Original article is here (paywalled 😑). Not sure how far to take these results with such a tiny N but interesting if it can be replicated with a larger sample size. It looks like they initially hypothesized that HRT had caused the changes but ended up rejecting that idea in favor of it being the voice training.

  • Thanks for the info, I didn’t know that. Since voice training more/less got me to where I wanted to go, this isn’t something that I researched all that well.

    Thankfully this isn’t an opinion I’ve shared at all outside of this thread, but I’ll make sure not to contribute to the stigma going forward nonetheless.
