Muri make, Blastocyst: Intambwe ya mbere mu gutwita neza (Blastocyst)

Niba uri umuntu wifuza kubyara, cyane cyane niba uri kuvurwa ubugumba, ugomba kuba warumvise ijambo 'Blastocyst' rivuye kwa muganga wawe. Iri jambo rikunze kumvikana, cyane cyane iyo uvuga ku bijyanye n'ubuvuzi nka IVF. Iyo ubyumvise, bishobora kugaragara nk'ibya siyansi kandi bigoye kuri wewe. Ariko ntutinye. Mu magambo make, iyi ni yo ntangiriro ntoya, ariko ikomeye cyane y'ibyiringiro byawe. Uyu munsi, turaganira mu buryo bworoshye kandi bwuje urugwiro ku cyo iyi Blastocyst ari cyo, icyo ikora, n'akamaro kayo ku gutwita.

Mu magambo make, Blastocyst ni iki?

Tekereza, nyuma y’uko igi ry’umugore muzima rihujwe n’intanga ngabo z’umugabo muzima, ingirabuzimafatizo ya mbere ikorwa yitwa zygote. Iyo ngirabuzimafatizo itangira kwigabanyamo kabiri vuba. Imwe iba ebyiri, ebyiri ziba enye, bityo bityo, igakora imiterere mito isa n’umupira witwa blastocyst .

Mu magambo make, blastocyst ni icyiciro cya mbere cy'uruhinja . Ibaho nyuma y'iminsi itanu kugeza kuri itandatu intanga ngabo zivanze n'igi. Iki ni igikorwa cy'ingenzi cyane mu gihe cyo gutwita. Ni igihe izi selile zihurira ku rukuta rw'umura. Ibi twita guteranya.

Iki cyiciro cya Blastocyst ni ingenzi cyane muri IVF (In Vitro Fertilization) kuko abaganga bashobora guhitamo Blastocyst ifite ubuzima bwiza kandi ikomeye bakayishyira mu nda ya nyina. Ibi byongera amahirwe yo gutwita neza.

Ni gute igikorwa cyo gutwita umwana kibaho?

Kugira ngo wumve neza akamaro ka blastocyst, ni byiza kugira igitekerezo gito ku buryo bwose bwo gutwita umwana. Reka turebere hamwe uburyo uru rugendo rutangaje rugenda intambwe ku yindi.

1. Gusohora intanga: Ubusanzwe nyuma y'iminsi 14 umugore atangiye imihango ye y'ukwezi, igi rikuze (intanga) riva muri imwe mu ntanga ze. Iri gi rinyura mu muyoboro w'inda rigategereza intanga ziterwa n'intanga.

2. Gutera intanga: Iyo imibonano mpuzabitsina ibaye muri iki gihe, intanga zishobora guhura n'igi mu muyoboro w'inda zikarihuza. Ibi ni byo twita gutera intanga.

3. Imiterere ya Zygote: Igi ry’intanga ngore twita 'zygote'. Uru ni rwo rugingo rwa mbere ruhuza imiterere y’uturemangingo twa nyina na se.

4. Urugendo rugana ku cyiciro cya Blastocyst:Iyi zygote inyura mu muyoboro w'inda ikagera muri nyababyeyi mu gihe cy'iminsi itatu kugeza kuri itanu. Ntiyicara aho gusa, ikomeza kwigabanyamo ibice. Uturemangingo tubiri, tune, umunani ... twigabanyamo ibice vuba kandi tukaba umupira muto ufite amagana y'uturemangingo n'umwobo imbere. Ibyo ni byo twita Blastocyst .

5. Gutera intanga: Nyuma yo kugera mu mura, blastocyst iguma aho iminsi mike ikayifata ku rukuta rw'imbere rw'umura (endometrium). Ibi nibyo twita 'gutera intanga'.

6. Intanga ngore n'umwana uri mu nda: Nyuma yo gushyirwa mu mura, utwo turemangingo dukomeza kwigabanyamo ibice no gukura tukaba inda. Nyuma y'ibyumweru bigera kuri 9, iyi nda irakura cyane ikaba inda, ari na yo shusho yuzuye y'umwana nkuko tuyizi.

Akamaro ka blastocyst ni akahe? Kuki ibi ari ingenzi cyane?

Icyiciro cya blastocyst ni ingenzi cyane kandi ntigishobora kwirindwa mu mikurire y'umwana uri mu nda n'umwana uri mu nda. Impamvu yoroshye ni uko iyo blastocyst idateye neza mu rukuta rw'umura, nta gutwita bizabaho.

Uku guterana kw'uturemangingo bibaho binyuze mu buryo bw'igitangaza. Bitewe n'imisemburo mu mibiri yacu, blastocyst inyura mu buryo bwitwa "gukura." Nk'uko umwana w'inkoko ava mu gi, blastocyst inyura mu ruhu rwo hanze (zona pellucida). Ibi bibaho mu munsi umwe cyangwa itatu uhereye igihe yinjiriye mu mura.

Hanyuma akazi nyakuri karatangira. Hari ibice bibiri by'uturemangingo muri blastocyst.

