Abaningi bethu bahambisana kahle nemizimba yethu. Isibonelo, ungahle ukhombe kuleyo ndawo eqinile ehlombe lakho lokunene eliba ifindo uma usushubile.

Kodwa-ke, ungathanda ukwazi okuningi kakhulu ngokwenzekayo emzimbeni wakho, njengokuthi, "Iyini indaba engemuva kwamaqanda ami?"

Ngabe izingane zesifazane zizalwa zinamaqanda?

Yebo, abantwana besifazane bazalwa benawo wonke amangqamuzana amaqanda abazoba nawo. Cha amaseli amaqanda amasha enziwa ngesikhathi sokuphila kwakho.

Lokhu kudala kwamukelwa njengeqiniso, kepha isazi sezinto eziphilayo sokuzala uJohn Tilly wanikela ngocwaningo ngo-2004 okwaqale kwavela ukuthi kukhombisa amaseli amasha amaqanda kumagundane.

Le mbono ngokuvamile iphikisiwe ngumphakathi wesayensi obanzi, kepha kuneqembu elincane labacwaningi abalandela lo msebenzi. (I-athikili ka-2020 kwiThe Scientist ichaza impikiswano.)

I-FYI: Isichazamazwi samaqanda

Iqanda elingavuthiwe libizwa ngokuthi yi oocyte. Ama-oocyte ahlala ngaphakathi izintandokazi (amasaka agcwele uketshezi aqukethe iqanda elingavuthiwe) kumaqanda akho aze aqale ukuvuthwa.

I-oocyte ikhula ibe yi ootid bese ikhula ibe yi iqanda (ubuningi: ova), noma iqanda elivuthiwe. Njengoba lokhu kungeyona inkambo yesayensi, ikakhulukazi sizonamathela egameni esilijwayele kakhulu - iqanda.

Bangaki amaqanda abantu besifazane abazalwa benabo?

Njengombungu ekuqaleni kokukhula, owesifazane unamaqanda angama-6 wezigidi.

Inani lala maqanda (ama-oocyte, ukucacisa) kuncishiswa ngokuqinile ukuze kuthi lapho kuzalwa ingane yentombazane, ibe namaqanda aphakathi kwesigidi esisodwa no-2. (Imithombo yehluka kancane, kepha noma ngabe kunjalo, sikhuluma nge izinombolo eziyisikhombisa isibalo!)

Manje kungani umjikelezo wokuya esikhathini ungaqali lapho kuzalwa?

Umbuzo omuhle. Amaqanda akhona, ngakho-ke yini evimba umjikelezo wokuya esikhathini ukuqala?

Umjikelezo wokuya esikhathini umile kuze kube yilapho intombazane ifinyelela ebusheni. Ukuthomba kuqala lapho i-hypothalamus ebuchosheni iqala ukukhiqiza i-hormone ekhipha i-gonadotropin (GnRH).

Ngokulandelayo, i-GnRH ivuselela indlala yepituitary ukuthi ikhiqize i-follicle-stimulating hormone (FSH). I-FSH iqala ukukhula kwamaqanda futhi ibangele ukuthi amazinga e-estrogen akhuphuke.

Ngalokhu konke kwenzeka ngaphakathi kithi, akumangazi ukuthi abanye bethu babhekana nokushintshashintsha kwemizwelo okuhambisanayo!

Uzibuza ngesibonakaliso sokuqala sokuthomba? Ukuya esikhathini kuqala cishe eminyakeni emi-2 ngemuva kokuhluma kwebele - kuvele leso sicubu esincane sethenda esikhula sibe yisifuba. Ngenkathi isilinganiso seminyaka eyi-12, abanye bangaqala ngaphambi kweminyaka engu-8, futhi iningi lizoqala lineminyaka engu-15.

Intombazane iba namaqanda amangaki lapho isifikile ebusheni?

Lapho intombazane ifinyelela ebusheni, iba namaqanda aphakathi kuka-300,000 no-400,000. Hawu, kwenzakalani ngawo wonke lawo maqanda? Nayi impendulo: Ngaphambi kokuthomba, kufa abangaphezu kuka-10 000 inyanga ngayinye.

Owesifazane ulahlekelwa ngamaqanda amangaki inyanga ngayinye ngemuva kokuthomba?

Izindaba ezinhle ukuthi inani lamaqanda afayo inyanga ngayinye liyancipha ngemuva kokuthomba.

Ngemuva kokuqala umjikelezo wakhe wokuya esikhathini, owesifazane ulahlekelwa amaqanda angaba yinkulungwane (angavuthiwe) njalo ngenyanga, ngokusho kukaDkt Sherman Silber, obhale i- "Beating Your Biological Clock," umhlahlandlela weziguli zakhe zasekliniki ezingazali. Lokho cishe kungu-30 kuye ku-35 ngosuku.

Ososayensi abaqiniseki ukuthi yini eyenza lokhu kwenzeke, kodwa bayazi ukuthi ayithonywa izinto eziningi esingazilawula. Akuthonywa ngamahomoni akho, amaphilisi okulawula ukubeletha, ukukhulelwa, izithasiselo zokudla okunempilo, impilo, noma nokudla kwakho ushokoledi.

Okunye okuhlukile: Ukubhema kusheshisa ukulahleka kweqanda. Ama-chemotherapies athile kanye nemisebe nakho kuyakwenza.

