Title: Natural Family Planning

Natural Family Planning
Natural Family Planning
Natural family planning (NFP) describes various
modern methods of achieving or avoiding pregnancy
based on knowledge of the signs and symptoms of
human fertility. It requires abstinence from
genital contact during the ovulatory (fertile)
phase of a womans cycle to avoid pregnancy.
Natural Family Planning
The idea behind natural family planning is very
simple. A woman is fertile for only about 100 to
120 hours during a month. Let's call this time
period the "window of fertility." By avoiding
sexual intimacy during the window of fertility,
pregnancy can be avoided. This method can also
help achieve pregnancy by understanding the
fertility cycle better and learning when the
probability of conceiving is highest. The
question that various natural family planning
methods are trying to answer is "How do I
determine exactly when the window of fertility
starts and ends?"
Fertility The ability to become a parent
Cycle A period of time from one menstruation to
another. It varies from 1 every 20 days to 1
menstruation a year, or twice a year, etc.
The Four Seasons of the Fertility Cycle
Late Summer Early infertility
Fall Ovulation time
Early Summer Menstruation
Spring Late infertility
Winter Preparation time for ovulation
Cyclic Fertility
A womans fertility is cyclic. She is not always
fertile, but only periodically. Her fertility
cycle begins at puberty (11-15 years).
Ovulation or fertile phase
Early non-fertile phase (pre-fertile phase)
Late non-fertile phase (post-fertile phase)
Not all cycles are the same. A woman may have
what is called a long cycle, or a short
cycle, or a medium cycle. Moreover, a womans
cycle is not always regular. Some months she may
be medium, others she may be long, etc.
Long Cycle
During a long cycle, the early non-fertile phase
is long.
Short Cycle
In a short cycle, the early non-fertile phase is
Fertile phase and ovulation
Early non-fertile phase (pre-fertile phase)
Late non-fertile phase (post-fertile phase)
The pituitary gland is the master hormonal gland
of the human body, located at the base of the
brain. It sends signals to the thyroid gland,
adrenal glands, ovaries and testes, directing
them produce thyroid hormone, cortisol, estrogen,
testosterone, and many more.
Stress can delay ovulation
  • Positive Stress
  • Christmas
  • Vacation
  • Birthday
  • Negative Stress
  • Exam
  • Illness
  • Death in the family

If the oocyte (ovum) is not fertilized within 24
hours, it will disintegrate.

In the early non-fertile phase of a womans
cycle, the passageway from the vagina to the
uterus is closed by thick mucus. Sperm are
unable to pass through the cervix.
Sperm appear much larger than they would be in
The cervix is completely open during the
preparation stage of the fertile phase
In the fertile phase, the passageway from the
vagina to the uterus is open. A slippery-type
mucus assists the movement of sperm through the
cervix and nourishes the sperm.
Once the oocyte is released, the cervix begins to
After the fertile phase ends, the cervix is again
closed off by a thick-mucus plug, blocking the
cervical canal. Sperm are unable to pass through
the cervix. This late infertile phase is
followed by the menstrual phase.
It takes three days for the cervix to close
Role of Cervical Mucus
  • Nourish sperm, that is, keep it alive. Sperm can
    live up to 3-5 days in this environment. When
    there is no mucus, the sperm will die quickly
    for they can live up to an hour without mucus.
  • Eliminate weaker sperm or damaged sperm. Only
    the best quality sperm will reach the oocyte.

Role of Cervical Mucus
  • Provide transportation so they can move towards
    the fallopian tubes.
  • Finally, to let the woman know when her fertile
    time starts and ends.

Days of Bleeding

Length of menstruation depends on the thickness
of the lining of the uterus (endometrium).
Usually 5 to 7 days.
Pre-fertile phase

is a cervical discharge that is the same every
day. It does not vary. It will be sticky and

Feels wet and slippery. Mucus might be
sticky at first, but it changes, becomes more
stretchy and transparent. Everyday the mucus is
different, becoming more and more oily and

Notice that there is no early non-fertile phase
or pre-fertile phase.

