Yintoni uvavanyo lwe-luteinizing hormone (LH)?

Olu vavanyo lilinganisa inqanaba lehomoni ye-luteinizing (LH) egazini lakho. I-LH yenziwa yidlala yakho yebhinqa, incindi encinci ephantsi kwengqondo. I-LH idlala indima ebalulekileyo kuphuhliso lwezesondo kunye nokusebenza.

• Kwabasetyhini, i-LH inceda ukulawula umjikelo wokuya esikhathini. Ikwabangela ukukhutshwa kweqanda kwi-ovary. Oku kwaziwa njenge-ovulation. Amanqanaba e-LH aphakama ngokukhawuleza ngaphambi nje kwe-ovulation.
• Emadodeni, i-LH ibangela ukuba amasende enze i-testosterone, ebalulekileyo ekuveliseni isidoda. Ngokwesiqhelo, amanqanaba e-LH emadodeni awatshintshi kakhulu.
• Kubantwana, amanqanaba e-LH ahlala esezantsi ebuntwaneni, kwaye aqala ukunyuka iminyaka eliqela ngaphambi kokufikisa. Kumantombazana, i-LH inceda ukubonisa ama-ovari ukwenza i-estrogen. Kumakhwenkwe, kuyanceda ukutyikitya ii-testes zokwenza i-testosterone.

Ubuninzi okanye ubuncinci be-LH bunokubangela iingxaki ezahlukeneyo, kubandakanya ukungachumi (ukungakwazi ukukhulelwa), ubunzima bokuya exesheni kwabasetyhini, ukuqhuba ngesondo okuphantsi emadodeni, kunye nokufikisa okanye ukulibaziseka ekufikiseni kubantwana.

Amanye amagama: i-lutropin, iseli yangaphakathi ekhuthaza i-hormone

Isetyenziselwa ntoni?

Uvavanyo lwe-LH lusebenza ngokusondeleyo nenye ihomoni ebizwa ngokuba yi-follicle-stimulating hormone (FSH) yokulawula imisebenzi yesondo. Ke uvavanyo lwe-FSH luhlala lusenziwa kunye novavanyo lwe-LH. Olu vavanyo lusetyenziswa ngeendlela ezahlukeneyo, kuxhomekeka ekubeni ungumfazi, indoda, okanye umntwana.

Kwabasetyhini, ezi mvavanyo zihlala zisetyenziselwa:

• Nceda ufumane unobangela wokungachumi
• Fumanisa ukuba kwenzeka nini ukuphuma kwe-ovulation, eli lixesha apho kunokwenzeka ukuba ukhulelwe.
• Fumana isizathu sokungaqhelekanga okanye sokuyeka ukuya exesheni.
• Qinisekisa ukuqala kokuyeka ukuya exesheni, okanye ixesha lokugqibela. Ukuyeka ukuya exesheni lixesha kubomi bomfazi xa amaxesha akhe okuya exesheni eyekile kwaye akakwazi ukuphinda akhulelwe. Ihlala iqala xa owasetyhini emalunga neminyaka engama-50 ubudala. I-Perimenopause lixesha lokutshintsha ngaphambi kokuyeka ukuya exesheni. Inokuhlala iminyaka eliqela. Uvavanyo lwe-LH lunokwenziwa ukuphela kolu tshintsho.

Emadodeni, ezi mvavanyo zihlala zisetyenziselwa:

• Nceda ufumane unobangela wokungachumi
• Fumana isizathu senani eliphantsi lobudoda
• Fumana isizathu sokuqhuba ngesondo esisezantsi

Kubantwana, ezi mvavanyo zihlala zisetyenziselwa ukunceda ukufumanisa isifo ngaphambi kwexesha okanye ukulibaziseka.

• Ukufikisa kuthathwa kwangethuba ukuba iqala ngaphambi kweminyaka eyi-9 kumantombazana nangaphambi kweminyaka eyi-10 kubafana.
• Ukufikisa kuthathwa njengokulibaziseka ukuba akuqalanga ngeminyaka eli-13 kumantombazana nakwiminyaka eli-14 kubafana.

Kutheni ndifuna uvavanyo lwe-LH?

Ukuba ungumfazi, unokufuna olu vavanyo ukuba:

• Awukwazanga ukukhulelwa emva kweenyanga ezili-12 zokuzama.
• Umjikelo wakho wokuya esikhathini awuqhelekanga.
• Amaxesha akho anqamkile. Uvavanyo lunokusetyenziselwa ukufumanisa ukuba sele ugqithile ekuyekeni ukuya exesheni okanye ukwimeko yokuphela kwexesha.

Ukuba uyindoda, unokufuna olu vavanyo ukuba:

• Khange ukwazi ukumithisa iqabane lakho emva kweenyanga ezili-12 uzama.
• Ukuqhuba kwakho ngesondo kuncitshisiwe.

