Ithemba elitsha lokuchuma: Konke malunga nendlela yonyango lwe-ICSI (Intracytoplasmic Sperm Injection)

Ukwenza iphupha lokuba nomntwana libe yinyani ngamanye amaxesha kunokuba ngumceli mngeni omkhulu, akunjalo? Le yingongoma ebucayi kakhulu, ingakumbi kwizibini ezijongene nengxaki yokungabi nabantwana. Ngoko ke namhlanje siza kuthetha ngendlela ekhethekileyo yonyango kwizonyango zanamhlanje enokunceda kwiingxaki ezinjalo. Le yi-ICSI, okanye i-Intracytoplasmic Sperm Injection . Nangona eli gama liyinkimbinkimbi kancinci, masiliqonde ngokulula.

Yintoni i-ICSI? Yintoni umahluko phakathi kwe-IVF kunye ne-ICSI?

I-ICSI yindlela ekhethekileyo yonyango esetyenziselwa ukungazali. Enyanisweni, yinxalenye ye- In Vitro Fertilization (IVF) .

Khawucinge nje, kwinkqubo eqhelekileyo ye-IVF, iqanda lomfazi lithathwa kwilebhu lize lijikelezwe ngamawaka amadlozi endoda. Emva koko, elinye lala madlozi lihlaba iqanda lodwa lize lilinde ukuba kuqhamke. Kufana nokuphumelela ugqatso. Kodwa ngamanye amaxesha, akukho nelinye idlozi elinokungena ngaphakathi kweqanda. Emva koko ukuqhamkeka akwenzeki.

Iqanda elivundisiweyo libizwa ngokuba yi- embryo . Eli qanda lifakwa kwisibeleko sikamama. Ukuba i-embryo inamathela eludongeni lwesibeleko, ukukhulelwa kuyaqala. Le ndlela ibizwa ngokuba yi-Assisted Reproductive Technology (ART) .

Ngubani onokuthi afune unyango lwe-ICSI?

I-ICSI iluncedo kakhulu kumadoda aneengxaki zokungazali kwamadoda . Ugqirha wakho angacebisa olu nyango ukuba indoda inayo nayiphi na kwezi meko zilandelayo:

Ukongeza, i-ICSI inokuba yimfuneko ngezinye izizathu:

• Ukuba unyango lwe-IVF oluqhelekileyo lwangaphambili luye lwaphumelela kwaye akukho mbungu oye wavela.
• Ukuba umfazi okhupha amaqanda uneminyaka engaphezu kwama-35 ubudala.
• Ukuba amaqanda okanye isidoda ebesikhenkceziwe ngaphambili (esigciniweyo) sisetyenziselwa unyango.

Inkqubo ye-ICSI yenzeka njani?

Le yinkqubo eyenzeka ngamanyathelo aliqela. Masijonge la manyathelo ngokulandelelana kwawo.

1. Ukuqokelela amaqanda kunye nesidoda

Ukufunyanwa kwamaqanda:

• Ukuqaliswa kokuvuthwa: Okokuqala, umfazi onika amaqanda unikwa inaliti yehomoni imihla ngemihla malunga neentsuku ezisi-8 ukuya kwezili-14. Oku kuvuselela ama-ovari kwaye kubangele ukuba akhule amaqanda amaninzi ngaxeshanye.
• Ukufunyanwa kwamaqanda: Emva koko, kufakwa i -anesthetic elula, kufakwa inaliti encinci kakhulu nge-vaginal, kwaye amaqanda avuthiweyo asuswa ngononophelo kwii-ovari phantsi kwesikhokelo se -ultrasound scan ye-transvaginal . Oku akubuhlungu.

Ukuqokelelwa kwesidoda:

• Imbewu idla ngokuqokelelwa ngosuku olufanayo naxa amaqanda eqokelelwa.
• Indoda enikelayo mayiyeke ukwabelana ngesondo okanye ukuphulula amalungu esini kangangeentsuku ezimbini ukuya kwezintathu.
• Emva koko, kufuneka uqokelele isidoda ngokuphulula amalungu esini kwisitya esikhethekileyo esibonelelwe ekliniki. Esi sampuli kufuneka sithunyelwe kwilabhoratri kwisithuba seyure.
• Kwabanye abantu (umz., abo bangakhupheli i-ejaculateKwimeko ye- azoospermia , ezinye iindlela ezikhethekileyo zokufumana isidoda (umz. ukukhutshwa kwesidoda esincinci se-testicular ) kunokufuneka.

