CAREFULLY pick off all the male parts and you will have ZERO seeds. Tweezers work well. If you break one of the sacs, though, the pollen will burst out and pollinate the whole plant, so be CAREFUL... Water will kill the male pollen, so you can spray them with some water before you pick them (Try not to water the female buds too much especially later in flowering, as they can gather mold).

If you let if grow, it will definitely pollinate itself and you will get next to no bud. So, better to try and pick those things off while you still can.
