This study found that disrupting Smad4 signaling in young mice led to overactivation of follicle stem cells, causing hyperplasia and depletion of the stem cell niche.

In this study, researchers used a hypospadiac rat model to demonstrate abnormal genital development, similar to human penoscrotal hypospadias, highlighting the model's value for studying penile growth and differentiation.

This study highlighted that Sertoli-Leydig cell tumors should be considered in young women with secondary amenorrhea and virilization, and fertility-preserving surgery can be effective when diagnosed early.

This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This review discusses the antimicrobial and protective effects of hesperidin and hesperetin against various toxicities, with potential mechanisms explored, but it reports no new research findings.

Male infertility and genitourinary birth defects are often linked to genetic issues.

This study found that the Arabidopsis thaliana protein Formin 2 localizes to plasmodesmata and is crucial for regulating their permeability by anchoring actin filaments, which affects virus susceptibility.

This abstract discusses the effects of finasteride on semen and hormone parameters in men with infertility but does not provide new research findings.

This systematic review found that mixed epithelial and stromal tumor of the seminal vesicle (MESTSV) is characterized by abundant stromal proliferation, architectural heterogeneity, and strong immunoreactivity for ER/PR, with most being benign but warranting surveillance for possible recurrence or metastasis.

This study found that 5-aminolevulinic acid significantly improved chicken sperm motility and increased mitochondrial membrane depolarization, while decreasing ATP levels.

This study demonstrated a method for large-scale preparation of self-sorted hair follicle germs in vitro, which successfully generated hair follicles when transplanted into the skin of nude mice.

This review highlights the limited effectiveness of current unlicensed treatments for male subfertility, like hormonal therapy and antioxidants, and emphasizes new drug discovery methods such as high-throughput screening and drug repurposing to improve treatment development for male subfertility.

This study found that mouse vibrissa follicles in early anagen grew better than in other hair cycle phases, and growth was enhanced by removing the upper follicle third in vitro.

In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.

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 hesperidin, a bioflavonoid, mitigated the negative effects of finasteride on sperm health and testicular structure in male Wistar rats by reducing oxidative stress and apoptosis and supporting testicular antioxidant capacity.

In this study, Nephrolepis biserrata extract significantly improved fertility indices in male Wistar rats with testosterone propionate-induced benign prostatic hyperplasia, showing increased sperm count and reduced prostate weight, suggesting potential pro-fertility benefits for BPH-related infertility.

This case report describes a young female with a rare combination of 46,XX gonadal dysgenesis and MRKH syndrome, highlighting associated infertility challenges.

In this study, researchers reported telocytes in the dermis of silky fowl embryos at different developmental stages, highlighting their immunophenotypes and interactions with other cells.

This case report describes a rare instance of dermatophytosis in a young cat caused by Microsporum gypseum, confirmed by molecular analyses to be Arthroderma gypseum.

This study suggests that the down-regulation of 14-3-3 proteins in wild-type keratinocytes, absent in Smad4 mutant keratinocytes, might contribute to the failure of hair follicles to initiate catagen in Smad4 knockout mice.

In this study, melatonin administration enhanced various cellular and structural features of the scrotal skin in Soay rams, including increased thickness, cell count, and gland activity.

In this study, nestin-expressing cells in the hair follicle bulge, marked by GFP in transgenic mice, were identified as progenitors of the hair follicle outer-root sheath.

This study found that progesterone increased the survival of newborn neurons and enhanced spatial learning and memory in adult male mice, independent of neuron production changes.

This study reported that seminal vesiculoscopy combined with transurethral resection of ejaculatory ducts and balloon dilation effectively resolved hematospermia and improved symptoms in a patient whose condition was unresponsive to medical treatments.

This study found that finasteride induced infertility and increased endoplasmic reticulum stress in rats, but these effects were mitigated by DA-9401 administration.

This study found that dermal fibroblast cultures, especially those with higher alpha-smooth muscle actin expression, can be used to produce skin-derived precursor cells, unlike human hair follicle dermal papilla cultures.

This study indicates that the Sp6 gene is crucial for the development of skin, teeth, limbs, and lungs in mice, possibly through regulating apoptosis.

This article reviews the effect of aging on male hormone levels and fertility, highlighting the need for more research on the benefits and risks of androgen supplementation in older men.
