Umxholo

Uninzi lwethu luhle kakhulu kwimizimba yethu. Umzekelo, ungalatha kwangoko kuloo ndawo iqine egxalabeni lakho lasekunene elidibanisa xa uxinene.

Nangona kunjalo, ungathanda ukwazi okuninzi ngakumbi malunga nokwenzekayo ngaphakathi emzimbeni wakho, njengokuthi, "Yintoni ibali emva kwamaqanda am?"

Ngaba abantwana ababhinqileyo bazalwa benamaqanda?

Ewe, abantwana ababhinqileyo bazalwa benazo zonke iiseli zamaqanda abaya kuba nazo. Hayi iiseli zeqanda ezintsha zenziwa ngexesha lokudla kwakho ubomi.

Oku kudala kwamkelwa njengenyaniso, nangona kunjalo inzululwazi yebhayoloji yokuzala uJohn Tilly wanikezela ngophando ngo-2004 okwaqala ukubonakaliswa ukubonisa iiseli ezintsha zamaqanda kwiimpuku.

Le ithiyori iphikisiwe ngokubanzi luluntu ngokubanzi, kodwa kukho iqela elincinci labaphandi abalandela lo msebenzi. (Inqaku le2020 kwiNzululwazi lichaza ingxoxo.)

I-FYI: Isigama seqanda

Iqanda elingekavuthwa libizwa ngokuba ngu oocyte. IiOocyte zihleli ngaphakathi iifollic (iisaka ezigcwaliswe lulwelo eziqukethe iqanda elingavuthwanga) kwii-ovari zakho de zibe ziqala ukukhula.


I-oocyte ikhula ibe yi ootid kwaye ikhule ibe yifayile ye- iqanda (ubuninzi: ova), okanye iqanda eliqolileyo. Kuba le ayisiyiyo inzululwazi yesayensi, siya kubambelela ikakhulu kwigama esiqhelene kakhulu nalo - iqanda.

Mangaphi amaqanda abantu ababhinqileyo abazalwa nawo?

Njengosana olungekazalwa ekukhuleni, umntu obhinqileyo ujikeleze amaqanda ezigidi ezi-6.

Inani lala maqanda (iiprotoksi, Ukuchaneka) kuncitshiswa ngokuzinzileyo ukuze xa kuzalwa usana oluyintombazana, lube namaqanda aphakathi kwesigidi esinye nesi-2. (Imithombo yahlukile kancinane, kodwa ngaphandle kwayo, sithetha nge amanani asixhenxe inani!)

Kutheni ke ngoku ukuba sexesheni kungaqali ekuzalweni?

Umbuzo olungileyo. Amaqanda akhona, ke yintoni ethintela umjikelo wokuya esikhathini ukuba ungaqali?

Umjikelo wokuya exesheni ubanjiwe de intombazana ifikelele ebusheni. Ukufikisa kuqala xa i-hypothalamus kwingqondo iqala ukuvelisa i-hormone ekhupha i-gonadotropin (GnRH).


Kwelinye icala, i-GnRH ivuselela i-pituitary gland ukuba ivelise i-follicle-evuselela i-hormone (FSH). I-FSH iqala ukukhula kweqanda kwaye ibangele amanqanaba e-estrogen anyuke.

Ngayo yonke le nto iqhubeka ngaphakathi kuthi, ayimangalisi into yokuba abanye bethu behlelwe kukutshintsha kwemeko!

Ukuzibuza ngophawu lokuqala lokufikisa? Ukuya exesheni kuqala malunga neminyaka emi-2 emva kokudumba kwebele-loo ntwana yeethishu ikhula ibele- iyavela. Ngelixa i-avareji yobudala ili-12, abanye banokuqala ukuqala nge-8, kwaye uninzi luya kuqala nge-15.

Intombazana inamaqanda amangaphi xa ifikisa?

Xa intombazana ifikisa, iba namaqanda aphakathi kwama-300,000 nama-400,000. Hee, kwenzeke ntoni kula maqanda aseleyo? Nantsi impendulo: Ngaphambi kokufikisa, ngaphezulu kwe-10 000 kufa inyanga nganye.

Mangaphi amaqanda aphulukana nomntu wasetyhini kwinyanga nganye emva kokufikisa?

Iindaba ezimnandi zezokuba inani lamaqanda afayo inyanga nenyanga liyancipha emva kokufikisa.

Emva kokuqalisa ukuya exesheni, umfazi uphulukana namaqanda ayi-1 000 (engekakhula) ngenyanga, ngokukaGqirha Sherman Silber, owayebhala incwadi ethi “Beating Your Biological Clock,” isikhokelo kwizigulana zakhe zekliniki yokungachumi. Imalunga nama-30 ukuya kuma-35 ngosuku.


Izazinzulu aziqinisekanga ngento eyenza ukuba oku kwenzeke, kodwa ziyazi ukuba ayichaphazeli kwizinto ezininzi esinokuzilawula. Ayichukunyiswa zihomoni zakho, iipilisi zokulawula ukuzalwa, ukukhulelwa, izongezo zesondlo, impilo, okanye nokutya kwakho itshokholethi.

Ezinye iimeko: Ukutshaya kukhawulezisa ukulahleka kweqanda. Ezinye iichemotherapies kunye nemitha ziyenza.

Nje ukuba iifollic zikhule, ekugqibeleni ziye zithathele ingqalelo iihomoni zomjikelo wakho wokuya exesheni. Nangona kunjalo, ayingabo bonke abaphumeleleyo. Qanda kuphela iqanda elinye. (Ngokwesiqhelo, ubuncinci. Kukho izinto ezizodwa, ezithi ngamanye amaxesha zikhokelele kumawele obuzalwana.)

