OBJECTIVES To determine serum levels of Follicle Stimulating Hormone (FSH) and Estradiol (E) in peri/postmenopausal women attending the menopause clinic. STUDY DESIGN Retrospective descriptive study. SETTING Siriraj Menopause Clinic, Gynecologic Endocrinology Unit, Division of Reproductive Medicine, Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital. STUDY POPUL...

Serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, estradiol-17 beta and testosterone were determined in adult rats that were treated in the neonatal period with monosodium L-glutamate (MSG) which has previously been shown to reliably produce destruction of arcuate nucleus perikarya. MSG-treated males had significantly smaller accessory sexual organs (semin...

background: it is important to evaluate ovarian reserves prior to intracytoplasmic sperm injection (icsi) treatment. the aim of this study is to determine the accuracy of anti-mullerian hormone (amh) as a marker for ovarian reserve and to compare it with day-3 serum follicle-stimulating hormone (fsh) levels. materials and methods: in this analytic, corss-sectional study, sequential sampling was...

BACKGROUND No polymorphisms affecting serum FSH levels have been described in the human FSHB gene. We have identified a potential regulatory single nucleotide polymorphism (SNP, rs10835638; G/T) 211 bp upstream from the FSHB mRNA transcription start-site, located within a highly conserved region among placental mammals. We aimed to determine the correlation of carrier status of rs10835638 alter...

BACKGROUND The purpose of this study was to compare the effects of hysterectomy and a levonorgestrel-releasing intrauterine system (LNG-IUS) on serum FSH levels and menopausal symptoms. METHODS A total of 236 women referred for menorrhagia to five university hospitals were randomly assigned to treatment with hysterectomy (n = 117) or LNG-IUS (n = 119). Menopausal symptoms were characterized b...

Background: Usage of some atipycal antipsychotic drugs like sulpiride has severed effects on male fertility by impressions on sexual hormones secretion. These hormones regulate male germ cells proliferation and differentiation. In the present study we sought to elucidate the impact of sulpiride on serum prolactin and FSH concentration. Also effect of FSH on spermatogonium A/B (repopulation inde...

OBJECTIVE/BACKGROUND Sickle cell disease is a hereditary hemoglobinopathy characterized by abnormal hemoglobin production, hemolytic anemia, and intermittent occlusion of small blood vessels, leading to tissue ischemia, chronic organ damage, and organ dysfunction including endocrine organs. The aim of this work was to evaluate some gonadal hormones in female children with sickle cell anemia (SC...

The "gonadotropin hypothesis" postulates that gonadotropin overstimulation of ovarian epithelium results in its increased proliferation and subsequent malignant transformation. To address this hypothesis, we assessed the association between prediagnostic serum levels of follicle-stimulating hormone (FSH) and the risk of epithelial ovarian cancer in postmenopausal women who were part of a case-c...

The involvement of FSH and triiodothyronine (T(3)) in circadian clocks was investigated using immature granulosa cells of ovaries during the progress of cell maturation. Granulosa cells were prepared from preantral follicles of mouse Period2 (Per2)-dLuc reporter gene transgenic rats injected subcutaneously with the synthetic nonsteroidal estrogen diethylstilbestrol. Analysis of the cellular clo...

BACKGROUND A long-acting FSH preparation has been developed by site-directed mutagenesis and gene transfer techniques. METHODS In this open-label trial, we investigated the pharmacokinetic and pharmacodynamic properties of FSH-CTP (corifollitropin alpha, Org 36286) in healthy female volunteers. Twenty-four subjects were treated with a high-dose oral contraceptive (OC) to suppress pituitary fu...
