Exploratory Identification of Seminal Plasma tsRNAs in Sertoli‐Cell‐Only Syndrome Reveals a Pathogenic tRF‐1:31‐Gly‐TCC‐2/ZMPSTE24 Axis

Andrologia, Volume 2026, Issue 1, 2026.
Background Sertoli‐cell‐only syndrome (SCOS), the most severe form of nonobstructive azoospermia (NOA), is characterized by a complete absence of germ cells and a silent testicular microenvironment. Whether seminal plasma can mirror this pathological silence and reflect testicular spermatogenic failure remains an open question.

Testicular Compartment Syndrome Post Bilateral Microdissection Testicular Sperm Extraction: A Case Report and Review of the Current Literature

Case Reports in Urology, Volume 2026, Issue 1, 2026.
Background Testicular compartment syndrome (TCS) is a rare phenomenon with around 14 cases reported in the literature. It occurs when extraluminal compression or increased venous resistance leads to raised intratesticular pressure. The fibrous tunica albuginea covering the testes does not distend, meaning the pressure is not relieved and compartment ...
