The Effect of Various Amounts of Fat on PK of Oral Testosterone Undecanoate
HypogonadismA Phase 2, open-label, randomized, cross-over, pharmacokinetic study designed to determine the effect of meals of various amounts of fat given immediately prior to dosing on the pharmacokinetics of oral testosterone undecanoate. Approximately 20 hypogonadal subjects will be dosed for a 14 day run-in period. This will be followed by a randomized sequence of five periods over a 6 day confinement period. Subjects will receive a randomly ordered sequence of breakfast meals containing various amounts of fat, fasting, 15 g, 30 g, 45 g and a high fat breakfast consistent Guidance for Industry on Food-Effect Bioavailability and Fed Bioequivalence Studies.
Effect of Varying Testosterone Levels on Insulin Sensitivity in Normal and IHH Men
HypogonadismType 2 diabetes is one of the most common metabolic disorders in the U.S, estimated to affect 16 million Americans. Established risk factors for this disease include obesity, increased waist/hip ratio, high insulin levels in the blood, and insulin resistance. Testosterone may play a role in developing or preventing diabetes, but we do not yet know for sure. The purpose of this research study is to determine if changing testosterone levels in men will result in changes in insulin sensitivity. Information learned form this research study may have important public health implications and may point to new strategies for treating or preventing diabetes.
Studying the Effects of 7 Days of Gonadotropin Releasing Hormone (GnRH) Treatment in Men With Hypogonadism...
Kallmann SyndromeIdiopathic Hypogonadotropic Hypogonadism1 moreMen with Idiopathic Hypogonadotropic Hypogonadism (IHH) lack a hormone called gonadotropin releasing hormone (GnRH). This hormone is important for starting puberty, maintaining testosterone levels, and fertility. The purpose of this study is to research the effects of treating IHH men with GnRH for 7 days.
Reprometabolic Syndrome Mediates Subfertility in Obesity
ObesityInfertility2 moreObesity plays an adverse role at every stage of conception and pregnancy and mounting evidence implicates relative hypogonadotropic hypogonadism, and reduced menstrual cycle hormone secretion as likely contributors to the subfertility phenotype and possible contributors to complications of pregnancy and the developmental origin of adult diseases such as diabetes and cardiovascular disease. This study will be the first comprehensive investigation to tie together the patterns of hyperinsulinemia, hyperlipidemia and inflammation, characteristic of obesity and obesity-caused relative hypogonadotropic hypogonadotropism and its potential adverse reproductive outcomes. The investigators findings will be used to inform a subsequent clinical intervention to optimize reproductive outcomes for obese women and their offspring.
Pharmacokinetics of Testosterone Lotion in the Treatment of Hypogonadal Males
HypogonadismTestosterone replacement treatment is the most effective way of treating hypogonadism in men. Acrux has a proprietry testosterone replacement product - Testosterone-MD Lotion, and this study will evaluate the efficacy and safety of this product.
Evaluation of Furosap in Human Volunteers
HypogonadismThe study evaluates the effect of Fenugreek seed extract (Furosap) in management of symptomatic hypogonadism as fenugreek seed extract is a testosterone booster. Fenugreek seeds extract are known to possess protodioscin and the extract is reported to improve sperm count, sperm morphology and protective effect on male reproductive system. All the participants will receive one capsule (500 mg) of furosap once a day.
Effects of Testosterone on Myocardial Repolarization
HypogonadismChronic Heart FailureThe main of the study is to evaluate the effect of testosterone on ventricular repolarization in patients with mild heart failure, at risk for sudden cardiac death. The electrocardiographic markers studied are QT variability index, the short term variability index.
Extragonadal Effects of hCG on Calcium Homeostasis
HypogonadismCalcium Disorder1 moreA pilot study showed that serum calcium levels and calcium homeostasis change in response to hCG stimulation test. Serum calcium level differed when comparing pretreatment values at baseline with serum levels 72 hours after hCG stimulation in men with gonadal insufficiency referred for this stimulation test. Now we want to investigate whether this change in calcium is due to renal loss or other mechanisms and how the classical regulators of calcium homeostasis respond to hCG in men with impaired gonadal function compared with men having normal gonadal function. Moreover, the observed change in serum calcium implies that hCG also changes Phosphate, PTH and calcitonin and this will be clarified with this study
Assessment of the Effects of Enclomiphene Citrate on Bone Mineral Density in Men With Secondary...
Effect of Treatment on Bone Mineral DensityTo determine the effects of 12 months of treatment with Androxal on bone mineral density in men with secondary hypogonadism.
Elucidating Kisspeptin Physiology by Blocking Kisspeptin Signaling
Hypogonadotropic HypogonadismHealthy Postmenopausal Women1 moreThe investigators are looking for subjects to complete a study on the role of kisspeptin in the reproductive system. Kisspeptin is a naturally occurring hormone in humans that tells the body to produce other reproductive hormones. However, giving someone a continued amount of kisspeptin over a period of time can have the opposite effect and tell the body to, for a short time, stop making hormones needed for reproduction. By giving 24-hour infusions of kisspeptin, the investigators hope to learn more about the role kisspeptin has in the way bodies function normally and the role it has in conditions that affect the reproductive system.
