This study observed that hairless rat skin was more permeable to mannitol and progesterone than hairy rat skin, indicating that follicular structures significantly impact percutaneous absorption.

This study found that finasteride increased fetal arousal activity in late gestation sheep by suppressing pregnane steroid synthesis, suggesting reduced GABAA receptor-mediated inhibition.

This review discusses the sex differences in neuroactive steroid synthesis and their implications for nervous system functions and potential therapeutic approaches, but it provides no new experimental results.

This article reviews the clinical presentations, pathophysiology, and treatment options for various skin conditions in children with skin of color and reports no new findings.

This study found that in androgenic alopecia, the arrector pili muscle degenerates and is replaced by fat, unlike in normal skin or telogen effluvium.

This study found that polymers significantly improved the chemical and microbial stability of steroid hormones in liposome formulations over eight weeks, with finasteride showing the highest diffusion rate.

This study observed that the binding of certain hormones in rat skin varies cyclically with the hair cycle phases, with testosterone showing maximum binding in the catagen phase.

In this study, several compounds, including estrogen and Dutasteride, showed neuroprotective effects on dopaminergic neurons in an MPTP mouse model of Parkinson's disease.

This report describes a case of meningioma in a transwoman treated long-term with estradiol and cyproterone acetate, suggesting possible concern over female sex steroids and meningioma risk.

This study suggests that higher PDCD4 expression may play a significant role in polycystic ovary syndrome pathogenesis through its association with obesity, insulin resistance, lipid metabolism disorders, and increased granulosa cell apoptosis.

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 that hair follicle stem cells from hidradenitis suppurativa patients showed alterations in cell cycle regulation and DNA replication, potentially linking genetic predisposition to the skin inflammation characteristic of the disease.

This study describes molecular mechanisms explaining how sex and stress steroids rapidly modulate dendritic spine formation in hippocampal neurons, suggesting recovery-like effects under steroid-depleted conditions compared to intact conditions.

This study found that measuring reproductive hormone levels in brown bear hair may effectively support non-invasive genetic sampling, though larger samples or more sensitive techniques are needed for broader application.

This article reviews diagnostic criteria and treatment options for polycystic ovary syndrome, focusing on hormonal and metabolic management strategies, and presents no new clinical data.

This review summarizes the anatomy and physiology of the arrector pili muscle and discusses its potential role in hair loss disorders, reporting no new clinical results.

This article reviews current treatment options for acne, hirsutism, and androgenetic alopecia in women with PCOS, recommending individualized and multidisciplinary approaches, but reports no new clinical results.

This study found that the Gsdma3 gene is necessary for normal hair follicle differentiation in mice, with its mutation leading to progressive hair loss and defects in hair structure.

This review discusses the mechanisms by which isotretinoin and hormonal therapy treat acne through their effects on sebaceous glands, reporting no new clinical results.

This paper discusses hormonal therapy options for women with severe acne, focusing on treatment for cases that do not respond to conventional methods, but it reports no new clinical findings.

This review explores how cell and mouse models have contributed to understanding the mechanisms of human aging, particularly focusing on Hutchinson-Gilford Progeria Syndrome, and reports no new clinical results.

This review discusses factors affecting fertility in both men and women with congenital adrenal hyperplasia and emphasizes individualized preconception management but reports no new clinical results.

This article explores questions about dormant hematopoietic stem cells and suggests avenues for future research, but does not present new experimental results.

This study found that topical trypsin application after hair removal in mice led to cell death at the follicular papilla, which delayed hair growth and pigmentation.

This article reviews studies on thyroid influence on hair growth, noting varied results, including accelerated growth in some normal and underfed rats after thyroid administration, but reports no clinical results.

This study found that acute sleep deprivation enhanced 5α-reductase expression and activity in the rat prefrontal cortex, and finasteride treatment reduced associated psychosis- and mania-like behaviors.

In this study, topical minoxidil did not show an antiandrogenic effect on androgen-dependent cutaneous structures in the golden Syrian hamster, suggesting it likely does not have this role in humans either.

This study suggests that stress may worsen Tourette syndrome symptoms in mice by increasing allopregnanolone synthesis, with findings supporting finasteride as a potential treatment to manage symptom fluctuations.

This study found that the progesterone metabolite 3α-THP increased the proliferation and gene expression of human glioblastoma cells, suggesting a role in tumor progression.

This study found that hair products commonly used by Black women exhibited hormonal activity, which could impact health outcomes and contribute to health disparities.
