Sonke sidlula esikhathini sokuthomba. Kungushintsho olukhulu empilweni yethu. Futhi uma sicabanga ngokuba nomntwana, uma sikhuluma ngemijikelezo yokuya esikhathini yabesifazane yanyanga zonke, uyazi ngomlawuli oyimfihlo ngemuva kwakho konke lokhu? Lowo mlawuli yi-hormone ebizwa ngokuthi i-GnRH. Nakuba leli gama lingase lixake kancane, lokhu kuyinto ebalulekile ekusebenzeni kohlelo lokuzala lwemizimba yethu. Namuhla, ake sixoxe ngokuthi iyini le hormone ye-GnRH nokuthi ibaluleke kangakanani emizimbeni yethu.
Ngakho-ke, iyini le GnRH?
Kalula nje, i-GnRH iyi-hormone ekhiqizwa yiwo wonke umuntu emizimbeni yakhe. Uma uqala ukuthomba usemncane, amazinga akho ale hormone ayanda. Lokhu kukhuthaza ukukhiqizwa kwamanye ama-hormone amabili abalulekile : i-Follicle-Stimulating Hormone (FSH) kanye ne-Luteinizing Hormone (LH) .
Lawa ma-hormone amabili, i-FSH ne-LH, abaluleke kakhulu empilweni yethu yokuzala. Abizwa ngokuthi ama-gonadotropin. Lawa ma-hormone anesibopho sokuvuthwa okufanele kwama-gonad ethu kanye nomsebenzi wawo. Kwabesifazane, lawa ma-gonad abizwa ngokuthi ama-ovari . Kwabesilisa, abizwa ngokuthi ama-testicles .
Amanye amagama e-GnRH
Udokotela wakho angasebenzisa amagama anjengalawa lapho ekhuluma ngale hormone:
- I-Luliberin
- I-hormone ekhipha i-luteinizing (LHRH)
Uyini umsebenzi we-GnRH emzimbeni wesifazane?
Esimiso sokuzala kwabesifazane, i-hormone i-GnRH ithinta ngokungaqondile ukukhiqizwa kwama-hormone i-estrogen ne -progesterone . Lawa ama-hormone ocansi ayinhloko kwabesifazane. Lawa ma-hormone abaluleke kakhulu ekuvuthweni nasekukhulelweni.
Nakhu okwenzekayo phakathi nomjikelezo wakho wokuya esikhathini wanyanga zonke:
- Umzimba wakho ukhipha uhlobo oluningi lwe-estrogen olubizwa ngokuthi i-estradiol, okwandisa ukukhiqizwa kwe-GnRH.
- Ngenxa yokwanda kwe-GnRH, i-hormone ye-FSH iyancipha kanti i-hormone ye-LH iyanda.
- Lezo zinguquko zibangela ukuthi iqanda likhishwe esibelethweni. Lokhu sikubiza ngokuthi i-ovulation .
Kwenzekani ku-GnRH emzimbeni wesilisa?
Esimiso sokuzala sabesilisa, i-hormone i-GnRH ikhuthaza kakhulu ukukhiqizwa kwezinhlobo ezimbili zama-hormone:
- I-Luteinizing hormone (LH): Lokhu kunquma ukuthi kukhiqizwa ama-hormone ocansi abesilisa abizwa ngokuthi i-testosterone kanye ne-androgens emzimbeni.
- I-Follicle-stimulating hormone (FSH): Lokhu kuthinta ukukhiqizwa kwesidoda.
Le hormone ye-GnRH ikhiqizwa kanjani emzimbeni?
Uhlelo lwe-endocrine lomzimba wethu lunesibopho sokukhiqiza i-GnRH. Cabanga nje, i-hormone ye-GnRH ikhiqizwa ama-neurons ku -hypothalamus ebuchosheni bethu bese ikhishwa iye egazini. Bese, le hormone ihamba egazini bese iya e-pituitary gland esisekelweni sobuchopho. Bese, i-pituitary gland ikhuthazwa ukukhiqiza ama-hormone e-FSH ne-LH esikhulume ngawo ngaphambilini bese iwakhipha aye egazini.
