It's not the packaging that needs work, its the product. Popular forms of effective male pregnancy prevention are pretty limited. There really hasn't been any innovation in the field in a long time. Really we can launch people into space but we still have to put some sort of poly vinyl silicone sleeve on ding dongs? That's the best it gets?
Pregnancy prevention is not the issue, it's STI transmission that must be prevented, especially in africa.
I doubt we will have a viable substitute for a latex barrier in that regard until some sort of pathogen-hunting nanotechnology becomes mainstream. By that point we may well have transcended our present notions of sex/gender altogether.
