testosterone was measured using antibodies raised against testosterone ii b-carboxymethyl ether bovine serum albmin (t-iib-cme-bsa) and testosterone 3- o-carboxymethyl oxime-bsa as immunogen. the antibody produced in this study exhibits minimal cross reactivity with the structurally related steroids specially 5 dihydrotestosterone (5 dhd. this allows to ommit the clean up step and measure testo...

OBJECTIVE To investigate the andropause phenomenon in Iraqi healthy subjects by evaluating serum free testosterone (FT) concentrations in association with age. METHODS This study was carried out at the Biochemistry Department, College of Medicine, University of Baghdad, between February 2012 and October 2012. This cross sectional control subject's study included 251 healthy Iraqi men with an ...

Recent studies have focused on the relationship between nocturia and serum testosterone because testosterone is thought to be an important factor of prostate growth. However, it remains unclear whether altered serum concentrations of testosterone is associated with an increased risk of nocturia because patients who were taking diuretics or who had a large prostate, which may precipitate nocturi...

conclusions it is concluded that dietary supplementation of l-carnitine has no effect on serum levels of estrogen, progesterone and testosterone in cats following ovariohysterectomy. long-term study is recommended. background the benefits of the addition of l-carnitine to the diet of cats to control weight gain after the removal of their ovaries have been highlighted recently. it is also used i...

Testosterone was measured using antibodies raised against testosterone II B-carboxymethyl ether bovine serum albmin (T-IIB-CME-BSA) and testosterone 3- O-carboxymethyl oxime-BSA as immunogen. The antibody produced in this study exhibits minimal cross reactivity with the structurally related steroids specially 5 dihydrotestosterone (5 DHD. This allows to ommit the clean up step and measure ...

OBJECTIVES We compared salivary flow, serum and saliva testosterone, and femur bone mineral density (BMD) of menopausal women with or without xerostomia. STUDY DESIGN A case/control study was performed on 60 selected menopausal women with or without xerostomia. BMD and testosterone concentration were measured by a dual-energy x-ray absorptiometry system and enzyme-linked immunosorbent assay m...

Differentiation between subtle changes in low serum testosterone concentrations, common in women and children, is not possible with current commercially available assays. The objectives of the study were to develop a method based on stable isotope dilution-liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) with adequate sensitivity and specificity and to investigate the applicability ...

Purpose. To compare the hormone levels of patients with seborrheic meibomian gland dysfunction with controls. Procedures. This is a retrospective case-control study involving 50 patients and 50 controls. Blood workup for hormones was studied in both groups by using macroELISA (enzyme-linked immunosorbent assay). Statistical evaluation was done by using SPSS 15.0 independent samples t-test. Resu...

introduction: aim was to study the influence of serum testosterone and urinary citrate on the formation of urinary stones in men and women, and to apply the findings for preventing urolithiasis. methods: we studied 200 patients (100 were men and 100 women) who had referred to the urology clinic at imam khomeini hospital and seda sima eswl center. in both groups, 50 were stone formers and 50 wer...

Monitoring of testosterone replacement therapy requires a reliable method for testosterone measurement. Determination of salivary testosterone, which reflects the hormone's biologically active plasma fraction, is a superior technique for this purpose. The aim of the present study was to establish a new sensitive time-resolved fluorescence immunoassay for the accurate measurement of testosterone...
