5-10 years
how long can the IUS last
3-8 years
how long can the contraceptive implant last
3 years

COCP - MOA
main MOA: inhibiting ovulation (negative feedback on FSH and LH)
progestogen in the COCP: thickens cervical mucus + thins endometrial lining
Oestrogen and progesterone have a negative feedback effect on the hypothalamus and anterior pituitary, suppressing the release of GnRH, LH and FSH. Without the effects of LH and FSH, ovulation does not occur. Pregnancy cannot happen without ovulation.
how long does it take for fertility to return to normal once you stop taking COCP
a month
