44-45: Contraception Flashcards
Hormonal Contraception forms efficacy
- implant
- IUD
- shot
4-6: pill, ring, patch
Hormones in contraceptives
-estrogen
-progestin
Mech of estrogen as contraceptive
-suppress FSH production = prevent dominant follicle = no ovulation
-inc sex-hormone binding globulin = inc binding of free androgens (dec acne)
Mech of progestin in contraceptives
-prevent LH surge = no ovulation (not most effective mech)
-thicken mucus = inhibit sperm
-change motility of tubes = inhibit sperm/ova transport
-atrophy of endometrium = no implantation
Common estrogens
-ethinyl estradiol
-estradiol valerate
-estetrol
-mestranol
Common progestins
-northindrone (acetate)
-norgestimate

-endometriosis
-dysmenorrhea
Potential health benefits of hormonal contraceptives
-dec risk of endometrial and ovarian cancer
-dec risk of pms headaches
-improvement in perimenopausal symptoms
Contraceptive considerations
