精索静脉曲张 中国就医指南

Varicocele is a common urological and reproductive condition characterized by the abnormal dilation and tortuosity of the pampiniform plexus veins within the scrotum—most frequently on the left side due to anatomical differences in venous drainage. It is essentially a 'varicose vein' of the spermatic cord and represents the most prevalent correctable cause of male infertility, affecting approximately 15% of the general male population and up to 40% of men presenting with primary infertility. Pathophysiologically, varicocele arises primarily from incompetent or absent valves in the internal spermatic vein, leading to retrograde blood flow, venous hypertension, and impaired thermoregulation in the testis. This results in oxidative stress, hypoxia, hormonal imbalance (e.g., reduced testosterone and inhibin B), and disruption of spermatogenesis—manifesting as decreased sperm count, motility, and morphology. While many cases are asymptomatic, symptomatic varicoceles may present with dull, aching scrotal discomfort—often exacerbated by prolonged standing or physical exertion—and may be associated with testicular atrophy or palpable 'bag of worms' on physical exam. Epidemiologically, varicoceles typically develop during puberty, with peak diagnosis between ages 15–35; prevalence increases with age but clinical significance remains highest in reproductive-aged men. Risk factors include tall stature, chronic increased intra-abdominal pressure (e.g., from heavy lifting or constipation), genetic predisposition to venous wall weakness, and connective tissue disorders. Importantly, varicocele significantly impacts quality of life—not only through physical symptoms like pain and swelling but also via psychological distress related to infertility, diminished sexual confidence, body image concerns, and relationship strain. Untreated, it may contribute to progressive testicular dysfunction and irreversible germ cell loss over time. Early detection via clinical examination and confirmed with scrotal Doppler ultrasound is essential. Although not all varicoceles require intervention, treatment is strongly indicated for men with infertility and abnormal semen parameters, palpable testicular atrophy, or persistent pain unresponsive to conservative management. Timely, evidence-based intervention can restore fertility potential in up to 60–70% of cases and markedly improve both reproductive outcomes and patient-reported well-being.
