DEAR DOCTOR K: I have pelvic inflammatory disease, and I'm worried this could affect my fertility.
DEAR READER: You're right to be concerned. Pelvic inflammatory disease (PID) is the most common preventable cause of infertility in the United States. The more often a woman gets PID, the greater her risk of becoming infertile. Most cases of PID develop from sexually transmitted diseases (STDs), usually gonorrhea or chlamydia.
