This study highlights the need for a comprehensive andrological assessment at diagnosis, including semen and hormonal analysis, to guide fertility preservation strategies, and found that post-orchidectomy semen samples showed improved DNA integrity for assisted reproductive technologies.

This study found that the absence of Sgk3 in mice leads to impaired hair follicle maturation, characterized by reduced cell proliferation, increased apoptosis, and premature regression.

This article reviews the commonality of androgenic alopecia in men over 30 and the use of finasteride, without reporting new research findings.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This study found that supplementing pregnant Hanshan white cashmere goats' diets with selenium yeast led to higher birth weights, improved cashmere quality and yield, and enhanced hair follicle development in their offspring, possibly through increased antioxidant capacity.

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

This study found that men taking 1 mg/day of finasteride had significantly reduced sperm production and morphology but similar hormonal, sexual, and psychological profiles compared to controls, suggesting finasteride affects semen quality without altering other physiological functions.

Finasteride may decrease semen quality but not harm sperm production, and stopping the drug can improve semen quality; hyperprolactinemia can cause infertility but is treatable with medication.

In this study, researchers observed that after mesenchymal cell division in mouse and chicken embryonic skin, elevated migration speed and persistence for 180 minutes contribute to mesenchymal dispersal and preferential recruitment to dermal condensates.

This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.

This study found that a combination of spermidin, rutine, and zeaxantine effectively reduced staurosporin-induced apoptosis in cultured hair follicle dermal papilla cells, potentially preventing the regression phase in the hair follicle cycle.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

This study found that female Holdobaggy goslings have higher melanin content in their dorsal plumage than males, suggesting that initial plumage color can be used for sex identification.

Finasteride daily doesn't affect sperm production or semen in young men.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

In this study, the antibody A3 identified quiescent post-progenitor epithelial and mesenchymal cells in developing rat hair follicles, suggesting it may help track the differentiation of these cells.

This study found that penile and clitoral differentiation in mice is influenced by androgen exposure, with penile features developing postnatally requiring prenatal and ongoing androgen presence.

This article reviews current approaches to diagnosing and managing haematospermia and reports no new clinical outcomes, highlighting its rare association with malignancy in younger populations.

This study found that mouse hair follicle stem cells use symmetric cell division for maintenance and fate determination, and identified Gata6 as a crucial factor for their differentiation.

This review explores the mechanisms of intratesticular control of steroidogenesis and indicates the need for further controlled studies; it presents no new experimental findings.

This case report suggests that clomiphene citrate can effectively restore fertility in some men with a long history of anabolic steroid abuse, though individual responses to treatment vary.

This study found that salivary testosterone levels were significantly lower in oligospermic and azoospermic men compared to normal men, suggesting its potential use in assessing male androgen status.

This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

This study discovered two new species of mites in the hair follicles of squirrel monkeys from South America, potentially causing follicle damage due to secondary infection.

This study observed that adult offspring of sperm donation generally feel positive about their conception method and believe identifying information about donors should be accessible.

This study found that Muse cells retained their pluripotency and ability to differentiate into various cell types even after being cryopreserved multiple times.

The Trichodysplasia spinulosa virus protein can cause abnormal hair growth in mice.

This study found that the interdigital gland of Vembur sheep has larger secretory lobules in males than females, producing various compounds for chemical communication and foot protection.

Only Deomyinae rodents can regenerate complex tissues.

This study successfully established a transgenic sheep fibroblast cell line expressing the spider dragline silk protein gene, laying groundwork for developing transgenic sheep with this capability in hair follicles.
