Yonke intombazana iyazi ukuba into efana nokuya esikhathini iya kuhamba nayo kude kube yinkomo. Amantombazana amancinci, ekuqale ahlangabezane nokuphuma kwinqanaba lomzimba, awuqondi isizathu sokuba kutheni le nto yenzeka. Kodwa yonke into ilula: ngaba amadoda axelela intombazana ukuba akukho khulelwa kwaye unokwenza inxalenye yecala elincinci le-endometrium (intsimbi yangaphakathi yesisu), ekhula ukwenzela ukuba uqale ukukhula kombindi womntu, kodwa ngoku kwakungekho mfuneko. Nangona kunjalo, ezona nxu lumano zenzeke phakathi komjikelezo, ukusuka ekuphumeni kwexesha ukuya kwabanye. Ngeli xesha, kukho i-ovulation, ebonisa ngokucacileyo into efana nokukhululwa kweqanda elivuthiweyo, elilungele ukuzalisa.
I-ovulation kwenzeka njani?
Wonke umntu uyazi ukuba ibhinqa linamaqanda amabini, apho, njengommiselo, ngomnye, kunye nexesha elilodwa kwenyanga, iivuno zivuthwa. Ngokuqala kwimijikelezo nganye yokuya esikhathini, le ndlela ivuselelwa ngokuphindaphindiweyo, kwaye oku kuya kwenzeka ngelixa ilungu elifanelekileyo lezesondo linesiqalo. I-follicle, okanye "capsule", apho iqanda likhula khona, liqhakazile kwaye likhuphe iqanda kwiibhulo zomzimba ngexesha 'lokuzalwa kwayo.' Le ngqungquthela ibizwa ngokuba lixesha lokuvuthisa okanye ngexesha lemini, eliya kuchaneka ngakumbi, kuba ukukhululwa kweqanda kwi "capsule" kwenzeka phakathi kwemizuzu engama-2-3, kwaye uhlala ngaphandle kwamahora angama-24.
Indlela yokugqiba umhla wokuvuthwa?
Umjikelezo wesisithi somfazi uqukethe izigaba ezibini: ulandelelwano lobuchule kunye nolulwimi. Eyokuqala inoxanduva lokutshatyalaliswa kweqanda, kwaye okwesibini ibangela uxanduva lokukhulelwa nokukhulelwa kokukhulelwa. Ekupheleni kwesigaba sobugqwetha, kukho into enjalo njenge-ovulation, into yokuba iqanda "lizalwe" xa lishiya ulandelelwano kwaye lingena kwiphubhu ye-fallopian, apho, mhlawumbi, ukukhulelwa kuza kwenzeka.
Bala esi siganeko esibalulekileyo, okanye umhla ovulation ulula, into ebaluleke kakhulu kukuba iinyanga zamadoda eziqhelekileyo ziqhelekileyo. Ngokomzekelo, thabatha umjikelezo weentsuku ezingama-30. Isigaba sesibini, njengokulawula, sihlala sihlala iintsuku ezili-14, kungakhathaliseki ukuba sisiphi ixesha. Ngako oko, umhla wokugqithisa awuyi kuba nzima ukubala: 30 - 14 = 16. Ngoko ke, ukuvuthwa kwe-ovulation kuya kwenzeka kwiintsuku ezili-16 ukususela ekuqaleni kwexesha.
Nangona kunjalo, le ndlela ayisebenzisi kubasetyhini abanemijikelezo engavumelekanga. Ukongezelela, i-ovulation ingabikho kokuqala nakwexesha elide, elingahambelani nezibalo zethu.
Ngoko ke, ukuba awuqinisekanga ngokupheleleyo indlela yokubala yeemathematika, unokubhenela kwezinye ezimbini. Kwiimeko zokuqala, uvavanyo lwe-ovulation luza kuhlangulwa, olunokuthengwa nakweyiphi na ikhempiki.
Okwesibini kusekelwe ekucwangciseni igrafu yeqondo lokushisa. Ngenxa yoko, ukuya kwinyanga kufuneka kuqala ngokukhaphama, ngaphandle kokuphuma ebhedeni, ukulinganisa ukushisa okusemgangathweni. Kufuneka kuqatshelwe ukuba ukulala okuqhubekayo ngaphambi kokuba umlinganiselo kufuneka ube ubuncinane ubuncinane iiyure ezingama-6. Ngomhla xa i-ovulation ivela, kwitshathi uza kuphawula ukushisa okuthe gqolo phezulu (ubuncinane nge-0.3 degrees).
Ngoko, ngokwemiqathango elula, i-ovulation, kokubili kubasetyhini kunye namantombazana - yinto enjalo enokuqinisekisa ukuqala kokukhulelwa kwi-70% yamatyala ukuba ukuziphatha ngokwesondo okungaxhatshazwayo kwenzelwa ngeli xesha.
I-Ovulation kukukhululwa kwe-ovule kwi-follicle, kwaye umbane walo mcimbi uyafana namantombazana amantombazana kunye nabafazi abavuthiweyo. Le nto ayinayo imingcele yeminyaka kwaye iyenzeka ngexesha elide xa ubulili obufanelekileyo buhamba rhoqo ngenyanga.
