Jane Fonda’s sexy glamour knocked everyone’s socks off when she appeared in Barbarella in 1968. Now 73, the actress credits her continued good looks in part to a still-strong libido, according to the Telegraph. And how does she keep it so strong?

Well, she’s had a little boost from a surprising source: testosterone. In an interview, she tells the Telegraph: “Here's something I haven't said publicly yet: I discovered testosterone about three years ago, which makes a huge difference if you want to remain sexual and your libido has dropped.

“Use testosterone. It comes in a gel, a pill or a patch.”

But she adds: “I had to stop because it was giving me acne. It's one thing having plastic surgery, but it is quite another to have adolescence acne. That is going too far.”
Fonda has dedicated a chapter of her autobiography, “Prime Time,” to offering tips to seniors to improve their sex lives.

The testosterone advice may prove yet another controversial moment in Fonda’s public life—it’s used in the UK for women who have had their ovaries removed, but in it’s not so readily accepted in the U.S. The Telegraph says, “Critics argue that drugs companies have profited by medicalizing a problem whose real causes may lie in psychological or relationship issues.”
