objectives: this study was conducted in order to analyse the effect of flat pyramid loading pattern (fplp) weight training on salivary steroids levels in strength training athletes. methods: eleven elite male weightlifters trained six days per week for one month. five millilitres of unstipulated whole saliva was obtained pre- and five minutes post-exercise at days first, 15th, and 30th. results...

OBJECTIVES To assess the correlations between blood levels of sex steroid hormones and blood lipid profile or the degree of coronary artery stenosis in men with coronary artery disease (CAD). METHODS 111 men with stable CAD, aged 36-73 yrs, unselected for the coexisting clinical coronary risk factors were prospectively studied. Degree of coronary stenosis was assessed angiographically using d...

M en with obesity, the metabolic syndrome, and type 2 diabetes have low total and free testosterone and low sex hormone–binding globulin (SHBG). Conversely, the presence of low testosterone and/or SHBG predicts the development of metabolic syndrome and type 2 diabetes. Visceral adiposity present in men with low testosterone, the metabolic syndrome, and/or type 2 diabetes acts through proinflamm...

BACKGROUND To evaluate the effect of internal spermatic vein (ISV) embolization on levels of serum testosterone and free testosterone and on spermatogenesis. METHODS The files of 83 infertile men treated for varicocele were reviewed for changes in serum testosterone, free testosterone and spermatogenesis after ISV embolization. RESULTS Mean serum testosterone concentration rose after emboli...

OBJECTIVE Low levels of androgens in men may play a role in the development of diabetes; however, few studies have examined the association between androgen concentration and diabetes in men in the general population. The objective of this study is to test the hypothesis that low normal levels of total, free, and bioavailable testosterone are associated with prevalent diabetes in men. RESEARC...

OBJECTIVE This study was to demonstrate that Sal-T is a reliable biomarker of androgen status in the diagnosis of male hypogonadism. DESIGN In order to validate the salivary testosterone assay (Sal-T), its reproducibility, the agreement with serum free testosterone levels (Free-T), the correlation with other circulating androgen markers (bioavailable testosterone, total testosterone) and cut-...

Abstract Introduction Erectile dysfunction (ED) is a disease that affects approximately 20% of adult men. Androgen deficiency one the organic etiologies described for this sexual dysfunction. Objective To estimate frequency alterations in sex hormone binding globuline (SHBG), total testosterone (TT), calculated free (FT) and bioavailable (BT) Spanish men with clinical diagnosis erectile Madrid,...

Previous studies have demonstrated that male hypogonadism is associated with a low level of vitamin D. However, no reports have investigated the effects of vitamin D on testosterone levels in Korean men. Our aim was to investigate whether testosterone levels are associated with serum vitamin D levels and whether seasonal variation exists. This cross-sectional study analyzed serum 25-hydroxyvita...

BACKGROUND Sex steroids can positively affect the brain and from this it would follow that high levels of sex steroids could be associated with better cognitive function in older men and women. METHODS This Healthy Ageing Study sample comprised of 521 older participants (51% women) without dementia at baseline, with an age range from 64 to 94 years. Testosterone and sex hormone binding globul...

A two-period, randomized, complete crossover study was performed to evaluate the pharmacokinetic profiles of Testim (AA2500), a new 1% testosterone topical gel formulation, compared to AndroGel, an already available 1% testosterone topical gel. Twenty-nine hypogonadal subjects received a single dose (50 mg testosterone) of each formulation seven days apart. C(max) estimates for total testostero...