Bobabini abesilisa nabasetyhini banokufuna ukuvavanywa ukuba baneempawu zesifo sokungabikho komzimba. Oku kubandakanya ezinye zeempawu ezidweliswe apha ngasentla, kunye noku:

• Ukudinwa
• Ubuthathaka
• Ukuhla ukusinda
• Ukunciphisa ukutya

Umntwana wakho unokufuna uvavanyo lwe-LH ukuba akabonakali eqala ukufikisa kwinqanaba elifanelekileyo (nokuba kusekutsha kakhulu okanye emva kwexesha kakhulu).

Kwenzeka ntoni ngexesha lovavanyo lwe-LH?

Ingcali yokhathalelo lwempilo iyakuthatha isampulu yegazi kumthambo engalweni yakho, isebenzisa inaliti encinci. Emva kokuba inaliti ifakiwe, inani elincinci legazi liya kuqokelelwa kwityhubhu yovavanyo okanye igutyana. Unokuziva uluma kancinci xa inaliti ingena okanye iphuma. Oku kuhlala kuthatha imizuzu engaphantsi kwesihlanu.

Ngaba kuya kufuneka ndenze nantoni na ukulungiselela uvavanyo?

Ukuba ungumfazi ongakhange aye esikhathini, umboneleli wakho unokufuna ukucwangcisa uvavanyo lwakho ngexesha elithile ngexesha lokuya esikhathini.

Ngaba bukhona ubungozi kuvavanyo?

Mncinci kakhulu umngcipheko wokuvavanywa kwegazi. Unokuba nentlungu encinci okanye ukrakra kwindawo apho inaliti yafakwa khona, kodwa uninzi lweempawu zihamba ngokukhawuleza.

Zithetha ntoni iziphumo?

Intsingiselo yeziphumo zakho iya kuxhomekeka ekubeni ungumfazi, indoda, okanye umntwana.

Ukuba ungumfazi, amanqanaba aphezulu e-LH anokuthetha ukuba:

• Ayisiyondli. Ukuba uneminyaka yobudala bokuzala, oku kunokuthetha ukuba unengxaki kwii-ovari zakho.Ukuba umdala, oko kunokuthetha ukuba uqalile ukuya exesheni okanye ukwiphulo lokungena exesheni.
• Unesifo se-ovary syndrome (i-PCOS). I-PCOS sisifo esiqhelekileyo esichaphazela ukuzala kwabasetyhini. Sesinye sezizathu eziphambili zokungachumi kwabasetyhini.
• Yiba ne-Turner syndrome, isifo semfuza sichaphazela ukukhula ngokwesondo kubantu basetyhini. Ihlala ibangela ukungachumi.

Ukuba ungumfazi, amanqanaba asezantsi e-LH anokuthetha:

• Idlala lengqula alisebenzi ngokuchanekileyo.
• Unengxaki yokutya.
• Unengxaki yokungondleki.

Ukuba uyindoda, amanqanaba aphezulu e-LH anokuthetha:

• Amatyhalarha akho omoshakele ngenxa ye-chemotherapy, i-radiation, usulelo, okanye utywala.
• Unesifo sikaKlinefelter, isifo semfuza esichaphazela ukukhula ngokwesondo emadodeni. Ihlala ibangela ukungachumi

Ukuba uyindoda, amanqanaba asezantsi e-LH anokuthetha ukuba unesifo se-pituitary gland okanye i-hypothalamus, inxalenye yengqondo elawula i-pituitary gland kunye neminye imisebenzi ebalulekileyo yomzimba.

Kubantwana, amanqanaba aphezulu e-LH, kunye namanqanaba aphezulu e-follicle evuselelayo, kunokuthetha ukuba ukufikisa sele kuza kuqala okanye sele kuqalile. Ukuba oku kuyenzeka ngaphambi kweminyaka yobudala eli-9 kwintombazana okanye ngaphambi kweminyaka eli-10 kwinkwenkwe (ukufikisa kwangaphambili), inokuba luphawu loku:

• Ukuphazamiseka kwenkqubo ye-nervous system
• Ukwenzakala kwengqondo

I-LH ephantsi kunye nenqanaba le-follicle evuselelayo kumanqanaba abantwana kunokuthetha ukuba luphawu lokulibaziseka kokufikisa. Ukulibaziseka kokufikisa kunokubangelwa:

• Ukuphazamiseka kwamaqanda okanye amasende
• I-Turner syndrome kumantombazana
• I-Klinefelter's syndrome kubafana
• Usulelo
• Ukusilela kwehomoni
• Ingxaki yokutya

Funda ngakumbi malunga novavanyo lwelabhoratri, uluhlu lweereferensi, kunye neziphumo zokuqonda.

Ngaba ikhona enye into endifuna ukuyazi malunga novavanyo lwe-LH?

Kukho uvavanyo lwasekhaya olulinganisa amanqanaba e-LH kumchamo. Ikhithi yenzelwe ukufumanisa ukunyuka kwe-LH eyenzeka kanye ngaphambi kokuba i-ovulation. Olu vavanyo lunokukunceda ukuba ufumanise xa uza kutyumba kwaye ube namathuba amahle okukhulelwa. Kodwa akufuneki usebenzise olu vavanyo ukukhusela ukukhulelwa. Ayinakuthenjelwa loo njongo.
