Iqanda elikhulelwe lenza indlela enzima yokungena esibelethweni - indawo lapho izokhula khona phakathi nokukhulelwa. Esibelethweni, iqanda lingena esiteji se-blastocyst. I-Blastocyst ibhola eligcwele uketshezi. Ingqimba yangaphandle ye-blastocyst izothela ekugcineni ibe yi-placenta, futhi amangqamuzana angaphakathi abe yi-embryo. Manje kufanele athole inqubo yokufakelwa, okusho ukunamathiswa kombungu kumbele. Kungemva kokuqedwa kokufakelwa kwesimo sokukhulelwa kubhekwa ukuthi sekufikile.
Imibandela yokufakelwa kwe-embryo
Uma esiswini esiswini, umbungu ungena mahhala izinsuku eziningana, bese inqubo yokufakelwa iqala ngokushesha. Iwindi okuthiwa i-implantation window ifika ezinsukwini ezingu-6-8 emva kokuvuthwa. Ukufakelwa kombungu emgqeni wesibeletho kwenzeka ngosuku lweshumi nanhlanu emva kokukhulelwa. Umbungu kufanele uhlanganise ngokugcwele nomzimba womama. Ngokwesilinganiso, umbungu udinga izinsuku ezingaba ngu-13 ukuze ugxilwe ngokuqinile esibelethweni. Ngesikhathi lapho umbungu unamathele esibelethweni, owesifazane angase abe nokuphuma okuncane kwamanzi. Lokhu kungenxa yokunamathiselwe kombungu kuya kwesibeletho. Phakathi nalesi sikhathi sonke kunamathuba aphezulu okukhulelwa kwesisu.
Ukuze umklamo uphumelele emzimbeni, abesifazane kufanele bahambisane nefasitela lokufakelwa, ukulungele kwesibeletho ukwamukela umbungu, nokuba khona kwe-ovum esifinyelele esiteji se-blastocyst. Ngemva kokuba i-blastocyst ifakwe, ukwakheka kombungu ngokuqondile kuxhomeke emzimbeni womama. Manje babe nobuhlobo obuseduze kakhulu nomunye nomunye.
Kungani kungenakho ukufakelwa kwe-embryo?
Njengoba kuyaziwa, cishe ama-40% we-blastocysts angena esibelethweni ngempumelelo awafakiwe. Esinye sezizathu zokuthi umbungu unqatshelwe ukuhlukumeza ku-endometrium - okuthiwa i-uterine membrane. Le membrane angeke ibe neqhamuka ngokwanele ye-blastocyst. Noma kunamaphutha. Ngokuvamile, ukukhipha isisu kuyimbangela yokungavamile ku-endometrium. Ngenxa yalokho okungavamile, ukukhubazeka okukwenzekayo kwenzeka. Kulesi simo, abesifazane abaningi abaqageli ngokukhulelwa, ngoba iqanda elikhukhulayo lihamba ngezinyanga ezizayo.
Ukuhlukaniswa kwemibungu
Ukuhlukaniswa kwemibungu kusetshenziswe imitholampilo eyenziwa ukukhulelwa kwe-IVF. Umtholampilo ngamunye unesigaba sakhe siqu. Noma kunjalo, okuvame kakhulu kulawa yi-alphanumeric classification.
Ukuhlukaniswa ngokuyinhloko kuhlola ikhwalithi nokubukeka kombungu. Isici esiyinhloko ekuhlukanisweni kwemibungu ngezinsuku ezimbili nezinsuku ezintathu zokuthuthukiswa yinombolo yamaseli, kanye nekhwalithi yabo.
I-embryo efanelekayo kufanele ibe nenombolo elandelayo yamaseli:
- izinsuku ezingu-2 - kusuka kumaseli amabili kuya kwangu-6;
- izinsuku ezingu-3 - kusuka kumaseli angu-4 kuya kwangu-10;
- izinsuku ezingu-4 - amangqamuzana angaphezu kuka-8.
Amanani okuhlukaniswa abonisa ubungako blastocyst, kanye nesiteji sokwandiswa. Kunezinyathelo ezingu-1 kuya kwezi-6. Kweminye imitholampilo, ngibuye ngibonise inani lamaseli ngezinombolo.
Incwadi yokuqala esetshenziselwa ukuhlukaniswa kubonisa izinga lomzimba wangaphakathi weseli, lapho i-embryo iqala khona. Kuvunyelwe ukuhlukanisa izigaba ezilandelayo - A, B, C, D, okuyi-A eyona ehle kakhulu.
Incwadi yesibili ibonisa ikhwalithi ye-trophoblast - lokhu kungqimba lwangaphandle lwe-blastocyst. Yilolu ungqimba
Ukusebenzisa ukuhlukaniswa kwemibungu, izikhungo zokwehlukaniswa kwamakhemikhali ezithintekayo zithatha ngokunembile iseli elikwazi ukuzihlanganisa ne-epithelium lesibeletho ngendlela engcono kakhulu. Kuvela kuye ukuthi umbungu ophilile futhi ogcwele uzoqhubeka. Ngemuva kokuba inqubo yokufakelwa isiphelile, inqubo esebenzayo yokukhula kombungu ngaphakathi komama iqala.
