Persistent genital arousal disorder (PGAD), originally called persistent sexual arousal syndrome (PSAS), Weiss Disease, and also known as restless genital syndrome (ReGS or RGS), results in a spontaneous, persistent, and uncontrollable genital arousal, with or without orgasm or genital engorgement, unrelated to any feelings of sexual desire. It was only recently characterized as a distinct syndrome in medical literature with a comparable counterpart increasingly reported by men. Though It was studied as far back as 1986 and in the 90s was researched by the Dutch
Some physicians use the term persistent sexual arousal syndrome to refer to the condition in women; others consider the syndrome of priapism in men to be the same disorder. Priapism was a recognized, diagnosable medical condition in the Diagnostic and Statistical Manual of Mental Disorders IV, whereas PGAD was not. With the release of the DSM-5 in 2013, PGAD was again not included as a listed condition.
In particular, it is not related to hypersexuality, sometimes known as nymphomania or satyriasis. (Hypersexuality, nymphomania, and satyriasis are also not recognized diagnosable medical conditions by the DSM-IV).
Physical arousal caused by this syndrome can be very intense and persist for extended periods, days or weeks at a time. Orgasm can sometimes provide temporary relief, but within hours the symptoms return. The return of symptoms, with the exception of known triggers, is sudden and unpredictable. Failure or refusal to relieve the symptoms often results in waves of spontaneous orgasms in women and ejaculation in men. The symptoms can be debilitating, preventing concentration on mundane tasks. Some situations, such as riding in an automobile or train, vibrations from mobile phones, and even going to the toilet can aggravate the syndrome unbearably causing the discomfort to verge on pain. It is not uncommon for sufferers to lose some or all sense of pleasure over the course of time as release becomes associated with relief from pain rather than the experience of pleasure. Some sufferers have said that they shun sexual relations, which they may find to be a painful experience. The condition may last for many years and can be so severe that it has been known to lead to depression and even suicide.
