This case report describes an adult female with congenital adrenal hyperplasia who developed secondary amenorrhea and hair loss due to androgen overproduction from ovarian adrenal rests, detectable only after pelvic venous sampling, and normalizing after unilateral oophorectomy.

This study indicated that prediabetes may make ovaries more susceptible to PCOS-like changes, with mild hyperglycemia potentially having harmful effects on ovarian health.

This review explores the potential of self-amplifying RNA technology for protein replacement therapy in various health disorders but reports no new experimental results, indicating challenges remain for clinical approval.

This case report describes successful treatment of valproate-induced hyperammonemia in a 79-year-old man using lactulose, marking the first such documented use for this condition.

This study found that glycine treatment inhibited melanogenesis in B16F0 melanoma cells and reduced melanin content in C57BL/6J mice by down-regulating tyrosinase protein levels.

This study reported that mice with more diverse gut microbiota showed higher hair levels of certain hormones and 1-AG compared to those with less diverse microbiota, though plasma differences were more complex and varied by stress and sex.

This study observed that putrescine and HR form a negative feedback mechanism affecting hair cycling, indicating a significant connection between HR, polyamines, and hair growth regulation.

This study describes a method to estimate endogenous hormone production by neutralizing an endogenous hormone with an oppositely acting hormone.

In this study, serum omentin-1 levels were higher in females with idiopathic hirsutism compared to those with hirsutism and polycystic ovary syndrome, suggesting it may help distinguish between these conditions.

In this study, biochemical and clinical hyperandrogenism in PCOS were found to be distinct entities with no strong androgen correlation to clinical symptoms like acne or hirsutism.

This study found that male liver cirrhosis patients have higher estradiol levels and lower dehydroepiandrosterone sulfate, leading to hormonal imbalances favoring estradiol, but without changing sex hormone-binding globulin's binding properties.

In this study, researchers identified two potential urinary biomarkers, testosterone–glucuronide and 11α-hydroxyprogesterone, along with four candidate biomarkers, to help understand and diagnose polycystic ovary syndrome.

In this study, a low-methionine diet significantly improved the health and physical traits of cystathionine β-synthase-deficient mice, contrasting with negative effects on mice with partial deficiency.

This study indicates that the normal human prostate is not a major contributor to circulating blood DHT concentrations in androgen-deficient patients receiving testosterone replacement therapy.

This case report highlights an atypical presentation of vitamin B12 deficiency in a 28-year-old man with reversible symptoms including localized hand hyperpigmentation and megaloblastic anemia, resolved after B12 supplementation.

This study highlights two newly discovered metabolic disorders of biotin, showing distinct skin and hair symptoms and severe complications like acidosis and ketosis.

This case study describes a severe instance of iatrogenic Cushing's syndrome induced by gamma-hydroxybutyric acid, exacerbated by combined use of betamethasone and anabolic steroids, in an HIV-positive patient on cobicistat-containing therapy.

In this study, the inclusion of a feedstuff high in energy along with soybean meal enhanced body condition, body mass index, and reproductive performance in sheep fed low-protein forage.

This study found that in patients undergoing allogeneic hematopoietic stem-cell transplantation, older age significantly increases the risk of hemorrhagic cystitis, especially in males, who are also affected by prostatic hyperplasia.

This study found that a protein-sparing modified fast may safely and effectively help maintain weight loss over a short period when supervised by a physician.

This case study describes a rare instance of virilization during pregnancy in a woman with PCOS, with symptoms resolving post-delivery as testosterone levels normalized.

In this study, researchers identified compound heterozygous variants in the MBTPS1 gene associated with ectodermal dysplasia features in a 14-year-old female, broadening the known disorder spectrum linked to these genetic mutations.

This study suggests that idiopathic hirsutism may involve higher local androgen synthesis despite normal serum androgen levels, challenging its categorization as idiopathic.

Women with severe acne, hirsutism, and androgenic alopecia often have higher levels of certain androgens, but the specific pattern can't be predicted just by looking at symptoms.

In this case report, a young man with primary hypothyroidism caused by autoimmune atrophic thyroiditis showed full recovery and normalization of metabolism after levothyroxine treatment.

This study suggests that arginine and cysteine deficiency is not present in women with chronic telogen effluvium, indicating that amino acid supplementation may be unnecessary in nutrient-replete populations.

This study found that female patients with telogen effluvium had significantly lower serum prolactin levels compared to healthy controls, which contrasts with previous findings linking higher prolactin to hair loss.

This study observed that many women with PCOS had unfavorable lipoprotein profiles, mostly moderate changes in triglycerides, HDL, and LDL cholesterol, with small LDL particles not being rare and potentially aiding risk assessment.
