Abstinence




Acts as a contraceptive by eliminating the
possibility of sperm entering the woman’s
vagina
Completely effective in preventing pregnancy
Is a means of avoiding STIs
Rhythm method of contraception includes
abstinence during the point in her menstrual
cycle when she is most fertile
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
8
Fertility Awareness


The understanding that a woman is fertile at
ovulation
Time of ovulation can be confirmed by

Basal body temperature (BBT)
 Cervical mucus method (known as the Billings
method)
 Symptothermal method
 Chemical predictor test
 Rhythm methods (also called the calendar
method)

9
Mechanical Barrier Methods



Chemicals or devices
Prevent transport of sperm to cervix or
implantation of fertilized ovum
Spermicides inserted at least 1 hour before
coitus

Usually ineffective if used alone; use with condom,
diaphragm, or cervical cap
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
10
Vaginal Spermicides





Immobilize and destroy sperm
Neutralize vaginal secretions
Viruses and some other pathogens are not
susceptible to spermicides
Cannot be relied on to protect against STIs
Examples: creams, foams, film, suppositories
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
11
Spermicides

Activate when exposed to body warmth in
vagina

Short-acting
 Inactive within an hour after insertion
 A single application provides protection against
one ejaculation
 Can be messy, leak


Low-cost and safe
Failure rate is 6%
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
12
Male Condom





Flexible sheath worn over erect penis
Inexpensive, accessible, effective means of
contraception
Reduces spread of STIs
Failure rate 3%; if used with spermicides,
failure rate 2% or less
Four basic features differ among condoms




Material: latex or polyurethane
Shape: reservoir at tip
Lubricant: wet jelly or dry powder
Spermicides
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
13
Male Condom (cont.)

Latex


Prolonged storage in hot, humid climates or
contact with vaginal antifungal creams, suntan oil,
or oil-based lubricants such as petroleum jelly, will
cause the latex to break down and the condom will
be ineffective for birth control
Polyurethane

Less constricting fit, more resistant to deterioration
 May enhance sensitivity
 Compatible with oil-based lubricants
 Protect against STIs
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
14
Female Condom

A thick lubricated polyurethane sheath, 7
inches long with flexible ring at each end







Inner ring serves as means of insertion
Covers cervix like diaphragm
Second ring remains outside vagina
Can insert up to 8 hours before intercourse
OTC and single use only
Do not use with male condom
Failure rate is 21%
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
15
Diaphragm

Latex or rubber cup surrounded by spring or
coil that fits snugly over cervix



Can put spermicidal cream or gel in dome and
around rim
Prevents passage of sperm into cervix
Requires fitting by health care provider

Size should be rechecked after each term birth or
if woman gains or loses 4.5 kg (10 lbs)
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
16
Diaphragm (cont.)






Holds spermicide in place against cervix for
the 6 hours it takes to destroy the sperm
Can be inserted up to 4 hours before
intercourse
Spermicide must be inserted into vagina each
time intercourse is repeated
Do not leave in place longer than 24 hours
Cannot be relied on to protect against STIs
Failure rate is 6%
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
17
Cervical Cap

Cup-shaped device, smaller than diaphragm




Once placed over cervix, remains in place by
suction
Not all women can be fitted for this
Can remain in place 24 to 48 hours
Fitting should be checked yearly, after
childbirth, and after vaginal or uterine surgery
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
18
Intrauterine Device (IUD)





Small, T-shaped, flexible device inserted by
health care provider
Provides continuous pregnancy prevention
Most often prescribed for women who have
had at least one term pregnancy
Not recommended for women with multiple
sexual partners
Does not protect against STIs

Hormonal Contraceptives
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
21
Oral Contraceptives (OCs)

Birth control pill




Prevents pregnancy by suppressing ovulation
through combined actions of synthetic estrogen
and progestin
Thickens cervical mucus
Alters decidua of uterus, preventing implantation
Failure rate 1% if taken as directed
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
22
“Minipill”


Contains only progestin
Works in same way as regular pill but is less
effective in suppressing ovulation
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
23
Side Effects of OCs

Can range from nausea to breakthrough
bleeding to thrombus formation




May be either estrogen- or progestin-related
Adolescents must have at least three
ovulatory cycles before starting OCs
After term delivery, OCs can be started about
4 weeks postpartum
OCs can decrease volume of breast milk, so
do not start until milk well-established

Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
30
Implantable Contraceptives






Can be inserted or removed in outpatient
clinic under local anesthesia
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
31
Injectable Contraceptives

Depo-medroxyprogesterone acetate (DMPA)
suspension (Depo-Provera)



Single injection every 3 months



Long-acting, injectable progestin
Alters cervical mucus so it is hostile to sperm
• Impairs ovulation and implantation
Contraceptive effect could last up to 1 year
Pregnancy test performed before first
injection
Side effects: menstrual spotting, headache,
weight gain; does not protect against STIs
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.

33
Least Effective
Methods of Contraception
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
34
Coitus Interruptus
(Withdrawal)





Man withdraws penis from vagina before
ejaculation
Prevents large quantity of sperm from being
deposited into vagina
May misjudge timing and withdraw too late
Also, fluid that escapes from penis before
ejaculation also contains sperm
NOT A RELIABLE METHOD OF BIRTH
CONTROL
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
35
Postcoital Douche




Sperm are known to appear in cervical mucus
within a few seconds after ejaculation
Sperm can reach site of fallopian tube within
a short time
Once sperm are in tube, pregnancy can result
and douching will not prevent this
NOT A RELIABLE METHOD OF BIRTH
CONTROL
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
36
Breastfeeding




Inhibits ovulation because prolactin alters
ovarian response to hormones and return of
menses
Frequency, intensity, and duration of
breastfeeding may maintain anovulatory
status for 4 to 6 months; then prolactin
decreases and ovulation returns
Pregnancy can occur before menses return
NOT A RELIABLE METHOD OF BIRTH
CONTROL

37
Permanent Contraception

Legal aspects

Informed consent
• Should include risks, benefits, alternatives, and a
statement that procedure is permanent and may be
irreversible

No absolute guarantee that the procedure will
prevent pregnancy in most procedures
 Some states require a 30-day waiting period

38
Male Sterilization

Minor surgical procedure






and occluded
Takes approximately 6 weeks and up to 36
ejaculations to clear remaining sperm
On follow-up visits, man may be asked to
submit semen samples to assess sperm
count
Can be reversed in some cases
Vasectomy has no effect on sexual
performance
Copyright © 2012, 2008 by Saunders, an imprint of Elsevier Inc.
39
Female Sterilization





performance
