Unintended Pregnancies
Unintended pregnancies with various contraceptive methods
Numbers given are pregnancies for every 1000 women during first year of use
*This perfect use failure rate corresponds to the Nova-T 200. The typical failure rate of the Nova-T 200 is likely slightly superior.

Oralcontraceptives
sexualityandu.ca
What are they?
• Prescription tablets taken once a day
• There are two main types:
1. Combination pill which contains two female hormones similar to
the body’s own estrogen and progesterone
2. Progestin-only pill (or mini-pill) which does not contain estrogen
• Available under a variety of brand names with various strengths and
formulations
How do they work?
• Stop the release of a mature egg
• Thicken the cervical mucus making it difficult for sperm to get to the egg
• Change the lining of the uterus making implantation difficult
Failure rate: 80 per 1000 women per year

to ensure that the IUS is still in place

Femalesterilization
sexualityandu.ca
Sites of
Sterilization
Tubal occlusion “Having your tubes tied”
What is it?
• A surgical procedure to close or block the fallopian tubes
• Techniques include:
• Laparoscopy – special instruments are inserted through two tiny
incisions (less than 1 cm long) in the abdomen
• Mini-laparotomy – also requires a small cut in the abdomen
• Hysteroscopy – use of a thin telescope inserted into the uterus
• Fallopian tubes may be blocked by using one of the following:
• A clip or a ring
• Cautery (an electric current)
• Removing a small piece of each tube
• Hysteroscopy for the insertion of tubal plugs (Essure)
How does it work?
• The fallopian tube is blocked and therefore the
sperm and egg cannot meet
Failure rate: 5 per 1000 women per year
Essure
Ligation
Clips
Cauterization
Femalesterilization
sexualityandu.ca
What are the advantages?
1. No daily contraceptive routine required; nothing to remember

vagina and preventing the exchange of body fluids
• Sperm is trapped in the condom, which is thrown away
after intercourse
• A new condom should be used for each repeated
act of intercourse
Failure rate: 210 per 1000 women per year

Femalebarriermethods
Diaphragm and Cervical Cap
Cervical Cap
Diaphragm
What are they?
• Intravaginal barrier methods that are used together
with a spermicide
• The diaphragm is a latex dome with a flexible steel
ring around its edge (a non-latex diaphragm is also
available)
• The cervical cap is thimble-shaped silicone cap
• Positioned into the vagina (diaphragm) or over the
cervix (cervical cap) before intercourse
• Must be left in the vagina for 6–8 hours after intercourse
How do they work?
• A pelvic examination by a qualified health care
professional is required for fitting diaphragms and
cervical caps
• Inserted into the vagina and fit over the cervix
• When positioned properly, they block the entry to
the uterus so sperm cannot enter and
fertilize the egg
• Spermicide should be reapplied for
each repeated act of intercourse
Failure rate: 160-320 per
1000 women per year
sexualityandu.ca
Femalebarriermethods

contact and the exchange of genital fluids, so the
sperm does not enter the uterus and fertilize
the egg

of intercourse
Failure rate: 150 per 1000 women per year

Malesterilization

is made in the scrotum
• Vas deferens are closed by:
Vas
Urethra
deferens
• Electric current (cauterization)
• A mechanical method, such as a clip
• Removal of a small segment of each tube
• Another form of contraception is required
until a semen analysis shows no sperm

Dental dams and gloves
A dental dam is a small piece of latex similar to the material used for latex
condoms.
• It can be used during oral sex. The dental dam is stretched across a
woman’s vagina to prevent the exchange of bodily fluids.
• It can also be used in other activities where a barrier is desired.
• Latex surgical gloves can also be used in activities where a barrier is
desired.
General tips
• When using latex dental dams, gloves, or condoms, apply only waterbased lubricants. They are available at drugstores.
• Use new dental dams, gloves, or condoms for each partner.
• Do not re-use latex barriers or turn them over and use the other side.
STIprevention
sexualityandu.ca
Cutting a condom to make a dental dam
1
• When a dental dam is not available, a latex condom can be cut to create
a latex barrier.
1. Unroll a new condom.
2. Using scissors, cut off both ends of the condom, removing the
closed tip and the round loop at the base.
3. Cut the condom lengthwise so that it opens up into a rectangle.
2
• If you are going to use the barrier for oral sex, you may wish to select a
condom without spermicide or lubrication. A flavoured condom may be
a good choice.
