Sexual dysfunction could be a consequence of the Cushing syndrome disorder which occurs due to overproduction of cortisol, especially if it is being treated with glucocorticoids. In this case, aside from increasing energy and mood, among other things, you might feel excessively fatigued, thus reducing sexual interest.

In order to help, it is you who have to manage the cortisol. Do exercise, eat a balanced diet, and reduce stress.
