Birth Control, Pregnancy and Childbirth
Week # 8
- Fertility: is successful reproduction, conception
- The number of women pregnant between the ages of 15 and 19
Canada = 14/100 are pregnant
USA = 42/1000
- Factors that actually lead to ignoring contraception (ability to protect yourselves)
- Contraception 2 types
7 Types of Protection
- Condom: collects sperm from male; protects against TD for both M/F, if used properly 98%
effective; you need a tip at the end, if not it could cause pressure to break the condom; if it is not
put on correctly or if its damaged the effectiveness goes down to 95%
- Pill: increasing estrogen and progesterone levels, tricking the body that the women are already
pregnant (contraception pill)
- Micronor: used on woman who get a lot of side effects from using the other pill, it’s a progesterone
only pill, dos not increase levels of estrogen (contraception pill)
- Spermicide: destroying sperms in the vagina tract so it can’t go up the fallopian tubes; not as
effective; should be put in 20 minutes before intercourse
- Nuva Ring: inserted and placed near the opening of the cervix; releases its self-estrogen and
progesterone; works 3 weeks then needs replacement
- Synthetic Drug: lasts 3 months long (effective)
- Estrogen/Progesterone Pack: works similar to the contraceptive pills
8 Reversible Techniques
- Diaphragm: inserted by the user; can be put in with a spermicide; prior to sexual intercourse; over
the counter (no regulations with the medical society), if in for long time can increase bacteria within
the vaginal wall. Can enter toxic shock syndrome,
- Cervical Cap: fitted by a physician, through them only, stopping sperm from entering into the
- Sponge: inserted itself
- Female Condom/Dental Dam: works similar to the condom put in there.
- Male Pill: decreases sperm count, not a perfected science but sperm count stays low. Be aware of
pill called “Gossipol” some effectives, and some side effect but are not sure how long these side
effects are.
- IUD: Inserted into the uterus, oldest contraceptive techniques. Essentially prevent fertilization b/c
they act as a foreign object
- Withdrawal: avoiding ejaculation during intercourse.
- Coitus Interrupts: goes against when men saying once they start they can’t stop (myth)

- This being about women being more aware of their bodies
1. Calendar Method: regulating the length of menstrual cycle, year leading up before starting, some
women are regular some are not. There are many factors that influence.
Need to know longest menstrual period you have had
Need to know shortest menstrual period you’ve had
28 days not that regular
Point where you can have unsafe sex in cycle is taking shortest cycle minus 13 days
FSH & LH are increased during the proliferative phase
2. Cervical Mucus: females secrete fluid. If gelatinous, or increase mucus is indicative of ovulation
Women do examine their mucus and bodies, but not always accurate
3. Temperature: when ovulating there is an increase in core temperature, 8 degree increase
- There should communication between both partners about contraception
3 Types of Permanent Contraception
1) Tubal Ligation: takes place in the fallopian tubes, cutting off any opportunity for sperm to go up
to ovary. Cauterizing, cut (fallopian tubes can reattach), tie the cut ends, so if they grow
together nothing will happen. Or band the ends, can be removed.
2) Hysterectomy: removing the uterus, can take place through a c section or vaginal.
3) Vasectomy: small incision of the scrotum, cut and cauterize the vas deferens. Now they have
Managing Your Fertility
- Human error reason why most people get prego
- Male condom not using it right = technical difficulty 2% getting prego,
- Female condom not used right = bad aim, 5% chance of getting prego
- Withdrawal not doing it right = too slow 27%
- All of these are due to human error
Abortion (Elective Abortion
- Pro Life (anti-abortion) vs. pro choice (abortion okay/women has a choice)
Abortion is legal in Canada
Dr. Henry Morgentaler (1969) opened a clinic for abortion
*14 per 1000 women will have an abortion upon conception
1/3 live births of abortion
Higest age group for abortions are 20 to 24 years old (27.7/1000 women)
* Yukon 44/1000 (most abortions), least amount of abortions PEI 8/1000
Methods of Abortions
- (1st 2 happen during the first trimester)
- (3rd month is a fetus)
1. Vacuum Aspiration 1st trimester, risk is low, 8/100000 deaths
2. Dilation & Evacuation (D&E) D& Curetage (scraping uterine linin from the endometrial lining)
3. Hysterectomy surgical removal of the fetus
4. Induced Abortion injection of saline, or *prostaglandin which will terminate the fetus, gives birth
to a dead fetus.
