Hey GnRnE, this is BK. Randy’s actually right I believe in that left or right determines which way it points, assuming this is a harder implant. I believe the reason is that your chest muscle and ribcage are slanted in opposite directions, so if the wrong side is put in, it’s like your boob has a lazy eye staring at some random kid when it’s cold outside. Actually, I doubt that would happen, but it would look very weird and unnatural. I don’t really know for sure if that’s the real reason, but if it’s a pre-formed implant then that would make sense.
