Ngendlela elula i i-cryopreservation kungenzeka ukuthi iqandise ama-oocyte, izicubu, imibungu noma isidoda, kwabesifazane nabesilisa. Ngokuvamile, okwenziwa kaningi ukubanda amaqanda, kepha kukhona namanye amathuba. Namuhla sizokhuluma ngokukhethekile ngokubandiswa kombungu.
Le ndlela iya ngokuya ivama, bobabili ngabesifazane abafuna ukubambezela ukuba kwabo omama, yize bephilile, nalabo abahlushwa umdlavuza noma ezinye izinkinga. Njalo eminyakeni emibili umtholampilo, noma ibhange lombungu lapho kugcinwa khona elakho, lizokubuza ukuthi uyafuna yini ukuqhubeka nokuligcina. I- izindleko zensizakalo yesondlo, ngaphezulu noma ngaphansi, phakathi kwama-euro angama-300 nama-600 ngonyaka.
Kusebenza kanjani ukubanda kwe-umbungu noma ukugcinwa kwe-cryopreservation?
Ngemuva kwabesifazane asebenze imijikelezo ye- in vitro fertilization, kunemibungu embalwa esezingeni elifanele engeke isetshenziswe. Ukuyigcina, kudingeka ukuthi kugcinwe imibungu emincane, iqandiswe imibungu elondolozelwa imizamo ezayo. Imibungu efriziwe igcinwa emathangini ane-nitrogen engamanzi ku -196 degrees Celsius.
Ukubanda kombungu kumayelana inqubo engaguquli noma eguqule ikhwalithi yemibungu. Kwenziwa nge-vitrification, inqubo engeyona enobudlova kakhulu, uma uyiqhathanisa naleyo yakudala eqandayo ehamba kancane, evumela ukuthi kube nokuphila okuphezulu kanye namazinga okukhulelwa. Noma kunjalo, ngokujwayelekile, ukuqandisa nokuncibilika kuyizinqubo ezingaba nolaka zemibungu, noma kungenjalo njengolaka njengoba kwakunjalo ngaphambili.
Nge-cryopreservation inciphisa ubungozi bokukhulelwa okuningi. Njengoba kunethuba lokungadlulisi yonke imibungu ngasikhathi sinye, kepha ingagcinwa futhi ibe namathuba amaningana. Lokhu futhi kugwema ukubeka owesifazane ekwelashweni okusha okugqugquzela ama-ovari kanye nokubhoboza okusha.
Kunconyelwa obani le ndlela?
Ukwedluliswa kwemibungu kuyindlela enconyelwe labo besifazane asebethole imishanguzo yokusizakala eyinkimbinkimbi kakhulu futhi enemibungu engenakudluliswa isha sha. I- imibandela okumele ihlangabezane nale mibungu ifuna futhi ihlukile kuleyo ehlangabezana naleyo mibungu efakwe ku-in vitro fertilization.
Esinye sezizathu zokuthi kungani ayikwazi ukudluliswa, isibonelo ukuthi yeqa ngenani. Emthethweni waseSpain kuvunyelwe ukudlulisela imibungu efinyelela kuma-3. Kuyindlela futhi etusekayo kulawo macala, lapho kungakhathalekile inani lemibungu etholakalayo, kunqunywa ukuthi kungadluliselwa okusha esibelethweni sikamama, kungaba ngokuzikhethela kowesifazane noma ngenxa yezizathu zezokwelapha.
Esinye isibonakaliso sokudilizwa kombungu kungaba ngamacala lapho elinye lamalungu alo mbhangqwana lihlaselwa yisifo okuthi, kamuva, limvimbe ekutholeni ama-gametes. Lokhu kunjalo, ngokwesibonelo, kwabesifazane okufanele bathole ukwelashwa ngamakhemikhali.
Izinkinga zezomthetho mayelana nokubanda kombungu eSpain
Umthetho 14/2006 kaMeyi 26, ngezindlela ezisizwayo zokukhiqiza kabusha abantu, kusungula isibopho sokugcina kabusha yonke imibungu esebenzayo esuselwe kumjikelezo wokusiza wokukhiqiza.
ESpain kunezindawo ezi-4 ezingaba khona:
- Su ukusetshenziswa ngumfazi uqobo noma owakwakhe. ESpain umkhawulo wokuthi owesifazane awasebenzise iminyaka engama-50.
- Ukunikela ngenhloso yokuzala. Zinganikelwa kwabanye abantu, mahhala, ngokungaziwa, okusemthethweni nokuyimfihlo. Le nketho ayisetshenziswa kabanzi.
- Umnikelo wocwaningo. Kulokhu, imibungu kuphela engakakhi i-in vitro ngemuva kwezinsuku eziyi-14 ngemuva kokukhulelwa kwe-oocyte okunganikelwa ocwaningweni.
- Ukuphela kokongiwa, ngaphandle kokunye ukusetshenziswa. Kusebenza kuphela uma isikhathi sokulondolozwa esiphezulu esisungulwe ngumthetho sesiphelile.
Ngesikhathi sokuqala ukwelashwa kwe-vitro fertilization, kuzodingeka ukwenze nquma futhi usayine lapho uya khona ngemibungu efriziwe engadluliswanga. Kuwo wonke ama-cryopreservation ungashintsha lesi sinqumo.
