Lynn Enright is on a mission to empower women with vital knowledge about their own bodies. Chances are, if you've got one, you've been incorrectly referring to your vulva as a vagina for most of your life.

In her book, Vagina: A re-education, Lynn provides girls and women with information they need about their own bodies - about the vagina, the hymen, the clitoris, the orgasm; about conditions like endometriosis and vulvodynia. It confronts taboos, such as abortion, miscarriage and masturbation, and it tackles vital social issues like period poverty and female genital mutilation.

On today's show, Róisín talks to the journalist and author about the book and why she wrote it.

Also today: Kathy and Róisín discuss Vodafone's new domestic violence policy and the new Women on Walls exhibit at the Royal College of Surgeons.
