Kukhona izikhathi eziningana lapho owesifazane ngamunye ebhekene nezinguquko emlandweni we-hormonal emzimbeni. Izinguquko ze-hormone yobudala ezimweni eziningi zenzeka kubesifazane abasha futhi eneminyaka engaba ngu-50.
Izinguquko ze-hormonal ezinganeni
Ngesikhathi sokukhulelwa kwentombazane (isikhathi sokuqala), ama-ovaries akhiqiza njalo inani elithile le-estrogen (okuthiwa i-hormone yesifazane). Ukuthuthukiswa kwayo kulawulwa yingxenye yobuchopho - i-hypothalamus, ngokwemigomo ye "impendulo", ngaleyo ndlela igcina ukuhlushwa kwe-hormone ezingeni eliqinile.
Ukuqala kokukhulelwa kwenzeka kuzo zonke izintombi ngesikhathi esisodwa. Kuncike ezintweni ezihlukahlukene, ngezindlela eziningi ngesici sofuzo, okungukuthi, ngesikhathi lapho lesi sikhathi sasiqala kubazali.
Ngesikhathi sokuqala kokukhulelwa, inani le-estrogen elikhiqizwayo landa kakhulu. I-hypothalamus, njengokungathi, iguqula "izilungiselelo" zayo futhi "ivumela" ukuhlushwa okuphakeme kwe-estrogen egazini. Le nqubo ivame ukuhambisana nokwanda kwesisindo somzimba.
Ngenxa yezinga eliphezulu le-estrogen ne-progesterone (ehlanganiswa ngama-ovari emva kokuvuthwa) egazini, izinguquko ezihlukahlukene zomzimba zenzeka emzimbeni.
Ukusetshenziswa kwama-hormone kufana kakhulu nomzimba wamanoni omzimba. Ngakho-ke, ngokuvamile emantombazaneni, okuqukethwe kwamanoni emzimbeni okuphansi, kungenzeka ukulibazise ukubonakala kwesikhathi sokukhulelwa.
Amantombazane nawo akhiqiza ama-hormone afana no-testosterone ne-androgens, kodwa ukuhlushwa kwabo kuphansi. Zithinta izinguquko zomzimba emzimbeni, isibonelo, ngokugqugquzela ukukhula kwezinwele zomzimba.
Ngenxa yezinga eliphezulu lama-hormone emzimbeni ngesikhathi sokukhulelwa, amantombazane angathola ukungazinzi ngokomzwelo, ukushintsha kwemizwelo ebuhlungu, imizwa yokukhathazeka.
Izinguquko ze-Hormonal kwabesifazane
Njengoba kukhulunywe ngenhla, isikhathi sesibili soshintsho lwe-hormonal siqala cishe eminyakeni engama-50, sithinta kakhulu isimo semizwa, esingenakuthinta ubuhlobo bomndeni. Ngokujwayelekile phakathi nalesi sikhathi isikhathi ubuhlobo buhlolwe amandla.
Eminyakeni embalwa ngaphambi kokuqala kokuya esikhathini, ungabona ukwehla kwezinga lamahomoni akhiqizwa ama-ovari. Kunezintambo ezimbalwa futhi ezincane eziqukethe amaqanda, futhi lapho kufika ukuyeka komzimba ziyabonakala ngokuphelele. Lokhu kuholela eqinisweni lokuthi i-progesterone ne-estrogen yeka ukukhiqizwa, akukho umzimba ophuzi nokuya esikhathini kuphele. Njengomthetho, le nqubo iyenzeka kwabesifazane esikhathini esiphakathi kweminyaka engu-48 kuya kweyengu-52.
Izimpawu ezibonakalayo kakhulu zenguquko emalini ye-hormonal ngalesi sikhathi yilezi:
- Ukungenakwenzeka kokukhulelwa, njengoba, njengoba kuphawuliwe ngenhla, ama-follicles aqukethe iqanda ayanyamalala.
- Ukunciphisa isifiso socansi. Njengomthetho, lokhu kubangelwa ukuthi ukungalingani kwe-hormonal kuholela ekomeni esiswini futhi kungakhululekile ngesikhathi sokulala ngokocansi. Futhi, ukukhangwa kungase kwehle ngenxa yokuziphendulela, ngoba umngane wezinguquko ze-hormone ngokuvamile ukungazinzi ngokomzwelo, okuholela ekudakaleni ebuhlotsheni nomlingani. Ukushisa kungabangelwa ukwehla kwesilinganiso se-estrogen esenziwe, okwenza izindonga zangasese zingeneke kancane. Amafomu ama-labi amakhulu ashintsha isimo, abe mncane. Konke lokhu kunomthelela ekunciphiseni emsebenzini wezocansi
- Ngokuphathelene nokwehla kwezinga lamahomoni, izinga lesifiso socansi liyehla, nakuba i-testosterone, okuyinto engxenyeni eyinhloko yesifiso sobulili, iyaqhubeka ikhiqizwa kuma-ovari. Nokho, naphezu kwalokhu, ucwaningo lwamuva luveze ukuthi abesifazane abanomlingani ohlala njalo bangakwazi ukugcina ubulili obufanayo kanye nomsebenzi njengangaphambili. Ngaphezu kwalokho, cishe amaphesenti angamashumi amane alaba besifazane ahlolisise ukuthi ngokuvimbela nokwelashwa okufanelekile, umsebenzi wabo wocansi ngalesi sikhathi uthuthuke kakhulu futhi ikuvumela ukuba uthole injabulo eyengeziwe emisebenzini yocansi.
