Metabolic Effects of Steroids in Obese Men

2014-07-23 21:12:40 | BioPortfolio

Summary

Subjects will be randomized into 4 study groups: 1. Placebo; 2. Anastrazole and Testosterone; 3. Dutasteride and Testosterone; and 4. Testosterone only. A 2 step euglycemic clamp, body composition by dual X-ray absorptiometry scan, hormone and lipid assays will be performed to monitor metabolic effects of each treatment group. We hypothesize that increasing testosterone levels would increase lean mass, decrease fat mass and improve insulin sensitivity. We further hypothesize that improvements in the metabolic profile would decrease with anastrazole and improve with dutasteride, given in conjunction with T administration.

Medical and Biotech [MESH] Definitions

Steroidal compounds related to TESTOSTERONE, the major mammalian male sex hormone. Testosterone congeners include important testosterone precursors in the biosynthetic pathways, metabolites, derivatives, and synthetic steroids with androgenic activities.

A potent androgenic metabolite of TESTOSTERONE. Dihydrotestosterone (DHT) is generated by a 5-alpha reduction of testosterone. Unlike testosterone, DHT cannot be aromatized to ESTRADIOL therefore DHT is considered a pure androgenic steroid.

A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.

A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as diabetes, hypertension and METABOLIC SYNDROME X.

An ester of TESTOSTERONE with a propionate substitution at the 17-beta position.
