Selective androgen receptor modulators (SARMs) now under development can protect against muscle and bone loss without causing prostate growth or polycythemia. 17β-Hydroxyestra-4,9,11-trien-3-one (trenbolone), a potent testosterone analog, may have SARM-like actions because, unlike testosterone, trenbolone does not undergo tissue-specific 5α-reduction to form more potent androgens. We tested the...

The UDP Glucuronosyl Transferase (UGT) enzymes are important in the pharmacokinetics, and conjugation, of a variety of drugs including non-steroidal anti-inflammatory drugs (NSAIDs) as well as anabolic androgenic steroids (AAS). Testosterone glucuronidation capacity is strongly associated with a deletion polymorphism in the UGT2B17 gene. As the use of high doses of NSAIDs has been observed in a...

The present study was undertaken to compare the release of testosterone and its derivatives in adult male bonnet monkeys by different routes. Testosterone and its derivatives such as T.propionate, T.enanthate, T.undecanoate, T.busiclate and 7 -Methyl 19-nortestosterone (MENT) were administered via different routes that includes intramuscular, Alzet pump and Silastic tubing. It was observed that...

testosterone enanthate (te) is used by many athletes as a muscle builder. previous studies showed that high concentration of the drug in plasma may affect the natural function of endocrine glands, specially the secretion of the adrenocortical hormones. the objective of the present study was to examine the effects of high concentration of te on histometrical structure of adrenal cortex in male r...

androgens have been shown to affect cognitive aspects of spatial memory. testosterone which is the most important androgen, plays a role in the organization of behavior during development. also, it has been shown that androgens cause sex related differences in learning and memory especially during neonatal period. in the current study, we assessed the effects of castration and testosterone enan...

BACKGROUND Cholesterol is mainly synthesised in liver and the rate-limiting step is the reduction of 3-hydroxy-3methylglutaryl coenzyme A (HMG-CoA) to mevalonate, a reaction catalysed by HMG-CoA reductase (HMGCR). There is a comprehensive body of evidence documenting that anabolic-androgenic steroids are associated with deleterious alterations of lipid profile. In this study we investigated whe...

Background: Chemotherapy or irradiation is associated with impaired fertility. The aim of this study was to investigate the possible protective role of testosterone enanthate (TE) on the proliferative activity, plasma testosterone level and morphometry of epithelial cells of seminal vesicles in busulfan-induced spermiotoxicity. Materials and Methods: Sprague- Dawley rats were divided into 4 gro...
