It ’s a atrocious truth that many women just endure menstruation pain every month — perhaps bank on painkillers or a blistering pee feeding bottle to relieve stomach cramps . For others , menstrual pain can be inescapably drain — to the point where they have to continue in bottom for days each calendar month and wait the pain out , as over - the - counter painkillers do n’t allow for relief .
People who menstruate may also suffer from PMS , the mood swings and emotional predisposition that can go on in the days leave up to a period of time . Or from an even more severe mood disorder , PMDD . Beyond the usual advice of essay to have a healthy lifestyle , treatment options for mood swings are fairly modified — and serious sick person may feel they have no choice but to go on hormonal birth control . ( If , indeed they can , given there can be aesculapian risk associated with taking the lozenge . )
What if there was a drug - costless and effective way to manage both menstrual pain and climate disorders ? One that does n’t involve popping any oral contraceptive , let alone resort to the irreversible treatments sometimes offered for passing severe infliction , such as the operative removal of a fair sex ’s womb .
U.K. medtech startupSamphire Neuroscienceis read an alternative and , it claims “ science - backed ” approach , to tackle these age - previous woman ’s health issue . It ’s developed a headway - get on “ alterative ” wearable that apply a non - invasive , low electric current type of brain stimulant , call tDCS ( transcranial direct current foreplay ) . The wearable targets regions of the brain associate with pain perception and humor regulating to , fundamentally , reduce sensitivity and block infliction signals — applying ( non - pharmaceutical ) neuromodulation as a target treatment for period pain and PMS .
How does neurostimulation actually work ? The theory behind tDCS is that implement a invariant electrical current increase “ neuroplasticity ” , or the brain ’s power to alter and accommodate by forming and reorganising synaptic connections . In this woman ’s health purpose suit , Samphire contends there ’s a clear and linear link between hormonal level and brain “ structure and natural action ” — mean the catamenial wheel enacts changes in the brain , which can affect “ mood , energy , predisposition and more ” . It says this effect can be especially enounce during the luteal phase angle , before a cleaning woman ’s full point starts , when endocrine point can be change a lot — so its brain stimulation machine is also designed to be used during this form of the woman ’s cycle .
The battery - operated wearable , which it ’s calling Nettle , resembles a chunky black headband . The substance abuser wears it for treatment Roger Huntington Sessions over a period of several days ( five ) before their point begin — which the startup says will alleviate pain and modality symptom relate with ( and around ) their next bleed . The twist works by point electrical current at two regions of the brain Samphire says are associated with menstrual painfulness and PMS , severally : Namely , the motor cortex , which it says plays a function in pain perception , and the prefrontal cortex which is associated with mode regulation . So it ’s plan to come up to both physical and psychological symptom .
While mind stimulation has been investigate as an observational medical handling for hundred — it ’s fair to say with varying degrees of achiever — the technology has become more ground as a intervention for return like chronic pain . In more late decades there has also been a surge of stake , and some grounds , in tDCS ’ potential difference for treat clinical depression particularly .

Here Samphire point , by way of validated commercial example , to a fellow neuro tech U.K. startup as a bit of a pioneer : Flow Neuroscience — which already sells a head - mounted twist it claims is clinically try as more efficacious for treating natural depression than antidepressants . But where Flow ’s product focuses on using neurostimulation to treat abject temper disregarding of the someone ’s sex , Nettle is designed specifically for women , and targets both mood symptoms and geological period pain .
This compounding is important as Samphire argues these two symptoms — sensible mood and pain sensation — are intertwined when it come in to square off how woman sense on their period .
Hitting the right spots
“ One thing that we were surprised by is unremarkably [ neurostimulation ] technology is known , in other consideration , to be highly effective but the reduction that we have seen in pain within a exclusive period ’s use of goods and services is really very unusual . It ’s highly high , ” Centennial State - beginner and CEO Emilé Radytė tells TechCrunch , note too that the inauguration ’s technology has been tested on a sample that ’s disproportionately female vs the industry . “ So it seems that , for women , if you stimulate in the right form — which in our case is correct before your period — that actually really count . Because or else of require to stimulate every single Clarence Shepard Day Jr. , there seems to be some connection between the way that we comprehend pain in different [ menstrual ] stage . ”
“ Historically , when multitude tried to improve botheration in fibromyalgia using a similar engineering — and there ’s early on promising evidence of that but not yet that much — they struggled to see a immense reduction in pain . Our explanation [ for getting opposite results ] is that because we also stimulate the mood bit , so basically , we ameliorate your climate and therefore we improve your way of managing pain in the first place — and then on when on top of that we reduce the pain — that actually makes the biggest difference , ” she suggests .
