I-Luteinizing hormone (LH): iyini nokuthi kungani iphakeme noma iphansi

-Delile

• Yenzelwe ini
• Amanani esithenjwa se-LH
• I-hormone ephansi ye-luteinizing
• Ama-hormone aphezulu e-luteinizing

Ihomoni ye-luteinizing, ebizwa nangokuthi i-LH, iyi-hormone ekhiqizwa yi-pituitary gland futhi, kwabesifazane, enesibopho sokuvuthwa kwe-follicle, ukukhiqizwa kwe-ovulation kanye ne-progesterone, enendima ebalulekile emkhakheni wokuzala wesifazane. Emadodeni, i-LH nayo ihlobene ngqo nokuzala, isebenza ngqo kumasende futhi inethonya ekukhiqizeni isidoda.

Emjikelezweni wokuya esikhathini, i-LH itholakala ekugxileni okuphezulu ngesikhathi sesigaba se-ovulatory, noma kunjalo ikhona kuyo yonke impilo yowesifazane, inokugxila okuhlukile ngokwesigaba somjikelezo wokuya esikhathini.

Ngaphezu kokubamba iqhaza elibalulekile ekuqinisekiseni amandla okuzala abesilisa nabesifazane, ukugxila kwe-LH egazini kuyasiza ekutholeni izicubu ezisegunjini le-pituitary kanye nezinguquko kuma-ovari, njengokutholakala kwama-cysts, ngokwesibonelo. Lokhu kuhlolwa kucelwa kakhulu ngudokotela wezifo zabesifazane ukuthi ahlole impilo yowesifazane, futhi kuvame ukucelwa kanye nomthamo we-FSH neGonadotropin Releasing Hormone, GnRH.

Yenzelwe ini

Isilinganiso se-luteinizing hormone egazini imvamisa siyadingeka ukuhlola amandla okuzala komuntu futhi sisize ekutholeni ezinye zezinguquko ezihlobene ne-pituitary, hypothalamus noma i-gonads. Ngakho-ke, ngokuya ngenani le-LH egazini, kungenzeka:

• Xilonga ukungazali;
• Linganisa amandla wokukhiqizwa kwesidoda ngumuntu;
• Bheka ukuthi owesifazane ukungenile yini ukuya esikhathini?
• Hlola izimbangela zokungabikho kokuya esikhathini;
• Bheka ukuthi ngabe kukhona yini ukukhiqizwa kwamaqanda okwanele kwabesifazane;
• Siza ekutholeni isimila endleleni yesibeletho, ngokwesibonelo.

Emadodeni, ukukhiqizwa kwe-LH kulawulwa yi-pituitary gland futhi kusebenza ngqo kumasende, kulawula ukukhiqizwa kwesidoda nokukhiqizwa kwamahomoni, ikakhulukazi i-testosterone. Kwabesifazane, ukukhiqizwa kwe-LH ngendlala ye-pituitary kukhuthaza ukukhiqizwa kwe-progesterone, ikakhulukazi, ne-estrogen, kubalulekile ekukhulelweni.

Ukuhlola amandla okuzala abesilisa nabesifazane, udokotela futhi angacela ukulinganiswa kwe-FSH, eyi-hormone nayo ekhona esikhathini sokuya esikhathini sowesifazane futhi ethonya ukukhiqizwa kwesidoda. Qonda ukuthi yenzelwe ini nokuthi uwuqonde kanjani umphumela we-FSH.

Amanani esithenjwa se-LH

Amanani ayizethenjwa e-luteinizing hormone ayahluka ngokuya ngeminyaka, ubulili kanye nesigaba somjikelezo wokuya esikhathini, esimweni sabesifazane, ngamanani alandelayo:

Izingane: ngaphansi kuka-0,15 U / L;

Abesilisa: phakathi kuka-0.6 - 12.1 U / L;

Abesifazane:

• Isigaba esilandelayo phakathi kuka-1.8 no-11.8 U / L;
• Ukuphakama okuvuthayo: phakathi kuka-7.6 no-89.1 U / L;
• Isigaba se-Luteal: phakathi kuka-0.6 no-14.0 U / L;
• Ukunqamuka kokuya esikhathini: phakathi kuka-5.2 no-62.9 U / L.

Ukuhlaziywa kwemiphumela yezivivinyo kumele kwenziwe ngudokotela, ngoba kuyadingeka ukuhlaziya zonke izivivinyo ndawonye, ​​kanye nokuqhathanisa nezivivinyo ezedlule.

I-hormone ephansi ye-luteinizing

Lapho amanani we-LH engaphansi kwenani lesethenjwa, angakhombisa:

• Ukuguqulwa kwesimo, okuholela ekwehliseni ukukhiqizwa kwe-FSH ne-LH;
• Ukushoda ekukhiqizeni i-gonadotropin (GnRH), eyi-hormone ekhiqizwa futhi ikhishwe yi-hypothalamus futhi umsebenzi wayo ukuvuselela indlala ye-pituitary ukuthi ikhiqize i-LH ne-FSH;
• I-Kallmann's syndrome, okuyisifo sofuzo nesofuzo esibonakala ngokungabikho komkhiqizo we-GnRH, oholela ku-hypogonadotrophic hypogonadism;
• I-Hyperprolactinemia, okungukukhuphuka kokukhiqizwa kwe-hormone prolactin.

Ukwehla kwe-LH kungaholela ekwehleni kokukhiqizwa kwesidoda ngabesilisa futhi lapho kungayi esikhathini kwabesifazane, isimo esaziwa ngokuthi i-amenorrhea, futhi kubalulekile ukubonisana nodokotela ukukhombisa ukwelashwa okuhle kakhulu, okuvame ukwenziwa ukusetshenziswa kwe-hormonal supplementation.

Ama-hormone aphezulu e-luteinizing

Ukwanda kokuhlushwa kwe-LH kungakhombisa:

• Isimila sesikhumba, ngokunyuka kwe-GnRH futhi, ngenxa yalokho, uketshezi lwe-LH;
• Ukuthomba kusenesikhathi;
• Ukwehluleka kobufakazi;
• Ukunqamuka kokuqala;
• I-Polycystic Ovary Syndrome.

Ngaphezu kwalokho, i-hormone ye-LH ingakhuphuka lapho ukhulelwe, ngoba i-hCG hormone ingalingisa i-LH, futhi ingahle ibonakale iphakeme ezivivinyweni.
