This review discusses the pathways of androgen biosynthesis and reports no new findings, highlighting the need to understand the interplay between the classic and backdoor pathways.

This study found that autophagy in the preputial glands of mice plays a crucial role in regulating lipid and fatty acid metabolism, as well as pheromone production.

This study observed that Yuyi hairless mice develop alopecia shortly after birth, with the skin eventually thickening and forming folds, and hair failing to regrow as they age.

This case study reported that after removal of an interstitial cell tumor from a ruffed lemur, the animal experienced improved coat quality and a return to normal behavior without signs of cancer spread.

In this study, researchers investigating the Drosophila testis niche system reported that Notch signaling is crucial for niche cell specification, with early gonadogenesis showing signals coming from outside the gonad to direct cell fate.

This study found that administering dutasteride did not change spermatogenesis or oxidative stress levels in rat testes, though further research is needed to confirm these findings.

In this study, differences in protein expression related to twin lambing were identified in Tibetan sheep, providing insights into the reproductive performance and fertility improvement strategy for sheep in the Qinghai-Tibet Plateau.

This study is the first to document significant age-related pathologies in endangered captive Julia Creek dunnarts, highlighting hormonal dysregulation and reproductive issues in females, while males exhibited higher occurrences of cutaneous diseases and testicular degeneration, providing valuable insight for conservation efforts.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

This review discusses recent research on male infertility causes and treatments, emphasizing the need for further understanding of idiopathic sperm abnormalities and molecular factors to improve patient outcomes; it reports no new clinical results.

This study describes a novel method using force-triggered density gradient sedimentation for efficiently isolating dermal papilla cells from neonatal mouse skin, showing promise for hair follicle regeneration research.

This study observed that low-dose intrauterine exposure to finasteride alters postnatal prostate development in male and female Mongolian gerbils, showing sex-specific differences in receptor expression and tissue changes.

This study found that gamma-ray exposure on the day of fertilization or the day after increased genome editing efficiency in pregnant mice using the i-GONAD method, potentially aiding in the creation of diverse experimental animal models.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study demonstrated that ND-GFP stem cells from the hair-follicle bulge area can differentiate into various cell types, including neurons, suggesting their potential as a source for therapeutic applications.

This study found that tyramine-linked hyaluronan gel effectively supports the 3-D culture of ovarian follicles, facilitating the maturation of functional metaphase II oocytes that can develop into blastocysts.

The researchers reported that in Arabidopsis collet hairs, nuclear positioning near the cell tip is not essential for hair growth, although it correlates with growth dynamics.

This study found that keratinocytes derived from the germinative epithelium of ovine hair follicles have extensive in vitro growth potential, challenging the idea that these cells are solely transit-amplifying.

This study reports for the first time on the expression patterns of Id2 and Id3 proteins in developing hair follicles, suggesting a significant role for these proteins in hair follicle development and epithelial-mesenchymal interactions.

This study found that teenage girls born via assisted reproductive technologies displayed premature development of secondary sexual characteristics and elevated hormone levels, indicating late precocious puberty and androgen excess.

In this study, fetal stem cells were identified in adult human hair follicles long after childbirth, indicating potential for autologous therapies due to their pluripotent characteristics.

This study demonstrated that hyaluronan gel is a promising biomaterial for 3-D in vitro culture of mouse ovarian follicles, supporting the production of fertilizable metaphase II oocytes.

This abstract provides a graphic illustrating that mice lacking the Sgk3 gene exhibit thin coats and abnormal hair, suggesting a role for Sgk3 kinase in hair follicle growth, but reports no new experimental findings.

In this study, transplanted whisker follicles from ND-GFP mice aided spinal cord repair in injured mice, and surprisingly, also grew long hair shafts at the site of transplantation.

This study observed that intrauterine and early postnatal exposure to finasteride affected prostatic development in Mongolian gerbils, with significant sex-based differences, particularly higher alterations in female prostates.

This study reports that simultaneous cystoscopy, electroejaculation, transurethral resection of ejaculatory ducts, and seminal vesiculography were safe and effective in diagnosing and treating concurrent hematospermia and anorgasmia.

This study found that inhibiting the 5alpha-reductase 2 pathway in male rats affects brain sexual differentiation and leads to reproductive changes, including increased pre-implantation loss despite unchanged copulatory potential.
