A man enrolled in a trial of what may become the first male hormonal contraceptive said it was an opportunity for men to start taking responsibility.

James Owers, a 29-year-old PhD student from Edinburgh, and his partner are one of 450 couples across the UK who will trial the gel.

It contains the hormones progesterone - which is in the female birth control pill - and testosterone.

Progesterone stops the testicles from producing sperm while the testosterone replenishes stores of the male sex hormone which fall as fertility is reduced.

Mr Owers said it takes just 30 seconds each day to put on and that he was keen to help develop more options for men.
