It filters through the uterus,

A breakthrough in fertility treatment could see women conceive while sitting at their desk, running errands or even shopping.

UK company Reproductive Sciences Ltd has produced the Evie pump, which slowly releases sperm over four hours in to the uterus through the cervix.

According to The Telegraph, the holster-like device is worn on the woman's thigh and works to artificially inseminate by filtering sperm through the cervix and in to uterus, mimicking nature.

The slow release method differs from artificial or intrauterine insemination (IUI) that injects prepared sperm directly in to the uterus, Reproductive Sciences said.

'The Evie is akin to a regular catheter setup, however the catheter tube goes into the uterus,' Fertility Factor wrote.

'The catheter is implanted into the uterus at the fertility clinic after being pre-filled with washed sperm, and a button is pressed to activate the tiny disposable pump with a timer attached.

'The device is strapped firmly to the woman's leg, and she can leave the clinic and go home or go about her normal life.'

The device had a 17.5 per cent success rate in clinical trials, and is expected to be released next year (stock image)

The Telegraph reported the device is expected to be released in 2017 and would cost about AUD$965 (£600).

'This device gives women more freedom,' Reproductive Services' David Dally told The Times.

'The catheter is initially inserted by a health professional and then [the patient is] free to leave the clinic, go to work, go home.

'Four hours later they can remove the device themselves. It is a low-cost treatment that requires very little technology.'

At the end of the four hours, women can press another button that injects any leftover sperm.

They can then remove the device at home.

'The catheter is initially inserted by a health professional and then [the patient is] free to leave the clinic, go to work, go home,' Mr Dally said (stock image)

The sperm used in the device goes through a process called 'sperm washing', that separates the semen from the sperm, eliminating any dead or slow-moving sperm.

So how well does it work?

Mamamia reported Evie showed a 17.5 per cent chance of conceiving in clinical trials, compared to the 8.5 per cent success rate of IUI.
