I have been using Degarelix for almost a year. Testosterone has not yet recovered three months after the last shot.
Here is a study which reports: "the testosterone levels of most men had recovered to normal by 18-24 weeks after the last LHRHa injection."
I heard that clomid or similar drugs can be used to increase the testosterone level more quickly. You may start with 50mg per day and increase to 100mg.
