You Say he was on Orgovyx And prednisone, But that is not a normal combo. Prednisone is mainly used when somebody is also on abiraterone (Zytiga). Testosterone should come back within 90 days after stopping Orgovyx. Was he also on abiraterone? The drug Could make it take nine months to a year or more before testosterone comes back, Even longer in some people.

As others say you need to find out what the testosterone level is.
