The aim of this study is to investigate the markers of bone mineral metabolism in an unconfounded group of patients with hypogonadism and to search for a relationship between endothelial dysfunction and insulin resistance.
The investigators are seeking healthy volunteers and volunteers with reproductive disorders for the study of the role of dynorphin in the reproductive system. Dynorphin is a naturally occurring opioid hormone that is blocked by naloxone. We hypothesize that naloxone, by blocking dynorphin, will stimulate production of gonadotropin-releasing hormone (GnRH) and kisspeptin, two other naturally occurring reproductive hormones.
This study will assess if corifollitropin alfa (MK-8962), when administered in combination with human chorionic gonadotropin (hCG), will increase testicular volume in men with HH who remain azoospermic after treatment with hCG alone. Hypothesis: The lower limit of the 95% confidence interval for the geometric mean increase in testicular volume from Day 1 to Week 52 is greater than one.
The aim of the study is to compare the efficacy and safety of r-hFSH+r-hLH in a 2:1 ratio with human Menopausal Gonadotropin Highly Purified (hMG-HP), in WHO type I anovulation, HH women. This open-label monocentric, randomized comparative trial, to receive the two different standard clinical practice treatments: - 1 vial of Pergoveris: (vial/powder 150 International unit (IU) r-hFSH+ 75IU r-hLH) - 2 vials of Menopur: (vials/powder hMG 75IU). Follicular development were monitored until the protocol hCG requirement is met and a single injection of hCG was administered. Main Outcome Measures were follicular development i.e. follicle ≥ 17 millimeters (mm), pre-ovulatory E2 ≥ 400 picomole/Liter (pmol/L) and mid-luteal phase Progesterone (P4) ≥ 25 nanomole/Liter (nmol/L).
The purpose of this study is to explore the genetic basis of reproductive disorders and cleft lip and/or palate.
The 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.
The goal of this study is to test whether the hormone kisspeptin has the potential to prospectively diagnose adolescents with self-resolving or permanent delayed puberty. Some children with delayed puberty will eventually enter puberty on their own. However, some children with delayed puberty have a permanent condition and require medical treatment to undergo puberty. Right now, there is no reliable diagnostic tool to tell whether a child's delayed puberty will be self-resolving or permanent. The hormone kisspeptin has the potential to prospectively diagnose adolescents with self-resolving or permanent delayed puberty.
The traditional therapy for induction of spermatogenesis in male hypogonadotropic hypogonadism requires both HCG and human menopausal gonadotropin (HMG) or FSH until pregnancy occurs. Because of the high cost of hMG or FSH preparations and poor compliance, the investigators raise a new sequential therapeutic approach which can make the treatment more economic and tolerable. The zinc supplement will be also evaluated in patients in this study. This randomized, parallel, open, and multi-center study will compare the efficacy of traditional therapy with new therapy and evaluate the safety of the new protocol.
Low testosterone production, known clinically as hypogonadism, appears to be common complication of type 2 diabetes, affecting one in three diabetic men. Hypogonadism is known to be associated with decreased muscle mass, increased fat mass, increased inflammation and decreased fertility. In this grant, the investigators propose to study the effects of having low testosterone on 1) insulin sensitivity, the ability of the body to handle glucose 2) fat and muscle mass at specific areas of the body 3) expression of mediators of inflammation in the blood 4) semen quality. This study will compare diabetic men (with or without hypogonadism). This study will also evaluate the effect of treatment with clomiphene (a drug that increases testosterone and sperm production) or testosterone in men with diabetes and hypogonadism. The investigators hope that this project will help us understand the state of hypogonadism in young type 2 diabetic men who are in their peak fertility years and give us insights into treatment of this condition. With the rising prevalence of type 2 diabetes in the young, this project may have implications for public health.