Lapho ama-follicles esekhulile, ekugcineni azwela kuma-hormone womjikelezo wakho wokuya esikhathini. Kodwa-ke, akubona bonke abaphumelele. Iqanda elilodwa kuphela elikhipha amaqanda. (Imvamisa, okungenani. Kukhona okuhlukile, kwesinye isikhathi okuholela kumawele obuzalwane.)

Owesifazane unamaqanda amangaki eminyakeni engama-30?

Njengoba kunikezwe izinombolo, lapho owesifazane efika kuma-32, ukuzala kwakhe kuqala ukwehla futhi kwehle ngokushesha okukhulu ngemuva kwama-37. Lapho efika kuma-40, uma efana nabanye bethu, uzobe esesondele ekunikezelweni kweqanda lakhe ngaphambi kokuzalwa .

Okuhlobene: Okufanele ukwazi kuma-20s, 30s, kanye nama-40s akho mayelana nokukhulelwa

Owesifazane unamaqanda amangaki eminyakeni engama-40?

Ngakho ushaye ama-40. Ayikho impendulo elingana nobukhulu bokuthi ushiye amaqanda amangaki. Ngaphezu kwalokho, izici ezithile - ezifana nokubhema - zingasho ukuthi unezibalo ezimbalwa kunomunye wesifazane.

Ucwaningo lukhombisile ukuthi owesifazane ojwayelekile unethuba elingaphansi kwamaphesenti amahlanu lokukhulelwa ngomjikelezo ngamunye. Isilinganiso seminyaka yokunqamuka kokuya esikhathini sineminyaka engama-52.

Qoqa izinombolo futhi uyabona ukuthi uma kuphela amaqanda angama-25,000 asele kuma-ovari (aneminyaka yobudala engama-37), uneminyaka engaba ngu-15 uze ufike esikhathini sokuya esikhathini, ngokwesilinganiso. Abanye bazoshaya ukuya esikhathini ekuqaleni, kanti abanye bazokushaya kamuva.

Okuhlobene: Okufanele ukwazi ngokuba nomntwana eneminyaka engama-40

Kungani izinga leqanda lehla njengoba sikhula?

Sesikhulume kakhulu nge ubuningi amaqanda onawo. Kepha kuthiwani nge- ikhwalithi?

Ngaphambi nje kokukhulelwa kweqanda njalo ngenyanga, amaqanda akho aqala ukuhlukana.

Amaqanda amadala athambekele kakhulu emaphutheni phakathi nale nqubo yokuhlukanisa, okwenza kube lula ukuthi aqukethe ama-chromosomes angajwayelekile. Kungakho amathuba okuba nengane ene-Down syndrome nokunye ukuthuthuka kokukhula akhule njengoba ukhula.

Ungacabanga ngesilondolozi sakho samaqanda njengebutho elincane. Amasosha anamandla asezingeni eliphambili. Njengoba iminyaka ihamba, amaqanda akho avulwa noma alahlwe, futhi amadala, asezingeni eliphansi ahlala.

Kwenzekani ngamaqanda akho esikhathini sokuya esikhathini?

Lapho uphelelwa ukunikezwa kwakho kwamaqanda asebenzayo, ama-ovari akho azophela ukwenza i-estrogen, futhi uzodlula esikhathini sokuya esikhathini. Ngokuqondile lapho lokhu kwenzeka kuye ngenani lamaqanda owazalwa unawo.

Uyakhumbula ukuthi umehluko phakathi kwesigidi esisodwa noma ezimbili? Uma uzalwe unenani elikhudlwana lamaqanda, ungaba phakathi kwabesifazane abakwaziyo ukuba nezingane zemvelo ngokwemvelo phakathi kweminyaka yabo yobudala ephakathi noma engamashumi amane.

Okuhlobene: Ukuba nengane ku-50

Ukuthatha

Ingabe unenkinga yokukhulelwa? Manje njengoba usunezinombolo, uzokwazi kangcono ukuxoxa ngezinketho zakho ne-OB yakho.

Uma ukhathazekile ukuthi isikhathi asikho ngasohlangothini lwakho, umzila owodwa ongacabanga ngawo ukuqandisa amaqanda akho, i-oocyte vitrification noma i-elective preservation preservation (EFP).

Abesifazane abaningi ababheka i-EFP bashukunyiswa ukuthayishwa kwewashi labo lemvelo. Abanye kungenzeka ukuthi sebeqala ukwelashwa ngamakhemikhali okungathinta ukuzala kwabo. (Qaphela: Ukuqanda kweqanda ngaphambi kwe-chemo akubhekwa njengokukhetha, njengoba kukhonjiswa ekulondolozweni kokuzala.)

Ucabanga nge-EFP? Ngokomthombo owodwa, amathuba akho okuba nengane enamaqanda akho afriziwe angcono uma ufriza ungakabi neminyaka engama-35.

Obunye ubuchwepheshe bokuzala, obufana ne-in vitro fertilization, buvumela nabesifazane abaseminyakeni yama-40s - ngisho nama-50s - ukuthi bazuze ukukhulelwa.

Uyacelwa ukuthi uqaphele ukuthi i-IVF enamaqanda akho mancane amathuba okuthi ibe yindlela efanelekayo yowesifazane ongenanzalo osedlule eminyakeni engamashumi amane. Kodwa-ke, amaqanda abanikeli avela kwabesifazane abasebancane angavumela abesifazane abakwiminyaka yama-40s nengama-50 ukuba bakhulelwe.

Khuluma nodokotela wakho kusenesikhathi futhi kaningi ngamasu wokuzala nokuthi ukuzala kungashintsha kanjani ngokuhamba kwesikhathi. Yazi ukuthi unezinketho.
