Blastocyst mu bufunze: Omutendera ogusooka mu lubuto olulamu (Blastocyst) .

Bw’oba ​​oli muntu alina essuubi ly’okuzaala naddala ng’ogenda mu bujjanjabi bw’obutazaala, oteekwa okuba ng’owulidde ekigambo ‘Blastocyst’ okuva ew’omusawo wo. Ekigambo kino kitera okuwulirwa naddala nga twogera ku bujjanjabi nga IVF. Kino bw’owulira, kiyinza okukulabika ng’ekitali kya ssaayansi era nga kizibu gy’oli. Naye totya. Mu ngeri ennyangu, eno y’entandikwa esinga obutono, naye nga nkulu nnyo ey’essuubi lyo. Leero, tugenda kwogera mu ngeri ennyangu ennyo era ey’omukwano ku Blastocyst eno ky’eri, ky’ekola, n’engeri gy’eri enkulu eri olubuto.

Mu ngeri ennyangu, Blastocyst kye ki?

Teebereza, eggi ly’omukazi omulamu bwe limala okuzaala ensigo z’omusajja omulamu obulungi, akatoffaali akasooka okutondebwa kayitibwa zygote. Akatoffaali ako katandika okwawukana mangu. Ekimu kifuuka bibiri, bibiri bifuuka bina, n’ebirala, ne bikola akasengejja akatono akalinga omupiira akayitibwa blastocyst .

Mu ngeri ennyangu, ekizimba ekiyitibwa blastocyst kye kiseera ekisookerwako ennyo eky’embuto . Kibaawo oluvannyuma lw’ennaku nga ttaano ku mukaaga ng’ensigo emaze okuzaala eggi. Kino kikulu nnyo mu nkola y’okufuna olubuto. Wano obutoffaali buno bwe bukwatagana ne bukwatagana ne bbugwe wa nnabaana. Kino tukiyita okuteekebwa mu mubiri.

Omutendera guno ogwa Blastocyst mukulu nnyo naddala mu IVF (In Vitro Fertilization) kubanga abasawo basobola okulonda Blastocyst esinga obulamu era esinga okukula ne bagiteeka mu nnabaana wa maama. Kino kyongera emikisa gy’okufuna olubuto olulungi.

Enkola y’okufunyisa omwana olubuto egenda etya?

Okutegeera obulungi obukulu bwa blastocyst, kiyamba okuba n’ekirowoozo ekitono ku nkola yonna ey’okufunyisa omwana olubuto. Ka tulabe engeri olugendo luno olw’ekyewuunyo gye lugenda mu maaso mutendera ku mutendera.

. Eggi lino litambula wansi mu nseke era lirindirira okuzaala ensigo.

2. Okuzaala: Singa akaboozi kabaawo mu kiseera kino, ensigo esobola okusisinkana eggi mu nseke ne yeegatta nalyo. Kino kye tuyita okuzaala.

3. Okutondebwa kwa Zygote: Eggi erifumbiddwa tugiyita ‘zygote’. Kano ke katoffaali kamu akasooka okugatta obuzaale bwa maama ne taata.

4. Olugendo okutuuka ku mutendera gwa Blastocyst:Ensigo eno egenda wansi mu nseke okutuuka mu nnabaana okumala ennaku nga ssatu oba ttaano. Tekimala gatuula awo, kisigala kyeyawulamu. Obutoffaali bubiri, buna, munaana... bweyawukana mangu ne bufuuka akapiira akatono nga kalimu ebikumi n’ebikumi by’obutoffaali n’ekituli munda. Ekyo kye tuyita Blastocyst .

5. Okuteeka mu nnabaana: Oluvannyuma lw’okutuuka mu nnabaana, ekikuta kya blastocyst kibeera eyo okumala ennaku ntono ne kyekwata ku bbugwe ow’omunda mu nnabaana (endometrium). Kino kye tuyita ‘okuteekebwamu’.

6. Embuto n’omwana ali mu lubuto: Oluvannyuma lw’okuteekebwa mu nnabaana, obutoffaali buno bweyongera okwawukana ne bukula ne bufuuka embuto. Oluvannyuma lwa wiiki nga 9, embuto eno yeeyongera okukula n’efuuka omwana ali mu lubuto, nga kino kye kifaananyi ekijjuvu eky’omwana nga bwe tukimanyi.

Omulimu gwa blastocyst gukola gutya? Lwaki kino kikulu nnyo?

Omutendera gwa blastocyst mutendera mukulu nnyo era oguteewalika mu nkula y’embuto n’omwana ali mu lubuto. Ensonga ennyangu eri nti singa blastocyst tesimbibwa bulungi mu bbugwe wa nnabaana, olubuto terujja kubaawo.

Okuteekebwa kuno kubaawo nga kuyita mu nkola ey’ekyamagero. Nga tufugibwa obusimu mu mibiri gyaffe, ekikuta kya blastocyst kiyita mu nkola eyitibwa "okuzaala." Nga enkoko bw’efuluma okuva mu ggi, ekikuta kya blastocyst kimenya oluwuzi lwayo olw’ebweru olugonvu (zona pellucida). Kino kibaawo mu lunaku lumu oba ssatu ng’eyingidde mu nnabaana.

Olwo omulimu omutuufu ne gubaawo. Mu blastocyst mulimu layers bbiri ez’obutoffaali.

• Trophoblast: Obutoffaali buno bwe busooka okwekwata ku bbugwe wa nnabaana. Kino bakikola nga bakola puloteyina ekwata (L-selectin), eringa ggaamu. Oluvannyuma obutoffaali buno bukola ekikuta . Ensigo kitundu kikulu nnyo ekiwa omwana omukka gwa oxygen n’ebiriisa n’okuggya kasasiro mu mwana.
• Obutoffaali obw’omunda: Ekibinja kino eky’obutoffaali oluvannyuma kijja kukula ne kifuuka omwana ali mu lubuto .

