This study found that young adult men with moderate to severe AGA have poorer semen quality compared to those with normal to mild AGA.

In this case report, treatment with antibiotics, finasteride, and prostate omentalization restored fertility in a 6-year-old German Shepherd with prostatitis and astenoteratozoospermia, avoiding surgical castration.

This study confirmed that a rare dermatophyte infection in a young cat was caused by Arthroderma gypseum, identified using molecular analyses.

This study identified a subtype of itch-sensing neurons in mice, which express Ret and somatostatin, and found that their ablation reduces scratching induced by certain pruritogens.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

This review discusses hormonal changes in aging men and suggests the need for more research on androgen supplementation and partial androgen deficiency, without presenting new clinical findings.

This study suggests that spiny keratoderma may be an ectopic hair formation on palms and soles, based on keratinization patterns observed using antikeratin antibodies and electron microscopy.

This study found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

This research on dermal papilla cells found that Sparasis crispa increased mRNA expression related to hair production and may help in hair generation cycles, but its impact on male hair loss treatment remains uncertain.

This study reported that mSKPs and DMSCs share similarities in biological characteristics but exhibit distinct transcriptome profiles, with mSKPs being more immune-related and DMSCs more associated with differentiation and disease pathways.

The study demonstrated that bulge stem cells from rat vibrissa follicles respond to adult dermal papilla signals, inducing hair bulb formation and regenerating hair structures in vivo.

This study established a stable rabbit model of hypospadias using finasteride, finding varied rates of the condition's severity and associated testicular retention across different gestation day treatments.

This review examines the skin manifestations of various endocrine disorders, highlighting their underlying pathophysiology and impact on an individual's health and quality of life, without reporting new research findings.

This study found that blocking androgen receptors inhibits testicular descent in rats more effectively during the early stages of gubernacular outgrowth than inhibiting 5a-reductase.

Slug (Snai2) helps regulate hair growth timing in mice.

This study reports that side-population stem cells, distinct from hair follicle stem cells, may play a significant role in the malignant progression of squamous cell carcinomas in mice.

This study described the structure of the hair brush on male Endoclita vietnamensis moths' legs, identifying characteristics such as specialized scales and a pheromone gland, which could facilitate the future development of pheromone-based pest control methods for eucalyptus pests in China.

This study identified specific genes and pathways in human Leydig cells that may contribute to Post-finasteride Syndrome, potentially informing future treatments to reverse persistent side effects.

This study found that Hex gene expression patterns in chick embryo dorsal skin during feather bud development suggest a significant role in initiating feather morphogenesis.

This study found that twice-daily intradermal injections of mouse epidermal growth factor in Merino sheep resulted in dose-dependent changes in wool follicles and fibres, including induction of catagen and subsequent regeneration.

This study found that in male rats, hesperidin co-administration ameliorated finasteride-induced testicular toxicity by reducing oxidative stress and improving antioxidant status, sperm parameters, and enzyme activity compared to finasteride treatment alone.

In this study, mouse amnion epithelium was successfully transformed into skin and hair follicles when associated with hair-forming dermis, revealing the necessity of specific influences for follicle formation.

This study revealed that deleting EZH2 in mesenchyme-derived cells of the female reproductive tract led to impaired uterine gland development and pregnancy loss in mice, highlighting EZH2's crucial role in fertility.

This study found that human sweat glands contain unique stem cells with significant multilineage differentiation potential and self-renewal abilities, suggesting promising clinical applications due to easy biopsy access.

This study identified a new gene, mrp4, in mice, which suggests it may have a unique role in the growth and development of hair follicles in the ears and tails.

This study found that mouse embryoid bodies adhered quickly and differentiated efficiently into cardiomyocytes on negatively charged poly(sodium p-styrene sulfonate) hydrogels, similar to their behavior on gelatin-coated polystyrene.

In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.

In this study using Xenopus laevis embryos, reduced levels of the desmosomal protein desmoplakin led to defects in epidermal and cardiac structures, suggesting its crucial role in tissue integrity.

Mice hair follicles take in the amino acid cystine.
