
The practice of avoiding sexual
intercourse
Safe
 Free
 Available to all
 100% effective in preventing pregnancy
& STIs
 Can be initiated at any time
 Encourages communication between
partners


Both participants must practice selfcontrol

Teach alternative methods of obtaining
sexual pleasure

Provide positive feedback to clients who
desire and maintain abstinence
AKA withdrawal
 Male partner
withdraws penis prior
to ejaculation
 Effectiveness
depends on man’s
ability to withdraw
prior to ejaculation


Can be practiced at any time during the
menstrual cycle

Free
One of the least reliable contraceptive
methods
 Only 80% effective
 Does not protect from STIs
 Some pre-ejaculatory fluid, which may
contain sperm, may escape from the
penis during the excitement phase prior
to ejaculation
 At the peak of sexual excitement,
exercising self-control may be difficult

Before engaging in sexual intercourse,
the male should urinate and wipe off the
tip of the penis to decrease the potential
of introducing sperm into the vagina
 Conception may occur if preejaculatory fluid containing sperm enters
the vagina
 A spermicide or post-coital
contraceptive may be needed if the
female partner is exposed to sperm


Calendar based
methods

Symptoms based

methods
Free
 Safe
 Acceptable to couples whose religious
beliefs prohibit other methods, such as
Roman Catholics
 Increases awareness of the woman’s
body
 Encourages couple communication
 Can be used to prevent or plan a
pregnancy


education


Based on assumption that ovulation
occurs 14 days prior to the next menses,
sperm are viable for 5 days, and the
ovum is capable of being fertilized for 24
hours

91% effective if used perfectly
Based on number of days in each cycle,
counting from first day of menses
 Beginning of fertile period is estimated by
subtracting 18 days from length of
shortest cycle in last 6 months
 End of fertile period is determined by
subtracting 11 days from length of
longest cycle


Shortest cycle 24 days
24-18 = 6th day

Longest cycle 30 days
30 -11 = 19th day
•
To avoid conception the couple would
abstain during the fertile period days 619

You are educating a client on the
contraceptive calendar rhythm method.
When you ask her how long her cycles
have been for the last 6 months, she
explains that her cycle is consistently 28
days. What days should you tell her to
abstain from sexual intercourse???

Shortest cycle 28 days
28 -18 = 10th day

Longest cycle 28 days
28 – 11 = 17th day
To avoid pregnancy the couple abstains
from day 10-17.

12% failure rate

Based on monitoring and recording of
cervical secretions

Cervical mucus changes occur in
response to levels of estrogen and
progesterone

Spinnbarkeit – Watery thin, clear mucus becomes
more abundant and thick. Feels similar to a
lubricant and can be stretched 5+ cm between
the thumb and forefinger
Presence indicates period of maximal
fertility
Sperm deposited in this type of mucus
can survive until ovulation occurs

Cervical mucus that accompanies
ovulation is necessary for viability &
motility of sperm

Mucus alters pH by neutralizing acid
Contraceptive gels or foams
 Vaginal infection
 Douches
 Vaginal deodorant
 Medications (antihistamines dry up
mucus)
 Sexually aroused state thins mucus
 Uncomfortable touching genitals

Assess cervical mucus daily
 Avoid intercourse when first notices
cervical mucus becoming more clear,
elastic, and slippery and then for 4 days
 Instruct women on barriers to cervical
mucus assessment


BBT is lowest body temperature of a healthy
person taken immediately after waking and
before getting out of bed

BBT varies from 36.2-36.3 during menses and 5 7 days after

At time of ovulation there is a slight decrease in
temperature (fertile period)

After ovulation the BBT increases slightly and
remains until 2-4 days prior to menstruation

Fertile period is day of first temp drop or first
elevation through 3 days of elevated temp

Abstinence begins the first day of menstrual
bleeding and lasts through 3 consecutive days
of sustained temp rise
Temps are recorded on graph
97% effective if performed correctly
