Which organ's posterior point is located at PSIS?

Understanding Chapman reflex points helps explain why the prostate’s posterior point is located at the PSIS. Chapman points are small, palpable locations on the body that correspond to visceral organs; posterior points sit on the back and align with the organ’s reflex pathways through the spine and pelvis. For pelvic organs, the prostate’s posterior reflex point is situated in the sacral–iliac region near the posterior superior iliac spine. That anatomical relationship makes PSIS the landmark for the prostate’s posterior point. Other organs have posterior points mapped to different locations along the spine or pelvis, so the PSIS area is specifically tied to the prostate in this system.
