Does Penile Implant And Lupron Injections Lead To Penile Leak?

An 85-yr. old male has some kind of fluid that seaps from the head of the penis, sometimes in scant quantities during the day and sometimes at night. It's sometimes sticky and sometimes not.

The male has a penile implant that has been there for many years and also gets lupron injections. What are possible causes and treatment? Is this serious?
