This study found that increased serum A4A levels were associated with more severe polycystic ovary syndrome phenotypes and could be a useful marker for biochemical hyperandrogenemia.

This review discusses the pathophysiology, genetics, and management of nonclassic congenital adrenal hyperplasia, noting subfertility and hormonal issues without providing new clinical results.

This case report describes a 77-year-old woman with female pattern hair loss and elevated testosterone levels, who showed no improvement with minoxidil and lacked adrenal tumors on imaging.

This case report details a diagnostic challenge in a postmenopausal woman with severe hyperandrogenism where distinguishing between adrenal and ovarian causes was complicated by elevated 17-OH Progesterone and asymmetric ovarian enlargement; pending surgical pathology is expected to guide further management.

This study found that in dogs with alopecia, certain steroid hormone levels were elevated, particularly progesterone, but not all hormone abnormalities were consistent across breeds, suggesting the need for breed-specific evaluation.

This study found no correlation between clinical signs and sex steroid levels in ferrets with hyperadrenocorticism and noted that androstenedione was elevated in many cases.

In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

This case study reports an Asian female with congenital adrenal hyperplasia presenting atypically with polymenorrhagia, who showed improvement with oral dexamethasone, despite no change in hirsutism or clitoromegaly.

In this study, a dog with alopecia and a Sertoli cell tumor showed hyperprogesteronemia, and its hair regrew after castration, with progesterone levels reducing toward normal.

This study found that wolves in heavily hunted areas of Canada's tundra–taiga exhibited higher levels of stress and reproductive hormones, indicating social instability and increased reproductive effort due to human-caused mortality.

In this case study, a 55-year-old woman with androgenetic alopecia was ultimately diagnosed with hepatic cortisone reductase deficiency after initially suspected 21-hydroxylase deficiency was ruled out.

This study found that stimulation with certain neurotransmitters and hormones suggests the involvement of 5α-reduced neurosteroids in glial cell differentiation in rat C6 glioma cells.

In this study, adolescents with depressive symptoms were found to have higher urinary excretion rates of certain steroid metabolites, including corticosterone and adrenal hormones, and a specific metabolite ratio was identified as a potential biomarker for distinguishing these patients from healthy controls.

This study found that while rat models treated with letrozole and dihydrotestosterone exhibit altered sterol, leukotriene, and steroid hormone profiles similar to human PCOS, significant differences remain.

In a clinical case study, researchers identified adrenocortical adenoma as the cause of hyperandrogenism syndrome in a preschool-aged girl, following a comprehensive diagnostic process and successful surgical intervention to remove the tumor, leading to positive clinical improvements.

This report describes a case of HAIR-AN syndrome in a young woman, characterized by acanthosis nigricans, insulin resistance, and polycystic ovaries, highlighting its rarity and multisystem nature.

This review discusses the pathophysiology, molecular genetics, and management of non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency, with no new clinical findings reported.

This study reports that transdermal exposure to owners' topical hormone replacement therapy caused alopecia in six dogs, but the condition resolved after the therapy was discontinued.

This study found that systemic testosterone exposure in transgender individuals with XX genotype alters skin biology, increasing androgen and estrogen receptor-positive cells, collagen density, and fibronectin expression while reducing immune cells, which could affect surgical outcomes by promoting a male skin phenotype.

This study found that neurosteroids can reorganize GABA A receptors in mice, mimicking ovarian cycle changes, with the process being mediated by neurosteroid levels rather than direct hormone receptor activation.

In this study, low-dose spironolactone effectively reduced hirsutism in women and stopped hair loss in one woman with alopecia areata, without significant side effects over 12 menstrual cycles.

5α-Reductase helps regulate hormone action in toad testes, especially during breeding season.

This case report highlights that insulin resistance in PCOS can occur even in underweight patients, as demonstrated by a 24-year-old woman who improved her menstrual cycle, acne, and hirsutism with metformin and dexamethasone over 6 months.

This case study highlights the complexity of managing PCOS and its symptoms in transmen, suggesting hormonal fluctuations may lead to symptomatic relief with low dose estradiol.

This case report describes a rare occurrence of giant bilateral adrenal myelolipomas in a 28-year-old female with CAH, emphasizing that large, hormonally active, or painful myelolipomas should be surgically removed.

This case report describes a 22-year-old woman with hirsutism and irregular menstrual bleeding, diagnosed with an ovarian steroid cell tumor (NOS), whose androgen levels normalized after surgery.

This review discusses polycystic ovarian syndrome, highlighting its symptoms, potential causes, and treatment options, but reports no new clinical results.

An 86-year-old man with prostate cancer was diagnosed with a rare, low-grade breast cancer and underwent surgery but declined additional hormone therapy.

This case report describes a 20-month-old female with a rare adrenocortical virilizing tumor, successfully treated with surgery, showing no pathological lesions over a 10-year follow-up.

This study identified a new genotype, V281+I172N/V281L, linked to non-classical 21-hydroxylase deficiency, suggesting it should be considered in genetic panels for the condition.
