Abstract

OBJECTIVE: To determine the effects of hysterosalpingography (HSG) contrast media (CM) and chromotubation dye on peritoneal lymphocyte proliferation and macrophage phagocytosis in vitro. DESIGN: Peritoneal fluid (PF) lymphocytes and macrophages were isolated from 40 subfertile women undergoing diagnostic laparoscopy and 12 fertile women having laparoscopic tubal ligation. Dilutions of renografin, ethiodol, methylene blue, and indigo carmine were added to peritoneal lymphocyte and macrophage cultures. Tissue culture media alone served as control. Lymphocyte proliferation was assessed by hemocytometer counts and 3H-thymidine incorporation. Macrophage function was determined by phagocytosis of fluorescent microspheres. RESULTS: Peritoneal lymphocyte proliferation and macrophage phagocytosis were significantly inhibited by renografin, ethiodol, methylene blue, and indigo carmine in a dose-dependent manner. CONCLUSION: Inhibition of PF immune cell function by HSG CM and chromotubation dye may provide a potential mechanism for fertility enhancement after these diagnostic procedures.
