Factors thought to be protective against PID include:

  • pregnancy - blocks tubes of the upper genital tract
  • sterilisation
  • combined oral contraceptive pill - increases vaginal secretion of mucus so helping to protect against infection; not protective against chlamydial infection
  • barrier contraception - condom, diaphragm; protect against upper genital tract infection
