Predisposition Gyno?

i'm about to do my first cycle in a few weeks and was wondering how you would you know if you have a predisposition to gyno? checked educational threads before hand and couldn't find anything about the 'predisposition' aspect. Does it hav't to do with body type for the predisposition? myself, naturally an ectomorf with a very fast metabolism and always had very low body-fat (under 10%). would that mean i wouldn't have a predispostion to gyno? or is it one of those things i just gotta try to find out? :yellowcon
