Active clinical trials for "Hypogonadism"

The purpose of this study is to determine which dose, if any, results in testosterone levels within the normal range for men.

Estrogen is necessary for feminization during puberty and to decrease bone resorption, the latter critical for the achievement of peak bone mass and normal bone health in the female. The practicing pediatric endocrinologist often faces the dilemma of how to best feminize girls with hypogonadism (lack of estrogen), manifested as delayed or arrested puberty, due to disorders of the brain or the ovaries. We propose a series of studies to address which type, dose, and route of delivery of estrogen are suitable choices in feminizing and sustaining estrogen concentrations in adolescent girls with Turner syndrome. To accomplish this we will study girls/young woman between the ages of 13 to 20 with Turner Syndrome in 2 protocols. In Protocol # 1 we will study 24 girls with TS, they will receive 3 different estrogen preparations, either by mouth or via a patch for a total of 6 weeks. They will come to the clinical research center for blood draws after 2 wks of taking the estrogen. With this study, we hope to learn how the body responds to estrogen differently, depending on the form estrogen is given and how high, estrogen levels gets in the blood in these girls with Turner Syndrome. We will be comparing these patients estrogen levels to girls that menstruate normally and do not have Turner Syndrome. In Protocol #2, 40 patients with TS will be recruited; these patients will take estrogen for 1 year, either by mouth or via a patch. Patients will come to the lab for blood drawn in 7 occasions and we will measure estrogen levels as well as other hormones and lipid levels. We will also perform a Dual-energy X-ray absorptiometry (DXA) study (like an X ray) to assess body composition and bone mineralization. We will adjust doses based on the estrogen levels we find. With this study we hope to learn how estrogen affects body composition, i.e., the amount of fat vs. muscle, and how different forms of estrogen affect blood cholesterol and other hormones. This study will allow us to understand better how to best replace young woman with Turner Syndrome with estrogen.

The purpose of this pharmacokinetic study is to determine whether oral testosterone (T) ester formulations can be used effectively to treat men with low testosterone.

This is an open-label study of a single and repeated application of three dose levels of topical testosterone in hypogonadal males with morning serum testosterone concentrations < 297 ng/dL.

Male hypogonadism, a disorder associated with testosterone deficiency, is frequently seen in clinical practice and has significant effects on patient wellbeing. The purpose of this study is to investigate the efficacy and safety of ARD-0403 as a testosterone replacement therapy in testosterone deficient men.

The purpose of this study is to evaluate the response of a treatment with testosterone undecanoate and determine the levels of total and free testosterone in hypogonadal patients with erectile dysfunction.

The objective of the study is to assess and compare the preliminary efficacy, safety and tolerability of fispemifene 300 mg and placebo given once daily for 8 weeks in the treatment of hypogonadal men with erectile dysfunction (ED) unresponsive to PDE5 inhibitors.

This study aims to determine whether testosterone replacement improves insulin sensitivity in non-obese men with low testosterone and the metabolic syndrome. The metabolic syndrome includes three of the following five conditions, 1) an elevated blood pressure (greater than 130/85), 2) a triglyceride level greater than 150 mg/dl, 3) an HDL-cholesterol less than 40 mg/dl, 4) glucose levels greater than 100 mg/dl, and 5) a waist measurement greater than 40 inches.

The purpose of this study is to determine whether one or more fispemifene dose regimens are more effective than placebo in the treatment of hypogonadism in older men.

The purpose of this research study is to determine whether the combination of the male hormone testosterone [T] in gel form and the oral drug dutasteride [D], used to shrink large prostate glands can safely reduce the size of the prostate gland and symptoms of prostate enlargement (called benign prostatic hyperplasia [BPH]) compared to T treatment alone in men with low testosterone (called hypogonadism).
