Scientists believe that this is an alternative to a vasectomy. This product is flexible and contracts and expands as needed. It also functions on its own radio frequency so that there is no chance of it opening and closing without the man’s knowledge.
Another “advantage” is that it does not require surgery to complete. Doctors at a clinic could easily perform the procedure by inserting it in with a hypodermic needle. Yikes, I don’t know if my husband would consider that an “advantage.” LOL!
