I-Intracytoplasmic Injection Injection (ICSI)

Yini i-Intracytoplasmic Sperm Injection (ICSI)?

I-Intracytoplasmic Sperm Injection (ICSI) inqubo lapho isidoda sifakwa khona ngqo eqandeni. Le nqubo isetshenziswa ikakhulukazi lapho amadoda enezimpawu zobudoda ezingezinhle. I-ICSI imvamisa inikezwa imibhangqwana ebikade ingenawo umanyolo ompofu noma ongazange ube nayo ngesikhathi se-IVF esejwayelekile, noma lapho umanyolo kucatshangwa ukuthi mancane amathuba okuthi kwenzeke nge-IVF ejwayelekile. I-ICSI ingabonakala njengenye yezindlela ezinkulu zekhefu ekwelashweni kokuzala inzalo yowesilisa ngoba yidlanzana nje elijwayelekile elidingekayo lokukhulelwa. Abesilisa abake babonwa njengabahlanzekile ngokuphelele manje banethuba elihle lokuba nengane yabo.

I-ICSI yaqala ukusetshenziswa kwi-1992 futhi inikeza enye indlela yokunikeza isidoda kulabo abanokulimala okunamandla kwabesilisa okubandakanya:

  • I-morphology yesidoda esibuthakathaka (isidoda esenziwe ngendlela engajwayelekile)
  • Isidoda esibuthaka isidoda (isidoda esihamba kancane)
  • Ukubalwa kwesidoda esiphansi
  • Ukuvinjwa okuvimbela ukuphuma kwesidoda (njenge-vasectomy)
  • Ama-antibodies ama-antisperm (amasosha omzimba akhiqizwa ngumzimba wendoda angavimbela ukusebenza kwesidoda)
  • Ama-Vasectomy abuyela emuva aholela ekubaleni okuncane kakhulu kwesidoda noma ukukhiqizwa kwekhwalithi empofu

E-in vitro fertilization (IVF) ejwayelekile, ephakathi kwe-50,000 ne-100,000 isidoda sibekwa esitsheni esifanayo neqanda elilodwa, futhi isidoda sivunyelwe ukuba nomquba weqanda ngokwemvelo. Esimweni lapho kungabikho khona okulimazayo kwesidoda, umquba ojwayelekile uvame ukuqinisekiswa ngakusasa ekuseni. Kodwa-ke, ezimweni zokuzala kokuzala kokuzala lapho kutholakala khona okungahambi kahle esibalweni, motility, kanye / noma ekwakhekeni kwesidoda, ama-IVF aholela emazingeni omanyolo omubi kakhulu, kuvame ukubangela ukuba kungabi namaqanda avundisiwe futhi ngenxa yalokho akukho mibungu yokudlulisa. Njengoba i-ICSI ifaka phakathi umjovo wesidoda esisodwa eqandeni ngalinye, ngisho nokulimazeka okubi kakhulu kwezici zabesilisa kunganqotshwa.

Kusetshenziswa imakroskopheni ephezulu yokukhulisa umzimba, isidoda esisodwa esifakwe enkabeni yeqanda elivuthiwe sisebenzisa inalithi engilazi enhle kakhulu izikhathi eziningi sincane kunezinwele zomuntu. Izigaba zokuqala zokwelashwa kwe-ICSI ziyefana nakwi-IVF evamile. Ohamba naye wesifazane uthatha izidakamizwa zokuzala ukuze avuselele amaqanda akhe ukuze kuqoqwe amaqanda amaningana. Lapho-ke isampula yamaduna ilungiswa kulebhu ukuhlukanisa isidoda esinempilo esiningi ngangokunokwenzeka. Isidoda siyagezwa futhi silungiselelwe ukumvundiswa. Iqanda ngalinye lifakwa ngeseli lesidoda ukuze imibungu eminingana izotholakala ukuze idluliselwe futhi igcinwe. Amaqanda afakiwe afakwa ku-incubator futhi ayahlolwa ngakusasa ukuthola izimpawu zokuzala. Sibe sesikhetha imibungu okungenzeka ikhule ibe ingane enempilo yokuyidlulisela.

Cishe i-30% kuya ku-40% lakho konke ukungaboli kungenxa yesici sowesilisa. I-ICSI iguqule ukwelashwa kokungazali kwabesilisa ngesilinganiso sokukhulelwa ezungeze i-70%. Ngenkathi i-ICSI ingakuqinisekisi ngokuphelele umanyolo, izinga lokuzala eliphelele lehle kakhulu liphansi kakhulu futhi livame kakhulu ezimweni zokuhlinzekwa kwamaqanda okulinganiselwe. Kuze kube manje, amashumi ezinkulungwane zezingane azalwe emhlabeni wonke njengomphumela we-ICSI.

Umehluko phakathi kwe-IVF ne-ICSI

Ukugqugquzela i-Ovarian nokubuyisa amaqanda ku-ICSI naku-IVF kuyefana ncamashi. Umehluko kuphela phakathi kwalokhu okubili yindlela iqanda elikhulelwa ngayo. IVF ivumela isidoda ukuthi singene eqandeni ngokwaso. Kodwa-ke kumjikelezo we-ICSI iqanda ngalinye elivuthiwe elifanele lijojowe ngeseli elilodwa lesidoda elilungiselelwe. Lokhu kwenziwa ngaphansi kwesibonakhulu ngochwepheshe abaqeqeshiwe besebenzisa amathuluzi amahle kakhulu (aziwa ngokuthi yi-micromanipulation). Uma iqanda livundiswa umbungu ufakwa esibelethweni ngendlela efanayo ne-IVF.
