Persistent genital arousal disorder is described in a spontaneous, persistent, and uncontrollable genital arousal in women, with or without orgasm or genital engorgement, unrelated to any feelings of sexual desire. This study aimed to argue that application of Botulinum toxin in the periclitoral region in order to block the dorsal nerve of the clitoris might decrease symptoms of persistent genital arousal disorder. The authors presented 2 cases, in which application of Botulinum toxin resulted in improvement of the symptoms of persistent genital arousal disorder. Botulinum toxin type A treatment protocol is seen as a promising application for the persistent genital arousal disorder. However, further controlled studies in large samples are needed.
Nazik et al. (2013) studied this question.
