In this study, autologous intratesticular PRP injection was found to be a feasible and well-tolerated procedure with low complication rates and quick recovery, but the authors indicated that current evidence is insufficient to confirm its effectiveness for mTESE.

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 randomized study of male contraceptive regimens, adding finasteride did not significantly enhance spermatogenesis suppression compared to the control group.

This case report documents the first use of clomiphene citrate to potentially improve fertility in a man taking finasteride, highlighting sperm count issues associated with the medication.

This study confirmed that an injectable implant known as RISUG-PH™, when administered via the vas deferens, successfully delivers the drug Finasteride to the prostate in male rats for up to 28 days, suggesting a potential localized alternative to oral delivery methods.

Seminal bacteria can lower sperm quality in subfertile men.

This study found that chronic administration of dutasteride in rats did not affect spermatogenesis or oxidative stress in the testes, although it altered hormone levels.

In this study, researchers found that both the EU-TIRADS and Bethesda systems exhibited high specificity but suboptimal sensitivity for predicting thyroid nodule malignancy in patients who underwent surgery, with Bethesda system showing particularly high specificity in this postoperative population.

This study found that vitamin A treatment in rats reduced hyperplastic-dysplastic changes and sebaceous gland hypertrophy associated with 3,4-benzpyrene-induced tumors.

This review found an increasing trend in research on sperm DNA fragmentation over the past 20 years, especially focusing on lifestyle factors, asthenozoospermia, and varicocele, with the TUNEL technique as a predominant method.

This study found that finasteride administration in hamsters led to significant spermatogenesis reduction and seminiferous tubule atrophy compared to the control group.

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.

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

A thorough initial check-up is essential before sperm banking to ensure the best chance of preserving good quality sperm.

This review discusses various substances that can impact male fertility and stresses that products should be confirmed 'sperm-safe' through rigorous testing, not assumptions; it reports no new study results.

In this review, the authors found no evidence of harmful pregnancy outcomes from exposure to finasteride, and report that handling the medication poses negligible risk to a fetus.

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.

This study examined extracts from the heartwood of Kouyousan trees for anti-termite activity against Japanese termites. The researchers reported that cedrol showed strong anti-termite effects, with feeding deterrent activity at low concentrations and lethal effects at high concentrations, while isoabienol mainly contributed to feeding deterrence.

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 found that stem cell transplantation effectively reduced acute inflammation-induced testicular damage, suggesting potential for cell-based therapies in addressing male infertility.

This study suggests that a mild intramuscular dose of botulinum toxin improved spermatogenesis and sperm parameters in ageing mice.

This study reported that in the California Ground Squirrel, certain elements bioaccumulate in hair, providing baseline data for environmental health assessments.

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 found that overexpression of the enzyme SSAT in a mouse model significantly reduced prostate tumor size and progression, suggesting it could be a promising strategy against prostate cancer.

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 article reviews the effects of various medications on male fertility, noting that while commonly used drugs can mostly have reversible impacts, conclusive human evidence remains limited.
