This article discusses laboratory and physical markers that may help detect androgenic anabolic steroid abuse in athletes and reports no new primary research results.

This review discusses the degenerative effects of anabolic-androgenic steroids on the nervous system and reports no new experimental results, aiming to increase public awareness of their health risks.

This review discusses the physicochemical properties, binding mechanisms, and factors affecting corticosteroid-binding globulin (CBG) functions, but reports no new clinical results.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

This study found that resveratrol significantly alleviated testicular damage in male rats caused by finasteride, which otherwise led to decreased testosterone levels and various histopathological alterations in the testes.

This report highlights the usefulness of specific diagnostic procedures, including penile/preputial cytology and transabdominal ultrasonography, in diagnosing cryptorchidism and Sertoli cell tumors in dogs with generalized skin conditions.

This study used proteomics to identify various proteins in human hair, which may help develop novel biomarkers for hair health, disease, and aging.

This study found that Cyanidin-3-O-glucoside and Vitisin A were able to penetrate mouse skin and improve issues related to hair follicle miniaturization and apoptosis in androgenetic alopecia, suggesting these compounds as potential alternative treatments for hair loss.

This study demonstrated that the highly divergent WDSV rv-cyclin significantly stimulates eukaryotic cell proliferation, leading to hyperplastic skin lesions in transgenic mice.

This study concluded that the process of mummification disfigures facial features, making identification challenging, but commercial shrunken heads retain more defining features compared to ceremonial ones.

This article reviews the skin condition myxedema associated with hypothyroidism, highlighting its characteristic non-pitting, glycosaminoglycan-rich nature, and reports no new results.

This case report describes a 45-year-old woman with diffuse nonscarring alopecia characterized by hair thinning, increased catagen/telogen follicles, and mild inflammatory infiltrate, highlighting the diagnostic findings via scalp dermoscopy and biopsy.

Fibrosing alopecia in a pattern distribution is a unique hair loss condition with inflammation and scarring, resembling but distinct from common balding.

In this study, transgenic mice expressing Msx-2 developed flaky skin with hyperproliferation and misalignment in epidermal cells, suggesting Msx-2 plays a role in skin and appendage growth control.

In this study, finasteride treatment for 56 days in adult rats led to sloughing of immature germinal cells and reduced sperm content in the epididymis, indicating its importance for maintaining spermatogenesis.

This study found that finasteride treatment in adult hamsters led to significant testicular alterations and reduced spermatogenesis compared to untreated controls.

This study found that testosterone, finasteride, and castration in rats decreased serum thyroxin levels, with testosterone also affecting body and prostate weights.

This review discusses scrotal rejuvenation procedures and treatments, highlighting a growing interest in this area due to increased awareness of potential scrotal conditions and available interventions.

This animal study found that testosterone treatment increased vas deferens fluid secretion rate in rats, with potential implications for male fertility through the upregulation of AQP-1, 2, and 9 proteins.

In this study, finasteride treatment for male pattern baldness improved hair loss and reduced prostate size, while increasing testosterone levels and altering steroid hormone ratios without affecting gonadotropin levels.

This study found that in male rats, finasteride significantly decreased spermatogonia and primary spermatocytes numbers and increased Leydig cells, but did not affect overall testis histology or spermatogenesis.

In this laboratory study with rats, treatment with finasteride reduced dihydrotestosterone levels and fertility parameters, with a 30-day recovery period proving insufficient to fully restore sperm function and fertility.

This study reports a rare case of polyorchidism in a 96-year-old male cadaver, suggesting a new classification based on anatomical and histological findings to aid in accurate diagnosis.

This study found that Epristeride and Finasteride reduced prostate development and testis weight in male rats, but only Finasteride appeared to impact reproductive function.

This study found that oral administration of finasteride to pregnant rats caused dosage-related developmental toxicities, including hypospadias and decreased anogenital distance in male offspring.

This study found that finasteride-induced DHT deficiency altered estrogen receptor expression in the epididymis, potentially destabilizing its function.

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.

In this study, administering 5alpha-reductase inhibitors reduced dihydrotestosterone levels and was associated with mild, reversible decreases in semen parameters in healthy men.

In this case study, a male miniature dachshund with alopecia was diagnosed with estrogen-secreting Sertoli cell tumors and seminoma, with the alopecia resolving post-surgical removal of the tumor.

This study found that Sonic Hedgehog protein treatment enhanced the sprouting and regeneration of pelvic ganglia and cavernous nerves after injury, with localization of delivery affecting outcomes.
