Association of the genetic variants of luteinizing hormone, luteinizing hormone receptor and polycystic ovary syndrome
BACKGROUND High circulating luteinizing hormone (LH) level is a typical biochemical feature of polycystic ovary syndrome (PCOS) whose pathophysiology is still unclear. Certain mutations of LH and LH receptor (LHR) may lead to changes in bioactivity of these hormones. The aim of this study was determine the role of the LH and LHR polymorphisms in the pathogenesis of PCOS using a genetic approach...
متن کاملP-228: Altered Expression of Folliclestimulating Hormone Receptor and Luteinizing Hormone Receptor in Granulosa Cells from Women with Polycystic Ovary Syndrome
Background: Polycystic ovary syndrome (PCOS) is a common complex genetic endocrinopathy, affecting 5 - 10% of women at reproductive age. PCO granulosa cells seem to have abnormal responses to follicle- stimulating hormone (FSH). FSH is considered to be a pituitary glycoprotein that plays an important role during folliculogenesis as it promotes the proliferation and differentiation of granulosa ...
متن کاملExpression of Luteinizing Hormone (LH) Receptor Gene in the Ovary of a Prenatally-Androgenized Rat Model of Polycystic Ovary Syndrome Following Androgen Exposure in the Prenatal Period
Introduction: Based on available evidence, exposure of the female fetus to androgens during the prenatal period, by affecting the expression of some genes, can cause polycystic ovary syndrome (PCOS) in adulthood. On the other hand, changes in luteinizing hormone (LH) levels and its receptor are associated with the risk of reproductive disorders, including PCOS. The present study aimed to evalua...
متن کاملLuteinizing hormone measurement in polycystic ovary syndrome: a practical approach.
The biological diagnosis of polycystic ovary syndrome (PCO) remains questionable, and a single immunological hLH (ihLH) determination can be misleading. In order better to characterize these patients, we studied hLH pulsatility every 10 min for 4h using a radioimmunoassay and then compared the results with others we obtained with a biological method. Radioimmunological and biological profiles w...
متن کاملAssociation of molecular variants of luteinizing hormone with male infertility.
Luteinizing hormone (LH) stimulates the interstitial Leydig cells to produce testosterone, which is essential for spermatogenesis. Abnormalities in the function of LH may affect the process of spermatogenesis and thus result in infertility. The aim of this study was to determine the association of three known variants of LH (Gln54Arg [Trp8Arg; Ile15Thr] and Gly102Ser) with male infertility. A t...
