The presence of ≥2 major criteria and ≥1 minor criterion was sufficient for PID. The presence of 1 major criterion and ≥1 minor criterion was suggestive of PID. The presence of ≥1 minor criterion was sufficient for lower reproductive tract infection only. There was 1 animal with PID in the non-LNG group, 3 with criteria suggestive of PID, and 3 with infections in the lower reproductive tract only. There were 2 animals in the LNG-IUS group with PID, 3 with criteria suggestive of PID, and 1 with infection in the lower reproductive tract only.
