Amanqanaba okukhulelwa kunye nobudala

Ubudlelwane phakathi kobudala kunye nokuzala kwabasetyhini kudla ngokubizwa ngokuba "liwotshi yendalo" yomfazi; xa umntu obhinqileyo efikelela kubudala apho ukuchuma kuqheleke ukuqondwa njengokuhla, kunokuthiwa "iwotshi yakhe yebhayoloji iyangxama.

Bonke abantu basetyhini bazalwa benamaqanda agqityiweyo, ngokude kuthi ga kwisigidi esinye. Ngexesha lokufikisa kufikelelwa kwinani lamaqanda ancitshiswe afikelele kwi500,000. Ukusukela ekukhuleni (ukujikeleza iminyaka eyi-12) ukuya esikhathini sokuya esikhathini (malunga nobudala be-51 +) kukho ukuqhubekeka okuqhubekekayo kwenani leqanda kunye nomgangatho kwii-ovari, kwaye ke ukwehla kwesibalo se-ovarian kunye namandla okuzala. Iqondo lokulahleka kwee-oocytes ngaphakathi kwe-ovary limiselwe kwangaphambili ngokwemfuza. Abanye abantu basetyhini baya kuva ukwehla okukhulu kwinani lee-oocytes zabo kwimifanekiso yabo, ngelixa abanye banokufumana oku ngaphambili.

Ukuchuma kwentsholongwane kubafazi abaninzi kwii-20s zabo, kwaye ngokuthe ngcembe ziqala ukwehla kwii-20s ezipheleyo. Kwiminyaka ekufutshane ye-35, ukuchuma kuqalisa ukwehla ngesantya esikhawulezayo. Njengoko usaluphala kwaye usondela ekuyekeni ukuya esikhathini, amaqanda akho aphendula kakuhle kwiihomoni anoxanduva lokukhupha amaqanda. Uphando lufumanise ukuba kuyo nayiphi na inyanga inyanga amathuba akho okuba ukhulelwe ngo:

Ubudala 20 - 35 malunga ne25%

Ubudala 35 - 39 malunga ne18%

Yobudala 40 malunga ne5%

Ukukhulelwa kwi-20 yakho

Uninzi lwabasetyhini kwi-20 yabo banotshintsho oluhle kakhulu lokukhulelwa ngenxa yokuba nenani elikhulu lamaqanda kwii-ovari zabo. Ukongeza, ipesenti enkulu yamaqanda aqhelekile ngokwemfuza, ekhokelela kwithuba elikhulu lokuchumisa kunye nokukhulelwa ngempumelelo. Njengabafazi ababudala, banamaqanda ambalwa aseleyo ngelixa ipesenti yamaqanda oofuzo ahlala esehla.

Ireyithi yokukhulelwa ngenyanga yomfazi okwi-20 yakhe malunga ne25%. Ngelixa kuyacetyiswa ukuba kubonwe ingcali yokuchuma emva kokuzama ngokungazami ukuba ukhulelwe ngaphezulu kweenyanga ze-12, kwikliniki yezonyango yaseMedfem sikhuthaza abantu ukuba babhukishe ukubonisana ngokukhawuleza nje ukuba baziva nangayiphi na indlela ixhala lokuzala. 

Amathuba okujongwa kwemfuza efana ne-Down syndrome imalunga ne-1 / 1200 kumfazi okwi-20 yakhe. 

Ukukhulelwa kwi-30 yakho yokuqala

Abasetyhini abakwiminyaka engama-30 ubudala baya kuba nokwehla kokuchuma kwabo kangangokuba inqanaba lokuchuma ngenyanga liya kuba sezantsi kunakwiminyaka yama-20. Kwakhona, ngelixa kuqhelekile kucetyiswa ukubona ingcali yenzala emva kokungaphumeleli ukuzama ukukhulelwa ngaphezulu kweenyanga ezili-12, kwiklinikhi yokuChuma kweMedfem sikhuthaza abantu ukuba babhukishe ukubonisana kwangoko baziva bexhalabile nangayiphi na indlela malunga nokuzala kwabo. Umngcipheko wokukhulelwa kwesisu ngowama-30 umalunga neepesenti ezingama-20, kwaye umngcipheko wokungaqheleki kofuzo ungaphezulu kancinci kunabafazi abakwiminyaka yama-20.