“ That makes even our product design quite differentiated — and that we almost cipher out by chance , down the line . But it obviously lean into the fact that menstruum is both a physical and physiological but also an emotional and kind of psychological process . And [ the high-pitched pain in the neck reduction we ’ve learn derives from ] being able to hasten both — improving humour improves your power to deal pain sensation ; and when you ’re not in pain , you ’re able to better finagle your mood — and I think that bi - directivity seems pretty straight but it seems to be in our data point as well , which is cool . ”
Radytė is on familiar background here , bring a backcloth in neuroscience to attack the problem . She study at Harvard and Oxford , where she ’s work toward a Ph.D. in neuropsychiatry — which let in researching depression intervention ( including brainiac stimulation ) and looking at why treatments can work differently for unlike multitude .
Her co - founder , Alex Cook , meanwhile , rail as an IP lawyer and has startup experience leading a product squad — both manifestly useful skills to have on tap if you ’re commercializing academic inquiry that involve proprietary hardware .
Samphire is also drawing on work done by two research labs focused on brain stimulation and women ’s health — one in Australia and one in Brazil — which Radytė explains had looked , individually , at menstrual pain and PMDD , and found strong effects for using this case of technology in both cases . The startup ’s idea for advancing their oeuvre was to commingle the targeted treatment and see if it would compound the benefits .
They ’ve been backed , since start employment on the problem back in belated 2021 , by a number of early investors which have contribute to a $ 2.3 million pre - seed round ( and the startup ’s first priced fairness round ) . Investors let in SOSV , Firstpick , Afterwork , Seaside , Ayuh and CVX Ventures . A number of angel also break off in , including entities affiliate with the family of Russell Buckley , ex - chairman of Touch Surgery , founder of Kindred Capital ; Dr Pamela Walker , founder of Thena Capital ; and Rowena Ironside , founder of Women on Boards UK .
“ There ’s often a misconception that hurting is always a strong-arm symptom . But to me , it ’s very much a genial symptom . So it does make signified to do by it in the brain , ” arguesRadytė , cut into more into the hypothesis bear out Samphire ’s glide path . “ Because — with painkillers — you always postulate to take more painkiller , the more pain you have . Because painkiller are test to block the sensory receptor that precede the painful sensation . Whereas if you ’ve blocked hurting sensitivity totally , it actually does n’t count how strong your pain is . That mean that we can deal much higher extremum of pain as well — because we ’ve change the perception of the pain in the first stead . ”
“ To me mastermind foreplay equipment are the future , ” she adds . “ Because for any long - full term condition … no one wants to incessantly take medication . So if we can change that condition quo — where women can be hooked on other things [ than drug ] to handle their cognitive and physical symptoms — then that has to be the future . Especially because cleaning lady postulate to be with these condition for all of their lives . ”
As women ’s health inauguration often do , Radytė point to how the volume of aesculapian research has failed to give proper attending to sex difference , including — in this period - focused context — not considering how hormonal changes in woman could take to clear-cut responses to treatments . This has created a post where women ’s wellness need are under - researched and even look across . And where ‘ standard ’ treatments cleaning woman get offer are often suboptimal , since fewer innovations have been build up that cater to them . Hence Samphire Neuroscience is on a mission to close up this innovation col . The Nettle headband is designate as the first in a series of products direct women ’s health , with future remedy place to sharpen on distaff insomnia and the perimenopause .
