This review discusses the side effects of gender-affirming hormone therapy and reports no clinical results; it highlights the potential to reduce adverse effect risk factors with healthy eating guidelines.

This article reviews the use of hair cortisol concentration as a biomarker to assess long-term stress in both animals and humans, but it reports no new experimental results.

This study found that steroid hormones influence the quality indicators of fresh and cryopreserved stallion sperm, with testosterone negatively correlated with motility and estradiol positively correlated with survival rate.

In this case series, two cats with hypothyroidism and hyperthyroidism achieved clinical remission and normal thyroid function following timely diagnosis and targeted treatment with levothyroxine and methimazole, respectively.

This study demonstrated that cortisol, estradiol, and testosterone are preserved in archaeological human hair, allowing for the analysis of ancient stress and reproductive hormone patterns.

This study found no significant difference in semen parameters or reproductive hormone levels between men taking low-dose finasteride for androgenic alopecia and those not on the medication.

This study found that the peach gene CTG134, involved in auxin-ethylene interactions, plays a role in hormonal regulation during root hair formation in Arabidopsis and tobacco.

This review discusses the role of corticotropin-releasing hormone in human skin, focusing on its regulation, receptors, and functions, and highlights parallels with the hypothalamo-pituitary-adrenal axis; it reports no new research findings.

This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

In this study, researchers found that caffeine can counteract stress-induced damage in ex vivo human androgenetic alopecia hair follicles, suggesting it may help prevent stress-related hair loss.

This review discusses recent advances in the understanding of alopecia areata, focusing on immunity and genetics, and presents potential targets for therapy without reporting new clinical results.

This study found that patients with alopecia areata exhibited increased CRHR1 expression on circulating monocytes compared to controls, suggesting that stress-related factors like CRH and CRHR1 may contribute to the development and progression of the condition, particularly in chronic cases and those with larger lesions.

This review discusses the biological and cosmetic aspects of hair aging and reports no new clinical results; it highlights current treatments and future research directions to address both aging factors.

This study found that individuals with a recent history of suicide attempts exhibited altered DHEA hair levels, suggesting possible dysregulation of the HPA axis as a biopsychosocial feature, and recommends further investigation into hair hormones as potential markers of suicidal crisis and vulnerability.

This study observed that pediatric patients with diffuse, non-scarring alopecia had significantly lower levels of zinc and folate compared to matched healthy controls, suggesting a possible link between these deficiencies and hair loss in children.

This study involving 81 yaks found significant correlations between melatonin, dihydrotestosterone, and immunoglobulin levels in blood serum and mineral content in hair, suggesting these factors may jointly influence yak hair growth and immune status, providing a potential non-invasive indicator of overall health.

This study found that low ferritin levels are associated with higher telogen ratios in women with diffuse hair loss, suggesting an important role of ferritin in telogen effluvium diagnosis.

This article reviews the role of factor Xa inhibitors like Rivaroxaban and suggests they may eventually replace vitamin K antagonists, but their side effects require further clarification.

This paper reviews the diagnostic criteria, etiological factors, and treatment approaches for PCOS, highlighting the importance of considering metabolic issues such as insulin resistance and obesity, but reports no new findings.

This study found that a thyroid hormone receptor ẞ subtype-selective thyromimetic was effective in promoting hair growth in mouse and monkey models when applied topically.

This chapter reviews various antiandrogens and androgen inhibitors, detailing their mechanisms, uses, and side effects, with a focus on spironolactone, finasteride, dutasteride, and oral contraceptives.

This paper discusses the link between polycystic ovarian syndrome (PCOS) and health issues like infertility and cardiovascular diseases, caused by both genetic and environmental factors, but reports no new clinical findings.

This study found that dihydrotestosterone treatment in female rats altered anterior pituitary gland gene expression, with significant repression of prolactin and inhibition of GnRH receptor gene expression, suggesting specific hormone production changes.

This article reviews current guidelines for diagnosing, treating, and providing holistic care for women with polycystic ovary syndrome, without presenting new clinical findings.

This review discusses the management of polycystic ovary syndrome in women and reports no new clinical results.

In this report, a 47-year-old woman with subclinical hypothyroidism experienced significant symptom relief and normalized TSH levels after six months of individualized homeopathic treatment with Sepia 1M, targeted to her symptom profile.

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.

This case report details a 37-year-old woman with alopecia areata who experienced significant hair regrowth after psychological stress-triggered hair loss, following treatment with topical corticosteroids and tofacitinib.

In this study, 35.4% of telogen effluvium patients showed ferritin deficiency and 34.2% had vitamin D deficiency, suggesting these should be included in TE screening; TSH testing should be individualized.
