Primary Hyperparathyroidism is a condition in which parathyroid gland secrets high levels of Parathyroid hormone and loses the ability to regulate Parathyroid hormone secretion via a negative feedback mechanism with serum calcium level (Geffken 1998). This hormone increases serum calcium by increasing bone resorption, intestinal absorption and decreasing renal excretion resulting in vicious cyc...

Background: Anti-Mullerian hormone (AMH) has been suggested as a marker of ovarian reserve and predictor of ovarian response to controlled ovarian hyper stimulation. The aim of this study is to determine the role of AMH in prediction of success ART cycles in patients with normal FSH serum levels. Materials and Methods: This prospective cohort study included 80 infertile women under 4o years, wh...

OBJECTIVE To evaluate serum total and lipid bound sialic acid (TSA&LBSA) levels in patients with polycystic ovary syndrome (PCOS). MATERIAL AND METHODS Forty women with PCOS and 35 healthy controls were enrolled in the study. Serum TSA, LBSA, follicle stimulating hormone, lutenizing hormone, estradiol, thyroid stimulating hormone, prolactin, dehydroepiandrosterone sulphate, androstenedione, f...

introduction: thyroid hormones play an important role in the regulation of metabolism, maturity and reproduction. thyroid dysfunction affects almost all endocrine glands such as pituitary and testis. the aim of this study was to investigate alterations of testosterone and luteinizing hormone (lh) serum levels as well as weights of thyroid gland and testes in methimazole (mmi)-induced hypothyroi...

The double antibody radioimmunoassay of serum thyroid-stimulating hormone (TSH) allows measurement of circulating levels of the hormone in most normal subjects. The serum TSH level in normal subjects is 1.6 +/- 0.8muU/ml. Patients with non-toxic goitre and acromegaly have normal TSH levels. Values are always raised in hypothyroid patients (with primary thyroid disease) and are significantly low...

BACKGROUND To discuss the meaning of serum oestradiol monitoring in frozen embryo transfer cycle using hormone replacement without pretreatment with gonadotropin hormone (GnRH) agonist. METHODS The data from two hundred twelve women undergoing two hundred seventy-four frozen-thawed embryo transfer (FET) cycles was included in this retrospective cohort study. They were detected of serum oestra...

Background and Objective: Chronic Kidney Disease-Mineral Bone Disorder (CKD-MBD) is characterized by hypocalcemia, hyperphosphatemia and abnormal vitamin D (VD) metabolism resulting in high parathyroid hormone secretion. The objective of the study was to determine VD status in children with CKD-MBD and the effect of cholecalciferol therapy in these children. Methods: This quasi-experimental st...

BACKGROUND Anti-Müllerian hormone (AMH) is secreted by the granulosa cells of growing follicles during the primary to large antral follicle stages. Abnormal levels of AMH and follicle stimulating hormone (FSH) may indicate a woman's diminished ability or inability to conceive. Our aim is to investigate the changes in serum AMH and FSH concentrations at different age groups and its correlation w...

This study addresses how growth during sensitive developmental periods and genes may affect hormone levels in late adolescence. We analyzed hormone levels of dehydroepiandrosterone sulfate (DHEAS) and insulin-like growth factor-I (IGF-I), which are hypothesized to be two pathways linking early growth with adult diseases (such as type 2 diabetes and cardiovascular disease) via their effects on e...
