Persistent Sexual Arousal Syndrome (PSAS) is the name that previously used for Persistent Genital Arousal Disorder. PSAS results in spontaneous, persistent genital arousal that cannot be controlled. It is not connected to sexual desires. It may also include genital engorgement and orgasm.
The condition was first documented by a doctor in 2001. It is considered to be unique to women. The male counterpart is known as priapism. While priapism is listed in the DSM-IV, PSAS (or PGAD) is not.
The condition is sometimes mistakenly linked to hypersexuality or thought to be enjoyable when in actuality, PSAS can interfere with the patient's ability to work, drive, and function in public.
