Seminal vesicles - an overlooked pair of accessory glands in male sexual dysfunction: a narrative review

The seminal vesicles (SVs) have long been recognized for their role in male fertility, yet their contribution to male sexual function is often underestimated. In recent decades, studies have gradually unveiled an association between SVs and various male sexual dysfunctions (SDs), including diminished libido, erectile dysfunction, premature ejaculation, delayed ejaculation, and orgasmic disorder. We conducted a comprehensive literature search of publications up until April 2024 in PubMed, Google Scholar, and CNKI, focusing on original studies, case reports, and reviews addressing the relationship between SVs and male SDs. The aim was to explore the pathophysiological mechanisms, clinical evaluation, and management of this relationship, providing urologists and andrologists with new insights into diagnosing and treating complex male SDs. Current research suggests that SVs may play a role in male sexual function, but the evidence remains limited. Future large-scale, rigorously designed studies are needed to further validate this relationship.
