INTRODUCTION: No study has ever systematically evaluated the impact of varicocele on sexual function. AIM: Two cross-sectional studies were performed in patients attending an andrology unit either for male sexual dysfunction (study 1) or couple infertility (study 2). In study 1, we evaluated the impact of varicocele on sexual function. In study 2, we retrospectively evaluated a possible association between varicocele and prostatitis signs and symptoms. METHODS: Study 1 refers to a consecutive series of 2,448 (mean age 52...

Diabetic autonomic neuropathy (DAN) is a serious and common complication of diabetes. Despite its relationship to an increased risk of cardiovascular mortality and its association with multiple symptoms and impairments, the significance of DAN has not been fully appreciated. The reported prevalence of DAN varies widely depending on the cohort studied and the methods of assessment. In randomly selected cohorts of asymptomatic individuals with diabetes, approximately 20% had abnormal cardiovascular autonomic function...

The authors examined a 48-year-old man with a history of hypertension (6 years) and a history of erection and ejaculation during cold exposure and confrontation with fear (20 years). Exposing the foot to cold water induced ejaculation in 10 seconds. A variety of antihypertensive medications resulted in control of hypertension, without improvement in ejaculatory dysfunction. Similarly, prazosin controlled the blood pressure, but not the episodes of ejaculation. Treatment with reserpine resulted in gradual reduction in blood pressure and an improvement in ejaculatory dysfunction...

Imaging methods are essential in the diagnosis of erectile dysfunction. With sonography the penile cavernous tissue and the deep arteries can be shown. This visualization is optimized by high-resolution ultrasonography with pulsed Doppler spectrum analysis or angiodynography. Pharmacocavernosonography combined with pharmacocavernosometry is the method of choice to verify pathologic venous leakage from the penis. Phalloarteriography is absolutely necessary before surgery for revascularization of the penis. In investigations of fertility sonography of the scrotum only plays a subordinate role, as an occlusion of the epididymis cannot be diagnosed in this way...

Experimental work in animals has shown that both methyldopa and clonidine lower the blood pressure predominantly by an action on the central nervous system. This action is due to alpha-adrenoceptor stimulation by clonidine and by alpha-methyl-noradrenaline. The evidence for a central site of action for these drugs in man is indirect but persuasive. Both drugs lower blood pressure and heart rate without causing much postural or exercise hypetension. Sympathetic responses like the overshoot of pressure following Valsalva's manoeuvre are reduced but not abolished...
