Ambiri aife timayenderana bwino ndi matupi athu. Mwachitsanzo, mwina nthawi yomweyo mumaloza kumalo olimbawo paphewa lanu lamanja omwe amadzimangirira mukakhala ndi nkhawa.

Komabe, mungakonde kudziwa zambiri za zomwe zikuchitika mkati mwa thupi lanu, monga, "Kodi nkhani ya mazira anga ndi yotani?"

Kodi ana achikazi amabadwa ndi mazira?

Inde, makanda achikazi amabadwa ali ndi timaselo tonse tomwe azikhala nako. Ayi maselo atsopano a dzira amapangidwa m'moyo wanu.

Izi zakhala zikuvomerezedwa kale kuti ndizowona, komabe katswiri wazabodza wobereka John Tilly adapereka kafukufuku mu 2004 yemwe poyambirira adanenedwa kuti awonetse maselo am'mimba atsopano mu mbewa.

Chiphunzitsochi chatsutsidwa ndi gulu lonse la asayansi, komabe pali kagulu kakang'ono ka ofufuza omwe akutsata ntchitoyi. (Nkhani ya 2020 mu The Scientist ikufotokoza zokambirana.)

FYI: Kutanthauzira mawu kwa mazira

Dzira losakhwima limatchedwa oocyte. Oocyte amapumuliramo Mapulogalamu onse pa intaneti (matumba odzaza madzi omwe amakhala ndi dzira losakhwima) m'mazira anu mpaka atayamba kukhwima.

Oocyte imakula ndikukhala ootid ndikukula kukhala dzira (zambiri: ova), kapena dzira lokhwima. Popeza iyi siyi maphunziro a sayansi, makamaka tidzamamatira ku mawu omwe timawadziwa bwino - dzira.

Kodi anthu amabadwa ndi mazira angati?

Monga mwana wakhanda kumayambiriro kwa chitukuko, mkazi amakhala ndi mazira 6 miliyoni.

Chiwerengero cha mazira awa (ma oocytes, kunena molondola) amachepetsedwa pang'onopang'ono kuti mwana wamkazi akabadwa, ali ndi mazira pakati pa 1 ndi 2 miliyoni. (Magwero amasiyana pang'ono, koma mosasamala kanthu, tikulankhula za a manambala asanu ndi awiri chithunzi!)

Nanga n’chifukwa chiyani msambo umayamba pobadwa?

Funso labwino. Mazira alipo, ndiye nchiyani chikuimitsa msambo kuyamba?

Kusamba kumatha mpaka mtsikana atha msinkhu. Kutha msinkhu kumayamba pamene hypothalamus muubongo imayamba kutulutsa mahomoni otulutsa gonadotropin (GnRH).

Komanso, GnRH imalimbikitsa chithokomiro kuti chikhale ndi hormone yolimbikitsa (FSH). FSH imayambitsa kukula kwa dzira ndipo imayambitsa kuchuluka kwa estrogen.

Ndi zonsezi zikuchitika mkati mwathu, nzosadabwitsa kuti enafe timakumana ndikusintha kwamalingaliro!

Mukuganiza za chizindikiro choyamba cha kutha msinkhu? Msambo umayamba patadutsa zaka ziwiri kuchokera pamene bere laphuka - kanyama kakang'ono kameneka kamayamba kukhala m'mawere - kamawonekera. Ngakhale ausinkhu wazaka 12, ena amatha kuyamba zaka 8, ndipo ambiri amayamba ali ndi zaka 15.

Mtsikana amakhala ndi mazira angati akatha msinkhu?

Mtsikana akatha msinkhu, amakhala ndi mazira pakati pa 300,000 ndi 400,000. Hei, nanga bwanji mazira ena onsewo? Nayi yankho: Asanakwane msinkhu, oposa 10,000 amafa mwezi uliwonse.

Kodi mayi amataya mazira angati mwezi watha msinkhu?

Nkhani yabwino ndiyakuti kuchuluka kwa mazira omwe amafa mwezi uliwonse kumachepa atatha msinkhu.

Atayamba kusamba, mayi amataya mazira pafupifupi 1,000 (osakhwima) mwezi uliwonse, malinga ndi Dr. Sherman Silber, yemwe adalemba "Beating Your Biological Clock," chitsogozo cha odwala kuchipatala chake osabereka. Ndipafupifupi 30 mpaka 35 patsiku.

Asayansi sakudziwa chomwe chimalimbikitsa izi kuti zichitike, koma amadziwa kuti sizimakhudzidwa ndi zinthu zambiri zomwe tingathe kuwongolera. Sichikukhudzidwa ndi mahomoni anu, mapiritsi oletsa kubereka, kutenga mimba, zowonjezera zakudya, thanzi, kapena ngakhale kudya chokoleti.

Zina kupatula: Kusuta kumathandizira kuchepa kwa dzira. Ma chemotherapies ena ndi radiation imathandizanso.