Obutoffaali obumu mu nnabaana bwe bukwatagana ne bukola ensawo y’omu lubuto (amniotic sac), ensawo y’amazzi ekuuma omwana eyeetoolodde omwana.

Bubonero ki obulaga nti omuntu ateekebwamu obutoffaali obuyitibwa blastocyst?

Abantu abasinga tebafuna bubonero bwonna mu kiseera kino. Naye abantu abamu, nga kimu kya kusatu, bayinza okufuna obubonero obumu. Buno buyinza okuba akabonero akasooka okulaga nti oli lubuto. Naye si buli muntu nti afuna obubonero buno, era okubeera n’obubonero buno tekitegeeza nti oli lubuto. Kale bulijjo kiba kirungi okwogera n’omusawo wo.

Blastocyst esobola okuvaamu olubuto?

Guno mulamwa gwa maanyi okwogerako, naye kikulu okumanya. Yee, ekiwuka ekiyitibwa blastocyst kisobola okuvaamu olubuto oba okulemererwa okuteekebwamu obulungi. Mu butuufu, ebitundu nga 75% eby’okuggyamu embuto nga bukyali nnyo biva ku blastocyst obutasimbibwa bulungi.

Lwaki kino kigenda mu maaso?

Ensonga enkulu lwaki kino kivaako kwe kuba nti ensengekera y’obutonde (chromosomal abnormalities).Obutoffaali obuli mu blastocyst bwe bwawukana, oluusi wayinza okubaawo obuzibu ku chromosomes. Ng’ekyokulabirako, wayinza okubaawo chromosome ey’enjawulo, chromosome ebula, oba ekitundu kya chromosome kiyinza okukutuka.

Okusimbibwa bwe kulemererwa mu ngeri eno, olubuto lusobola okutandika naye nga lukoma nga bukyali nnyo (nga wiiki 5). Kino kye tuyita "olubuto olw'eddagala." Okuggyako ng’olubuto lulwawo oba ng’okebedde olubuto, oyinza n’obutamanya nti kino kibaddewo.

Tekitera nnyo, blastocyst erimu obuzibu mu chromosomal esobola okuteekebwamu era olubuto ne lusobola okugenda mu maaso. Mu mbeera ng’ezo, waliwo akabi nti omwana ajja kuba n’embeera nga Down syndrome, Klinefelter syndrome oba Turner syndrome.

Waliwo engeri y’okuzuulamu ebizibu bino eby’ensengekera y’obutonde (chromosomal problems) nga bukyali mu kiseera kya IVF?

Yee, olw’okukulaakulana kw’obusawo obw’omulembe, waliwo eky’okugonjoola kino. Mu kiseera ky’obujjanjabi bwa IVF, nga blastocyst tennasimbibwa mu nnabaana, obutoffaali obutonotono busobola okuggyibwamu ne bukeberebwa oba temuli buzibu mu chromosomal.

Okukebera kuno kuyitibwa Preimplantation Genetic Testing (PGT) .

Nga bakozesa okukebera kuno, abasawo basobola okulonda ekirungo ekiyitibwa ‘blastocyst’ ekirimu ensengekera y’obutonde (chromosomally healthy blastocyst) okukiteeka mu nnabaana. N'olw'ekyo,

• Emikisa gy’okufuna olubuto olulungi gyeyongera.
• Obulabe bw’okuggyamu olubuto nga bukyali bukendeera.
• Kiyinza okukendeeza ku bulabe bw’okuzaala omwana alina obuzibu mu nsengekera y’obutonde (chromosomal abnormalities).

Ku muntu afuna olubuto mu butonde, okukebera okw’ekika kino osobola okukikola oluvannyuma lwa wiiki 9 oba 10 ng’ali lubuto.

Obulabe bw’obutabeera bulungi mu nsengekera y’obutonde (chromosomal abnormalities) busobola okukendeezebwa?

Ebyembi, ebimu ku bintu eby’akabi tetusobola kubifuga.

• Okubeera n’emyaka egisukka mu 35.
• Okubeera n’ebyafaayo by’amaka eby’obuzibu mu nsengekera y’obutonde (chromosomal disorders).
• Okuba nga yavaamu embuto emabegako oba okuzaala omwana alina obuzibu mu chromosomal.

Bw’oba ​​olina ebintu bino eby’obulabe, kikulu nnyo okwogera n’omusawo wo n’omubuulirizi ku by’obuzaale ng’oteekateeka okuzaala.

Kyokka, waliwo ebintu bye tusobola okufuga. Bwe tugoberera obulamu obulungi nga tetunnafuna lubuto n’oluvannyuma lw’okufuna olubuto, tusobola okukendeeza ku bulabe bw’obulabe eri omwana ali mu lubuto.

• Weewale okubeera mu bintu eby’obutwa.
• Weewale ddala okukozesa ebiragalalagala n’omwenge.
• Lya emmere ennungi.
• Ddira vitamiini ezeetaagisa ng’omusawo bw’akuwadde amagezi.

Blastocyst ntandikwa nkulu nnyo eri olubuto olulamu. Singa tekikula bulungi ne kiteekebwa mu nnabaana, olubuto terujja kubaawo. Bw’ofuna amabala oba obulumi bwonna mu ntandikwa y’olubuto, tosattira wadde okubuusa amaaso, wabula laba omusawo mu bwangu akuwe amagezi. Asobola okukukebera n’akakasa nti buli kimu kitambula bulungi.
