Actress Lena Dunham is set to be honoured by America's Planned Parenthood group for exploring the issues facing modern women in her Tv show Girls.

Dunham, the creator and star of Girls, will receive the Maggie Award for Media Excellence for promoting frank conversation about sexuality through the series, which centres around four young women living in New York City.

She will be handed the honour at the annual Planned Parenthood dinner in Washington, D.C. on Thursday (25Apr13) and U.S. President Barack Obama will deliver the keynote address.

The organisation provides sexual and reproductive health services to women across the U.S.
