The innovations saving women's lives

BBC 100 Women names 100 influential and inspirational women around the world every year.

In 2017, we're challenging them to tackle four of the biggest problems facing women today - the glass ceiling, female illiteracy, harassment in public spaces and sexism in sport.

With your help, they'll be coming up with real-life solutions and we want you to get involved.

Let these three successful innovations inspire you and then share your ideas. Find us on Facebook, Instagram and Twitter and use #100Women
