In this study, male patients treated with 150 mCi of radioactive iodine showed no negative impact on fertility, but long-term studies with larger groups are needed to further assess hormonal effects and sperm health after this treatment.

This study found that activation of Wnt/β-catenin signaling in mouse testes promotes spermatogonial differentiation and reduces the stem cell pool, with SHISA6 inhibiting this process and maintaining stem cell characteristics.

In this study, testosterone and finasteride were found to increase insulin and zinc levels while decreasing chromium levels in male adult rats, suggesting potential effects on the glucose cycle.

This article examines the evidence regarding finasteride's sexual side effects and offers recommendations for patient counseling but reports no new clinical findings.

This study found that discontinuing finasteride led to a significant increase in sperm counts for most men with reduced fertility, though hormone levels and other semen parameters remained unchanged.

This review summarizes how common polymorphisms in androgen and estrogen receptor genes may influence aging-related symptoms and diseases in men, but it reports no new clinical results.

In this study, flutamide at therapeutic doses caused significant histological changes in the testes and epididymis of adult albino rats, reducing androgen receptor immunoreactivity and increasing estrogen receptor immunoreactivity.

This discussion highlights the use of minimal incision extraction for lipoma removal, noting that it is a favored technique among dermatologists due to its efficiency, despite some hesitance with larger lipomas.

In this study, high doses of Lepidium sativum seeds extract were reported to cause toxicity and tissue damage in animals, suggesting the need for careful use under medical supervision.

This study reported that certain newly synthesized steroidal derivatives showed stronger inhibitory activity against the 5α-reductase enzyme than finasteride in hamsters, suggesting their potential as enzyme inhibitors.

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

In this study, topical application of a 10% minoxidil lotion on mature rats over 72 days was associated with reduced testis and epididymis mass and sperm motility, indicating potential gonadotoxic effects.

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 investigated nanocomposite scaffolds made from alginate, chitosan, and graphene oxide to promote the proliferation of spermatogonial stem cells, finding the ALGCS/GO30 scaffold to be particularly effective due to increased proliferation markers and PLZF protein expression compared to controls.

This study reported significant improvements in sperm concentration in two cases of azoospermia and severe oligospermia after discontinuing finasteride 1 mg used for hair loss.

This review discusses the potential persistent adverse effects associated with 5α reductase inhibitor treatment for androgenetic alopecia but provides no new clinical results; it emphasizes the importance of discussing these risks with patients.

This review highlights that various commonly prescribed medications for chronic conditions may impact male fertility by affecting hormone secretion, sperm production, ejaculation, erectile function, and libido, although conclusive evidence is limited to specific drug groups.

This study found that while finasteride effectively improves hair growth in male androgenetic alopecia, it may affect fertility at higher doses, and the evidence on its long-term sexual side effects is inconsistent and requires more rigorous research.

In this study, oral melatonin given to male Pomeranian dogs with Alopecia X improved semen quality and testicular blood flow in a dose-dependent manner, but altered hormonal balance, indicating complex effects that require further investigation for long-term implications.

This special issue contains abstracts from the ASA 40th Annual Meeting, providing an overview of various studies without reporting new primary results.

In this study on Danio rerio, researchers found that exposure to titanium dioxide nanoparticles did not affect embryonic development but altered the structure of male gonads, acting as potential endocrine disruptors with androgenic activity.

This review discusses the degenerative effects of anabolic-androgenic steroids on the nervous system and reports no new experimental results, aiming to increase public awareness of their health risks.

This commentary reviews the post-Finasteride syndrome and argues that while the condition's validity is debated, comprehensive guidelines are needed to address related risks and treatment options; it reports no new clinical results.

This review discusses the dual role of testosterone in COVID-19 progression and suggests its importance in understanding the disease's mechanisms, highlighting the need for further targeted research.

Among adult male rats, this study found that combined exposure to lithium carbonate and lead acetate over 28 days led to synergistic cardiotoxic effects, evidenced by oxidative stress, ECG abnormalities, and molecular markers of increased apoptosis, despite no observable structural damage to myocardial tissue.

This review examines the therapeutic effects of photobiomodulation on severe medical illnesses but reports no new clinical results; it emphasizes its potential in neurology, pulmonology, inflammation, dermatology, wound healing, and oncology.

This review assesses the current literature on COVID-19's effects on male sexual and reproductive health, highlighting significant research gaps and providing guidance for patient counseling.

Testosterone may both worsen and protect against COVID-19 effects in men.

This article reviews the impact of aging and related urologic conditions on male fertility, highlighting the effects of various treatments on sperm parameters and recommending pre-treatment counseling for fertility preservation. It reports no new clinical results.

This review examines the impact of biotin, vitamin B12, and zinc on male reproduction, emphasizing their role in spermatogenic failure, but reports no new clinical results.
