Kate Winslet "knows" undergoing testosterone replacement therapy can boost sex drive

She said: "A lot of people don't know this but women have testosterone in their body, (and) when it runs out, like eggs, it's gone, and once it's gone you have to replace it and that is something that can be done and you'll feel sexy again... I know."

Kate spoke out on the treatment after a listener had asked for help to rediscover their sex drive, with the actress going on to advise them: "I would suggest for your physical self, have your thyroid levels checked and your testosterone levels checked well because those things could have a direct impact on how you're actually feeling.

"It's not your fault - our bodies are weird and they behave in strange ways especially as we get older.

"So there could be a dip in those hormonal levels for you that is contributing much more than you think to how you're feeling about having sex with your boyfriend, so I would definitely go ahead and do that."

When asked how she feels about her body as she ages, Oscar-winner Kate - who appears naked in her new film 'Lee', a biopic of the Second World War photojournalist Lee Miller: "I'm great with it - I think I look flipping amazing. We have to own it, this is the thing.

"We're so conditioned, women, in our 40s to think, 'Oh well, I'm creeping closer to the end'.

"You think you're going into menopause and you'll stop having sex, your boobs are going to sag and your skin's going to go crapey.

"First of all, so what? It's just conditioning. I think women as they get older get juicier and sexier and more embedded in their truth of who they are and more powerful, more able to walk through the world and care less and that is an empowering thing.

"I say to my friends all the time, 'You look amazing, you look great.'"
