This pilot study investigates the regular use of non-invasive dorsal genital nerve stimulation (DGS) for the treatment of female sexual dysfunction (FSD). The researchers aim to determine whether subjects with FSD can correctly follow an at-home treatment regimen and to demonstrate that DGS can improve FSD arousal symptoms in premenopausal and postmenopausal women. Some subjects will use a smart vibrator for comparison to DGS.
