Filter by:This study aims to explore whether men with low testosterone levels, due to altered brain regulation of male hormone function, who have been previously treated with testosterone, respond as well as men who have not been so treated to clomiphene citrate, an agent commonly used for female infertility that has been shown to improve male hormone secretion in some cases.
This study will evaluate if testosterone solution can raise testosterone hormone levels into the normal range after treatment for up to 9 Weeks, in those participants with a documented history of subtherapeutic levels [total testosterone <300 nanograms per deciliter (ng/dL)] when previously treated with a topical testosterone gel.
Relative Bioavailability and Safety comparison of 3 formulations of Testosterone Enanthate.
The purpose of this randomized controlled clinical trial is to evaluate the effects of clomiphene citrate compared to placebo (substance without active medication) in men who are taking pain medication (opioids) for chronic pain conditions and who have low blood testosterone levels. The condition of men having low testosterone with long-term pain medication (opioid) usage is called opioid-induced androgen deficiency (OPIAD). Low testosterone can be caused by pain medication effects on part of the brain (hypothalamic-pituitary axis) which ultimately result in decreased testosterone production by the testes. Typical symptoms of low testosterone (hypogonadism) may include decreased muscle mass, increased fat, osteoporosis, anemia, erectile dysfunction, delayed ejaculation. In addition, men with low testosterone may experience decreased attention, and decreased libido, fatigue, and depressed mood. Few studies have looked at hormonal changes caused by long-term opioid usage in men. Clomiphene citrate, a selective estrogen receptor modulator (SERM) oral medication which inhibits estrogen effects (feedback) on the brain, has been identified by prior studies to raise testosterone in men with low testosterone (due to reasons other than chronic pain medication). Clomiphene citrate is also known to lead to increased sperm production in men with low testosterone unlike testosterone topical or injection medications. Although clomiphene citrate has been studied in hypogonadal men with beneficial outcomes and minimal side effects, no group has previously studied clomiphene citrate as treatment in patients with OPIAD.
This study is designed to develop an effective treatment intervention for chronic pain, symptomatic hypogonadism, and opioid addiction
The main purpose of this study is to evaluate if testosterone solution can raise testosterone hormone levels into the normal range, and also improve levels of sexual arousal, interest and drive and/or energy level, in men with low testosterone and decreased sexual arousal, interest and drive and/or decreased energy. The study will last about 16 weeks, followed by an optional 24 week open label treatment phase to investigate the long term safety of testosterone solution.
The purpose of the study is to determine if oral testosterone undecanoate is effective and safe in the treatment of low testosterone in men.
The aim of the present study was to demonstrate the RBP4 levels, association of RBP4 with insulin resistance and influence of testosterone treatment on this cytokine in patients with idiopathic hypogonadotropic hypogonadism.
Low total testosterone (TT) is present in about 30% of men aged >60 years and in up to 7% of younger men. Male hypogonadism is associated with metabolic and cardiovascular diseases as well as with increased mortality. There is evidence showing a relationship of TT with vitamin D in men. We aim at evaluating the effect of vitamin D supplementation on TT and metabolic parameters in hypogonadal men. We will study the effects of 20,000 IU vitamin D weekly in a 12 wk randomized, double-blind, placebo-controlled trial in 100 men with TT <3.0 ng/ml and 25-hydroxyvitamin D (25(OH)D) <30 ng/ml (patients) as well as in 100 men with TT ≥3.0 ng/ml and 25(OH)D <30 ng/ml (controls). Vitamin D supplementation might be a safe therapeutic approach improving TT levels as well as metabolic parameters in hypogonadal men. Further the effects of vitamin D on androgens will be evaluated in eugonadal men.
The purpose of ZA-302 is to determine the effects of Androxal on morning testosterone and reproductive status in younger overweight men with acquired hypogonadotropic hypogonadism (confirmed morning T<300 ng/dL) and normal sperm concentration, compared to changes with placebo. Subjects must not have previously been treated with testosterone products within the last 6 months.
