Comparison of total nerve fiber density and sympathetic nerve fiber density in deep infiltrating endometriotic specimens of uterosacral ligament and healthy uterosacral ligament.

(A) Total nerve fibers were positively stained by Anti-PGP 9.5 antibody. Comparison of the total nerve fiber density (NFD, NF/mm2) of endometriosis-associated nerve of deep infiltrating endometriosis of uterosacral ligament (EAN-USL-EM), NFD of para-endometriotic nerve of deep infiltrating endometriosis of uterosacral ligament (PEN-USL-EM) and NFD of nerve of uterosacral ligament of control (N-USL-C). (B) Sympathetic nerve fibers were positively stained by Anti-TH antibody. Comparison of endometriosis-associated sympathetic NFD of USL-EM (ESAN-USL-EM), para-endometriotic sympathetic NFD of USL-EM (PESN-USL-EM) and sympathetic NFD of uterosacral ligament of control (SN-USL-C). *P<0.05.
