The menopause currently affects 13 million women in the UK. And yet it's shrouded in secrecy and wildly misunderstood. In this frank and intimate film, broadcaster and journalist Mariella Frostrup shares her own personal experience of the menopause and brings this great taboo out into the open. Mariella investigates how the latest science can explain what it is, and what can be done about it. She meets the scientists who have uncovered the cause of hot flushes and developed a brand new drug to treat them, finds out if taking hormone replacement therapy is dangerous, discovers if men also have a menopause and witnesses a cutting-edge procedure that could actually reverse the menopause. Whatever your age or your gender, the menopause will affect you or someone close to you. It's time we all understood it better.
