Impendulo ye-LH kuvavanyo lwegazi lwe-GnRH
Impendulo ye-LH kwi-GnRH luvavanyo lwegazi ukunceda ukumisela ukuba isifo sakho se-pituitary singaphendula ngokuchanekileyo kwi-gonadotropin ekhupha i-hormone (GnRH). I-LH imele i-luteinizing hormone.
Kuthathwa isampulu yegazi, emva koko unikwe umfanekiso weGnRH. Emva kwexesha elichaziweyo, iisampulu zegazi ezininzi zithathwa ukuze i-LH ikwazi ukulinganiswa.
Akukho lungiselelo lukhethekileyo luyimfuneko.
Xa kufakwa inaliti ukutsala igazi, abanye abantu baziva iintlungu eziphakathi. Abanye baziva behlaba okanye behlaba kuphela. Emva koko, kunokubakho ukubetha okanye ukukrala kancinci. Oku kuya kuhamba kungekudala.
I-GnRH yincindi yedlala eyenziwe yindlala yehypothalamus. I-LH yenziwa yidlala yebhinqa. I-GnRH ibangela (ivuselele) i-pituitary gland ukukhupha i-LH.
Olu vavanyo lusetyenziselwa ukuxelela umahluko phakathi kwe-hypogonadism yamabanga aphantsi kunye nasesekondari. I-Hypogonadism yimeko apho amadlala esini enza i-hormone encinci okanye engenawo kwaphela. Emadodeni, amadlala esini (iigonads) luvavanyo. Kwabasetyhini, amadlala esini zii-ovari.
Kuxhomekeka kuhlobo lwe-hypogonadism:
- I-hypogonadism yaseprayimari iqala kwisende okanye kwi-ovary
- I-hypogonadism yesibini iqala kwi-hypothalamus okanye kwi-pituitary gland
Olu vavanyo lunokwenziwa ukujonga:
- Inqanaba le testosterone eliphantsi emadodeni
- Inqanaba le-estradiol esezantsi kwabasetyhini
Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo. Ezinye iilebhu zisebenzisa imilinganiselo eyahlukeneyo okanye ukuvavanya iisampulu ezahlukeneyo. Thetha nomboneleli wakho wezempilo malunga nentsingiselo yeziphumo zakho zovavanyo.
Impendulo eyandisiweyo ye-LH iphakamisa ingxaki kwii-ovari okanye kwiimvavanyo.
Impendulo encitshisiweyo ye-LH iphakamisa ingxaki kwi-hypothalamus gland okanye i-pituitary gland.
Iziphumo ezingaqhelekanga zinokubangelwa:
- Iingxaki ze-pituitary gland, njengokukhutshwa kwehomoni eninzi (hyperprolactinemia)
- Amathumba amakhulu ebhinqa
- Ukuhla kwehomoni eyenziwe ngamadlala endocrine
- Intsimbi eninzi emzimbeni (hemochromatosis)
- Ukuphazamiseka kwindlela yokutya, njengeanorexia
- Kutshanje ukunciphisa umzimba, njengasemva koqhaqho lwe-bariatric
- Ukulibaziseka okanye ukungabikho kobuntwana (Isifo seKallmann)
- Ukungabikho kwamaxesha kwabasetyhini (amenorrhea)
- Ukutyeba kakhulu
Akukho mngcipheko ubandakanyekileyo ekuthatheni igazi lakho. Imithambo kunye nemithambo iyahluka ngobukhulu ukusuka komnye umntu ukuya komnye nakwelinye icala lomzimba liye kwelinye. Ukuthatha igazi kwabanye abantu kunokuba nzima ngakumbi kunabanye.
Eminye imingcipheko enxulumene nokutsalwa kwegazi incinci, kodwa inokubandakanya:
- Ukopha kakhulu
- Ukufa isiqaqa okanye ukuziva ungenantloko
- Ukugqobhoza okuninzi ukufumana imithambo
- I-Hematoma (igazi eliqokelela phantsi kwesikhumba)
- Usulelo (umngcipheko omncinci nangaliphi na ixesha ulusu lwaphukile)
