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.
The goal of this clinical trial is to evaluate three doses of the drug leflutrozole on improvement of semen quality in men with hypogonadotropic hypogonadism, a condition that affects hormone levels and fertility. It will also study the safety of leflutrozole. The main questions it aims to answer are: * Does leflutrozole improve semen quality? * What medical problems do participants experience when taking leflutrozole? Researchers will compare leflutrozole to a placebo (a look-alike substance that contains no drug). Participants will: * Take leflutrozole or a placebo orally once a week for 16 weeks. * Visit the clinic every 4 weeks for checkups and tests. * Provide semen samples to measure changes in semen quality. * Have their blood tested to measure hormone levels and ensure safety. * Be monitored for any side effects.
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.
The goal of this study is to evaluate the effects of opioid antagonists on the hypothalamic-pituitary-gonadal axis in subjects with 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.
The purpose of this study is to assess the bioequivalence of Test and Reference in healthy downregulated male participants. This is a 2-sequence, 2-period study using the following treatment sequences across Study Periods 1 and 2. At the end of the first Downregulation period (DR1), eligible participants will be randomly assigned to 1 of the 2 treatment sequences: Sequence 1: Test - Reference Sequence 2: Reference - Test Where, Test = follitropin alfa (solution for injection in prefilled pen), and Reference = follitropin alfa (powder and diluent for solution for injection in vial). The total duration of the study will be up to approximately 9 weeks.
Background: Endocrine disorders occur when the glands that make hormones do not work properly. Hormones levels that are too high or too low can cause problems such as late or early puberty, irregular periods, and infertility. Environmental factors - including pollution; chemical exposure at home and work; foods; medicines; and sleep habits - may cause problems with the endocrine and reproductive systems. Objective: To learn how environmental factors may affect the endocrine and reproductive systems. Eligibility: Males or females, referring to sex assigned at birth, aged 8 years and older; they must have hypogonadism, infertility, or other reproductive disorders. Design: Adult participants will have 4 to 5 visits in 5 years. Children may have up to 12 visits; they may remain in the study up to the age of 23. Most visits will be less than 3 hours. Participants will be screened. They will have a physical exam. They will have blood and urine tests. They will complete questionnaires; they will answer questions about their diet, health, and other topics. Some may be referred for additional tests, such as imaging scans and semen analysis. Specific tests conducted during study visits will vary, depending on the participant s diagnosis. In addition to repeated blood and urine tests, these may include: Body composition measure: Participants will sit in a pod-shaped machine for about 6 minutes. The machines measures the air inside the capsule to record body fat and breathing volume. Resting energy expenditure test: Participants will lie down with a clear dome placed over their head. They will breathe quietly for 30 minutes. This test measures the number of calories their body burns at rest. ...
This phase I trial investigates the safety of testosterone replacement therapy around the time of major urologic surgery (perioperative) in order to improve quality of life and post-operative outcomes such as decreased length of hospital stay, complications, and mortality in patients with low testosterone levels. Studies have demonstrated that patients undergoing testosterone replacement therapy have increased lean body mass, decreased fat mass and have improved physical function. Testosterone replacement therapy can also stimulate bone formation and may decrease the risk of fracture. Information from this trial may be used to support the incorporation of testosterone level testing and testosterone replacement into the perioperative treatment decision-making process.
This is a large randomized, double-blind, placebo-controlled trial to determine the efficacy of testosterone replacement on cancer-related fatigue in older men with solid or hematologic (blood) cancer who report fatigue and have low testosterone levels.
