Oscar-winner Jane Fonda has revealed the secret behind how she maintains her sex drive in her seventies - testosterone.
The fitness queen dedicated a full chapter of her recent autobiography to love-life advice for the over-seventies.
Fonda said that she had to discontinue the treatment after it gave her acne. Testosterone replacement therapy has been widely criticized in the U.S., with critics saying that the Big Pharma is trying to sell medical solutions to what is effectively a psychological problem.
HuffPost Celebrity has an interview with Fonda, where she talks about her family, getting older and life in "prime time".
