I don’t mean to be a nit picking nerd, but are you guys sure it’s the “septum” that’s causing the trouble. As I look at the linked diagram (page to the bottom for the x-c view), I see that the septum consists entirely of circumferential fibers. How can something that consists solely of circumferential fibers be so resistant to longitudinal stress?
I wonder whether it’s not the septum, but the dorsal thickening of the tunica above the septum that’s the culprit. The dorsal thickening (11 to 1 o’clock positions) is the thickest part of the tunica. The tunica is almost twice as thick at the 11 o’clock position as it is at the 9 o’clock position.
This difference may be significant since it means that stress should be concentrated on the top (dorsal) surface of the penis, not on some internal structure between the CCs.
