Developed by Samphire Neuroscience, a neurotechnology company based in London, this device leverages recent findings that show hormonal fluctuations during the menstrual cycle can alter brain activity, structure, and function. By harnessing the brain-cycle connection, Samphire has adapted a technique once limited to specialised clinics into an at-home wearable device that goes by the name Nettle. 

This approach reprogrammes how the brain perceives symptoms and offers a medically certified and clinically tested solution that outperforms traditional treatments.

The impact of menstrual symptoms on quality of life

Over 90% of females of reproductive age will experience mild to acute premenstrual symptoms at least once in their lifetime and up to 91% suffer from period cramps (dysmenorrhea) during menstruation. Severe menstrual cramps, in addition to the mental and physical symptoms during the luteal phase (the 5-10 days before your period), are a monthly ordeal many women know well. Studies indicate these symptoms have a negative impact not only on quality of life but amount to nearly nine days of lost productivity per year, costing the UK economy approximately £118 billion annually.