2. Inkqubo ye-ICSI kwilebhu

Eli lelona xesha libalulekileyo. Kwilabhoratri, iingcali zenza oku kulandelayo:

1. Iqanda elivuthiweyo lithathwa ngobunono ngeglasi encinci kakhulu.

2. Emva koko, xa ujonga ngemakroskopu, kukhethwa isidoda esilungileyo size sibanjwe ngenaliti encinci kakhulu.

3. Ngoku inaliti ifakwa ngononophelo eqandeni kwaye isidoda sifakwa kwi- cytoplasm yeqanda.

4. Emva koko umbingeleli ukhupha inaliti.

3. Uphuhliso lwe-embryo kunye nokufakelwa kwayo kwisibeleko (Ukudluliselwa kwe-embryo)

Emva kwe-ICSI, iqanda elivundisiweyo, okanye i-embryo , lishiywa ukuba likhulele elabhoratri kangangeentsuku ezi-5 ukuya kwezi-6. Ngeli xesha, liyahlukana libe ziiseli lize lifikelele kwinqanaba elibizwa ngokuba yi-blastocyst .

Emva koko, i-embryo okanye ii-embryo ezisemgangathweni ophezulu zifakwa kwisibeleko sikamama ngetyhubhu ekhethekileyo (i-catheter) . Oku akudingi i-anesthesia. Ukuba le mbryo inamathela eludongeni lwesibeleko (ukufakelwa), ukukhulelwa kuyaphumelela. Ugqirha ucebisa ukuba kuvavanywe ukukhulelwa malunga neeveki ezimbini emva konyango.

Zithini iingenelo kunye neengozi zonyango lwe-ICSI?

Nangona kunjalo, njengakwezinye iindlela zonyango, kukho iingozi ezibandakanyekileyo, kwaye kubalulekile ukuba uzazi.

• Amanye amaqanda angonakala xa ehlatywa ngenaliti.
• Nokuba kufakwe isidoda, ngamanye amaxesha iqanda lisenokungavundiswa.
• I-embryo ephumayo ingayeka ukukhula emva kokuba ityalwe kwilebhu okanye kwisibeleko.

Iingozi ezinokubakho kumntwana:

Ezinye izifundo zibonise ukuba abantwana abazelwe bene-ICSI banomngcipheko okhulayo kancinci weemeko ezithile zokuzalwa . Nangona kunjalo, iingcali zonyango zikholelwa ukuba lo mngcipheko awubangelwa lunyango ngokwalo, kodwa ubangelwa sisizathu esiyintloko sokungazali. Ezi ngozi ziquka iimeko ezifana ne -Angelman syndrome, i-autism, kunye ne-Beckwith-Wiedemann syndrome . Nangona kunjalo, lo mngcipheko mncinci kakhulu. Thetha nogqirha wakho ngale nto.

Amathuba okuba namawele:

Ukwandisa amathuba okukhulelwa, ngamanye amaxesha kufakwa ngaphezulu kwe-embryo enye (umz. ezimbini) esibelekweni. Kwimeko enjalo, amathuba okuba namawele okanye amawele amathathu aphezulu.

Ufanele uye nini kugqirha?

Emva konyango, ukuba ufumana ezi mpawu zilandelayo, fowunela ugqirha wakho ngoko nangoko :

• Iimpawu zosulelo , ezinje ngomkhuhlane ophezulu kunye nokukhupha ulwelo olungcolileyo oluphuma kwilungu lobufazi.
• Iimpawu zokukhulelwa okuphuma ectopic (iintlungu eziqatha zesisu kwelinye icala, ukuquleka).
• Iimpawu zokuphuma kwesisu (ukopha kakhulu, iintlungu zesisu).
• Iimpawu zokuzalwa ngaphambi kwexesha .
