Isigaba esibalulekile esilandelayo ekuthuthukiseni umbungu emva kokukhulelwa kwe-ovum ne-sperm kuyinto ukufakwa. Umntwana unamathele emgodini we-uterine futhi uqala ukukhula nokuthuthukisa. Zingaki izinsuku ezidlula phakathi kokukhulelwa nokufakelwa futhi kungenzeka ukuthi uzizwe? Isikhathi eside ukufakelwa kwe-embryo kuphele isikhathi esingakanani?
Ngabe i-embryo ifaka nini kwisibeletho?
Masinyane emva kokukhulelwa, iqanda liqala ukuhamba ngezigubhu ze-uterine ukuya esibelethweni. Kule ndlela, kungathatha izinsuku ezingu-7-12, isilinganiso sezingu-10. Isikhathi sokuhamba kwe-ovule phezu kwamatayipi wezintambo kuncike ezintweni eziningi, kufaka phakathi ubude bawo. Nokho, ukuze kuthuthukiswe iseli, ukudla okudingekayo kuyadingeka, ngakho-ke, lapho amasheya ephuma, ifakwe ku-epithelium yesibeletho. Izigulane ezibeletha zivame ukwenza lula le nqubo, kugcizelela izinto ezikhethekile ezenza ukunamathiselwe kombungu.
Isikhathi sokufakelwa kwe-embryo singaba yizinsuku ezimbili, njengoba sigxila epithelium yesisu hhayi ngokushesha, kodwa kancane kancane, engxenyeni yokuqala, bese kuthi ngokuphelele, emva kwezinsuku ezimbalwa zihlanganiswe ngokuphelele nge-epithelium futhi iqala ukuthuthukisa. Kuphela emva kwalokhu, inqubo yokufakelwa inqatshelwe ukuthi igcwaliswe ngokugcwele. I-embryo ehlanganisiwe ivuselela ukukhululwa kwama-hormone okukhulelwa, okubangela ukuthuthukiswa kwayo okuqhubekayo.
Usuku lwe-embryo implantation, owesifazane olindele ukukhulelwa, angakwazi ukubona izinhlungu ezincane zokudonsa esiswini esingaphansi nokubonakala kwesilinganiso esincane sokukhishwa kwesibhakabhaka. Abanye besifazane badidanisa lokhu ngokuqala komjikelezo olandelayo, njengoba ukufakelwa kombungu kuhambelana kahle nokuqala okulindelekile komjikelezo omusha. Noma kunjalo, izimpawu ezikhulayo ze-toxicosis nokuntuleka
Khuluma ngokuqondile - emva kwezinsuku ezingakanani umbungu unamathele - akunakwenzeka, ngoba awukwazi ukucacisa ngokunembile isikhathi sokukhulelwa. Emva kokuvuthwa nokulala ngokocansi, kungenziwa kokubili emahoreni wokuqala, futhi ezinsukwini ezimbalwa. Kodwa-ke, njengomthetho, kuthatha amasonto amabili ukukhulelwa nokufakelwa. Kuphela kwabesifazane abaye babhekana nenqubo ye-IVF ukuze bazi kahle ukuthi usuku lokufakelwa kombungu lwaluphi usuku, ngoba ama-embryo fusion esimweni sabo ayaziwa ngamahora ambalwa.
