In an interview with fellow Oscar winner Brie Larson forĀ The Edit, the 79-year-old also said she had once lost a job because she refused her boss's sexual advances.
The star added she thought being a young actress now was "terrifying" because of female sexualisation.
"You have to get naked so much. There is even more emphasis on how you look."
Fonda said she "felt diminished" growing up because the men in her life were "victims of a [patriarchal] belief system".