• Trophoblast: Utu tunyangingo ni two twa mbere dufata ku rukuta rw'umura. Tubikora dukora poroteyine ifata (L-selectin), imeze nk'umukara. Utu tunyangingo nyuma tugakora placenta . Placenta ni urugingo rw'ingenzi cyane rutanga ogisijeni n'intungamubiri ku mwana kandi rugakura imyanda ku mwana.
• Ubwinshi bw'uturemangingo tw'imbere: Ubu bwinshi bw'uturemangingo buzakura nyuma bugahinduka umwana uri mu nda.

Uturemangingo tumwe na tumwe two muri placenta turaterana tugakora agafuka k'amazi gakingira umwana.

Ni ibihe bimenyetso by'uko blastocyst ishyirwa mu mubiri?

Abantu benshi ntibagira ibimenyetso muri iki gihe. Ariko hari abantu bamwe, hafi kimwe cya gatatu, bashobora kugira ibimenyetso bimwe na bimwe. Ibi bishobora kuba ikimenyetso cya mbere cy'uko utwite. Ariko si buri wese ubibona, kandi kugira ibi bimenyetso ntibivuze ko utwite. Rero ni byiza kuvugana na muganga wawe.

Ese Blastocyst ishobora gutera gukuramo inda?

Iyi ni ingingo ikomeye yo kuganiraho, ariko ni ngombwa kubimenya. Yego, blastocyst ishobora gukuramo inda cyangwa inanirwa gutera inda neza. Mu by'ukuri, hafi 75% by'inda zivuka hakiri kare ziterwa n'uko blastocyst idatera inda neza.

Kuki ibi bibaho?

Impamvu nyamukuru ibi ni ubusembwa bw'uturemangingo tw'amaraso.Iyo uturemangingo turi muri blastocyst twigabanyijemo kabiri, hari igihe hashobora kubaho ibibazo kuri chromosomes. Urugero, hashobora kubaho chromosome y'inyongera, chromosome ibura, cyangwa igice cya chromosome gishobora gucika.

Iyo gutera inda binaniranye muri ubu buryo, gutwita bishobora gutangira ariko bigahagarara hakiri kare cyane (hafi ibyumweru 5). Ibi ni byo twita "gutwita hakoreshejwe imiti." Keretse igihe cyawe cyo kujya mu mihango cyatinze cyangwa wakoze ikizamini cyo gutwita, ushobora no kutamenya ko ibi byabaye.

Ni gake cyane, blastocyst ifite ikibazo cya chromosome ishobora gutera inda, inda igakomeza gutwita. Muri ibyo bihe, hari ibyago by'uko umwana yagira indwara nka Down syndrome, Klinefelter syndrome, cyangwa Turner syndrome.

Ese hari uburyo bwo kumenya ibi bibazo bya chromosomes mbere y'igihe mu gihe cya IVF?

Yego, hamwe n’iterambere ry’ubuvuzi bwa none, hari igisubizo kuri ibi. Mu gihe cyo kuvura IVF, mbere yuko blastocyst ishyirwa mu mura, uturemangingo duke dushobora gukurwamo tugapimwa ibibazo bya chromosomes.

Iki kizamini cyitwa Preimplantation Genetic Testing (PGT) .

Muri iki kizamini, abaganga bashobora guhitamo blastocyst ifite ubuzima bwiza kurusha izindi mu maraso kugira ngo bayishyire mu mura.

• Amahirwe yo gutwita neza ariyongera.
• Ibyago byo gukuramo inda hakiri kare biragabanuka.
• Bishobora kugabanya ibyago byo kubyara umwana ufite ibibazo bya chromosomes.

Ku muntu utwite mu buryo busanzwe, ubwo bwoko bw'ibizamini bushobora gukorwa gusa nyuma y'ibyumweru 9 cyangwa 10 atwite.

Ese ibyago byo kutagira imikorere myiza ya chromosomes bishobora kugabanuka?

Ikibabaje ni uko hari ibintu bimwe na bimwe bishobora gutera ibyago tudashobora kubigenzura.

• Kuba ufite imyaka irenga 35.
• Kugira amateka y'umuryango ku ndwara za chromosomes.
• Kuba warigeze gukuramo inda mbere cyangwa kubyara umwana ufite ikibazo cy’uturemangingo tw’amaraso.

Niba ufite ibi bintu bishobora gutera ibyago, ni ngombwa cyane kuvugana na muganga wawe n'umujyanama mu by'uturemangingo mu gihe uteganya kubyara umwana.

Ariko hari ibintu dushobora kugenzura. Dukurikije ubuzima bwiza mbere na nyuma yo gutwita, dushobora kugabanya ibyago byo kwangiza umwana uri mu nda.

• Irinde guhura n'ibintu bihumanya.
• Irinde burundu gukoresha ibiyobyabwenge n'inzoga.
• Kurya indyo yuzuye.
• Fata vitamine zikenewe nk'uko muganga wawe yabigutegetse.

Blastocyst ni intangiriro y'ingenzi yo gutwita neza. Iyo idakuze neza kandi ikamera mu mura, gutwita ntibizabaho. Niba ubonye uduheri cyangwa ububabare mu ntangiriro zo gutwita, ntugatinye cyangwa ngo ubyirengagize, ahubwo gana muganga wawe vuba kugira ngo akugire inama. Ashobora kugusuzuma no kwemeza ko byose bigenda neza.
