What is considered to be the optimal body fat percentage in a female athlete?

Let me explain: The ideal weight and fat-lean ratio varies considerably for men and women and by age, but the minimum percent of body fat considered safe for good health is 5 percent for males and 12% for females. The average adult body fat is closer to 15 to 18% for men and 22 to 25% for women.

Athletes: Female athletes usually have 14 to 20% body fat. Male athletes usually 6 to 13% body fat. The numbers are considerably lower for body builders.
