Has anyone heard about the andro-switch ring before? It is supposed to work without taking any pills and be free of side effects (except for carrying a silicone ring around the testicles). https://www.medscape.com/viewarticle/986261

Looks like you have to wear it for at least 15 hours a day for several months before it's effective..
