Sexsomnia: A case of sleep masturbation documented by video-polysomnography in a young adult male with sleepwalking

The first case of video-polysomnography (vPSG) documented sleep masturbation in a male is reported, and the second reported case of shift work induced sexsomnia. A 20 y.o. soldier with childhood sleepwalking (SW) developed sleep masturbation and SW triggered by military shift work. vPSG documented two episodes of sleep masturbation from N2 sleep in the fourth sleep cycle and from N3 sleep during the fifth sleep cycle. There was no sleep-disordered breathing nor periodic limb movements. vPSG thus confirmed confusional arousals from NREM sleep as the cause of the masturbation. Bedtime clonazepam therapy controlled the SW but not the masturbation.
