[Behavioral treatment of functional anejaculation and factors influencing the therapeutic effect].

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.
