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.
