The researchers reviewed the status, challenges, and future prospects of CRISPR/Cas9-mediated gene-editing technology in livestock breeding, noting its benefits and highlighting concerns about low efficiency in inserting foreign genes and off-target effects.

This review discusses the impact of HRT on menopausal skin and hair symptoms and argues that potential benefits should be part of informed decision-making for managing menopause.

This study found that cetaceans have adapted their fibroblast growth factors to assist in low bone density, hypoxia tolerance, and the development of rigid flippers, reflecting significant evolutionary changes for aquatic life.

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 found that finasteride treatment of male rats led to changes in their male offspring's testicular gene expression, potentially affecting sperm function in response to odorant-like signals.

This study found that COVID-19 infection disrupts spermatogenesis, alters testicular cell populations, and may impact male fertility by causing long-term changes in testicular function and reduced sperm quality, as observed even in patients who have recovered from the acute phase of the infection.

In this animal study, finasteride exposure led to impaired spermatogenesis in rats, while the novel compound DA-9401, derived from three medicinal herbs, demonstrated potential in improving sperm parameters and reducing testicular apoptosis when used alone or with finasteride.

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

This review examines the negative effects of anabolic-androgenic steroid use on the male reproductive system, including impaired testosterone production, sperm production issues, and adverse metabolic consequences without reporting new clinical results.

In this narrative review, researchers reported that oral finasteride significantly improved hair count and density in male androgenetic alopecia but had higher systemic exposure and potential side effects compared to topical formulations, which provided similar efficacy with lower systemic DHT suppression.

This review discusses the therapeutic properties of polydeoxyribonucleotides derived from marine organisms for wound healing and inflammation, but it reports no new clinical results.

This study observed that numerical chromosomal aberrations were more common in men with severe male factor infertility and azoospermia compared to those with other sperm quality issues, while chromosomal translocations were significantly associated with oligoasthenozoospermia, highlighting important genetic counseling considerations.

In this study, maternal melatonin implantation in pregnant rabbits reduced hair follicle cell apoptosis and increased hair follicle density in their neonatal offspring, suggesting a beneficial impact on hair follicle development mediated through specific molecular pathways.

Hormonal contraceptives are effective for teens but require careful consideration of side effects and individual health.

This article reviews the clinical and diagnostic features of hair shaft disorders, emphasizing the role of structured patient assessments and the avoidance of hair trauma, but reports no new results.

This article reviews current osteoporosis treatments, focusing on the potential of selective androgen receptor modulators and other agents to enhance bone formation, but provides no new clinical data.

This article reviews the use of finasteride for treating male pattern hair loss, highlighting its mechanism of action in reducing DHT and noting its safety profile with some common adverse effects.

This review outlines the steps of contemporary hair transplantation surgery, including the roles of medications and nonsurgical options, but it reports no new clinical findings.

This article reviews the roles of lesser-known secreted phospholipase A2 isoforms in various biological processes, such as immune suppression, metabolic regulation, epidermal hyperplasia, and male reproduction, without reporting new clinical findings.

This review discusses current and emerging medical therapies for androgenetic alopecia but reports no new clinical findings, emphasizing the importance of stabilizing the condition as a complement to surgical hair restoration.

This study found that a regimen combining cyproterone acetate and testosterone buciclate induced reversible azoospermia in bonnet monkeys, highlighting its potential as an effective male contraceptive.

This review discusses the potential health benefits of Allium vegetables, especially their association with reduced cancer risk, but reports no new clinical outcomes.

This study observed that herbal feed supplementation in Frieswal breeding bulls improved semen volume and motility, while significantly lowering dihydrotestosterone levels, suggesting a potential mechanism for enhancing semen quality.

This study suggests that the testosterone analogs 7α-Methyltestosterone and 7α-Ethyltestosterone may offer promising androgenic, progestogenic, and anabolic properties for development as male contraceptives.

This study found that obesity in women may impair endometrial stromal function and contribute to reproductive complications, possibly due to metabolic influences rather than immune cell differences.

Certain micronutrients may improve hair and nail health, but more research is needed to confirm their benefits.

Dutasteride is more effective than finasteride for hair growth, and sublingual apomorphine quickly improves Parkinson's symptoms.

This review discusses the potential of polydeoxyribonucleotide (PDRN) for various dermatological treatments and highlights its significant effects on wound healing, anti-aging, acne scars, and hair loss, but emphasizes the need for further clinical studies.

This review highlights potential negative impacts of certain medications on male fertility, such as hormonal disruption and germ cell toxicity, emphasizing the importance of clinicians being aware of these effects to advise on safer alternatives.

This review discusses androgen therapy in adolescents, detailing current practices and noting the limited use of commercially available testosterone or dihydrotestosterone formulations; no new results are reported.
