100 Women: Rebecca Gomperts and the abortion ship
23 October 2013 Last updated at 08:17 BST
Dutch doctor Rebecca Gomperts is no stranger to controversy through her work with her organisation, Women on Waves.
She sails into countries where abortions are illegal and provides the abortion pill to women who wish to terminate their pregnancies.
She believes the work she does saves women's lives. But she has encountered strong opposition from pro-life groups and governments - including facing down warships when her yacht approached Portugal.
On Friday 25 October Rebecca Gomperts will be at the BBC as one of those taking part in our 100 Women conference.
