Most men seeking penile enhancement techniques have a normal penile size. They are either misinformed or suffer from penile dysmorphophobia and should be discouraged from undergoing invasive procedures. Less invasive techniques including penile extenders are not associated with major complications and may be beneficial from a psychological perspective.
We conducted this study to assess the efficacy and safety of AndroPenis (Andromedical, Madrid, Spain) penile extender.
Between December 2010 and December 2013, 163 men presented to our institution complaining of small penile length and/or girth. All patients received structured psychosexual counseling. Fifty-four patients were willing to use the AndroPenis penile extender after counseling. Patients with major psychiatric disorders were excluded from enrollment. The patients were instructed to wear the device between 4 and 6 hours per day for 6 months. Penile dimensions including flaccid stretched and erected lengths were measured at baseline and after 1, 3, 6, and 9 months. Erectile function was assessed at baseline and 9 months after treatment using the simplified International Index of Erectile Function (IIEF-5). An institutional nonstandardized questionnaire was used to evaluate patient satisfaction at the end of study.
Penile length and girth enhancement as well as satisfaction rate and improvement in erectile function were assessed during follow-up.
At 6-month follow-up, a mean gain of 1.7 ± 0.8, 1.3 ± 0.4, and 1.2 ± 0.4 cm was noted for the flaccid, stretched, and erected penile lengths, respectively (all P values < 0.001). During the off treatment period, there were no significant changes in penile lengths. No effect on penile girth was observed. Patient satisfaction survey revealed modest satisfaction. From 13 patients with mild baseline erectile dysfunction, nine patients reported normal erectile function after 9 months.
Penile extender as a minimally invasive technique is safe and provides modest benefits and patient satisfaction.
大多数寻求阴茎增强技术的男性阴茎大小正常。他们要么信息有误，要么患有阴茎畸形恐惧症，应劝阻他们进行侵入性手术。侵入性较小的技术，包括阴茎延长术，与主要并发症无关，从心理角度来看可能是有益的。
我们进行这项研究是为了评估 AndroPenis（Andromedical，马德里，西班牙）阴茎延长器的疗效和安全性。
2010 年 12 月至 2013 年 12 月，163 名男性因阴茎长度和/或周长小而到我院就诊。所有患者均接受了结构化的性心理辅导。在辅导后，54 名患者愿意使用 AndroPenis 阴茎延长器。患有严重精神障碍的患者被排除在研究之外。患者被要求每天佩戴该设备 4 至 6 小时，持续 6 个月。在基线、1、3、6 和 9 个月时测量阴茎尺寸，包括松弛伸展和勃起长度。使用简化国际勃起功能指数（IIEF-5）在治疗后 9 个月评估勃起功能。在研究结束时，使用机构非标准化问卷评估患者满意度。
在随访期间评估阴茎长度和周长的增加、满意度以及勃起功能的改善。
在 6 个月的随访中，松弛、伸展和勃起的阴茎长度分别平均增加了 1.7±0.8、1.3±0.4 和 1.2±0.4 厘米（所有 P 值均<0.001）。在停药期间，阴茎长度没有明显变化。阴茎周长没有变化。患者满意度调查显示满意度适中。在 13 名基线轻度勃起功能障碍的患者中，9 名患者在 9 个月后报告勃起功能正常。
作为一种微创技术，阴茎延长术是安全的，可以提供适度的益处和患者满意度。
