Your post sounds a like an effort-troll, OP. However, if you are actually considering getting sterilized, answer me this: what kind of a reactionary would you be to voluntarily commit to having so much less skin in the game, forever*? More pragmatically, have you had any DNA tests done? Have you talked to actual MD doctors? Because of the absence of this information, the hemisphere explanation and other tells you come off as trolling. Nice Land ref, though.
