathuba aphezulu okufakelwa kwe-zygote, kuye ngeminyaka yowesifazane, kwenzeka ezinsukwini ezi-2-3 ngaphambi kokuvuthwa kweqanda futhi afinyelela ku-50%.
Khona-ke umbuzo owodwa ufika engqondweni, indlela yokubikezela lezi zinsuku? Kuyafaneleka ukwazi impendulo yazo, kokubili lapho sizama ukukhulelwa nalapho sifuna ukugwema ukukhulelwa.
Ngendlela engokwemvelo, singakwazi ukubala lapho izinsuku zethu ezivundile ziphuma ngezindlela ezimbalwa ezifakazelwe neziqinisekisiwe.
Okokuqala - ukuhlolwa kwamafinyila omlomo wesibeletho – indlela esivumela ukuthi sihlole ukuthi izinsuku ezivundile zaqala futhi zaphela nini. I-mucus ngaphambi nangesikhathi sokuvuthwa kwayo iyanamathela futhi iyanwebeka, kuyilapho ngemva kokuvuthwa komile futhi iwugqinsi. Ukuphumelela kokusebenzisa le ndlela kusuka ku-78% kuya ku-97% uma silandela zonke izincomo zayo.
Enye indlela yile uphawu-ezishisayo Kuhilela ukubhekwa kwezinkomba ezingaphezu kwesisodwa zokuzala kowesifazane. Izinga lokushisa kanye namafinyila omlomo wesibeletho kuvame ukukalwa. Kunamasu amaningana kule ndlela. Uma isetshenziswe ngendlela efanele, inikeza ukusebenza kahle okuqhathaniswa namadivaysi e-intrauterine, okungukuthi 99,4% -99,8%.
Kukhona futhi indlela yokuncelisa yokungazali kwangemva kokubeletha. Ifinyelela ku-99% ukusebenza kahle. Nokho, izimo ezithile kufanele kuhlangatshezwane nazo:
- ingane akufanele ibe mdala kunezinyanga eziyisi-6
- ukuya esikhathini akufanele kwenzeke
- futhi ingane kufanele inceliswe ibele lodwa, uma ifunwa, okungenani njalo ngamahora ama-4 phakathi nosuku namahora ayisi-6 ebusuku.
Nokho, ubude balesi sikhathi sokungazali abubikezeleki ngoba umjikelezo omusha uqala ngokuphuma kweqanda, hhayi ukopha.
Indlela yokushisa kunalokho, kuhlanganisa ukwenza izilinganiso ezivamile, zansuku zonke zokushisa komzimba wesifazane. Isilinganiso kufanele sithathwe ekuseni ngaphambi kokuvuka, njalo ngesikhathi esifanayo. Ngale ndlela, igrafu idalwe ebonisa ukuthi ngemva kokuya esikhathini izinga lokushisa lomzimba liphansi, khona-ke kukhona ukwanda okusheshayo futhi izinga lokushisa lihlala liphakeme cishe izinsuku ezingu-3. Khona-ke singakwazi ukunquma ukuthi izinsuku zethu ezivundile zenzeka nini, ngoba izinsuku ezingu-6 ngaphambi kokushisa okuphezulu kanye nezinsuku ezi-3 ngemva kwalokho. Ezinye izinsuku ziyinyumba.
Njengamanje, indlela yokushisa ingenziwa ngokuphumelelayo kusetshenziswa ikhompyutha yomjikelezo, okuthi, uma isetshenziswe kahle, iqhathaniswe nokuvimbela inzalo kwama-hormone. Ngokuqinisekile bathuthukisa induduzo yokusebenzisa indlela yokushisa, futhi baphinde bathuthukise ukulinganisa kwayo.
