Filter by:Azoospermia is defined as the complete absence of spermatozoa in the ejaculate. Two-thirds of azoospermic patients have non-obstructive azoospermia (NOA); the latter comprises up to 10% of infertile men overall. NOA is an untreatable testicular disorder associated with spermatogenic failure and is the most severe male infertility phenotype. Among the available surgical sperm retrieval techniques, microdissection testicular sperm extraction (micro-TESE) is the procedure of choice due to its high sperm retrieval success rates (SRR), minimal tissue extraction, and low complication rates. Even with the use of micro-TESE, the likelihood of retrieving sperm in patients with NOA remain suboptimal (40% to 60%). Hypogonadism is detected in approximately half of the patients with NOA. Given the role of intratesticular testosterone (ITT) levels for spermatogenesis, some studies have explored the clinical utility of testosterone optimization by medical therapy before sperm retrieval. Moreover, some investigators have hypothesized that the follicle-stimulating hormone (FSH) reset might increase the expression of FSH receptors and improve Sertoli cell function. Hormonal therapy with human chorionic gonadotropin (hCG) has been shown to improve ITT production and decrease FSH levels in patients with NOA. The investigators, therefore, designed an observational cohort study aiming to evaluate whether hormone stimulation with gonadotropins (e.g., hCG alone or combined with FSH) previous to micro-TESE increases sperm retrieval rates in hypogonadal infertile men with NOA, candidates for sperm retrieval. The investigators hypothesize that optimizing ITT production and resetting FSH levels may improve spermatogenesis and successful sperm recovery.
A 38 week dosing trial of lonapegsomatropin, a long-acting growth hormone product, administered once-a-week versus placebo-control. A daily somatropin product arm is also included to assist clinical judgement on the trial results. Approximately 240 adults (males and females) with growth hormone deficiency will be included. Randomization will occur in a 1:1:1 ratio (lonapegsomatropin : placebo : daily somatropin product). This is a global trial that will be conducted in, but not limited to, the United States, Europe, and Asia.
This study will investigate the effects of high-protein, high-fat snacks, specifically Greek yogurt, and peanuts, on satiety, gut hormones, and insulin secretion in overweight and obese women. The hypothesis posited that peanuts will exhibit a more beneficial impact on satiety, gut hormones, and insulin levels compared to Greek yogurt. The two-arm parallel randomized trial will involve 52 participants aged 30 to 40 with a BMI between 25-35 kg/m²,and they will be randomly divided into peanut (n=26) and Greek yogurt (n=26) groups. Pre-snack, BMI and dietary intake will be assessed. Appetite sensations will be gauged using a visual analog scale (VAS) upon arrival, and at 30- and 60-minutes post-snack. Pre- and post-snacking, plasma levels of cholecystokinin (CCK), Peptide Tyrosine-Tyrosine (PYY), Glucagon Like Peptide-1 (GLP-1), Ghrelin (GHRL), and insulin will be analyzed.
This study was performed to determine the pharmacokinetic parameters of vaginal rings that contain DHEA, testosterone, or combinations of both androgens, in comparison to the oral administration of DHEA and the transdermal administration of testosterone.
The purpose of this study is to evaluate the safety and effectiveness of adipose derived mesenchymal stem cells (AD-MSCs) therapy on sexual hormone deficiency in the middle-aged patients
A multicenter, phase 3, long-term extension trial of TransCon hGH administered once-weekly in children with growth hormone deficiency (GHD) who previously participated in a phase 3 TransCon hGH trial. Approximately 300 children (males and females) with GHD will be included. All study participants will receive TransCon hGH. This is a global trial that will be conducted in, but not limited to, the United States, Poland, Bulgaria, Ukraine, Armenia, Russia and Australia.
A 26 week trial of TransCon hGH, a long-acting growth hormone product, administered once-a-week. Approximately 150 children (males and females) with growth hormone deficiency (GHD) will be included. All study participants will receive TransCon hGH. This is a global trial that will be conducted in, but not limited to, the United States, Canada, Australia, and New Zealand.
