[Clinical application of penile biological vibration threshold for precise use of 5% lidocaine cream to treat hypersensitive premature ejaculation].
Zhonghua Nan Ke Xue = National Journal of Andrology 2023 October
OBJECTIVE: This study aimed to evaluate the efficacy and safety of applying 5% lidocaine cream to the sensitive area of the glans penis after its precise localization under the penile biological vibration threshold test for the treatment of primary premature ejaculation.
METHODS: Eighty patients diagnosed with primary premature ejaculation in an outpatient setting were included in this study. They were randomly scored into two groups. Group 1 (n = 40) was given 1 ml of 5% lidocaine cream on demand. They were instructed to apply the lidocaine cream evenly in a circular pattern to the glans penis without precise application to the sensitive area of the glans penis. The treatment lasted for a total of 4 weeks. Group 2 (n = 40) had a penile biological vibration threshold test performed to detect loci with a lower threshold. They were instructed to apply 1 ml of 5% lidocaine cream to the sensitive loci on the glans penis for 4 weeks. Lidocaine cream was applied topically or uniformly to the glans penis 20 minutes before planned intercourse in both groups .The efficacy and side effects before and after treatment were evaluated by the intravaginal ejaculation latency (IELTs) before and after treatment, combined with the Arabic Index of Premature Ejaculation and IIEF-5 score.
RESULTS: After treatment, IELTs in both groups were significantly improved compared with those before treatment(P<0.05);The Arab premature ejaculation index and IIEF-5 score of the precise smear group are higher than those of the uniform smear group(P<0.05).
CONCLUSION: This study infers that applying lidocaine according to the threshold of penile and glans vibration has a positive effect and fewer adverse event reports compared with the traditional method of using surface anesthetics, which is worthy of clinical promotion.
