Pelvic Inflammatory Disease

Pelvic inflammatory disease (PID) is a general term that refers to infection and inflammation of the upper genital tract in women. It can affect the uterus, fallopian tubes, ovaries, and other organs related to reproduction. The scarring that results on these organs can lead to infertility, tubal (also known as “ectopic”) pregnancy, chronic pelvic pain, abscesses (sores), and other serious problems. PID is the most common preventable cause of infertility in the United States. Scientists supported by NIAID are conducting studies to improve understanding of how to prevent infertility and other complications of PID.
