Neurophysiological and psychological assessments revealed distinct profiles: Compared to controls, Group A exhibited significantly prolonged latencies in PSSR (P\u2009&amp;lt;\u2009.05), DNSEP (P\u2009&amp;lt;\u2009.05), and GPSEP (P\u2009&amp;lt;\u2009.05), along with significant ejaculatory dysfunction and elevated scores for ejaculation-related distress, anxiety, and depression (P\u2009&amp;lt;\u2009.05). Group B similarly demonstrated extended PSSR latency (P\u2009&amp;lt;\u2009.05) and compromised ejaculatory performance with increased distress and depression (P\u2009&amp;lt;\u2009.05), though their DNSEP and GPSEP latencies and anxiety levels remained comparable to controls. Crucially, while Groups A and B showed equivalent PSSR parameters and comparable distress\/depression severity, Group A displayed significantly longer DNSEP and GPSEP latencies (P\u2009&amp;lt;\u2009.05), worse ejaculatory performance (P\u2009&amp;lt;\u2009.05), and more pronounced anxiety (P\u2009&amp;lt;\u2009.05), suggesting a more extensive neurophysiological disorder in complete anejaculation cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Implications<\/jats:title>\n                    <jats:p>This study applied electrophysiological testing in patients with anejaculation, supporting its potential value as an objective assessment tool and suggesting that impaired neural conduction may represent a possible underlying cause.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Strengths and Limitations<\/jats:title>\n                    <jats:p>This study is among the few pioneering investigations that have applied electrophysiological testing in patients with anejaculation, demonstrating its clinical application value. However, due to the single-center design and relatively small sample size, the generalizability of the findings is limited, and further exploration of the underlying pathophysiological mechanisms is
