Yintoni i-follicle evuselelayo? Kukuchaphazela njani ukusebenza komzimba?

Ngaba uqhelene ne-follicle evuselelayo yehomoni (FSH)? Yihomoni enxulumene nokuzala. Amanqanaba ayo ahluka kwiimeko ezinje: iingxaki zokuzala, imeko yokukhulelwa okanye ukuba phantsi konyango lwehomoni, phakathi kwabanye.

Kweli nqaku siza kubona yonke into malunga nale hormone: yeyiphi imisebenzi yayo, iveliswa phi, athini amanqanaba "aqhelekileyo" kumanqanaba ahlukeneyo omjikelo wokuya exesheni, athetha ntoni amanqanaba angaqhelekanga (zombini asezantsi aphezulu) yona kwaye Okokugqibela, yintoni follicle evuselelayo yovavanyo lwehomoni okanye uviwo luqukethe?

Ifollicle Ukukhuthaza iHormone (FSH)

I-follicle-evuselela i-hormone, ekwabizwa ngokuba yi-follicle-stimulating hormone okanye i-follicle-stimulating hormone (FSH), luhlobo lwehomoni ye-gonadotropin. Le hormone ifunyanwa ebantwini nakwezinye izilwanyana ezincancisayo.

Umsebenzi wawo ubalulekile kumjikelezo wokuzala, kwaye uthatha inxaxheba kuzo zombini izini ekukhuleni nasekukhuleni.

I-hormone evuselela i-follicle iveliswa kwi-pituitary; I-pituitary gland, ekwabizwa ngokuba yi "pituitary gland," yincindi encinci ebekwe ngezantsi nje kwengqondo evelisa iihomoni ezahlukeneyo, ezihamba ziye egazini kwaye zenze imisebenzi yazo.

Imisebenzi emzimbeni

Inayiphi indima le hormone inamadoda nabasetyhini? Kwimeko yamadoda, i-follicle evuselelayo yehomoni iyabandakanyeka kulwakhiwo lwesidoda. Kwabasetyhini, umsebenzi wayo unxulumene nommiselo wokuvuthwa komzimba kude kube kwinqanaba lokufikisa. Ukongeza, kule ngqiqo, yihomoni ephetheyo yokukhuthaza ukuhlanganiswa kwe-estrogens.

Kwelinye icala, kwinqanaba lokuqala lokuya exesheni komfazi, I-follicle evuselelayo yehomoni imodareyitha ukukhula kwe-oocyte. I-Oocyte ziiseli zentsholongwane yabasetyhini; Oko kukuthi, ziiseli ezikwinqanaba eliphambi kwelee-ovules ezivuthiweyo (ezifikelela ekubeni zezi).

Ukongeza, i-follicle evuselelayo yehomoni sisiphawuli esivumela ukuxilonga izitenxo ezithile kumanina, ngokunxulumene nokungachumi kunye nokuya exesheni (umthetho).

Yiyo loo nto ihomoni edibene ngokusondeleyo nokuzala, kokubini emadodeni nakwabasetyhini. Amanqanaba abo, njengoko siza kubona kamva, asivumela ukuba siqwalasele ukuba amalungu ezesondo asebenza kakuhle, okanye ukuba ngaba kukho ingxaki (ngamanqanaba angaqhelekanga).

Amanqanaba

Amanqanaba e-follicle evuselela i-hormone ayahluka ebomini. Ukufumana umbono ngokubanzi, ngaphambi kokufikisa, amanqanaba akho asusela kwi-0 ukuya kwi-0,4 yeeyunithi ze-FSH kwilitha nganye yegazi.

Njengoko sikhula kwaye nje ukuba singene kwinqanaba lokufikisa, amanqanaba alo ayenyuka ukuya kwiiyunithi eziyi-0.3 no-10 kwilitha nganye yegazi.

Umjikelo wokuya exesheni

Emva kwexesha, xa singena kwixesha lokuchuma, amanqanaba e-follicle evuselela i-hormone nawo ayatshintsha ngexesha lokuya exesheni. Ngexesha lokuya esikhathini, sifumana izigaba ezikhulu okanye amaxesha:

Ukuyeka ukuya exesheni

Ekugqibeleni, kwinqanaba lokuya exesheni, amanqanaba e-follicle-ekhuthaza i-hormone inyuka kakhulu, efikelela phakathi kweeyunithi ezingama-25 ukuya kwezili-135 kwilitha nganye yegazi.

