We compared the clinical value of information on free testosterone as measured with the Coat-A-Count (Diagnostic Products Corp.) radioimmunoassay kit involving a ligand analog with that of total testosterone, the free-androgen index, and free testosterone calculated from concentrations of testosterone, sex-hormone-binding globulin, and albumin, in hirsute women, pregnant women, oral-contracepti...

Blood-free testosterone indices were measured among 28 normal men (age; 24-48 yrs.), 20 normal women (20-36 yrs.), 18 pregnant women (22-31 yrs.), 17 males with hypogonadism (23-56 yrs.), 17 males with chronic hepatitis (20-42 yrs.), 24 males with liver cirrhosis (29-68 yrs.), 34 males with hyperthyroidism (20-42 yrs.) and 7 hirsute women (18-31 yrs.), and these were compared with the plasma co...

INTRODUCTION AND OBJECTIVES The best indicators to the diagnosis of hypogonadism are free and bioavailable testosterone circulating levels. Free and bioavailable testosterone measurements are complex. However, simple kits for direct measurement of free testosterone by analog immunoassay are available. We examined the utility of an enzymoimmunoassay kit for free testosterone measurement. MATER...

OBJECTIVE: To evaluate the relationship between serum level of testosterone and sex hormone-binding globulin in men with type 2 diabetes. MATERIALS AND METHODS: In this case-control study, forty men aged 40-70 with type 2 diabetes mellitus were randomly selected and compared with 40 non-diabetic men. The two groups were matched for their age and BMI. After complete observation and examination...

introduction: boron possesses widespread properties and is important for human and animal nutrition. since boron is rapidly bioavailable, the objective of the present study was to determine whether acute (hourly or daily), and weekly supplementationcould have any significant biological effects on the synthesis of steroids as well as inflammatory biomarkers. methods: eight male volunteers partic...

Men with low testosterone concentrations are usually hypogonadal. However, because variations in the testosterone transport protein, sex hormone-binding globulin (SHBG), directly influence the total testosterone concentration, confirmation of a low testosterone with a measurement of free testosterone or "bioavailable" testosterone (BAT) is recommended. In the present study, we examined the rela...

Recently, it has been concluded that measurement of the serum free testosterone level is crucial for evaluating male gonadal function. However, the extent of the decline of serum free testosterone levels with aging and the actual levels in male infertility have not yet been clearly defined. In this study, the clinical significance of serum free testosterone levels was evaluated in a total of 24...

Background After American occupation to Iraq, no day passed without terrorist attacks or explosion in Iraq. The impact of this events extends to interact with all fields of life. The present study was designed to investigate the basal levels of hormones that affect sexual life of men patients with posttraumatic stress disorder (PTSD) and control group. MaterialsAndMethods Eighty two males witne...
