Kate Winslet, 48, reveals she had testosterone replacement therapy to boost her sex drive

Kate Winslet isn’t shying away from a little bedroom confession.

The “Titanic” star, 48, revealed she underwent testosterone replacement therapy to boost her libido.

“Sometimes women have a real dip in libido because there might be stuff going on with their thyroid,” she said during Friday’s episode of the “How to Fail” podcast as she offered advice for one listener looking to revamp their sex life.

“There could also be stuff going on with your level of testosterone.”

“A lot of people don’t know this, but women have testosterone in their body, 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,” added Winslet, who tied the knot with husband Edward Abel Smith in 2012.

The actress also assured the caller that “it’s not [her] fault” for the changes women’s bodies go through.

“Our bodies are weird and they behave in strange ways especially as we get older,” she said.

She also cautioned the listener that the dip in hormone levels could be playing a bigger role in her feelings around intimacy, saying she should “definitely” get her levels checked.

Despite the inevitable changes to women’s bodies over time, Winslet said there are many positives that come with age.

“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,” she shared, adding, “I say to my friends all the time, ‘You look amazing, you look great.'”

She echoed a similar sentiment in her September interview with Harper’s Bazaar UK, telling the outlet she thinks women “get more beautiful as they get older.”

“Our faces become more of who we are, they sit better on our bone structure, they have more life, more history,” she told the magazine.

“I also have learned it’s important to take care of yourself from the inside — not just how you eat and look after yourself from a nutritional standpoint, but how you look after yourself from a mental wellness standpoint; how you feel about yourself emotionally, physically, your place within the world, how you walk through the world, how you live with integrity and sincerity.”
