Scientists have invented a machine that can measure how randy you are feeling.

The gadget, dubbed the hornometer, calculates whether a person feels sexy by studying electrical activity in the brain.

Patients are asked to watch erotic videos along with films of a non-sexy nature reports The Sun.

Electrodes attached to their heads read the electrical responses to the various images. A computer analyses the data to measure the patient’s libido.

The machine was invented by a team at Rambam Hospital in Haifa, Israel.
