I heard the males have more hairs and a certian "ball sack" ?

 

[Hightide805]

ya males have balls
females have flowers aka bud

so no males unless you want balls (seeds) ...this site has a bunch of pictures of the difference, and you can't tell untill flower (12/12) cycle

Same as Human reproductive acts to create little babies. A Male pollen has to dust itself to a female in order to achieve seeds. If this does not happen then the Female reamains Seedless AKA Sin Similla or "Without Seeds" Con Similla would be "Seeded"
Getting into Hermies and stuff is another story all in it self.
Males do not produce seeds themselves, just Pollen.
