Ihomoni yeLuteinizing (LH): yintoni kwaye kutheni iphezulu okanye iphantsi

Umxholo

• Yenzelwe ntoni
• Ixabiso lesalathiso se-LH
• Ihomoni ephantsi ye-luteinizing
• IHormone ephezulu ye-luteinizing

Ihomoni ye-luteinizing, ekwabizwa ngokuba yi-LH, yincindi yedlala eveliswa yi-pituitary gland kwaye ethi, kwabasetyhini, inoxanduva lokuvuthwa kwesibeleko, i-ovulation kunye nemveliso yeprogesterone, inendima ebalulekileyo kumandla okuzala komfazi. Emadodeni, i-LH ikwanxulumene ngqo nokuzala, isebenza ngokuthe ngqo kumasende kunye nefuthe ekuvelisweni kwesidoda.

Kumjikelo wokuya exesheni, i-LH ifunyanwa kumanqanaba aphezulu ngexesha lesigaba se-ovulatory, nangona kunjalo ikho kubomi bonke bomfazi, inezinto ezahlukeneyo zokugxila ngokwenqanaba lomjikelo wokuya exesheni.

Ukongeza ekudlaleni indima ebalulekileyo ekuqinisekiseni amandla okuzala kwamadoda nabasetyhini, uxinzelelo lwe-LH egazini luyanceda ekufumaniseni amathumba kwi-pituitary gland kunye notshintsho kwii-ovari, ezinje ngobukho bee-cysts, umzekelo. Olu vavanyo lucelwa ngakumbi ngugqirha wezifo zabasetyhini ukujonga impilo yowasetyhini, kwaye kuhlala kucelwa kunye nomthamo we-FSH kunye neGonadotropin Ukukhupha iHormone, GnRH.

Yenzelwe ntoni

Umlinganiso wehomoni ye-luteinizing egazini ihlala ifuneka ukujonga amandla okuzala komntu kunye nokunceda ekuchongeni ezinye zeenguqu ezinxulumene ne-pituitary, hypothalamus okanye i-gonads. Ke ngoko, ngokwexabiso le-LH egazini, kunokwenzeka:

• Ukuchonga ukungachumi;
• Vavanya amandla emveliso yamadlozi ngumntu;
• Jonga ukuba ngaba umfazi sele eyekile ukuya exesheni;
• Vavanya oonobangela bokungabikho exesheni;
• Jonga ukuba kukho imveliso eyaneleyo yeqanda kwimeko yabafazi;
• Nceda ukufumanisa isifo se-pituitary gland, umzekelo.

Emadodeni, ukuveliswa kwe-LH kulawulwa yi-pituitary gland kwaye isebenza ngokuthe ngqo kumatyhalarha, kulawula ukuveliswa kwesidoda kunye nemveliso yehomoni, ngakumbi i-testosterone. Kwabasetyhini, ukuveliswa kwe-LH yi-pituitary gland kukhuthaza ukuveliswa kweprogesterone, ikakhulu, kunye ne-estrogen, ibalulekile ekukhulelweni.

Ukuvavanya amandla okuzala kwamadoda nabasetyhini, ugqirha unokucela umlinganiso we-FSH, eyihomoni ekhoyo ngokuya exesheni komfazi kwaye ichaphazela imveliso yesidoda. Qonda ukuba yeyantoni kwaye ungasiqonda njani isiphumo se-FSH.

Ixabiso lesalathiso se-LH

Ixabiso lesalathiso sehomoni ye-luteinizing iyahluka ngokobudala, isini kunye nenqanaba lomjikelo wokuya exesheni, kwimeko yabasetyhini, ngala maxabiso alandelayo:

Abantwana: ngaphantsi kwe-0.15 U / L;

Amadoda: phakathi kwe0.6 - 12.1 U / L;

Abafazi:

• Isigaba sesigaba: phakathi ko-1.8 no-11.8 U / L;
• Incopho ye-Ovulatory: phakathi ko-7.6 no-89.1 U / L;
• Isigaba seLuteal: phakathi kwe-0.6 kunye ne-14.0 U / L;
• Ukuyeka ukuya exesheni: phakathi ko-5.2 no-62.9 U / L.

Uhlalutyo lweziphumo zeemviwo kufuneka lwenziwe ngugqirha, njengoko kufanelekile ukuhlalutya zonke iimviwo kunye, kunye nokuthelekisa neemviwo zangaphambili.

Ihomoni ephantsi ye-luteinizing

Xa amaxabiso e-LH angaphantsi kwexabiso lesalathiso, inokubonisa:

• Ukutshintsha kobume, kukhokelela ekucutheni imveliso ye-FSH kunye ne-LH;
• Ukusilela kwimveliso ye-gonadotropin (GnRH), eyihomoni eveliswayo kwaye ikhutshwe yi-hypothalamus kwaye umsebenzi wayo kukhuthaza i-pituitary gland ukuba ivelise i-LH kunye ne-FSH;
• Isifo sikaKallmann, esisifo semfuza kunye nelifa elibonakaliswa kukungabikho kwemveliso ye-GnRH, ekhokelela kwi-hypogonadotrophic hypogonadism;
• Hyperprolactinemia, elonyuko kwimveliso yehomoni yeprolactin.

Ukwehla kwe-LH kungakhokelela ekwehleni kwimveliso yamadlozi ngamadoda kunye nokungabikho exesheni kwabasetyhini, imeko eyaziwa ngokuba yi-amenorrhea, kwaye kubalulekile ukudibana nogqirha ukubonisa unyango olulungileyo, oluqhele ukwenziwa Ukusetyenziswa kwesongezelelo sehomoni.

IHormone ephezulu ye-luteinizing

Ukonyuka koxinzelelo lwe-LH kunokubonisa:

• Ithumba lesisu, ngokunyuka kwe-GnRH kwaye, ngenxa yoko, ukugcinwa kwe-LH;
• Ukufikisa kwangethuba;
• Ukungaphumeleli kovavanyo;
• Ukuya exesheni;
• Isifo sePolycystic Ovary Syndrome.

Ukongeza, ihomoni ye-LH inokunyuswa xa ukhulelwe, kuba ihomoni ye-hCG inokulinganisa i-LH, kwaye inokubonakala iphakanyisiwe kwiimviwo.
