I-Luteinizing hormone (LH), okuyinto evamile kubaluleke kakhulu kwabesifazane nabodokotela abaningi, ingenye yama-hormone ayisithupha abaluleke kunawo wonke abanjwe yi-pituitary gland, enikeza ukulungiselela ukukhulelwa kanye nendlela ejwayelekile.
Ukuxilonga i-hormone kubangela ukuthi i-hormone ye-sex hormone progesterone ne-sex hormone testosterone ikhiqizwa kanjani.
Isimiso se-LH kwabesifazane singahlukana hhayi kuphela ekuthembekeni okuthile ngosuku lomjikelezo, isimo sowesifazane, kodwa futhi kuncike eminyakeni yobudala. Ake sicabangele lezi zinkomba.
LH - okujwayelekile kubantu besifazane
Uma umzimba wesifazane ukhiqiza i-hormone ye-L eyanele ngokwanele, okujwayelekile kubantu besifazane kule hormone kungatholakala ngemiphumela yokuhlolwa kwegazi. Ngakho:
- umkhuba we-LH esigabeni se-follicular (okungukuthi, kusukela ezinsukwini ezingu-1 kuya kwezingu-14 zonyaka wokuya esikhathini) kusuka ku-2 kuya ku-14 mU / L;
- umkhuba we-hormone ngesikhathi sokuvuthwa (kusukela ezinsukwini ezingu-12 kuya kwezingu-16 zomjikelezo) kusuka ku-24 ukuya ku-150 mU / L;
- umkhuba we-LH esigabeni esilandelayo (okungukuthi, kusukela ngosuku lweshumi nanhlanu kuya kwezingu-15 kuya kokuqala komjikelezo olandelayo) kusuka ku-2 kuya ku-17 mU / L.
Amazinga aphakeme kakhulu ale hormone kubesifazane asikisela:
- isifo sokukhathala noma i-polycystic ovary;
- ukwehluleka kwenqunu;
- ukuthuthukiswa kwesisu se-pituitary;
- i-endometriosis;
- ukungakwazi ukusebenza kwe-gonads.
Ngaphezu kwalokho, i-LH kwabesifazane inganyuswa ngesikhathi sokuzila, ukuqeqeshwa kwezemidlalo okujulile (okuyiyo isizathu sokungabi nabantwana besifazane abadlala emidlalweni yezemidlalo), kanye nokucindezeleka.
Izinga eliphansi le-LH, njengombuso, likhuluma ngalokhu:
- Isigaba sokungasebenzi ngokwanele;
- isifo se-polycystic ovaries;
- ngokweqile kwezinga le-hormone prolactin;
- i-hypothalamic aminoray yesibili.
Izinga le-LH liyancipha futhi ngokukhuluphala, ukucindezeleka, ukuphuza ukukhula, ukubhema.
LH ekukhulelweni kuvamile
Kubalulekile ukukhumbula ukuthi lapho ukhulelwe, izinga lokumisa i-hormone lihlale linciphile. Lokhu kubhekwa njengesikhombisa esivamile futhi kunomthelela ekulondolozeni ukukhulelwa nokugcinwa kwayo.
I-hormone ye-L iyinhlangano evamile
Emantombazaneni, amantombazane, abesifazane, i-LH ihlukahluka kulo lonke impilo. Ake sichaze lezi zinkomba. Isibonelo, eneminyaka engu-1 kuya kwemi-3 ubudala, izinga le-hormone libhekwa njengejwayelekile kusukela ku-0.9 mU / l kuya ku-1.9 mU / L, lentombazane eneminyaka engu-14 ubudala-kusuka ku-0.5 mU / L kuya ku-25 mU / L, futhi Uneminyaka engu-18 ubudala - kusuka ku-2.3 mU / L kuya ku-11 mU / L.
Imikhuba yabesifazane yokuzalwa kweminyaka, isetshenziselwa izigaba ezahlukene zokujikeleza kokuya esikhathini, inikelwa ngenhla. Esikhathini esibucayi, izinga le-LH kwabesifazane lihluka kusuka ku-14.2 kuya ku-52.3 mU / l.
Kumele futhi kukhunjulwe ukuthi imigomo ecashunwe ngokulinganayo isifinyelele, ngakho-ke, ukuthi ngisho owesifazane oyedwa angahluka kanjani, kuye ngokuthi isimo senyama.
Ukuhlaziywa kwe-LH kuvamile kubantu besifazane
Ukuze ukuhlaziywa kwe-LH kwenziwe ngendlela efanele, imithetho elandelayo ebalulekile kumele ibonwe:
- igazi lokuhlaziywa kufanele lithathwe ngokuqinile ekuseni nangesisu esingenalutho, kanye nanoma yikuphi ukuhlaziywa kwama-hormone;
- ukuze wazi umkhuba we-LH esigabeni se- follicular , ukuhlaziywa kufanele kwenziwe kusukela ngosuku lwesithathu nango-8 lomjikelezo;
- ukwazi isiko se-LH esigabeni esilandelayo, ukuhlaziywa kufanele kwenziwe kusukela ezinsukwini ezingu-19 kuya kwezingu-21 zomjikelezo;
- usuku olulodwa ngaphambi kokuhlolwa, awukwazi ukuphuza utshwala, ukudla okunamafutha namaswidi.
Lokhu kuhlaziywa kuvame ukuphathwa ngokungasebenzi, i-endometriosis, i-polycystic ovary syndrome. Kuhlala njalo kwenziwa ukunquma isikhathi sokuvuthwa, ne-IVF ( in vitro fertilization ).
Naphezu kokuthi kubafazi izinga le-LH emzimbeni lihluke njalo, kunemikhuba yezokwelapha esinqumayo ukungaphezu kwalokho noma ukungakwazi ukusebenza kwe-hormone ebalulekile.
