Prevention of ovulation (acts on hypothalamo-pituitary-ovarian axis to suppress LH and FSH) (Also changes to cervical mucous, endometrium and tubal motility)

How do POPs work?

-increase volume and viscosity of cervical mucous -Suppress ovulation -Endometrial changes -Reduction in cilia activity -slow passage of ovum

How does copper IUD work? When does it start working?

Effective immediately following insertion TOXIC effect of copper on ovum/sperm Changes to cervical mucous (For emergency contraception) - endometrial inflammatory reaction has anti-implantation effect
