Contraception Flashcards
OCP: Mechanism of action
Influence of estrogen (ethinyl estradiol):
Inhibits the midcycle surge of gonadotropin FSH which prevents ovulation
Influences progestin to suppress LH suppressing ovulation and thickening the cervical mucous to inhibit sperm migration

Known CVD, cardiomyopathy, BP 160/100 or greater, complicated valvular heart disease

the only proven antimicrobial shown to decrease the efficacy of OCs
Rifampicin
Progestin Only Methods: Mechanism of Action
Inhibition of gonadotropin secretion
With resultant inhibition of follicular maturation and ovulation
Thickens cervical mucus
Creates thin, atrophic endometrium
Ovum transport may be slowed by reduced ciliary action in tubes
Progestin Only Methods BBW
limit use to 2 years if possible, although no proven increased fracture risk.
