IUD

  • It prevents the embryo from implanting in the uterus
  • by changing the lining of the uterus
  • The chemical reaction caused by the IUD in the uterus also affects sperms

  • Increases chances of ectopic pregnancy (this leads to a miscarriages which can be fatal)
  • Some models have to be replaced by a medical professional every year
  • Can lead to increased menstrual bleeding and cramps

Side effects
