Cambridgeshire police have been trying out a portable device to help women urinate standing up.
The plastic funnel can be used without the need to remove any items of clothing.
The trial was to determine whether the £7.50 Shewee would be useful for the force's 380 female officers if they went out on patrol.
But results showed there was "not a great need" for the gadget, the police force said.
In a Freedom of Information response however, the force said the introduction of the plastic funnels was "still under consideration".
Shewee inventor Samantha Fountain, 33, failed to secure investment when she presented her design on the 2005 series of BBC's Dragons' Den.
The device, which comes in five colours, has since gained widespread popularity among festival-goers, pregnant women and hikers.
