Active clinical trials for "Hypogonadism"

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).

Male hypogonadism is a clinical situation characterized by a low serum testosterone level in combination with a diversity of symptoms and signs such as reduced libido and vitality, decreased muscle mass, increased fat mass and depression. Similar symptoms in combination with subnormal testosterone levels are seen in some elderly men. Low testosterone levels are associated with known cardiovascular risk factors, and men with diabetes and stroke have lower testosterone levels than healthy men. Even though several publications have suggested that testosterone treatment in hypogonadal men may have beneficial effects, it is still uncertain if testosterone substitution in the aging man is indicated. Despite this uncertainty the sale of testosterone has increased enormously the last few years. We hypothesize that older men with subnormal testosterone levels have a varying degree of dysfunction/symptoms both physically and mentally, and that these dysfunction/symptoms can be improved with testosterone treatment.

RATIONALE: The body's response to one injection of leuprolide may provide more information than the standard test for gonadotropin deficiency in determining whether the cause of gonadotropin deficiency is related to the hypothalamus or the pituitary gland. PURPOSE: Randomized double-blinded clinical trial to study the effectiveness of leuprolide in determining the cause of gonadotropin deficiency.

DITEST is an oral formulation of native testosterone for the treatment of androgen deficiency in men. The study was a Phase 1 clinical study in hypogonadal men, defined according to FDA and Endocrine Society Guidelines, designed to evaluate the pharmacokinetic (PK) characteristics of DITEST, and to assess the safety and tolerability of DITEST in the target population.

Aim of the study was to investigate the effects of testosterone replacement therapy on components of metabolic syndrome, vascular function and morphology, grade of non-alcoholic fatty liver disease (NAFLD), bone mineral density (BMD) and health-related quality of life.

A clinical trial to evaluate the pharmacokinetic profiles and safety of CKD-845.

To compare the effects on body composition and muscle strengthof 54-weeks treatment with of testosterone undecanoate combined with placebo or with the 5a-reductase inhibitor dutasteride

Hypogonadism is an endocrine disorder characterized by absent or deficient testosterone levels along with signs and symptoms of androgen deficiency, including delayed development or regression of sexual characteristics, impaired sexual function and sense of well-being, depressed mood, decreased muscle strength associated with loss of muscle mass and reduced bone mineral density. AndroGel 1.62% has demonstrated its ability to increase total testosterone levels in the blood by absorption of testosterone through the skin when applied topically. This study evaluated the effect of AndroGel 1.62% on systolic blood pressure using ambulatory blood pressure monitoring in hypogonadal men who used testosterone replacement therapy. AndroGel 1.62% is a drug used for the treatment of hypogonadism, which is associated with low or no testosterone. This was an open-label study which means that both the study doctor and study participants knew what drug and what dose is being used. All participants in this study were in the same group, called a treatment arm. Adult male participants with hypogonadism were enrolled and received AndroGel 1.62%. This was a multi-center study with 190 participants enrolled (initially planned) in approximately 45 sites in the United States to yield 171 subjects in the per protocol (PP) population. A blinded sample size re-estimation (BSSR) was performed when around 70% of the planned subjects in the PP population had completed the end of treatment visit. Sample size was increased at BSSR and 246 participants were actually enrolled. Participants received daily topical gel doses of AndroGel 1.62% for approximately 16 weeks. There may have been a higher burden for participants in this study compared to standard of care. Participants attended 8 study visits during the course of the study at a hospital or clinic and received 2 study phone calls. The effect of the treatment was checked by medical assessments, blood tests (including pharmacokinetic sampling), and 24-hour blood pressure monitors.

Although much is known about the microenvironment of the gut and the vagina, very little has been published on the microenvironment of the seminal plasma. The seminal plasma is the support fluid for sperm, providing nutrients, facilitating sperm transit to the uterus, and promoting fertilization. It is a rich area of research for markers of fertility and treatment targets. The investigators hypothesize that (1) there are significant populations of seminal microorganisms associated with seminal leukocyte counts well below the WHO's cutoff for pyospermia (1 million/mL) that were not previously detected by traditional culturing methods, and (2) there are pathologic populations of bacteria within the gut and semen microbiome which negatively impact overall fertility, by directly or indirectly impairing hormone status. Participants will be recruited from the Male Fertility practice at the University of Illinois-Chicago (UIC). All participants will have infertility, diagnosed as an inability to conceive pregnancy after 12 months of unprotected intercourse. The normal evaluation of these participants is to obtain at least one semen analysis and bloodwork investigating their endocrine profile: total testosterone, estradiol, sex hormone binding globulin (SHBG), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and albumin. Semen volume is typically >1 mL, and <0.2 mL is typically used for the semen analysis. If over 1 million/mL round cells are identified, then a Papanicolaou stain would be performed to identify leukocytes. In this study, any semen demonstrated to have round cells would undergo Papanicolaou staining. A portion of the remaining semen, which would typically be discarded, will be sent for microbiome analysis. Secondly, as part of routine care, fertility patients may be started on medications to increase endogenous testosterone (i.e.: clomiphene citrate, anastrozole, etc). Participants started on medications will also be asked to submit a rectal swab for gut microbiome analysis. Routine care is to monitor the hormonal and testicular response with periodic endocrine blood panels and semen analyses; rectal swabs will be requested at these follow-up intervals also. The control group for both hypotheses will be men with clinical infertility with normal semen analyses and hormone profiles.

The purpose of this study is to evaluate the efficacy of testosterone replacement therapy in men with low testosterone due to opioid treatment on body composition, the haemostatic system, glucose metabolism, muscle function, pain sensitivity, pain modulation, lipids, sexual function and quality of life. Male patients on opioids for non-malignant diseases aged 18-59 years diagnosed with hypogonadotrophic hypogonadism, referred from day hospitals and outpatient populations. 40 patients are randomized to either testosterone undecanoate i.m. or placebo i.m., i.e. 20 patients per arm A double blinded randomized placebo controlled trial
