Kukho ixesha elininzi apho umfazi ngamnye ejongene nenguqu kwimimandla ye-hormonal emzimbeni. Ukutshintsha kwexesha lomda kwiimeko ezininzi kuvela kubasetyhini abaselula kunye nangeminyaka engama-50 ubudala.
Iinguqu zeHormon kwiintsholongwane
Ngexesha lentombazana yobushushu (ixesha eliphambi kwexesha eliphambili), ii-ovari zihlala zivelisa inani elithile le-estrogen (okubizwa ngokuba yi-hormone yesini). Uphuhliso lwayo lulawulwa yinxalenye yengqondo - i-hypothalamus, ngokwemigaqo "yengxelo", ngaloo ndlela igcina ukuxinwa kwehommone kwinqanaba elincinci.
Ukuqala kobuntwaba kwenzeka kwiintombazana ngexesha ngalinye. Kuxhomekeke kwimibandela eyahlukeneyo, kwiintlobo ezininzi kwi-genetic factor, oko kukuthi, ngelixesha eli xesha laqala ngayo kubazali.
Ngethuba lokuqala kokushatshulwa, ixabiso le-estrogen eveliswayo landa kakhulu. I-hypothalamus, njengokuba kunjalo, iguqula "izicwangciso" zayo kwaye "ivumela" uxinzelelo oluphezulu lwe-estrogen egazini. Le nkqubo idla ngokudibanisa nokunyuka kwesisindo somzimba.
Ngenxa yesigaba esiphakamileyo se-estrogen kunye neprogesterone (ehlanganiswa ngama-ovari emva kokuvuthwa kwegazi) egazini, utshintsho oluthile lomzimba luvela emzimbeni.
Ukuhlanganiswa kwama-hormone kuhambelana kakhulu nomlinganiselo weoli. Ngenxa yoko, ngokuqhelekileyo kumantombazana, umxholo weoli ophantsi kwimeko ephantsi, kunokwenzeka ukulibazisa ukubonakala kwexesha lokukhulelwa.
Amantombazana avelisa ama-hormone afana ne-testosterone kunye ne-androgens, kodwa i-concentration yabo iphantsi. Zichaphazela utshintsho lomzimba kumzimba, umzekelo, ngokukhuthaza ukukhula kweenwele zomzimba.
Ngenxa yezinga eliphezulu lama-hormone emzimbeni ngexesha lokukhulelwa, amantombazana anokufumana ukungazinzi ngokomzwelo, ukuguquka kwemizwelo eguqukayo rhoqo, iimvakalelo zokuxhalabisa.
Utshintsho lweHormon ku bafazi
Njengoko kuchazwe ngasentla, ixesha lesibini leenguqulelo ze-hormones liqala malunga neminyaka engama-50, elichaphazela kakhulu imida yeemvakalelo, ezingenakuchaphazela ulwalamano lwentsapho. Ngokuqhelekileyo ngeli xesha lexesha ubuhlobo buvavanywa ngamandla.
Iminyaka embalwa ngaphambi kokuqala kokuphuma kwesisu, ungabona ukuhla kwezinga lama hormone eziveliswa ngama-ovari. Kukho izintlu ezimbalwa kunye nezimbalwa ezincinci eziqule iqanda, kwaye ngokuza kwexesha lokuphela komzimba ziyabhubha ngokupheleleyo. Oku kubangela ukuba i-progesterone ne-estrogen iphelile ukuveliswa, akukho mzimbeni ophuzi kunye nokuya esikhathini. Njengomthetho, le nkqubo iqhutyelwa kwabasetyhini kwixesha eliphakathi kweminyaka engama-48 ukuya kuma-52.
Iimpawu ezibonakalayo zeenguqu kwi-balance hormonal ngeli xesha zi:
- Ukungenakwenzeka kokukhulelwa, njengoko, njengoko kuphawuliwe ngasentla, iifollicle eziqule iqanda zanyamalala.
- Ukunciphisa umnqweno wesondo. Njengomthetho, oku kubangelwa ukuba ukungalingani kwe-hormonal kukhokelela ekumekeni kwisini kunye nokuphazamiseka ngexesha lokwabelana ngesondo. Kwakhona, ukukhangwa kunganciphisa ngenxa yokuzithemba, ngenxa yokuba utshintsho lwama-hormone ludla ngokungazinzi ngokomzwelo, olukhokelela ekudakaleni kobudlelwane kunye nomlingane. Ukucwina kungabangelwa ukuhla kwexabiso le-estrogen eyenziwe, okwenza iindonga zelinye iinduli zingancinci. Izakhiwo ezinkulu zebibi zitshintsha ukuma, zibe zincinci. Konke oku kuncedisa ekunciphiseni kwintsebenzo yesondo
- Ngokubhekiselele ekunciphiseni kwinqanaba lama-hormone, isantya sesifiso sesini sinciphisa, nangona i-testosterone, eyona nto iphambili yenkanuko yesondo, iyaqhubeka iveliswa kuma-ovari. Nangona kunjalo, nangona kunjalo, uphando olutshanje luye lwabonisa ukuba abafazi abanomlingani osisigxina banokugcina isondo esifanayo kunye nomsebenzi njengangaphambili. Ngaphezu koko, malunga neepesenti ezingama-40 zabesetyhini bahlolisisa ukuba ngokukhusela kunye nokunyangwa okufanelekileyo, umsebenzi wabo wesondo ngeli xesha liphuculwe kakhulu kwaye ikuvumela ukuba ufumane ngakumbi uvuyo kwimisebenzi yesondo.