Amanqanaba angaqhelekanga esi siyobisi

Kwenzeka ntoni xa amanqanaba ethu e-follicle evuselela i-hormone esiba yinto engaqhelekanga? Iimeko ezahlukeneyo zophendlo lwezifo zinokubangela oku, njengoku: ukubandezeleka ngenxa yeanorexia, ukutyeba kakhulu, ukungabikho kwe-ovulation, ukubandezeleka kwengxaki yethambo okanye i-hypothalamus, njl.

Kwelinye icala, kwimeko yokukhulelwa amanqanaba e-follicle evuselela i-hormone anokutshintsha ngokukhawuleza okanye angaqhelekanga.

1. Amanqanaba aphakamileyo

Amanqanaba aphakamileyo e-follicle evuselelayo yehomoni inokuba sisiseko seemeko ezithile ekufuneka zaziwe, kokubini emadodeni nakwabasetyhini.

1. 1. Kubafazi

Kwimeko yabasetyhini, amanqanaba aphezulu e-FSH anokubonisa: imeko yokuyeka ukuya exesheni okanye eye-postmenopausal (esele ikhankanyiwe), ukuya exesheni ngaphambi kwexesha, xa usiya kunyango lwehomoni, ukuba unesifo se-polycystic ovary syndrome, ukuba une-Turner Syndrome (ukuphazamiseka kwemfuza okuchaphazela ukukhula kwamantombazana, apho i-X chromosome ilahlekileyo, okanye ingaphelelanga), ukuba ngaba unalo naluphi na uhlobo lwethumba kwilungu lobufazi, njl.

1.2. Emadodeni

Emadodeni, amanqanaba aphezulu e-FSH anokubonisa: ukuthenwa, ukunxila, ukufumana ichemotherapy, ukwanda kwe testosterone, ukubandezeleka yiKlinefelter Syndrome, ukuthatha amayeza aqukethe i-testosterone, kunye nesizathu, njl.

2. Amanqanaba asezantsi

Kwelinye icala, amanqanaba asezantsi ehomoni kwabasetyhini abonisa a Ukungasebenzi kakuhle kwee-ovari xa kuveliswa amaqanda, ukukhulelwa, i-anorexia nervosa, ukuba kwiipilisi zokucwangcisa okanye i-corticosteroids, njl.

Kwelinye icala, emadodeni, amanqanaba asezantsi ehomoni abonisa ubukho bezi meko: ukunciphisa umsebenzi wepituitary (okanye i-hypothalamus), ukuba phantsi koxinzelelo, ukutyeba okanye ukuvelisa amadlozi ambalwa.

Uvavanyo lwefollicle olukhuthazayo

Kuqheleke kakhulu, ngakumbi phakathi kwabasetyhini, ukwenza uvavanyo lwehormone oluvuselelayo. Into eyenziwa lolu vavanyo kukulinganisa isixa esinaso sale hormone ngesampulu yegazi.

Isetyenziswa ikakhulu kuvavanyo lomsebenzi we-ovari ; Oku kuthetha ukuvavanywa kwenqanaba lokuchuma emfazini. Ngokwesiqhelo, uvavanyo lwehomoni olwenyusa ubumnandi lwenziwa kumaziko ancedisayo okuzala (nangona kungekuphela kwezi), apho abasetyhini ababonisa ubunzima (kunye neqabane labo, okanye hayi) abaya kukhulelwa.

Lusetyenziselwa ntoni uvavanyo lwe-FSH?

Sibonile ukuba luncedo kovavanyo lwe-FSH ekumiseleni iingxaki ezinokubakho zokuzala kwabasetyhini nakumadoda.

Ngokukodwa, uvavanyo lwehomoni olwenyusa ubumnandi lwenza ukuba kubonwe ukuba ingaba amalungu ezesondo, abesifazana nabesilisa (ama-ovari okanye amasende) asebenza ngokufanelekileyo, okanye ukuba kukho ingxaki ebangela ukuba kube nzima ukukhulelwa. Kwelinye icala, uvavanyo lukwavumela ukuba uqinisekise ukuba owasetyhini ukwinqanaba lokuya exesheni.

Ngaphandle kokwenziwa kumaziko okuncedisa ukuvelisa kwakhona, olu vavanyo lunokucelwa ngugqirha wezifo zabasetyhini okanye ugqirha wezonyango. Ke, ezinye iimeko ezivumela ukuvavanya olu vavanyo zezi:

Imilinganiselo

Xa uvavanyo lwehormone oluvuselelayo lusenziwa, amaxabiso esalathiso sabemi kuyaboniswana ngawo, ngokobudala kunye nesini lomntu kuthethwa ngaye. Isigaba somjikelo wokuya esikhathini okhoyo nawo uyathathelwa ingqalelo.
