Mechanism of IUCD includes all except:
MECHANISM OF ACTION IUDs Intrauterine device: Foreign body reaction in uterus Cellular and biochemical changes in Endometrium and uterine fluids. Impaired bility of gamete. Reduced chances of feilization. Copper ions (2nd generation) Alter biochemical composition of cervical mucus. Affect sperm motility/Capacitation / survival. Hormones (3rd generation) in IUD Increase cervical mucus viscosity, preventing sperm from entering cervix. Sustain unorable Endometrium for implantation by maintaining high level of progesterone.
Increase cervical mucus
Local foreign body like reaction
Decrease diameter of fallopian tube
Make Endometrium unourable for implantation
