There is renewed hope that a male contraceptive pill could one day come to fruition.
A drug trial of 40 participants has found that taking a pill once a day reduces the production of sperm and testosterone with no significant side-effects.
It comes after years of research to find an alternative to condoms and vasectomies. While a female contraceptive pill has been available for around 70 years, a male alternative has never been found.
Nanogirl Michelle Dickinson told Francesca Rudkin that it is actually very difficult to create such a pill, but this study has found a new to analyse that pill that could lead to a break through.
However, despite the recent breakthrough, a pill is unlikely to be readily available for another 10 years.
