The interaction between testosterone and exogenous amino acids was studied in older men before and after 6 months of testosterone administration. Twelve healthy older male subjects were randomly assigned in double-blind fashion to receive either testosterone enanthate [T; n = 7; 68 +/- 3 (+/-SE) yr] or placebo (n = 5; 67 +/- 3 yr) for 6 months. Muscle protein kinetics were determined using stab...
OBJECTIVE In the search for long-acting testosterone preparations suited for substitution therapy of hypogonadal men, testosterone undecanoate (TU) dissolved in either tea seed oil or castor oil was investigated. DESIGN In study I, 1000 mg TU in tea seed oil (125 mg/ml) were injected in equal parts into the gluteal muscles of seven hypogonadal men. In study II, 1000 mg TU in castor oil (250 m...
Human cytosolic sulfotransferases (SULT) 2A1 is the main enzyme involved in the sulfate conjugation of dehydroepiandrosterone, a weak androgen, and the main androgen precursor, whereas estrogens are mainly conjugated by SULT1A1. Here we have identified a copy number variation (CNV) polymorphism in the SULT2A1 gene in a Swedish population including healthy men (N = 30). Moreover, the CNV of SULT...
CONTEXT The development of a safe and effective reversible method of male contraception is still an unmet need. OBJECTIVE Evaluation of suppression of spermatogenesis and contraceptive protection by coadministered im injections of progestogen and testosterone. DESIGN Prospective multicentre study. SETTING Ten study centers. PARTICIPANTS Healthy men, aged 18-45 years, and their 18- to 38...
Anabolic androgenic steroids are being more popular between bodybuilders and people who using gym to enhance their physiques. However, according the increase of laws prohibiting sales these substances without physician prescription, route getting administration practices have become dangerous. include many synthetic derivatives testosterone its play a significant role in medical treatment. Thes...
Administration of replacement doses of testosterone to healthy hypogonadal men and supraphysiological doses to eugonadal men increases muscle size. To determine whether testosterone-induced increase in muscle size is due to muscle fiber hypertrophy, 61 healthy men, 18-35 yr of age, received monthly injections of a long-acting gonadotropin-releasing hormone (GnRH) agonist to suppress endogenous ...
Abstract Introduction Klinefelter syndrome (KS) is a genetic condition in which male born with an extra X-chromosome and one of the on-label indications for testosterone replacement therapy (TRT). The prevalence deficiency men KS difficult to predict not well described literature. Furthermore, there no previous literature detailing rates TRT prescription diagnosed KS. Objective We aimed determi...
Androgens stimulate myogenesis, but we do not know what cell types within human skeletal muscle express the androgen receptor (AR) protein and are the target of androgen action. Because testosterone promotes the commitment of pluripotent, mesenchymal cells into myogenic lineage, we hypothesized that AR would be expressed in mesenchymal precursor cells in the skeletal muscle. AR expression was e...
