Impotent men could be helped by an erection-tracking sensor that fits on their penis like a ring.
Developers claim the device, which connects to an app, monitors a man's nocturnal erections to asses the health of their member.
It is hoped the gadget, set to cost £50 when it goes on sale next April, could help the millions of men who suffer from erectile dysfunction by uncovering the root cause of their member malfunction.
Men generally experience three to five erections per night, lasting about 45 minutes in total.
These erections help keep the penis healthy by occasionally flushing the organ with blood during the night.
If a man has under three erections a night it could indicate he has a cardiovascular health problem, that is, a problem with his circulation, or another condition such as diabetes.
A sensor that fits around the penis like a ring promises to help men get to the root cause of impotency by measuring the length, in time, of their nocturnal erections. In use, a man will put the Adam Sensor (left) on their penis before going to sleep. The sensor will then measure the number and duration of nocturnal erections and send this information to the man's phone (right) where it is recorded by an app. The app then creates a report of the night's erection activity for the man to view the in the morning

If untreated, reduced blood flow to the penis can eventually cause internal tissues inside the organ to scar, further restricting blood flow, creating a viscous cycle that sees erectile dysfunction get progressively worse.
But if men are suffering from erectile dysfunction, also called impotence, but having a normal number of erections while asleep, this could suggest the issue is mental.
Helping men uncover which issue might be causing their impotence, and tracking improvements over time, is the aim of the new gadget, called the Adam Sensor.
Men using the device would slip on the sensor so that it fitted like a ring, attached by a strap, around the base of their penis before going to sleep.
The product is designed to be 'small, compact and completely non-obstructive', and according to the developers, men will not even know its there after a few minutes.
They are recommended to wrap a loose dressing around their penis before attaching the sensor however.
Once the man is asleep, the Adam Sensor will track how often the penis engorges with blood, and for how long.
It then wirelessly communicates this information to the Adam Sensor app on the man's phone.
Upon waking up the man then turns off the measurement and then removes the sensor, at which point the app creates a report about the night's erection activity.
Marinos Alexandrou director and co-founder of telemedicine company Adam Health, told MailOnline that while not being to have an erection has an obvious impact on your sex life, it could also be a critical warning sign about your health.
'If you are unable to achieve or maintain adequate erections it may indicate the presence of an underlying medical condition,' he said.
Mr Alexandrou said there were broadly speaking, two types of erectile dysfunction men could experience.
'In broad terms, "physical" or organic erectile dysfunction derives from a reduction in the blood flow in the penis caused by damage to the wall of the penile arteries,' he said.
'As a consequence, all erections are affected by this.'
But, he explained, this erectile dysfunction could also be caused by mental problems, also called psychogenic.
'In the case of psychogenic erectile dysfunction, things like performance anxiety can cause a temporary reduction in the blood flow to the penis and this causes a lack of erection,' he said.
'Typically patients complain of a lack of erections when they are trying to engage in sexual intercourse while nocturnal erections are normal.'
This is where the Adam Sensor comes in, Mr Alexandrou, explained, by helping men determine the cause of their erectile dysfunction it can help get them the right treatment quicker.
'By assessing the quality of nocturnal erections, the Adam Sensor will be able to identify if the erectile dysfunction is due to psychogenic or organic causes,' he said.
'Patients with psychogenic erectile dysfunction are most likely to be better
