轻度勃起功能障碍患者阴茎头部、根部硬度对性交成功率的影响

Effect of hardness of penile head and hardness of penile root on sexual intercourse success rate in patients with mild erectile dysfunction

目的探讨勃起功能障碍(ED)患者阴茎头部、根部硬度对性交成功率的影响。方法选取2022年1月至2023年3月重庆市东南医院及重庆医科大学附属第三医院诊治的200例轻度ED患者作为研究对象。根据国际勃起功能指数-5(IIEF-5)及勃起硬度评分(EHS)分为可完成性生活组(A组)和不可完成性生活组(B组),每组100例。使用RigiScan检测两组阴茎根部、头部硬度及勃起持续时间,分析阴茎头部、根部硬度对性交成功率的影响。结果两组勃起次数、勃起总时间比较,差异无统计学意义(P>0.05);A组阴茎头部硬度≥60%时间、根部硬度≥60%时间及头部、根部周径增大大于B组,A组阴茎头部、根部硬度高于B组(P<0.05);多因素Logistic回归分析显示,头部周径增大(OR=0.800)、根部周径增大(OR=0.828)、头部硬度高(OR=0.653)、根部硬度高(OR=0.725)均是性交成功的保护因素(P<0.05);受试者工作特征(ROC)曲线结果显示,头部周径增大、根部周径增大、头部硬度、根部硬度的曲线下面积(AUC)分别为0.610、0.612、0.676、0.608;Delong分析结果显示,头部硬度AUC显著高于根部硬度、头部周径增大、根部周径增大(P<0.05)。结论阴茎头部周径、根部周径、头部硬度、根部硬度均是性交成功的影响因素,且阴茎头部硬度对性交成功率的影响最大。

Objective To explore the effect of the hardness of penile head and root on sexual intercourse success rate in patients with erectile dysfunction(ED).Methods A total of 200 mild ED patients treated at Chongqing Dongnan Hospital and the Third Affiliated Hospital of Chongqing Medical University from January 2022 to March 2023 were selected as the research subjects.According to the international erectile function index-5(IIEF-5)and erectile hardness scale(EHS),they were divided into complete sexual activity group(group A)and incomplete sexual activity group(group B),with 100 cases in each group.RigiScan was used to detect the hardness and duration of penile roots and heads in two groups,and analyze the effect of penile head and root hardness on the success rate of sexual intercourse.Results There were no significant differences in number of erection and total erection duration between the two groups(P>0.05).In group A,the hardness of penis head≥60%,the hardness of penis root≥60% and the increased circumference of penis head and root increased more than those in group B,and the hardness of penis head and root in group A were higher than those in group B(P<0.05).Multivariate Logistic regression analysis showed that increased head circumference(OR=0.800),increased root circumference(OR=0.828),high head hardness(OR=0.653)and high root hardness(OR=0.725)were all protective factors for successful sexual intercourse(P<0.05).The receiver operating characteristic(ROC)curve showed that the area under the curve(AUC)of increased head circumference,increased root circumference,head hardness and root hardness are 0.610,0.612,0.676 and 0.608,respectively.Delong analysis shows that AUC of head hardness was significantly higher than the root hardness,head circumference and root circumference(P<0.05).Conclusions The circumference of penis head,the circumference of penis root,the hardness of penis head and the hardness of penis root are all influencing factors for the success of sexual intercourse,and the hardness of penis head has the greatest influence on the success rate of sexual intercourse.