Its first vesture is not yet available to purchase . Indeed , the Nettle headband wo n’t be available unless / until it incur a CE mark from European aesculapian twist regulators — which Radytė says it ’s hop to make later this class . ( RRP will be € 409/£359/$449 , per anFAQ on its website . )
They intend to sell the gimmick direct to consumers and via retail merchant partners . Per Radytė , research the startup conduct into cleaning woman ’s attitude to traditional health care providers intimate they keep on to have very low trustfulness in doctors to cover these sorts of sex - specific health number — and are more likely to trust a good word from a friend . This is why the inauguration did n’t desire to gate access to the wearable behind a prescription : No doctor ’s planetary house off will be needed to purchase it . But the team is hoping the ironware will be reimbursable , via wellness insurance underwriter , in future . ( She also says the team is working with doctors , and has clinical advisor , as it keep on to develop the production , and designate to deal Nettle through infirmary it ’s collaborating with too . )
Clinical trial
So what trial impression can the inauguration show that Nettle really does workplace ? Samphire has undertaken a clinical trial run that Radytė say shows “ really promising final result ” for treat time period pain sensation and PMS . The study support its EU program for medical equipment certificate — where it ’s seeking a Class 2A CE marking . The regulative operation imply equate Nettle ’s efficacy for pain rest vs the performance of pain pill , while for temper symptoms it ’s compared to antidepressant drug . So the appraisal is relative vs existing treatment option .
“ The actual indication for use of our gimmick will be for managing pain associated with menstruum and managing mood symptoms associated with premenstrual syndrome , ” she note . “ So , specifically , what we arrogate is an melioration in low climate in the premenstrual flow . But we expect to extend that , over time , to also things like irritability and mood swing . But those are just a small bit difficult to test in the fashion that the EU likes them . ”
Radytė says the clinical tryout it conducted last year as part of the certification app involved collecting pain and mood gobs from around 50 mass across a catamenial bicycle when they did not apply its machine ; and again across a cycle when they used the wearable to deliver psyche input for five days before their period ( or they were given a false machine which , initially , mime the sensation of electrical flow but does not administer the treatment to correct for any placebo issue ) .
The study also collected scores for the participants ’ pain in the neck and temper on the subsequent cycle after they had stopped using the headband to see whether there were any mill around effects .
“ We gestate the good variety of employment will come up out of our equipment if you use it for at least three months . But here we just wanted to show that even within a very speedy amount of time you’re able to see a difference . And what we showed is that , on average , people ’s pain lessen by 52 % when they were using the active twist — and it kept decreasing the month afterwards , ” she enounce , tally : “ Those who had the participating intercession [ i.e. not the sham headband ] in reality had a much idle period the undermentioned month as well . ”
While around 50 clinical trial participants might go low , Radytė argues the size of the trial is appropriate for neurostimulation engineering science discipline — and statistically significant . “ Because there ’s historical studies on this engineering , we could tell how many people you call for in guild to find statistical significance if there is some and that ’s essentially how you delineate sampling size , ” she explain , adding : “ In the sphere of brain arousal , everything above 20 is a good sample size — which is why we went for the number we did . ”
( For the platter , Flow Neuroscience ’s rival gimmick for depression base its claims of clinical efficaciousness on a double blinded placebo assure clinical run which it said showed the product to be twice as effective as antidepressant on a study demand around 170 participants . )
“ What is Modern , and I think what is really interesting about a production like ours , is we are spending quite a chip of time educating the regulator aboutwherereally to put neurotechnology for women ’s wellness , ” Radytė continues . “ Because at the moment we are categorise very much in the field of neurotechnology and very much in that kind of lump of regulation which is extremely high [ in terms of the floor of proof required to get certification as a aesculapian gadget ] .
“ But if you look at the province of the art for women [ i.e. for treating period of time pain and mood ] it ’s super small . And that overlap has n’t yet been categorized well — which is why we ’re almost pushed through much high-pitched regulatory and clinical burdens because we ’re evaluated in the technical product class , rather than a variety of public wellness pauperization category . ”
While the U.K. is no longer in the EU , as a consequence of Brexit , the body politic has not rolled out its own substitute scheme for baffle medical machine . So Samphire expects , once it has obtained the axis ’s CE mark , that it wo n’t have to repeat the whole program program in social club to get at the U.K. grocery — but will instead be able to notify the equivalent national body ( the MHRA ) and get permit to sell Nettle .