Ma follicles akakhwima, amayamba kuzindikira mahomoni am'masamba anu amwezi. Komabe, si onse opambana. Dzira limodzi lokha limatulutsa dzira. (Kawirikawiri, osachepera. Pali zosiyana, zomwe nthawi zina zimayambitsa mapasa a abale.)

Mkazi ali ndi mazira angati azaka za m'ma 30?

Popeza manambala, mkazi akafika zaka 32, kubereka kwake kumayamba kuchepa ndikuchepa mwachangu pambuyo pa 37. Pofika zaka 40, ngati ali ngati ambiri aife, amakhala atatsala pang'ono kupereka mazira ake asanabadwe .

Zokhudzana: Zomwe muyenera kudziwa mu 20s, 30s, ndi 40s za kutenga pakati

Mkazi amakhala ndi mazira angati pa 40?

Chifukwa chake mwagunda 40. Palibe yofanana-yankho poyankha kuti mwasiya mazira angati. Kuphatikiza apo, zinthu zina - monga kusuta - zitha kutanthauza kuti muli ndi ochepera kuposa mkazi wina.

Kafukufuku wasonyeza kuti mkazi wamba amakhala ndi mwayi wochepera 5% wokhala ndi pakati nthawi iliyonse. Avereji ya zaka zakusamba ndi 52.

Dulani manambala ndipo muwona kuti pakangotsala mazira 25,000 m'mazira (pafupifupi zaka 37), mumakhala ndi zaka pafupifupi 15 mpaka mutha kusamba, pafupifupi. Ena adzafika kumapeto kwa msambo, ndipo ena adzawagunda pambuyo pake.

Zokhudzana: Zomwe muyenera kudziwa pakubala mwana ali ndi zaka 40

Chifukwa chiyani dzira limachepa tikamakalamba?

Takambirana zambiri za kuchuluka mazira omwe muli nawo. Nanga bwanji za khalidwe?

Kutatsala pang'ono kutulutsa dzira mwezi uliwonse, mazira anu amayamba kugawikana.

Mazira achikulire amakhala ndi zolakwika nthawi yogawikana, zomwe zimapangitsa kuti azikhala ndi ma chromosomes osazolowereka. Ichi ndichifukwa chake mwayi wokhala ndi mwana yemwe ali ndi matenda a Down syndrome ndi zina zomwe zingakule bwino mukukula mukamakula.

Mutha kuganiza za malo anu osungira dzira ngati gulu lankhondo laling'ono. Asitikali olimba mtima ali kutsogolo. Pakapita zaka, mazira anu amatayidwa kapena kutayidwa, ndipo achikulire, otsika amakhalabe.

Kodi chikuchitika ndi mazira anu pa nthawi ya kusamba?

Mukatha kupezeka ndi mazira othandiza, mazira anu amasiya kupanga estrogen, ndipo mudzadutsa kumapeto. Izi zikachitika zimadalira kuchuluka kwa mazira omwe mudabadwa nawo.

Kumbukirani kuti pali kusiyana pakati pa 1 kapena 2 miliyoni? Ngati munabadwa ndi mazira ochulukirapo, mutha kukhala m'modzi mwa azimayi omwe amatha kukhala ndi ana mwachilengedwe mpaka azaka zapakati kapena makumi anayi.

Zokhudzana: Kukhala ndi mwana pa 50

Kutenga

Kodi mukuvutika kutenga mimba? Tsopano popeza muli ndi manambala, mudzakhala okonzeka bwino kukambirana zomwe mungachite ndi OB wanu.

Ngati mukuda nkhawa kuti nthawi siili pambali panu, njira imodzi yomwe mungaganizire ndikuwumitsa mazira anu, aka oocyte vitrification kapena kuteteza chonde (EFP).

Amayi ambiri omwe amalingalira za EFP amalimbikitsidwa ndi kukokota kwanthawi yawo yachilengedwe. Ena atha kuyamba mankhwala a chemotherapy omwe angakhudze chonde. (Dziwani: Dzira lozizira kwambiri chemo isanatchulidwe kuti "yosankhidwa," monga momwe amawonetsera kusungidwa kwa chonde.)

Poganizira EFP? Malinga ndi buku lina, mwayi wanu wokhala ndi mwana ndi mazira anu oundana ndibwino ngati muzizira musanakwanitse zaka 35.

Matekinoloje ena oberekera, monga mu vitro feteleza, amalolanso azimayi azaka zapakati pa 40 - ngakhale 50s - kuti akhale ndi pakati.

Chonde dziwani kuti IVF yokhala ndi mazira anu sangakhale njira yothandiza kwa mayi wosabereka yemwe adatha zaka 40. Komabe, mazira opereka kuchokera kwa azimayi achichepere amatha kuloleza amayi azaka za 40 ndi 50 kuti akhale ndi pakati.

Lankhulani ndi dokotala koyambirira komanso pafupipafupi za njira zakuberekera komanso momwe chonde chingasinthire pakapita nthawi. Dziwani kuti muli ndi zosankha.
