Psychotectic treatments were medical procedures in the course of psychotectic therapy. They were used by the androgynous J'naii to eliminate all psychological elements of gender identity in the rare cases when that was deemed necessary.
It was commonly considered as help among J'naii, as people forced through it said they were grateful for it. As such, the therapy appeared to be a form of mind control, as it reversed the personal attitudes towards the deviant gender from natural and wonderful to sick and terrible. If the individual was unwilling to admit having the urges, the treatments might not be successful.
In 2368, a J'naii shuttle pilot named Soren was forcibly given psychotectic therapy after expressing a female gender identity and an attraction to USS Enterprise-D first officer William Riker. After the therapy, Soren claimed to be amazed to not have noticed the sickness of the deviant condition, and was sorry for Riker, who had fallen in love with the J'Naii. Soren did not express any desire to be female again. (TNG: "The Outcast")