Kalula nje, i-GnRH ifana nomyalezo othunyelwe uvela ehhovisi elikhulu. Kungemva kokuthola lowo myalezo kuphela lapho amanye ama-hormone eqala ukusebenza khona.
Yiziphi izici ezithinta amazinga e-GnRH?
Amazinga e-GnRH avame ukuba phansi ngesikhathi sobuntwana. Ayanda ngesikhathi sokuthomba . Ngemva kwalokho, amazinga e-GnRH alawulwa ama-hormone ocansi (i-testosterone, i-estrogen, ne-progesterone) emizimbeni yethu. Kufana nohlelo lokuphendula. Lapho amazinga ama-hormone ocansi enyuka, umzimba unciphisa ukukhiqizwa kwe-GnRH. Lapho ama-hormone ocansi ehla, umzimba ukhulisa ukukhiqizwa kwe-GnRH. Kodwa kukhona okuhlukile kulokhu. Yilapho abesifazane bekhipha amaqanda. Ngaleso sikhathi, kokubili i-GnRH ne-estradiol kuyanda.
Kwenzekani uma amazinga e-GnRH enyuka?
Akuvamile kakhulu ukuthi i-GnRH ikhiqizwe ngokweqile. Uma amazinga ephezulu, kunengozi yokuthola izimila ezingengozini ezibizwa ngokuthi i-pituitary adenomas . Lezi zimila zingabangela ukuthi umzimba ukhiqize ama-hormone amaningi kakhulu i-FSH ne-LH. Ngenxa yalokho, amazinga e-estrogen noma e-testosterone emzimbeni angaba phezulu kakhulu. Uma amazinga e-GnRH ephezulu ezinganeni, kungenzeka isimo esibizwa ngokuthi ukuthomba kwangaphambi kwesikhathi .
Izinkinga ezenzekayo uma amazinga e-GnRH ehla
Amazinga aphansi e-GnRH angabangela izinkinga ezahlukahlukene kwabesifazane nabesilisa. Ake sibheke ukuthi ziyini.
| Izimo ezingase zenzeke kwabesifazane | Izimo ezingase zenzeke kwabesilisa |
|---|---|
| Ukuyeka kokuya esikhathini kwanyanga zonke okungajwayelekile noma okuphelele (i-Amenorrhea). | Ukuthomba okulibazisekile. |
| Ukuvuthwa. | Ukuncipha kwesifiso sobulili (i-Hypogonadism). |
| Ukuthomba okulibazisekile. | Ukungazali kwabesilisa, inani eliphansi lesidoda, noma ukungabikho kwesidoda (i-Azoospermia). |
| Ukungazali kwabesifazane. | Izifo zamasende ezifana ne-Kallman syndrome. |
| Ukuncipha kwesifiso sobulili (i-Hypogonadism). |
Alinganiswa kanjani amazinga e-GnRH?
Esikhundleni sokulinganisa i-GnRH ngqo, kuvame ukwenziwa ukukala amazinga ama-hormone i-FSH ne-LH ayivuselelayo. Lokhu kwenziwa ngokuhlolwa kwegazi okulula . Asikho isidingo sokuzila ukudla ngaphambi kwalokhu kuhlolwa. Kodwa-ke, kwabesifazane abasesikhathini, udokotela wakho angakucela ukuthi wenze lokhu kuhlolwa kwegazi ngosuku oluthile lomjikelezo wakho wokuya esikhathini.
Kwezinye izimo, kwenziwa ukuhlolwa kokukhuthazwa kwe-GnRH ukuze kutholakale ukuthi kunenkinga yini ngokukhiqizwa kwe-GnRH. Yilokhu okwenzekayo:
1. Okokuqala, udokotela wakho uzothatha isampula yegazi.
2. Ngemuva kwalokho, i-hormone ye-GnRH eyenziwe elebhu inikezwa wena njengomjovo noma nge-saline.
3. Emahoreni amabili alandelayo, kuthathwa amasampula egazi amaningana ngezikhawu zemizuzu eyi-15-30.
4. Ungabe usuya ekhaya. Kuzodingeka ubuye ngemva kwamahora angu-24 bese uthatha isampula yegazi lokugcina.
5. Amazinga e-FSH, i-LH, namanye ama-hormone ocansi kula masampula egazi ahlolwa elabhorethri.
Kuthiwani uma kukhona okungajwayelekile embikweni wokuhlolwa?
