This study is being done to learn how the male hormone , testosterone, affects pituitary hormones in younger and older men. The pituitary is a gland in the brain that secretes hormones, some of which normally control growth and fertility.
Low testosterone may be responsible for "soft" erections in men. The purpose of our study is to see whether the daily application of a testosterone gel to raise testosterone levels will also increase the "hardness" of a man's erection.
The purpose of this study is to evaluate the response of a treatment with testosterone undecanoate and determine the levels of total and free testosterone in hypogonadal patients with erectile dysfunction.
The objective of the study is to assess and compare the preliminary efficacy, safety and tolerability of fispemifene 300 mg and placebo given once daily for 8 weeks in the treatment of hypogonadal men with erectile dysfunction (ED) unresponsive to PDE5 inhibitors.
This is an observational study with a drug called Nebido, a new testosterone replacement therapy, which is available for the treatment of male hypogonadism. The benefit and safety of Nebido have already been thoroughly evaluated through well controlled clinical trials. The main purpose of this observational study is to confirm the established safety profile of Nebido in daily clinical practice.
The combination of testosterone and dutasteride is intended for use in hypogonadal men. This study will evaluate the bioavailability and pharmacokinetics of various doses of testosterone administered with and without dutasteride
The combination of testosterone and dutasteride is intended for use in hypogonadal men. This study will evaluate the effect of 28-day repeat dosing of this combination with varying BID doses of testosterone (T), in combination with a fixed BID dose of dutasteride (D), as well as a testosterone alone arm, on T and D levels in the blood. The rationale is to look for the effects of each compound on the other, and to look for any safety problems that may result when the 2 drugs are given together.
Treatment with testosterone can improve performance on tests of spatial ability in men with low testosterone levels and Alzheimer's disease. Improved performance on these tests may mean an improved ability to get around in one's environment without getting lost or injured. This could have a positive impact on both patients and those who care for them. We will investigate what areas of the brain are involved in these improvements in spatial ability. This will be done using a PET scan, which creates a 3-dimensional image of the brain that can allow us to see how the brain functions.
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.