Ukukhulelwa ngexesha lakho lokugqibela le-30's

Abafazi abakwindla yobuso babo be-30 ukwehla okuphawulekayo kwinqanaba lokuzala, ukuya kuthi ga kwi-18% ngenyanga. Ngelixa kuyacetyiswa ukuba kubonwe ingcali yokuchuma emva kokuzama ngokungazami ukukhulelwa iinyanga ze-6, kwikliniki yezonyango yaseMedfem sikhuthaza abantu ukuba babhukishe ukubonisana ngokukhawuleza nje ukuba baziva nangayiphi na indlela ixhala lokuzala.

Umngcipheko wokukhulelwa kwabasetyhini abakwiminyaka yabo yokugqibela ye-30 uphezulu kakhulu kunabasetyhini abancinci, oku kungqinwa kukunyuka kwenqanaba lokungahambi kakuhle kunye neqondo eliphakamileyo lokuxhatshazwa kwemfuza. Kwi-35 + ireythi yokuphulukiswa kwesisu iphantse ibe yi-25% kwaye umngcipheko we-Downs syndrome uba malunga ne-1 / 350. 

Ukukhulelwa kwi-40 yakho yokuqala

Kukho ukwehla okukhulu kakhulu kumandla omfazi wokukhulelwa kube kanye ngaphezulu kweminyaka engama-40. Inqanaba lokuchuma ngenyanga limalunga ne-5% kuphela ngenyanga kwaye nakwi-IVF inqanaba lokukhulelwa limalunga ne-10% kuphela ngetrayi. Oku kungenxa yenani elincitshisiweyo lamaqanda aqhelekileyo ashiyekileyo kumaqanda kumfazi ngaphezulu kwamashumi amane. Umngcipheko wokukhulelwa kwabasetyhini abakwiminyaka engama-40 ubudala ubuye uphakame kakhulu, ngamazinga okuphuphuma kwesisu angama-35%, kunye nomngcipheko we-Downs syndrome malunga ne-1/38. Ngesi sizathu, uninzi lwabasetyhini kwi-40 yabo bakhetha ukusebenzisa umnikeli weqanda ukuba akhulelwe, ngenqanaba lempumelelo malunga ne-80% kumjikelo ngamnye. Kwezi meko, njengoko amaqanda asetyenzisiweyo evela kubafazi abancinci kakhulu, inqanaba lokuphuma kwesisu kunye nokungaqheleki kwemfuza ikwangumfazi omncinci.

Ukukhulelwa ngexesha lakho lokugqibela le-40's

Ukukhulelwa kwabasetyhini abangaphezu kweminyaka engama-45 sisindululo esinzima kakhulu. Abasetyhini ngaphezulu kwe-45 banamathuba angaphantsi kwe-1% okukhulelwa ngamaqanda abo. Oku ikakhulu kungenxa yokuba uninzi lwamaqanda aseleyo aqhelekile kwimfuza. Uninzi lwabasetyhini kule minyaka yobudala bakhetha ukusebenzisa amaqanda abanikeli ukuba bakhulelwe. 

Umfazi oneminyaka eyi-45 + owakhulelwa awakhe amaqanda ajongene nengozi yokukhulelwa ye-50% nangaphezulu. Isimo sokukhulelwa okuqhelekileyo kwimvelo yi-1 kwi-12. Kukho nomngcipheko owandileyo kwimpilo yowasetyhini ngenxa yoxinzelelo lwegazi oluphezulu, isifo sentliziyo nesifo seswekile.
