1Where is Huiyin?

Our 3D measurement · Our 3D model's skin has no anus or scrotum, so the centre of the perineum (perineal body) was taken on the perineal skin below the line joining the lowest points of the two ischial tuberosities. It lies 13.2 mm in front of the estimated anus (lower end of the superior rectal artery) — still to be verified.

2How do I find it on my body?

Lie on your side or take the knee-chest position.
Find the midpoint between the anus and the external genitals.

📖 Words explained

pubococcygeus: Part of the muscle that forms the pelvic floor (levator ani). It runs from behind the pubic bone toward the coccyx and supports the pelvic organs from below.
hip bone: The large, wide bone on each side of the pelvis, formed when the ilium, ischium and pubis grow together. The ridge you feel at belt level (iliac crest) is its top edge.
