## TL;DR

This study compares hyaluronic acid and botulinum toxin injections for treating premature ejaculation, finding hyaluronic acid more effective.

## Contribution

A direct comparison of hyaluronic acid and botulinum toxin injection efficacy for premature ejaculation treatment.

## Key findings

- Hyaluronic acid injection increased intravaginal ejaculation latency time (IELT) from 1.23 to 7.3 minutes.
- Botulinum toxin increased IELT from 1.78 to 3.87 minutes.
- Hyaluronic acid showed significantly greater improvement in IELT compared to botulinum toxin.

## Abstract

The aim of the study was to assess safety and efficacy of botulinum-A toxin (BTX) injection into the bulbospongiosus muscle versus hyaluronic acid (HA) gel injection in glans penis for treatment of premature ejaculation (PE). The patients were randomly divided into 2 groups. Group a (n = 30) were injected with botulinum toxin type a injection in bulbospongiosus (BS) muscle at the perineum (25 units on each side). Group b (n = 30) were injected with 2 ml hyaluronic acid along the corona (proximal part) of the glans penis and frenulum. The mean IELT significantly increased from 1.78 min to 3.87 min after the BTX injection while the mean IELT was significantly increased to 7.3 min from 1.23 min before injection among the hyaluronic acid injected group (p < 0.001). The improvement of IELT was more significantly noted in the HA group than BTX group by the end of treatment. Both modalities provided a well- tolerated potential treatment in the management of PE with, HA demonstrating a higher efficacy than BTX. More high-quality, randomized prospective studies and the standardization of the inclusion criteria and the outcome assessment methods are needed in order to confirm these findings.
