2. Figure 1
Nerve fibers in peritoneal endometriotic lesions treated with progestogens. (A) A peritoneal lesion from a treated patient stained for protein gene product 9.5 (PGP9.5). Black arrows denote nerve fibers stained for PGP9.5, and a yellow arrow denotes an endometriotic gland. (B) A peritoneal lesion stained for neurofilament (NF). Arrow denotes myelinated A-delta nerve fibers stained for NF. (C) A peritoneal lesion stained for TH. Arrow denotes adrenergic nerve fibers stained for tyrosine hydroxylase (TH). (D) A peritoneal lesion stained for vesicular acetylcholine transporter (VAChT). Arrows denote cholinergic nerve fibers stained for VAChT. (E) A peritoneal lesion stained for vasoactive intestinal polypeptide (VIP). Arrow denotes sensory C nerve fibers stained for VIP. (F) A peritoneal lesion stained for neuropeptide Y (NPY). Arrow denotes sensory C nerve fibers stained for NPY. (G) A peritoneal lesion stained for CGRP. Arrow denotes a very small number of sensory C nerve fibers stained for calcitonin gene related peptide (CGRP). (H) A peritoneal lesion stained for substance P (SP). There was no positive SP staining in this progestogen-treated woman. (A: magnification ×200. B–H: magnification ×200.)

Peritoneal endometriotic lesions from women who were receiving progestogens. (A) A peritoneal lesion strongly stained for nerve growth factor (NGF) throughout the stroma (magnification ×100). (B) A peritoneal lesion strongly stained for nerve growth factor receptor p75 (NGFRp75) throughout the stroma (magnification ×200).
