- Failure Rate Parous (Given birth before):
- Perfect: 20%
- Typical: 24%
- Moisten with water; lasts 12 to 24 hours; removed 6 to 8 hours after last ejaculation
- No prescription needed, one size fits all, already contains spermicide, multiple intercourse acts within the effective period
- High failure rates
18

20
Q
Spermicides
A
- Failure Rate:
- Perfect: 18%
- Typical 28%
- Spermicide should be paired with barrier methods in order to be more effective; regardless of how long the spermicide is effective, it is only effective for one act of intercourse
- Vaginal contraceptive film: inserted into the vagina at least 15 minutes, but no more than an hour prior
- Bioadhesive jelly: inserted with an applicator, effective immediately and for up to 24 hours
- Foam: Inserted with an applicator; effective immediately and for up to 1 hour
- Suppositories: Inserted 10 to 15 minutes prior to intercourse; effective for 1 hour
- Jellies or creams: Primarily for use with a diaphragm or cervical cap; effective for 6 to 8 hours if used with these devices or 1 hour if used alone
- Can function as a lubricant, no prescription needed, can reduce risk of PID
- Can contain irritants to the skin, yucky taste, takes a little bit to work
21
Q
Internal condoms
A
- Creates a physical barrier to trap sperm
- Failure Rate:
- Perfect: 5%
- Typical: 21%
- Inserted into vagina up to 8 hours before intercourse, with flexible ring end at cervix, outer portion covers the vulva
- Protects against STIs, no prescription needed, can be used for anal if you remove the rink
- Bulky, crinkly, suction noises, expensive
22
Q
External condom
A
- Creates a physical barrier to trap sperm
- Failure Rate:
- Perfect: 2%
- Typical: 18%
- Rolled onto penis, must be used with a water-based lubricant to not break the condom
- No prescription needed, help protect against STIs, can be found for free
- Effectiveness decreases if not stored correctly or expired, good ones can be expensive
23
Surgical Methods
- Female sterilization (tubal ligation)
- Male sterilization (vasectomy)
24
Female Sterilization
Tubal Ligation
- Prevents the egg and sperm from ever meeting because fallopian tubes are severed
- 99% effective
- Surgeons seals the fallopian tubes through burning, clopping, cutting or tying
- Does not protect against STIs, requires surgery
25
Male Sterilization
Vasectomy
- Prevents sperm from entering ejaculate because vas deferens is severed
- Failure Rate: 0.05%
- Sperm will still be in the ejaculate for 10 to 30 ejaculations
- Removes 1.5cm segment from each end of the vas deferens, and the ends are sealed with a suture, cauterization, or clips
- Simple procedure, reversible
- Does not protect against STIs, may have some pain for a little bit after the procedure, semen analysis is needed after to ensure effectiveness
26
Amenorrhea
- Absence of period
27
Chronic Pelvic Pain (CPP)
- Chronic or recurrent pelvic pain that apparently has a gynaecological origin but for which no definitive cause can be found
28
Vaginitis
- Inflammation of the vagina
- Usually due to infection
- Can result in discharge, irritation, and pain in vagina and vulva
29
Toxic Shock Syndrome
- Serious but uncommon bacterial infection, originally associated with tampon use but now known to have an association with some contraceptive barrier methods
30
31
Natural Methods
- Do not protect against STIs
- Intercourse must be avoided during the ovulation phrase
32
Fertility Awareness Methods
- Rely on a detailed understanding of female physiology and menstrual cycle
- Failure Rate of 24%
- Can be really complicated to understand/remember and may also be messed up by a lot of factors
33
The sympto-thermal approach
- Used to chart basal body temp, cervical position, and cervical mucus to gain insight into when one is fertile and therefore likely to get pregnant
- Rise of 0.2 degree following ovulation, and the fertile time last three days following this temp rise
- Perfect use is 91 to 99% effective and typical use if 80% effective
34
Rhythm Method
- Calendar based method of family planning that estimates the start and end of the fertile time based on past cycle lengths and involves abstaining from intercourse during the fertile time
- Low failure rate, but shouldn't be the primary method because there are too many things that are unpredictable
35
Lactational Amenorrhea
- 98% effective
- Hormonal suppression of ovulation caused my breastfeeding
- Must be exclusively breastfeeding pretty much for it to work
36
The Withdrawal Method
- One must be able to recognize when ejaculation is imminent and have the self control to withdrawal
- Effectiveness:
- Perfect: 96%
- Typical: 81%
- Pregnancy can still occur from pre-ejaculate
37
Abstinence
- Refraining from some or all aspects of sexual activity
- Can be 100% effective if they actually follow it
- We should teach this as an option to kids, not the only option because then they'll engage in risky sex practices
38
Birth Control around the World
- Mostly used by women
