what are examples of permanent types of contraception (2)
- vasectomy
- tubal ligation
what are considered the most (1-2 pregnancies/100 people)effective methods of contraception (5)
- progestin only IUS
- progestin implant (0.5/1000) (Nexplanon)
- vasectomy
- tubal ligation/occlusion
- non-hormonal IUD - copper

- combined estrogen & progestin oral pills – COC
- patch
- vaginal ring
- lactational amenorrhea
- progestin only injection
- progestin only mini - pill
what are the least effective (>13 pregnancies/100 people) methods of contraception (3)
- withdrawal
- fertility awareness
- barriers: condoms
there are more contraindications to estrogen or progesterone?? what does this mean?
- more contraindications to estrogen than progesterone = some people may need progesterone only pill
how do hormonal pills vary
- some have steady state of hormones
- or ones which fluctuate week by week
what type of IUDs are extremely effective?
- hormonal IUDs
what is nexplanon
- progesterone-only implant injected into inner arm
describe the release of hormones via nexplanon, how long does it stay in?
- releases hormones slowly
- stays in for 3 years
how often and where is a progestin injection given?
- given in muscle once every 12-15 weeks
which is more effective: progestin only pill or combined
- combined
what is imp to note with progestin only pills to prevent decreased effectiveness
- taken at exact same time every day
describe reversal of tubal ligation
- very difficult to reverse
describe the presence of hormones in a copper IUD
- contains no hormones
what is lactational amenorrhea
- protection provided by chest feeding
with lactational amenorrhea, what should still be used?
- condom
ovulation may still occur w lactational amenorrhea if..
- if breastfeeding is infrequent (less than q4h in day or 6 hrs at night)
what should be assessed r/t contraception (10)
- reproductive health history (include STIs)
- general & current medical history
- meds
- current knowledge on reproduction, sexual health, contraception, and STIs
- ability to access (afford)
- efficacy
- adherence
- protection from STIs
- comfort
- contraindications
define efficacy r/t contraception
- how important it is that you do not become pregnancy
what should be recommended if the pt absolutely does not want to become pregnant?
- high effectiveness methods of contraceptions
describe adherence r/t contraceptions
- how well someone will be able to stick to the contraceptive method
ex. if cant remember to take pill every day, look at other options
what is the only thing that protects against STIs
- condoms
due to the protection condoms provide against STIs, when should condoms for sure be used? (2)
- if you don’t know someone’s STI status
- or are not monogamous
what should be considered r/t comfort w contraception
- invasive vs noninvasive
ex. some dont want IUDs
describe the need for parent consent for medical treatment in canada
- in Canada, an adolescent does not require parental consent for medical treatment including contraception
what is included in hormonal contraception (6)
- combined oral contraceptive (COC)
- progestin-only pill (POP)
- injectable contraception
- vaginal ring
- contraceptive patch
- intrauterine contraception (IUS/IUD/IUC)
what are side effects to monitor for with hormonal contraception
ACHES
what does ACHES stand for
Abdominal pain
Chest pain/dyspnea
Headache (severe)
Eye problems
Swelling & leg pain
why is it important to assess for abdominal pain w hormonal contraception
- increased risk for liver or gallbladder problems
why is it important to monitor the “CHES” of ACHES with hormonal contraception
- related to clotting or strokes
what is the MOA of COC (4)
- suppresses ovulation
- endometrial changes to reduce chance of implantation (decreases proliferation)
- thickens cervical mucus
- impairs motility of fallopian tubes
what are benefits of COC (4)
- shorter menses
- regular cycle
- reversible
- reduces risk of endometrial & ovarian cancer
what are risks of COC (2)
- VTE
- side effects
what are contraindications of COC (10)
- smoking and age >35
- HTN
- VTE
- heart disease
- CVA
- breast cancer
- liver disease
- migraines w aura
- diabetes w complications
- AUB
what is a risk associated w COC
- clotting
define: aura
- visual disturbances prior to migraine
ex. lights, spots
with diabetes, what should be considered with COC contraception
- weigh risk of pregnancy (very risky) against risk of taking pill
what is AUB? what should be done w this prior to prescribing a hormonal pill to regulate
- abnormal uterine bleeding
- should investigate why this is happening
what is the MOA of POP (4)
- suppresses ovulation
- endometrial changes to reduce chance of implantation (decreases proliferation)
- thickens cervical mucus
- impairs the motility of fallopian tubes
what are benefits of POP (4)
- can be used when estrogen is contraindicated
- shorter menses
- regular cycle
- reversible
what are risks w POP
- side effects
what are contraindications to POP (3)
- breast cancer
- AUB
- liver disease
what is an imp consideration w POP
- take at same time every day
what is imp to note w suppressing of ovulation w COC vs POP
- POP not as consistent in suppressing ovulation
is there any STI protection with oral contraceptive pills?
- no
intrauterine contraception is placed where? by who?
- in the uterus by a provider
what options are available w intrauterine contraception (2)
- hormonal option
- non hormonal options (copper)
describe the effectiveness and reversibility of intrauterine contraception
- highly effective
- reseversible
in a hormonal IUD, what hormones are present