Uma imiphumela yalolu vivinyo iphakeme kakhulu kunokujwayelekile, kungaba uphawu lokuthomba kwasekuqaleni. Udokotela wakho uzokuchazela lokhu ngokuningiliziwe.
Sigcina kanjani isimiso sethu sama-hormone siphilile?
Kunezinto ezimbalwa ezilula esingazenza ukuze sigcine uhlelo lwethu lwe-endocrine, noma uhlelo lwama-hormone, luphilile.
- Vivinya umzimba kahle: Zivocavoce okungenani izinsuku ezimbalwa ngesonto.
- Lala ngokwanele: Thola inani eliqondile lokulala olidingayo ngosuku.
- Gcina isisindo esinempilo: Yidla ukudla okunempilo okunamafutha amancane kanye ne-cholesterol.
- Gwema ukubhema: Uma ubhema futhi usebenzisa imikhiqizo kagwayi, funa usizo lokuyeka. I-Nicotine ingaba nemiphumela emibi ohlelweni lwakho lwama-hormone.
- Phuza imithi yakho ngendlela efanele: Uma unezimo ezihlobene nama-hormone njengesifo sikashukela noma i-thyroid, phuza imithi yakho njengoba nje udokotela wakho ekuyalele.
Imithi ehlobene ne-GnRH (imithi)
Kwezokwelapha, kusetshenziswa imithi eshintsha ukusebenza kwe-hormone ye-GnRH. Lokhu kungamisa ukukhiqizwa kwama-hormone (i-FSH, i-LH) akhuthaza ukukhiqizwa kwama-hormone ocansi yi-pituitary gland.
| Uhlobo lwesidakamizwa (Uhlobo) | Indlela esebenza ngayo |
|---|---|
| Ama-agonist e-GnRH | Lokhu kuqala kushukumisa indlala ye-pituitary ukuthi ikhiqize i-LH ne-FSH eyengeziwe. Kodwa ngemva kwesikhashana, indlala iyeka ukukhiqiza womabili la ma-hormone ngokuphelele. Ngakho-ke, ukukhiqizwa kwama-hormone ocansi nakho kuyayeka. |
| Abaphikisi be-GnRH | Lokhu kuvimbela i-pituitary gland ukuthi ingasabeli ku-GnRH, ngakho-ke i-gland ayikhiqizi i-LH noma ama-hormone ocansi. |
Lo muthi usetshenziselwa ziphi izimo?
Odokotela basebenzisa le mithi ye-GnRH ukwelapha umdlavuza wendlala yabesilisa. Iphinde isetshenziswe ukwelapha lezi zimo ezilandelayo kwabesifazane:
- Umdlavuza webele
- I-Endometriosis
- Ukungabi nabantwana kwabesifazane
- Ukopha kakhulu kokuya esikhathini (i-Menorrhagia)
- Isifo sokuphazamiseka kwengqondo ngaphambi kokuya esikhathini (PMDD)
- Ama-fibroids esibeletho
Umlayezo Wokuya Nawe Ekhaya
- I-GnRH iyi-hormone ebalulekile ekhiqizwa ebuchosheni bethu elawula ukuthomba, isifiso socansi, kanye nokuzala.
- Lokhu kubonisa ukuthi i-pituitary gland ilawula ukukhiqizwa kwama-hormone i-FSH ne-LH.
- Amazinga e-GnRH aphezulu kakhulu noma aphansi kakhulu angabangela izinkinga zokuthomba noma zokuzala ngaphambi kwesikhathi/ukubambezeleka.
- Uma wena noma ingane yakho ninokukhathazeka mayelana nokuthomba, imijikelezo yokuya esikhathini, noma ukuzala, kungcono ukukhuluma nodokotela wakho ngakho.
- Imithi ethinta uhlelo lwe-GnRH isetshenziswa ngempumelelo ukwelapha izimo ezahlukene zezokwelapha.
