This clinical trial investigated the effects of human calcitonin on growth hormone (GH) secretion in healthy male subjects. The study found that calcitonin suppressed spontaneous GH surges and reduced GH responses to both insulin-induced hypoglycemia and growth hormone-releasing hormone (GHRH). Additionally, calcitonin led to a transient increase in plasma prolactin
This observational study, titled “Decrease in glutathione may be involved in pathogenesis of acne vulgaris” (Journal of Cosmetic Dermatology, 2011, PMID: 21896138), investigated the relationship between glutathione (GSH) levels and acne. Researchers compared stratum corneum samples from acne-affected facial skin, unaffected facial areas, and upper arms of acne patients, with
This review consolidates current research on L-Carnitine supplementation and its potential benefits for male fertility, incorporating in vitro, animal, and clinical studies. L-Carnitine has been shown to improve sperm motility, morphology, and concentration while regulating hormone levels and reducing oxidative stress, which may enhance fertility outcomes. These effects are attributed
Bremelanotide, a melanocortin receptor agonist, has been FDA-approved as an as-needed treatment for hypoactive sexual desire disorder (HSDD) in premenopausal women. Clinical trials demonstrated statistically significant improvements in sexual desire and reductions in distress related to low libido, though the overall clinical benefit was considered modest. Administered via subcutaneous injection
A single-blind, placebo-controlled crossover study examined the effects of dehydroepiandrosterone (DHEA) administration on 24-hour plasma cortisol levels in healthy older adults. Participants received either a placebo or 200 mg of oral DHEA daily for 15 days. The study found that DHEA administration significantly reduced plasma cortisol concentrations, with a more
The article “The influence of estrogen on skeletal muscle: sex matters” reviews the role of estrogen in skeletal muscle function and its sex-specific effects. It discusses how estrogen can improve muscle contractile properties, reduce muscle damage after exercise, and modulate inflammation. Animal studies suggest estrogen has protective effects on muscle
This article explores the bidirectional relationship between estrogen and the gut microbiome, emphasizing how gut bacteria influence estrogen metabolism and, in turn, how estrogen affects microbiome composition. This interaction plays a crucial role in various physiological processes, including metabolic health, immune function, and neurological disorders. The findings suggest that understanding
