Kodi mapangidwe a ziwalo zolimbitsa thupi zimapangidwa motani?
Pogwiritsa ntchito ziphunzitso zapatogogeni pali kuphwanya njira yothetsera ziwalo zogonana pachigawo cha embryogenesis. Kotero, mwachitsanzo, ma vaginas awiri amapangidwa chifukwa cha kusakanikirana kosakwanira kwa njira ngati Muller channels.
Monga lamulo, madokotala amapeza zovuta kupereka yankho losavuta ku funso la zifukwa za kuphwanya koteroko. Komabe, pafupifupi pafupifupi 100%, zitha kunenedwa kuti chitukuko cha mtundu uwu wachisokonezo chimatsogoleredwa ndi:
- kuthandizira mwana wamtsogolo wa zoopsa zachilengedwe;
- Matenda a tizilombo (rubella, fuluwenza, toxoplasmosis pa nthawi ya mimba);
- mankhwala osokoneza bongo kumaliseche oyambirira (masabata 8-16).
Ndi mitundu yanji yowonjezera maanja?
Choncho, kaŵirikaŵiri pakati pa zolakwika zofanana m'mabanja a amayi amalembedwa kawiri kawiri ka chiberekero ndi chiberekero (chiberekero chachiwiri ndi vaginas awiri). Zikatero, pamene wodwala akufufuzidwa, dokotala amapeza chiberekero chokhachokhachokha, chomwe chimakhala ndi 1 chigoba chachikulu ndi 1 ovary. Pachifukwa ichi, kupezeka kwa makosi awiri a uterine ndi 2 vaginas zinalembedwa. Nthawi zina, chiberekero ndi ma vaginas onse amatha kupatulidwa ndi chikhodzodzo kapena chikhodzodzo, ndipo nthawi zina zimagwirizana. Kawirikawiri, magawo onse awiri a vaginomu ali osagwirizana komanso amatha kumaliza, Nthawi zambiri chimodzi mwa izo chimakula bwino.
Mchitidwe wachiwiri wa matendawa ndi kuphatikiza kwa chiberekero, ndi umaliseche umodzi wokha (bicorne, chiberekero chofanana ndi chiwalo, intrauterine septum).
Monga lamulo, kuphatikiza kwa chiberekero ndi umaliseche kumaphatikizidwa ndi ziphuphu zina za dongosolo la genitourinary. Kotero, mwachitsanzo, mukamaphatikiza chiberekero ndi kupatsa pang'ono kwa vaginas mmodzi, nthawi zambiri amatsitsimutsa impso. Komanso nthawi zambiri odwala omwe ali ndi vagina awiri amakhala ndi aresia.
Kodi matendawa akupezeka bwanji?
Kukhalapo kwa vaginas awiri osiyana mwa msungwana sangathe kuyambitsa mawonetseredwe a chipatala. Choncho, kawirikawiri odwala oterewa amadziwa zochitika zawo za ziwalo zoberekera, apeze akapita kukaonana ndi azimayi.
Komabe, ndi chidziwitso chokwanira cha chiberekero ndi chiberekero, chomwe chikuphatikizidwa ndi atresia wa m'mimba imodzi yamaliseche, zizindikiro zimatha kuoneka patatha miyezi 3-6 kuchokera kumsambo. Pa nthawi yomweyi, msungwana wina akudandaula za ululu wolimba, wam'mimba m'mimba, yomwe, atatha kumwa mankhwala osokoneza bongo, samachoka.
Pazochitikazi ngati pali ndondomeko yowonongeka m'masewu osakanikirana, pangakhale phokoso la magazi kumaliseche. Pankhaniyi, msungwanayo nthawi zambiri amawonetsa maonekedwe a mwazi wamagazi, osati okhudzana ndi kusamba, omwe amakhala ndi khalidwe loyera.
Kodi ma vaginas awiri amapezeka kangati?
Ndikoyenera kuzindikira kuti kuperewera kotereku sikungalembedwe. Ndicho chifukwa chake amayi ambiri samakhulupirira mawu ngati amenewa, ndipo nthawi zambiri amafunsa madokotala ngati amayi awiri ali ndi vaginas.
Kuphwanya koteroko kumachitika. Mwachitsanzo, Hazel Jones anapeza vaginas awiri okha ali ndi zaka 18. Asanayambe kupita kwa dokotala, sanakayikire ngakhale pang'ono. Pachifukwa ichi, gawo loyamba la izi linazindikiridwa ndi chibwenzi cha mtsikanayo, yemwe anamuuza kuti ali ndi "cholakwika", monga momwe ziyenera kukhalira.
