功能性不射精症行为治疗模式探索及疗效影响因素分析

Behavioral treatment of functional anejaculation and factors influencing the therapeutic effect

目的:回顾性分析门诊主诉为性行为不射精、但自慰可射精的功能性不射精患者,观察自慰方式改变结合性行为过程中增加视听刺激的改良行为治疗模式对功能性不射精症的疗效,并分析功能性不射精行为治疗的影响因素。方法:选择2019年8月至2021年5月在上海市第一妇婴保健院男科门诊就诊的功能性不射精患者,按行为治疗改良前后分为两组,比较两组患者的疗效差异,研究行为治疗模式改良疗效。研究年龄、禁欲时间变化病程、性行为前禁欲时间、有否采用视听刺激及体位改变、双侧睾丸大小均值以及生殖激素水平,与功能性不射精行为治疗结果的相关性。结果:完成治疗患者共计59例,治疗后性行为中成功射精≥1次的患者有22例(37.29%)。其中改良前行为治疗39例,在治疗后性行为中成功射精≥1次的患者11例(28.21%),改良行为治疗20例,在治疗后性行为中成功射精≥1次的患者11例(55.00%)。改良行为治疗和改良前行为治疗患者的有效率呈现显著差异(P<0.05)。在行为治疗的多个模式中,通过站立位自慰和性行为完成射精的行为治疗模式及行为治疗过程中自慰频率降低与功能性不射精症治疗疗效相关(P<0.05)。结论:采用改良行为治疗模式对功能性不射精患者有一定治疗效果。针对不射精针的先前事件是功能性不射精症行为治疗的关键,因此进一步探索更有效的行为治疗模式将成为功能性不射精行为治疗的发展方向。

Objective:To study the effect of a modified behavioral treatment(MBT)on functional anejaculation and analyze the factors influencing the therapeutic efficacy.Methods:We enrolled in this study 59 men aged 24-45 years visiting the Andrology Clinic of Shanghai First Maternity and Infant Hospital from August 2019 to May 2021 and complaining of aejaculation in sexual intercourse but normally ejaculating during masturbation.Thirty-nine of the patients underwent conventional behavioral treatment(the CBT group)and the other 20 received MBT,namely,changing the masturbation method combined with audiovisual stimulation during sexual intercourse(the MBT group).We compared the therapeutic effects between the two groups of patients,and analyzed the correlation of the outcomes of MBT with age,abstinence duration,use of audiovisual stimulation,change of the sexual position,mean bilateral testis volume and sex hormone levels.Results:After treatment,22(37.29%)of the patients achieved successful ejaculation at least once in sexual intercourse,11(55.00%)in the MBT group,and the other 11(28.21)in the CBT group,with a significantly higher effectiveness rate in the former than in the latter(P<0.05).The effectiveness rate was significantly correlated to the method of standing-position masturbation plus sexual intercourse and reduction in the frequency of masturbation among various strategies of behavioral treatment(P<0.05).Conclusion:MBT has a certain effect on functional anejaculation,and targeting the previous events of the patient is the key to the therapeutic efficacy.Further exploration of more effective strategies of behavioral treatment will become the trend of development in the management of functional anejaculation.
