We investigated the effects of Antep pistachio on International Index of Erectile Function (IIEF) scores, penile color Doppler ultrasound (PCDU) parameters and serum lipid levels in patients with ED. A total of 17 married male patients with ED for at least 12 months were included in this prospective study. Patients were put on a 100 g pistachio nuts diet for 3 weeks. IIEF and PCDU were evaluated before and after the pistachio diet. In addition, plasma total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglyceride were measured before and after dietary modifications from all subjects. Mean IIEF-15 score was 36 ± 7.5 before the diet and 54.2 ± 4.9 after the diet (P=0.001). Similarly, an increase in all five domains of IIEF was observed after the diet (P<0.05). Mean peak systolic velocity values before and after the pistachio diet were 35.5 ± 15.2 and 43.3 ± 12.4 cm s(-1), respectively (P=0.018). After the pistachio diet, TC and LDL levels decreased significantly, whereas HDL level increased (P=0.008, 0.007 and 0.001, respectively). We demonstrated that a pistachio diet improved IIEF scores and PCDU parameters without any associated side effects in patients with ED. Furthermore, the lipid parameters showed statistically significant improvements after this diet.
我们研究了开心果对 ED 患者的国际勃起功能指数（IIEF）评分、阴茎彩色多普勒超声（PCDU）参数和血清脂质水平的影响。这项前瞻性研究纳入了 17 名患有 ED 至少 12 个月的已婚男性患者。患者接受了为期 3 周的 100 克开心果饮食。在开心果饮食前后评估 IIEF 和 PCDU。此外，所有受试者在饮食改变前后测量血浆总胆固醇（TC）、低密度脂蛋白（LDL）、高密度脂蛋白（HDL）和甘油三酯。饮食前 IIEF-15 评分为 36±7.5，饮食后为 54.2±4.9（P=0.001）。同样，饮食后 IIEF 的所有五个领域均有增加（P<0.05）。饮食前后的峰值收缩速度值分别为 35.5±15.2 和 43.3±12.4 cm/s（P=0.018）。开心果饮食后，TC 和 LDL 水平显著降低，而 HDL 水平升高（P=0.008、0.007 和 0.001）。我们证明，开心果饮食可改善 ED 患者的 IIEF 评分和 PCDU 参数，且无任何相关副作用。此外，这种饮食后脂质参数有显著改善。
