215 Clinical Trials for Various Conditions
Men 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.
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.
The investigators are doing this research study to look at the relationship between testosterone (the main sex hormone in men) and insulin (the hormone that controls blood sugar levels) in men with Idiopathic Hypogonadotropic Hypogonadism (IHH). The investigators hypothesize that normalizing testosterone levels in men with IHH enhances insulin sensitivity, reduces visceral fat, increases lean body mass, and improves the lipid profile.
The purpose of the study is to examine how Kallmann syndrome (KS) and idiopathic hypogonadotropic hypogonadism (IHH) affect reproductive hormones. These disorders are caused by a defect in Gonadotropin Releasing Hormone (GnRH) secretion. GnRH is a hormone released by a small gland in the brain called the hypothalamus. When GnRH is released, it signals another gland in the brain, the pituitary, to secrete the reproductive hormones that influence sex hormone (testosterone, estrogen) levels and gamete (sperm, egg cell) production. This study involves a detailed evaluation and 24-48 hours stay at the hospital. In this study, males and females ages 16 and older with IHH have a detailed evaluation which involves an overnight study at the hospital. Some men (18 years and older) may continue on to receive treatment with pulsatile GnRH. This treatment replaces the hormone which is absent in IHH and results in normalized testosterone and typically is effective in developing fertility.
Sponsor has decided to discontinue Luveris® in the United States (US) due to level of customer demand for this product, and not due to any efficacy or safety concerns.
This is a 52-week open label single arm study to investigate the effects of XYOSTED, as testosterone replacement therapy, on adolescent males with either primary or secondary hypogonadism. The study aims to determine the effectiveness of XYOSTED measured by continuation or induction of puberty in addition to XYOSTED dosage, safety and testosterone levels.
It has been known that both estrogen and testosterone are the major sex steroids regulating bone metabolism and other physiological changes in both male and female, respectively. In postmenopausal women, osteoporosis is a major concern secondary to the lack of estrogen. These patients also experience a number of physiological changes that affect their life permanently to include hot flashes, irritability, difficulty concentrating, depression and mental confusion. In hypogonadal men, testosterone deficiency could lead to higher prevalence of depression, osteoporosis, fracture and frailty. Given the new military policy starting to support treatment for gender identity dysphoria military personnel, the number of transgender patients in our Endocrinology clinic has been slowly increasing over the past several months. These patients will require either testosterone replacement therapy or estrogen therapy to achieve their desired sexual characteristics. However, as mentioned above, the lack of estrogen or testosterone in female and male, respectively, could cause several issue in their body composition, cognitive function and quality of life. We designed this prospective case-control study to include patients with hypogonadism and the transgendered populations to learn about the long-term effects of these hormonal replacement therapies on bone density, fractures, memory/cognitive function and quality of life. This is a repetitive measures study taken at baseline, 6-months, and 12-months for three groups consisting of at least 75 subjects. The study will involve 3 arms, i.e. Group 1 primary/secondary untreated hypogonadism, Group 2 male-to female (MTF), and Group 3 female-to-male (FTM) participants that are planning to start hormone replacement therapy as per standard clinical guidelines.
This study evaluates 7 Tesla (T) magnetic resonance imaging (MRI) in observing changes in the brain (neuroimaging) in testicular cancer patients who have decreased testosterone (hypogonadism) and are on testosterone (androgen) replacement therapy. Symptoms of hypogonadism can include fatigue, weakness, loss of libido, depression, poor concentration and erectile dysfunction. Some patients experience mental changes after diagnosis and treatment. There is some evidence that hypogonadism produces structural changes in the brain. The 7T MRI uses radio waves and a very powerful magnet linked to a computer to create detailed pictures of areas inside the body. This study may help researchers learn if 7T MRI can produce better images to assess the changes in the brain structure of testicular patients with hypogonadism and on androgen replacement therapy (ART).
The goal of this study is to evaluate the effects of opioid antagonists on the hypothalamic-pituitary-gonadal axis in subjects with idiopathic hypogonadotropic hypogonadism (HH).
The aim of this trial is to evaluate whether testosterone replacement results in greater improvement in pain perception, pain tolerance, sexual function, fatigue, and quality of life when compared with placebo in men with chronic spinal pain treated with opioids who have opioid-induced hypogonadism (low testosterone).
The goal of this study is to develop novel treatments for patients with a condition called hypogonadotropic hypogonadism (HH) through the use of exogenous kisspeptin.
Testosterone is the principal androgen produced by the male testes. Male Hypogonadism is the result of inadequate production of testosterone by the Leydig cells of the testes and is reflected by total serum concentrations of testosterone of \< 300 nanograms (ng)/deciliters (dL), with no discernible diurnal pattern. The etiology of hypogonadism may be primary or secondary. The treatment of males with primary, and in some cases, secondary hypogonadism includes administration of testosterone. Testim® and Fortesta® are topical gels that when applied daily help to increase the total testosterone levels in the blood through skin absorption. Aveed® is an injectable form of testosterone treatment and participants randomized to this treatment arm will receive 3 injections over the course of 16 weeks. This study is designed to evaluate the effect on blood pressure of approved testosterone products (Testim®, Fortesta®, and Aveed®) after 16 weeks of therapy using 24-hour ambulatory blood pressure to reveal shifts in blood pressure levels.
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.
Low testosterone and diabetes mellitus are each associated with increased risk for fractures. Men with diabetes mellitus are commonly found to have low testosterone as well. Testosterone has been shown to improve the bone health of patients with low testosterone but has not been tested in patients who also have diabetes mellitus in addition to low testosterone. To date, there is no treatment that is specifically recommended for bone disease among patients with diabetes. This study will evaluate the effect of testosterone on the bone health of male Veterans who have both diabetes and low testosterone, both of which are highly prevalent in this subset of the population.
The investigators have preliminary data suggesting that obese patients with hypogonadotropic hypogonadism (HHG) have minimal benefit from testosterone therapy likely because of its conversion to estradiol by the abundant aromatase enzyme in the adipocytes. The increased conversion of androgens into estrogens in obese men results in a negative feedback of high estradiol levels on hypothalamus and pituitary, inhibiting the production of gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH) and follicle stimulating hormone (FSH) and, as a consequence, of testosterone by the testis. Testosterone administration could increase estradiol production, further promoting the inhibitory feedback to the hypothalamic-pituitary-gonadal axis. Although weight loss from lifestyle modification has been shown to reduce estradiol and increase testosterone levels, the effect is at best modest and weight regain results in recurrence of hypogonadism. The use of aromatase inhibitors, in combination with weight loss, could be an effective alternative strategy due to its action at the pathophysiology of the disease. Intervention Subjects (body mass index of ≥35, testosterone \<300 ng/dl) will be randomized to the active (anastrozole) or control (placebo) group. Anastrozole 1 mg tablet / day will be self-administered with or without food, at around the same time every day (active group); placebo 1 tablet/day with or without food to take at around the same time every day (control group). The study duration will be 12 months. Both groups will undergo lifestyle intervention consisting of diet and supervised exercise program. Target weight loss will be at least 10% of baseline body weight during the intervention. Subjects will attend weekly group behavior modification sessions which will last \~75-90 min for the first 3 months and decreased to every two weeks from 3 to 12 months. Subjects will attend supervised research center-based exercise sessions during the first 6 months followed by community fitness center-based sessions during the next 6 months for at least 2 d/wk, with recording of home-based exercises for the other 2-4 days/week.