Mangaphi amaqanda umntu wasetyhini aneminyaka engama-30?

Ngokunikwa amanani, xa umntu wasetyhini efikelela kuma-32, ukuzala kwakhe kuqala ukwehla kwaye kuyehla ngokukhawuleza emva kwama-37. Ngexesha afikelela kuma-40, ukuba ufana noninzi lwethu, uya kube sele ephantsi malunga nokunikezelwa kweqanda kwangaphambi kokuzalwa .

Idibeneyo: Yintoni oyaziyo kuma-20s, 30s, no-40 malunga nokukhulelwa

Mangaphi amaqanda umntu wasetyhini anama-40?

Ke ubethile i-40. Akukho mpendulo-ubungakanani bayo yonke amaqanda oshiyekileyo. Ngaphezulu, izinto ezithile-njengokutshaya-kunokuthetha ukuba unembalwa kunomnye umfazi.

Uphando lubonise ukuba umfazi ophakathi unethuba elingaphantsi kweepesenti ezintlanu zokukhulelwa kumjikelo ngamnye. Umyinge weminyaka yokuyeka ukuya kwi-52.

Crunch amanani kwaye uyabona ukuba xa kuphela amaqanda angama-25,000 ashiyekileyo kwii-ovari (malunga neminyaka engama-37), uneminyaka emalunga ne-15 de ufike exesheni, ngokomndilili. Abanye baya kubetha ukuya exesheni ngaphambili, kwaye abanye baya kubetha kamva.

Idibeneyo: Yintoni omele uyazi malunga nokuba nomntwana kwi-40

Kutheni umgangatho weqanda uncipha njengoko sikhula?

Sithethile kakhulu malunga ubungakanani yamaqanda onawo. Kodwa uthini nge umgangatho?

Ngaphambi nje kwe-ovulation inyanga nenyanga, amaqanda akho aqala ukwahlula.

Amaqanda amadala athambekele ngakumbi kwiimpazamo ngexesha lenkqubo yokwahlulahlula, isenza ukuba kube lula ukuba ziya kuba ne-chromosomes ezingaqhelekanga. Yiyo loo nto amathuba okuba usana olune-Down syndrome kunye nokunye ukukhula okungaqhelekanga kukhule njengoko ukhula.

Unokucinga ngeqanda lakho eligciniweyo njengomkhosi omncinci. Amajoni omeleleyo akwimigca engaphambili. Njengoko iminyaka iqhubeka, amaqanda akho ayavuthwa okanye alahlwe, kwaye amadala, asezantsi asezantsi.

Kuqhubeka ntoni ngamaqanda akho exesheni?

Xa uphelelwa kukubonelela ngamaqanda asebenzayo, amaqanda akho aya kuyeka ukwenza i-estrogen, kwaye uya kuyeka ukuya exesheni. Ngokuchanekileyo xa oku kusenzeka kuxhomekeke kwinani lamaqanda owazalwa unawo.

Khumbula ukuba umahluko phakathi kwesigidi esinye okanye ezi-2? Ukuba uzalwe unenani elikhulu lamaqanda, unokuba phakathi kwabafazi abakwaziyo ukuba nabantwana bendalo ngokwendalo ukuya kuthi ga embindini okanye nokuba phakathi kweminyaka engama-40.

Idibeneyo: Ukuba nomntwana kwi-50

Ukuthatha

Ngaba unengxaki yokukhulelwa? Ngoku ukuba unamanani, uya kube uxhobele ngcono ukuxoxa ngeendlela ozikhethileyo kwi-OB yakho.

Ukuba ukhathazekile ukuba ixesha alikho kwicala lakho, indlela enye onokucinga ngayo kukuqanda amaqanda akho, i-oocyte vitrification okanye ulondolozo lokuchuma lokukhetha (EFP).

Abasetyhini abaninzi abajonga i-EFP bakhuthazwa kukukhawulwa kwewotshi yabo yebhayiloji. Abanye banokuba malunga nokuqala unyango lwe-chemotherapy olunokuchaphazela ukuzala kwabo. (Qaphela: Ukuqanda iqanda ngaphambi kokuba i-chemo ingathathelwa ngqalelo "njengokhetho," njengoko kubonisiwe kulondolozo lokuchuma kwezonyango.)

Ukujonga i-EFP? Ngokomnye umthombo, amathuba akho okuba nomntwana kunye namaqanda akho aqanduselweyo angcono ukuba ubanda ngaphambi kokuba ube nama-35.

Ezinye iitekhnoloji zokuzala, ezinje nge-vitro fertilization, ikwavumela abasetyhini abakwi-40s-kwaye nakwi-50s-ukuba bafeze ukukhulelwa.

Nceda uqaphele ukuba i-IVF enamaqanda akho akunakulindeleka ukuba ibe yeyokukhetha umfazi ongazaliyo odlulileyo kwiminyaka yakhe yama-40. Nangona kunjalo, amaqanda abanikeli abasetyhini abasetyhini banokuvumela abantu basetyhini abakwi-40 ukuya kuma-50 ukuba bakhulelwe.

Thetha nogqirha wakho kwangoko kwaye rhoqo malunga nezicwangciso zokuchuma kunye nendlela ukuchuma okunokutshintsha ngayo ngokuhamba kwexesha. Yazi ukuba unokukhetha.
