Rhino horns are modified hair and mammoth tusks are modified teeth so they are very different. But maybe there can be some testosterone in the rhino horns idk.

Rhino horns are modified hair and mammoth tusks are modified teeth so they are very different. But maybe there can be some testosterone in the rhino horns idk. EDIT: It seems you are right, there is some testosterone in hair (https://link.springer.com/article/10.1007/s002160050330 https://link.springer.com/article/10.1007/s002160050330) so probably there can be some amount in rhino horns. I don't know if eating it would have medical effects, for example maybe there's not enough or maybe it's not in the right form or maybe eating it doesn't work.
