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...
Testosterone replacement therapy has benefits for aging men and those with hypogonadism. However, the effects of exogenous testosterone on Leydig cells are still unclear and need to be clarified. In this report, we demonstrate that testosterone supplementation can reduce oxidative damage in Leydig cells. The TM3 Leydig cell line was used as an in vitro cell model in this study. Cytoprotective e...
Purpose Intramuscular (IM) testosterone is the most common modality for testosterone therapy of both male hypogonadism and female-to-male (FTM) gender transition. However, IM injections can be painful and often are not self-administered by the patient. The objective of this study was to further characterize subcutaneous (SC) administration of testosterone as an effective and safe alternative to...
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...
PURPOSE OF REVIEW The purpose of this article is to examine the contemporary data linking testosterone therapy in overweight and obese men with testosterone deficiency to increased lean body mass, decreased fat mass, improvement in overall body composition and sustained weight loss. This is of paramount importance because testosterone therapy in obese men with testosterone deficiency represents...
Background : Diabetes mellitus is a common metabolic disease. Its association with low level of testosterone has already been shown in many studies. Considering the role of testosterone hormone in impotency, fatigue, and bone mass deficiency this study aimed to investigate the association between serum total testosterone, free testosterone index (FTI), and sex hormone-binding globulin (SHBG) ...
The mechanism of the uterotrophic and antiuterotrophic action of testosterone in the rat is unknown. Since testosterone does not compete with estradiol-170 for receptor sites, the possible direct interaction of testosterone with uterine components in the rat was investigated. Following the administration of [aH]testosterone to immature female rats, the hormone is selectively taken up by uterine...
background: although effects of trace elements on secretion of sex steroids and insulin have been studied, the effects of these hormones on serum level of trace elements have been rarely investigated. the aim of the present study was to evaluate the effect of testosterone and finasteride administration and castration on serum levels of testosterone, insulin, zinc and chromium. methods: male adu...
the effects of exposure to chemical weapons containing sulfur mustards on the serum levels of total and free testosterone. gonadotropins and prolactin was investigated in young iranian men. in the first five weeks after injury both serum total and free testosterone were significantly decreased as compared to control values. three of 13 men had total testosterone below 300 ng/dl and two of six h...
