The Men's Training Cup Keep Training: A Masturbation Aid Improves Intravaginal Ejaculatory Latency Time and Erection Hardness Score in Patients Unable to Delay Ejaculation

The study examined the effectiveness of the Men's Training Cup Keep Training (MTCK), a masturbation aid, in helping patients who struggle to delay ejaculation. Initially, 37 patients were enrolled, but only 18 completed the study. After an 8-week training period with the MTCK, the intravaginal ejaculatory latency time (IELT) significantly increased from 103.91 seconds to 232.10 seconds. Additionally, scores on the Premature Ejaculation Diagnostic Tool, Difficulty in Performing Sexual Intercourse Questionnaire–5, and Erection Hardness Score also significantly improved. The study concluded that the MTCK may be beneficial for delaying ejaculation and could also improve erectile function. However, the study's limitations include a small sample size, lack of a control group, and absence of long-term follow-up.
