This review discusses steroid cell tumors of the ovary, their hormone production, symptoms, and evaluation, emphasizing surgery as the key treatment approach; it reports no new clinical results.

This study found that elevated luteinizing hormone levels were significantly associated with female pattern hair loss, and implicated LH/LHR signaling in the aging and damage of hair follicles.

In this case report, an embryonal cell carcinoma of the testicle was associated with polycythemia and markedly elevated hormone levels without secondary sexual characteristics, which were restored after treatment.

This case report highlights the importance of considering an ovarian steroid cell tumor diagnosis in young women with increased testosterone after ruling out polycystic ovarian syndrome.

This study found that nestin-expressing cells in the hair follicle bulge exhibit multipotent stem cell-like properties and can generate neural cells both in vitro and in vivo.

In this case study, researchers observed a 5.8-year-old male with peripheral precocious puberty due to a germ cell tumor, marked by elevated human chorionic gonadotropin levels. Treatment normalized hormone levels and arrested the puberty progression, highlighting melatonin's potential role in transitions to central precocious puberty.

This case report suggests that ovarian steroid cell tumors should be considered in postmenopausal women with hirsutism and elevated testosterone, with surgery being effective in resolving symptoms and preventing recurrence.

This review discusses nitric oxide's physiological roles and the development of strategies for delivering it exogenously, without presenting new clinical results.

This case report underlines the importance of considering alternative diagnoses like ovarian steroid cell tumors in adolescent females with PCOS-like symptoms when standard treatments fail, highlighting the need for thorough evaluation and early intervention.

This review discusses the complex effects of testosterone on the brain, emphasizing sex differences, and reports no clinical results; the authors highlight the inconsistencies in current study findings.

This review discusses how various nutrients, such as flavonoids, probiotics, and omega-3 fatty acids, may support brain health by targeting stress-related pathways, potentially offering protective effects against neurodegenerative and psychiatric disorders through their roles in oxidative stress reduction and neuroinflammation regulation.

This narrative review discusses the mixed and evolving evidence regarding glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and their influence on erectile dysfunction in men with type 2 diabetes and obesity, highlighting potential benefits and concerns yet to be clarified.

This study found that Origanum vulgare extract improved testicular structure and function in mice against finasteride-induced damage by enhancing antioxidant defense and modulating gene expression related to apoptosis.

Sea holly extract may help reduce hair loss.

This review discusses the relevance of human androgen receptor action in sports doping and examines the potential of cell-based biological assays for detecting androgenic anabolic steroid use, without presenting new research findings.

This article reviews how various medications, such as antihypertensives, chemotherapy, and hormonal contraceptives, are associated with negative effects on sexual desire and function but reports no new clinical results.

This study indicated that while testosterone replacement in older men with low testosterone increases muscle mass and strength and reduces fat, its effects on physical function, disability, falls, or fractures remain unclear.

This study found that finasteride treatment of male rats led to changes in their male offspring's testicular gene expression, potentially affecting sperm function in response to odorant-like signals.

This study found that previously undescribed WNT10A mutations are a prominent cause of various forms of ectodermal dysplasia, including OODD and Schöpf-Schulz-Passarge syndrome, with gender-specific phenotypic effects noted.

In this review, researchers highlighted that natural polyphenolics like flavonoids and resveratrol may help enhance testosterone production in aging males by boosting the expression of the Star gene in Leydig cells, potentially preventing age-related degenerative conditions linked to testosterone insufficiency.

This review discusses the potential impact of COVID-19 on the male reproductive system and highlights unanswered questions regarding its mechanisms and implications for men's health and fertility, reporting no new clinical results.

This case study describes a testosterone-secreting adrenal adenoma in a 55-year-old woman, highlighting the presence of Reinke's crystalloids, suggesting that Leydig cells may play a role in such tumors.

This chapter reviews the properties and applications of epidermal stem cells in skin tissue engineering and transplantation but reports no new experimental results.

This review discusses the role of stem cells and tissue engineering in regeneration and transplantation, emphasizing the need for advanced technologies to improve treatments for injuries and disabilities, but reports no new results.

This review outlines the role of testosterone in male sexual development and its therapeutic use for male hypogonadism, covering its biosynthesis, secretion, metabolism, and various biological actions, but does not report specific study results.

In this study, low-dose BPA was associated with induced prostatic hyperplasia in rats, potentially mediated by COX-2 and L-PGDS through pathways involving cell proliferation and apoptosis.

In this study, young albino rats whose mothers received high doses of rosemary extract during lactation showed negative health effects, including inhibited weight gain and organ damage, suggesting potential teratogenicity of rosemary extract when used in such conditions.

This review evaluates the anti-aging properties of TSG from He shou wu, finding it may protect against age-related diseases through multiple mechanisms, though further research is needed for clinical application.

This study found that high prepubertal and pubertal androgen levels, originating from both adrenal and gonadal secretion, were negatively associated with adult height outcomes in males with Silver-Russell syndrome.

In this study, Quercetin-loaded black seed oil nanoemulsion effectively mitigated testosterone-induced testicular oxidative stress and inflammation in rats undergoing exercise and restraint stress, with improved antioxidant levels and reduced inflammatory markers compared to other treatment groups.
