Is rhino horn used for erectile dysfunction?

Could you clarify if rhino horn is indeed utilized as a treatment or remedy for erectile dysfunction? It's an intriguing notion, but I'm curious if there's any scientific evidence to support this claim. Is there any research indicating that rhino horn has any medicinal properties specifically related to improving sexual function? Additionally, given the ethical and conservation concerns surrounding rhino horn trade, is there a more ethical and sustainable alternative for addressing erectile dysfunction?
