Hi, thanks for sharing your post and this comment. I do wish that you added that caveat in your post. "The last 3 weeks it started to return." I think that's an important nuance to the situation. Here's a study showing that children who stutter had elevated testosterone levels: [https://pmc.ncbi.nlm.nih.gov/articles/PMC4437599/](https://pmc.ncbi.nlm.nih.gov/articles/PMC4437599/) Your post and that study suggest that there might indeed be an involvement of testosterone in stuttering physiology. The study suggests that too much testosterone might be detrimental for stuttering, so i don't want people to be misled by your post.
