Abstract

Purpose

There are no approved drugs or devices for the treatment of intravaginal ejaculation disorders, and treatment is often difficult. This study aimed to evaluate the efficacy and safety of the A10 Cyclone SA + PLUS® ejaculation aid (Rends Co., Ltd., Chiba, Japan), which allows the user to adjust the intensity of stimulation, for intravaginal ejaculation disorders.

Methods

Each participant was instructed to perform practice masturbation with the A10 Cyclone SA + PLUS to simulate vaginal ejaculation. After 8 weeks of training, the participants were asked about their intravaginal ejaculation status. Sexual function was also evaluated before and after the training using several specific questionnaires, including the numerical rating scale for ejaculatory satisfaction.

Results

Among the 10 participants (41.5 ± 3.21 years) who completed the training and questionnaire evaluation, four (40%) became capable of intravaginal ejaculation. The questionnaire evaluation showed predominant improvement after training in the ejaculation-capable group according to the numerical rating scale, which expresses satisfaction with ejaculation. The participants experienced no significant adverse events.

Conclusion

As no effective treatment currently exists for intravaginal ejaculation disorders, we conclude that the A10 Cyclone SA + PLUS may be one treatment tool for intravaginal ejaculation disorders with good efficacy and no adverse events.
