Heart failure (HF) is a complex condition resulting from structural or functional heart diseases that impair the ability of the heart to fill with or pump out blood. The main manifestations of HF are shortness of breath and tiredness which may limit the ability to exercise or perform simple daily physical activities such as walking. Heart disease leading to HF is associated with reduced muscle mass and reduced strength and low blood levels of testosterone; a hormone normally produced by the human (male and female) body. Recent studies have shown improvements of symptoms and ability to exercise in patients with heart failure receiving testosterone.
This is a placebo controlled study to determine the efficacy and safety of low dose testosterone (300 and 450 microgram/day) delivered by a transdermal system (patch) in women with significant HF.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
placebo, 300 µg/day testosterone, 450 µg/day testosterone

The purpose of this study is to determine whether a proprietary 'testosterone-boosting' supplement, when used as recommended by the manufacturer, results in an increase in testosterone lev...
The purpose of this trial is to evaluate the effect of testosterone replacement in men with renal failure (on dialysis) who also have low testosterone. Specifically, we will assess the cha...
We hypothesize that testosterone replacement will improve mood and quality of life in older men with low testosterone and mild depression. Study subjects will receive either testosterone g...
The Testosterone Trials are a multi-center set of trials involving 12 clinical sites geographically distributed across the United States. The primary specific aims are to test the hypothe...
The purpose of this study is to examine the effect of having testosterone deficiency in men with diabetes and with obesity. The study will also evaluate the effect of testosterone therapy....
The Testosterone Trials (TTrials) were a coordinated set of seven, placebo-controlled, double blind trials in 788 men of mean age 72 years to determine the efficacy of increasing the testosterone leve...
Studies of the possible cardiovascular risk of testosterone treatment are inconclusive.
Testosterone treatment of men with low testosterone is common and, although relatively short-term, has raised concern regarding an increased risk of prostate cancer (CaP). We investigated the associat...
Testosterone is commonly measured using immunoassays, yet concerns with the accuracy and quality of testing by these methods exist, particularly for low testosterone concentrations. Study objectives w...
To summarize the research evidence on promotion of testosterone for 'Low T', or age-related hypogonadism.
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.
An ester of TESTOSTERONE with a propionate substitution at the 17-beta position.
The 17-alpha isomer of TESTOSTERONE, derived from PREGNENOLONE via the delta5-steroid pathway, and via 5-androstene-3-beta,17-alpha-diol. Epitestosterone acts as an antiandrogen in various target tissues. The ratio between testosterone/epitestosterone is used to monitor anabolic drug abuse.