- Most common contraceptive methods in the world are female sterilization, IUD, OC pills, and condoms
39
Birth control in Canada
- Most used: condoms, OC pills, withdrawal method
- Don't have much access in the country as others
- IUD is on the rise
40
Why use birth control
- People don't have money
- We don't want teen pregnancy
- We don't want an overpopulation issue
41
Not getting birth control
- 28% of women have not asked their doctors about birth control
- Some may not feel comfortable or have opportunities to ask
42
Why do people take sexual risks
- Personality, situational, and relationship factors may influence an individual's decision to engage in sexual risk taking
43
Information-Motivation-Behavioural Skills (IMB) model
- Social psychology model that identifies three major components
- Information,
- Motivation, and
- Behavioural skills
- These may directly or indirectly affect sexual health behaviours
- Ex: Contraceptive needs to be available and understood (information), they need the motivation to use the contraception (motivation), need to be confident in getting and using the contraception (behaviour skills)
- This can be achieved through sex ed
44
Talking to your partner about contraception
- Doesn't need to be a long conversation
- Just tell them if you're on anything or if they should get a condom type vibe
- Longer term relationships may want longer term solutions
- Both partners should have equal part in contraception
45
Emergency contraception (EC)
- Any contraceptive method used after intercourse and before the time that the egg can implant in the uterine lining
- Not the same as an abortion, and it does not have an effect on established pregnancies
- Not recommended as a regular method of birth control, ut rather just a backup
- Two main methods: Hormonal and the IUD
46
The Emergency Contraceptive Pill
- Plan B: Levonorgestrel and progestogen
- Yuzpe: Levonorgestreal, ethinyl estradiol, and estrogen
- Plan B is more effective and has fewer side effects
- Available without prescription since 2005
- Should be taken within 72 hours
- Reduce risk of pregnancy by 75 to 89%
47
Post-coital IUD Insertion
- Post coital insertion of an IUD
- Effectiveness approaches 100%
- Needs to be inserted within seven days
- Requires a doctors appointment and prescription
- Similar side effects to the ones of getting a normal IUD
48
Therapeutic abortion
- Abortion when the birthing person's life is at risk
- Preg is likely to cause severe physical or mental health consequences in the parents, or the fetus has severe problems
49
Elective Abortion
- Performed for other reasons than maternal or fetal health
50
History of abortion in Canada
- 1869: Abortion was made illegal in Canada leading to potential life in prison
- Dr Henry Morgentaler was like nah, later went to the supreme court and won in 1988
- The Canadian Abortion Rights Action League was the first national abortion rights group
51
Medical Nonsurgical Abortions
- Performed up to seven weeks following the last menstrual period, but can be done up to the tenth week of gestation
- Doctor injects methotrexate into the hip muscle to stop the growth of the fetus
- Five to seven days later the woman takes misoprostol as a pill or as a suppository to cause the uterus to contract and the contents of the uterus are usually expelled with 24 hours
Or
- Mifepristone which blocks progesterone, which prepares the lining of the uterus for an egg. Without progesterone the preg cannot proceed
- Then they take misoprostol
- About 94 to 98% effective
52
Surgical abortions
- Manual vacuum aspiration
- Vacuum suction curettage
- Dilation and Evacuation
53
Manual Vacuum aspiration
- During the first seven weeks of preg
- Flexible plastic tube is inserted into the cervix and a syringe attached to the tube removes the contents of the uterus by creating suction
54
Vacuum suction curettage
- 6th to 14th week of gestation in hospital
- Under general or local anaesthetic
- Cervix gets dilated
- Tube is inserted and the contents of the uterus are suctioned out, then a curette is used to scrape the lining to ensure everything is removed
- Less than a 1% failure rate
55
Dilation and Evacuation
- 13th to 16th weeks
- Similar to vacuum suction curettage but more complicated because of the size of the fetus
- Must be done under general anaesthetic
- Beyond the 16th week the fetus must be removed with forceps
56
57
Second and third trimester abortions
- Occur after the 20th week of gestation
- Inject a substance to stop the fetal heart and remove the fetus with forceps
- May induce labour to deliver or get a C-section as a last resort
58
Psychological effects of abortion
- Severe negative psych rections are rare, then tend to be mild with slight regret, sadness, or guilt
- A lot of people have relief and happiness
- Majority don't have long term issues
59
Adoption
- Putting kids up for adoption is pretty rare (estimate of around hundreds)
- Majority of unplanned preg end either in abortion or in parenting
- There are still lots of kids to adopt, just not babies
