This study found that chronic administration of dutasteride in rats did not affect spermatogenesis or oxidative stress in the testes, although it altered hormone levels.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

Understanding genes and hormones is crucial for managing male puberty and sex development disorders.

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.

This case report describes two infertile patients who experienced significant improvements in sperm concentrations six months after stopping finasteride.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.

This study reports the first instance of skin autotomy in mammals, specifically in African spiny mice, and suggests they may possess a greater regenerative capacity than previously understood, possibly offering insights for regenerative medicine.

This study observed that male-to-female skin grafts were consistently rejected in mice due to sex-linked histocompatibility antigens, suggesting potential applications for distinguishing between X- and Y-chromosome-carrying sperm.

This case report described a 39-year-old male with 47XXY/46XX mosaic Klinefelter syndrome who presented with common features of the condition and male pattern baldness seen in his family.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This study suggests that in gilthead seabream, DHT is involved in the onset of the meiotic phase of spermatogenesis and influences serum levels of E2 through regulation of aromatase activity.

Environmental factors and exposure to toxins may contribute to male infertility by affecting sperm and hormone function.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

This review suggests that telocytes in male reproductive organs help organize tissue structure and paracrine factors, impacting organ development and pathology, but more research is needed on their molecular pathways.

This study found that slow vitrification using DMSO for cryopreserving hair follicle germs in mouse skin showed effective hair regeneration, making it a promising method for hair regenerative medicine.

This study found that hair-follicle-associated-pluripotent (HAP) stem cells can be cryopreserved for future use in nerve and spinal cord repair, with human trials being planned.

This study investigated NNAT expression in embryonic and postnatal rat tissues, finding its localization in both undifferentiated and differentiated cells across tissues such as the pancreas, tongue, and testis.

This study found that centrosomes, unlike cilia, are essential for proper epidermal and hair follicle development in mice, with these effects being dependent on the presence of p53.

This report describes a rare case of scalp kerion due to microsporosis in a Portuguese child, noting the unusual combination with other microsporid features and treatment details.

In this study, Akt2 and the oncogenic protein Tcl1 were found to be essential for early blastomere proliferation and embryo development in preimplantation mouse embryos.

Finasteride negatively affects fish reproduction and gonadal development.

This study found that administering lycopene to rats provided significant protection against the testicular damage caused by finasteride, as indicated by improved sperm parameters, and reduced oxidative stress and apoptosis markers.

In this study, Sox13 was identified as a novel marker for early hair follicle development and differentiation in mice, though it appears to be dispensable for overall epidermal and adnexal development.

This study observed that the catagen phase in hairless mice displayed a slower shortening of the mutant epithelial column, resulting in longer total follicle length and abnormalities in the connective tissue sheath and glassy membrane.

This study found that sphynx cats exhibit hair follicle dysplasia with abnormal hair shaft production, but without a reduction in the number of follicles, similar to murine KRT 71 mutants.

In this study, a computational analysis of promoter regions in human fertility-related genes identified several new candidate regulatory motifs, but these require further experimental validation due to the limitations of being an in silico examination.

This study found that injecting thymus gland extracts into albino rats significantly accelerated growth and morphological differentiation across generations, including earlier sexual maturation and development of features like hair and teeth.

This meeting abstract details various lectures and workshops from the 30th Annual Meeting of the American Society of Andrology, including findings on genetic and physiological factors affecting male fertility, but reports no new clinical results.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

This study reports that patients with Alzheimer's disease have increased levels of polyamines in their hair.
