Background: Substance abuse and consequently the use of methadone in Iran are reported at high levels. Drugs alter sexual function by affecting the organs of the body. The aim of this study was to evaluate sexual functioning and serum testosterone levels in opiate addicts, individuals receiving methadone maintenance treatment (MMT), and healthy men living in the city of Rafsanjan, Iran, in 2016...

INTRODUCTION This study was designed to investigate the relationship between serum adiponectin and testosterone in patients with type 2 diabetes. MATERIALS AND METHODS Serum level of adiponectin and testosterone were prospectively measured in 65 patients with type 2 diabetes and in 20 healthy subjects. Testosterone was determined by the radio-immunoassay whereas adiponectin levels were determ...

Prochloraz (PCZ) is an imidazole fungicide that inhibits gonadal steroidogenesis and antagonizes the androgen receptor (AR). We hypothesized that pubertal exposure to PCZ would reduce testosterone production and delay male rat reproductive development. Sprague Dawley rats were dosed by gavage with 0, 31.3, 62.5, or 125 mg/kg/day of PCZ from postnatal day (PND) 23 to 42 or 51. There was a signif...

Aim The Aging process is a major risk factor for the development of degenerative diseases, including cognitive impairment. Many studies have shown that reduced cognitive function is associated with low testosterone levels. This study was aimed to know the association between serum testosterone level and cognitive functions in men who showed mild cognitive impairment. Method This was a cross-sec...

We evaluated a commercial (Radioassay Systems) radioimmunoassay kit for testosterone in which a double-antibody method and an 125I tracer are used. The 50-microL serum sample is assayed directly with no pre-extraction step. The assay system has good sensitivity (0.01 microgram/L), good precision (CV 5.2%), and little cross reactivity between testosterone and other androgens. Results compared we...

BACKGROUND The relationship between the activity of the epiphysis and gonads in rats of different sex and age in different seasons of the year was determined by studying the levels of melatonin and testosterone in the blood plasma. Determination of the levels of melatonin and testosterone in the serum of rats was carried out by enzyme-linked immunosorbent assay. To assess the relationship betwe...

In the article, authors conducted a comprehensive study of interior, including biochemical, physiological, physicochemical, cytogenetic, and other indicators in sheep Romanov breed Western Siberia. For study, blood serum samples were taken from 10 rams-producers 30 lambs at four months. Conventional methods took samples. Analyses performed biochemistry laboratory Novosibirsk State Agrarian Univ...

Andropause is a syndrome described in aging males, is composed of a constellation of physical, sexual, and emotional symptoms, and is thought to be related to declining concentrations of serum testosterone. Numerous studies of testosterone replacement therapy in elderly hypogonadal males have documented the physical benefits of such treatment, but have failed to assess cognition, psychological ...

We have developed an electron capture negative chemical ionization gas chromatography-mass spectrometry (GC-MS) procedure to quantify serum testosterone in the clinically relevant range 0.69-69.3 nmol/L and used this procedure to assess Ciba Corning Diagnostics ACS:180 testosterone immunoassay. The GC-MS method involves liquid-liquid extraction of serum samples and synthesis of a pentafluoroben...

diabetes mellitus is a common metabolic disease. its association with low level of testosterone is controversial. this study aimed to investigate the association between serum total testosterone, free testosterone index (fti), and sex hormone-binding globulin (shbg) in iranian men with type 2 diabetic.a case-control study was conducted on 38 non-diabetic and 36 diabetic men aged 40-60 years old...
