Physician: Heart disease generally affects men at an earlier age than it does women, who tend to experience heart disease after menopause  Both sexes have the hormones estrogen and testosterone, but when they are relatively young, men have ten times as much testosterone as women, and women abruptly lose estrogen after menopause
We can conclude, then, that testosterone tends to promote, and estrogen tends to inhibit, heart disease
Hormone levels do not vary from person to person, especially among those of the same age and gender.
