In the original published version of this article, the authors omitted information on why verbal consent was obtained for participants instead of written consent.
The original statement in section ‘5.1. Study design and participants’ is below:
In this open-labeled study, 10 PRHPs (Table 1) were enrolled during the A-league season. The PRHPs were not using other topical treatment in the pubic area or oral pain reduction therapy prior to the beginning of the study and did not have any ongoing infectious diseases. PRHPs involved in the study started agonistic activity around the age of 4 years and they all started to have AP at the beginning of their professional activity, around the age of 17 years. Before study start, verbal informed consent was obtained from all participants. In addition, the participant involved in the case study consented to publish his individual details. The study was conducted in accordance with the Declaration of Helsinki and the principles of Good Clinical Practice. Owing to its design and population, the present study did not require approval of an ethics committee.
This statement has been updated to include information on why verbal consent was obtained instead of written consent.
