Active clinical trials for "Hypogonadism"

Patients with infertility often presents alterations at ultrasonographic examination of the testis. These alterations include a much higher incidence of small, multiple, non-palpable hypoechoic micro-nodules that can show internal vascularization. This finding often create alarm and anxiety, because it has to be placed in a differential diagnosis versus low-stage malignant germ cell tumors. Nevertheless, explorative surgery reveal that a consistent number of these lesion are benign, due to Leydig cell hyperplasia or Leydig cell tumours. The purpose of this study is to evaluate the effects of androgen therapy on the size and number of non-palpable hypoechoic micro-nodules in patients with elevated gonadotropin levels.

The Purpose of the study is to determine the effects of Androxal on morning testosterone and reproductive status in men with secondary hypogonadism(confirmed morning Testosterone less than 250 ng/dL), compared to changes with placebo, or Testim (topical testosterone). The effects of Testim versus placebo on reproductive status will also be examined. Study subjects must not be currently using a topical testosterone.

The study will determine the effects of three doses of Androxal(enclomiphene citrate)on morning testosterone versus AndroGel(approved topical treatment)in men with low testosterone (<350 ng/dL)after 6 weeks of continuous dosing.

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 4 weeks in the treatment of hypogonadal men with chronic obstructive pulmonary disease (COPD) that are on oral glucocorticoid therapy.

Hypogonadism (HG) frequently complicates the Metabolic Syndrome (MetS), whether testosterone replacement (TRT) is beneficial has not been clearly ascertained. This study was designed to address the effects of TRT on insulin resistance, body composition and pro-inflammatory status in naïve patients with MetS and HG.

The study was designed to determine if Androxal® would affect sperm parameters (count, concentration, volume) in men with secondary hypogonadism who have been previously treated with topical testosterone.

Testosterone replacement treatment is the most effective way of treating hypogonadism in men. Acrux has a propriety testosterone replacement product- Testosterone MD-Lotion (cutaneous solution), and this study will evaluate the efficacy via pharmacokinetics of various doses of this product. The study will also assess safety of the product.

The purpose of the study is to determine the effect of food with various amounts of fat on the absorption of an oral testosterone undecanoate formulation.

The purpose of this study is to determine whether a higher-than-replacement dose of testosterone and finasteride can be combined to safely increase muscle strength in older men who have a low blood concentration of testosterone.

The combination of testosterone and dutasteride is intended for use in hypogonadal men. This study will evaluate the bioavailability and pharmacokinetics of various doses of testosterone administered with and without dutasteride