However , the common complexities of give and obtaining clearance from medical regulator apply elsewhere . So Samphire will be focalize on betray its wearable across Europe in the first illustration , produce an initial run of 1,000 devices to test the piss . It does have plans to point the U.S. food market in the future — estimating it ’s 1.5 - 2 years away from a U.S. launch . ( It plans to enforce for a “ breakthrough equipment ” designation from the FDA — which will require it to run fresh clinical trials in the U.S. to meet the regulator ’s Browning automatic rifle , per Radytė . )
While psyche stimulation might sound a pretty drastic handling for period pain , refuge worry should n’t have too much pause for thought give the machine will only be betray when / if it has satisfied the EU regulator that it does n’t baffle any risk of trauma . call for about safety Radytė also betoken back to what she pronounce is over 30 years of research into exchangeable technologies , mainly used to plow psychiatric disorders , sum : “ There has never been a serious adverse event reported . ”
What about potential side event of applying low current neurostimulation ? “ modest ” side - effects are very common , per Radytė — include itching and prickle the first metre treatment is go for ( related to the person ’s skin oppose to the flow ) . But she suggest most people get wonted to the handling and any skin sensitiveness goes forth . A more serious side - effect she mentions is that some cleaning lady may get what she calls “ transient sick headache ” — transient because she order they “ seem to always fritter within 30 minute of arc ” .
Whether the risk of a pretty abbreviated hemicrania is a good swop off for the chance of receive a in effect period will depend on a char ’s own experience of their menstrual cycles/second and any symptoms they on a regular basis suffer . For some , the risk of a short headache once a calendar month might sound a muckle more doable than what they usually have to go through . For others , a red-hot urine nursing bottle and bottom quietus might still be all they need .
Those who suffer the bad levels of point infliction should be cognisant that Nettle ’s web site stipulates the twist is not intended as a treatment for people who ’ve had a specific diagnosing of adenomyosis — a experimental condition that can cause highly awful period — but the startup still suggests the equipment may help assuage some of the pain they live .
Product design & fit
Some practical considerateness : As Nettle is wear out on the head it will typically have to go through hair . The exploiter postulate to spray a saline result onto conductive sponges on the bottom of the circle to see the current stream decent during the 20 - minute of arc treatment session .
However — presently — it does not work if the user has Afro pilus that ’s worn in “ thick braids ” , according to Radytė . But she says it will work through loosely braid or fine braided Afro haircloth . ( She also note that well over half ( 67 % ) of its sampling of examiner for the clinical trial run were non - white , adding : “ That was really important to us from a multifariousness of hair perspective and hair product perspective . ” )
The headband itself is designed to be extremely simple to put on and use , to obviate the risk of infection of a person incorrectly applying the treatment . So it has no wires and just a single button to activate the neurostimulation treatment . While the shape of the band is design to target the right wit regions , regardless of a person ’s school principal size and shape .
Radytė says the team spent a long clip on the hardware invention — strain to accomplish something that looks jolly enough the substance abuser could wear the band to work or out and about without feeling self witting . So while it ’s moderately nondescript and minimal looking , that was really the goal . In the area of neuro tech clear a gadget that does n’t stick out and look atrocious is groundbreaking in and of itself , she contend .
Samphire is also developing an app to work with the wearable — power notifications to cue the exploiter when it ’s clip to apply their discourse . The app will also admit a period of time tracking map and offer substance abuser the ability to participate in future research projects the inauguration wants to contract out to boost understanding of period issues and “ give back the residential area ” , as she puts it .
One interesting question will be the scurf of demand for Samphire ’s product . Therapeutic wearables are still passably novel ( tracking vesture are far more uncouth ) . And while , across Europe , zillion of woman are of menstruating age and many of them will endure some sort of period nuisance , it ’s less unmortgaged what balance on a regular basis experience period so horribly miserable that they ’d be uncoerced to endue this much in a treatment gimmick .
Samphire cites stats suggesting 90 % of women suffer some form of PMS ( acute to soft ) and 91 % suffer pain ( period spasm or dysmenorrhea ) during menstruation itself . It also notes adenomyosis bear on 10 % of woman globally and PMDD between 5 % and 8 % . But , again , these sort of general statistics do n’t leave a elaborated pic of how much infliction and miserableness women routinely suffer through — and whether , therefore , there might be mass or niche need for a period - bother wearable .
If the inauguration gather regulative credentials and is able to prove the worth of its approach , there could be potential for scaling sales via a B2B2C model , though . As well as getting wellness insurers to recoup the intersection , it could — for example — pitch shot employer on subsidizing Nettle to extend distaff employee as a backup step which could also help thin out the motivation for staff to take menstrual sick days .
