Lub tswvyim ntawm "vitrification ntawm oocytes" - nws yog dab tsi?

Yuav kom nkag siab tias cov txheej txheem vitrification ua haujlwm li cas, nws yog ib qho tsim nyog yuav tsum muaj kev nkag siab txog hauv vitro fertilization. Cov txheej txheem no suav nrog kev sau cov poj niam kab mob hlwb (oocytes) los ntawm zes qe menyuam. Tom qab ntawd lawv raug ntxuav thiab fertilized nrog tus khub lossis cov phev pub dawb (yog tias tus txiv tsis muaj menyuam). Tom qab ntawd, lub zygote uas pib faibmuab tso rau hauv lub uterine kab noj hniav. Oocyte vitrification yog txheej txheem zoo ib yam li qe cryopreservation. Txawm li cas los xij, nws yog qib siab dua. Vitrification yog hais txog kev khov ntawm cov kab mob uas tsis paub tab. Yog li ntawd, oocytes tuaj yeem khaws cia rau lub sijhawm ntev. Txawm hais tias lub xeev "frozen", vitrified hlwb tseem siv tau. Cov txheej txheem no suav hais tias yog kev ua txhaum loj hauv cov tshuaj, vim tias ua tsaug rau nws, cov poj niam muaj lub cib fim kom muaj menyuam txawm tias tsis muaj lub cev xeeb tub.

Lub hom phiaj ntawm oocyte vitrification yog dab tsi?

Nyob rau hauv cov teb chaws Europe, xws li cov ntsiab lus xws li cryopreservation, vitrification ntawm embryos thiab oocytes tau paub ntev lawm. Qhov no tuaj yeem raug txiav txim los ntawm cov yeeb yaj kiab Western uas mob siab rau tshuaj. Hauv cov teb chaws ntawm qhov chaw tom qab-Soviet, cov kws kho mob kuj paub txog cov ntsiab lus no rau ntau xyoo lawm. Txawm li cas los xij, cov txheej txheem no tsuas yog nyuam qhuav dhau los ua rau cov neeg mob. Feem ntau, oocyte vitrification yog ua rau hauv vitro fertilization.

Rau qhov pathologies yog qe vitrification pom zoo?

Vitrification ntawm oocytes thiab embryos yog txoj kev them nyiaj muaj rau txhua tus. Tsis muaj kev qhia tshwj xeeb rau nws, txawm li cas los xij, nws yog qhov tsim nyog tsuas yog hauv cov xwm txheej tshwj xeeb. Qhov no tsis tau txhais hais tias qee tus poj niam tsis tuaj yeem them taus kom lawv cov cell vitrified. Txawm li cas los xij, yog tias tsis muaj laj thawj rau khov oocytes hauv txoj kev no, cryopreservation raug pom zoo rau cov neeg mob. Feem ntau, vitrification yog ua raws li cov hauv qab no:

  1. Npaj rau oophorectomy. Qhov kev ua haujlwm no yog ua rau mob qog noj ntshav ntawm zes qe menyuam thiab xav tias nws txoj kev loj hlob. Qhov laj thawj no tsis tshwm sim ntau, vim feem ntau, nrog rau cov kab mob oncogynecological, lub tsev menyuam kuj raug tshem tawm.
  2. Tsis muaj peev xwm kom tau cov spermatozoa rau hnub ntawm oocyte retrieval. Vim li no, cov hlwb yuav tsum tau khov kom txog thaum muaj cov khoom fertilization.
  3. kab mob Oncological ntawm ib cheeb tsam. Txawm hais tias nyob qhov twg muaj cov qog nqaij hlav cancer, kev kho hluav taws xob thiab kev kho mob nrog tshuaj (cytostatic) yuav tsum tau ua. Nrog rau txhua txoj hauv kev no, kev xeeb tub yog qhov tsis xav tau. Tom qab tag nrho, cov kev kho mob zoo li no rhuav tshem tsis tau tsuas yog cov qog nqaij hlav cancer xwb, tab sis kuj cov hlwb noj qab haus huv, suav nrog oocytes.
  4. Cov poj niam xav kom muaj menyuam hauv lub sijhawm ntev, piv txwv li, tom qab lub cev tsis muaj zog. Nyob rau hauv xws li mob, cryopreservation tsis tshua muajtsim tau, txij li cov qe nrog txoj kev khov no tsis tuaj yeem siv tau ntev. Yog li, cov kws kho mob muab lwm txoj hauv kev - vitrification ntawm oocytes.
  5. Rov ua IVF, yog tias thawj zaug cov qe tsis tau cag. Hauv qhov no, lawv muab vitrification kom tsis txhob nqa cov khoom peb zaug.