Adolescent Cycles
Fertile Cycle Mid-Cycle Bleeding. . Caused by
high levels of prolonged estrogen before ovulation
Untreated mid-cycle bleeding might lead to anemia
Adolescent Cycles
Fertile Cycle Delayed Ovulation Several
patches of fertile signs finally ending in
ovulation. Ovulation is confirmed by the number
of days from the last patch of signs until the
end of the cycle (11-16 days). Ovulation is also
confirmed by the changing mucus pattern which
ends in slipperiness.
Adolescent Cycles
Anovular Cycle Several patches of fertile signs
but no ovulation. The count between the last
patch and the end of the cycle will be less than
10 days or more than 16 days.
The cycle is quite challenging because ovulation
might actually take place. However, the lutheal
phase is too short and pregnancy cannot be

complicated at first, but it is very simple and
easy to get used to.

Threats to fertility
STDs (I.e., chlamydia) One attack of chlamydia
can leave you with a 35 chance of infertility,
two attacks will raise that number to around 50.
A third attack of chlamydia will very likely
render a woman infertile. Abortion The pill (at
least for some adolescents) CONTRACEPTIVE PILL
LINKED TO CERVICAL CANCER Oxford University study
finds substantial increased risk British study
links cervical cancer to long-term use of the
contraceptive pill. Researchers from Cancer
Research UK's epidemiology unit in Oxford
reviewed 28 studies covering 12,500 women. They
found the longer a woman took the pill, the
greater her risk of developing cervical cancer --
with a 10 increased risk of if they took the
pill for 5 years or less, 60 for 5 to 9 years'
use, and 100 greater risk (i.e. double the risk
of a non-pill-using woman) if they had taken it
for at least 10 years.

Problems with the Pill The Pill has been proven
to produce blood clotting defects. These have
resulted in thrombophlebitis, pulmonary embolisms
(blood clots which lodge in the lung and may be
fatal), strokes, heart attacks and blindness. A
more complete listing in the FDA patient warning
brochure lists 18 other diseases or health
problems that have been associated with the Pill,
including cancer. The mortality risks for women
taking the Pill are higher than those for
  • Breast Cancer
  • For those women starting the pill before 20 yrs
    old, the risk of developing breast cancer was
    820 higher than for healthy non-users of the
    same age.
  • For women starting pill between 20-25 years,
    relative risk was 180 higher than healthy
  • Other researchers cite the risk of breast cancer
    for young women (less than 20 yrs old) is
    200-480 higher than for non-pill users.
  • In one study of 918 Dutch women diagnosed with
    invasive breast cancer, 85 had used the pill at
    some time.
  • Even 3 months use of the pill has been reported
    to be associated with 100 increase in breast
  • For more than ten years use, breast cancer risk
    increased by 310.
  • women with breast cancer, who at an early age
    have used oral contraceptives, have larger breast
    tumours and a worst prognosis compared with later
    (pill users) and never users.

  • ie a x3 fold reduction in Japan. Australia/USA
    have a pill history of 30 years with identical
    breast cancer statistics. Industrialised Japan,
    has no pill use, reports one third the rate.
  • (Note With use of Depo-Provera (DMPA) "Use for
    two years or longer before age 25 was associated
    with a significantly increased risk of breast
    cancer" (ie 360 increase)
  • Source Contraceptive Pill Side Effects.

  • Cervical Cancer
  • Pill use in women less than 20years old means
    280 higher risk of cervical cancer
  • In women 20-24 years, its 70 higher.
  • In women 25-29 years its 40 higher.
  • Another study cites increased risk of 250 for
    cervical cancer amongst pill users.
  • Longer term users(6-12 years) 100-340 increased
    risk of non-users cervical cancer.
  • However, one of these studies showed women who
    used the pill for only 1-6 months had a 190
    increase in cervical cancer than non-users.
  • Clinical evidence cites the pills role in
    activation of and enhancing HPV (Human Papilloma
    Virus) in initiation of cervical cancer.
  • Source Contraceptive Pill Side Effects.

  • Deep Vein Thrombosis (DVT)
  • Risk of DVT increased by 600-900 (ie 5-8 fold)
    compared to non-users in users of 3rd generation
    progestagen pills (eg containing gestodene eg
    Femodene, Minulet, Tri-minulet, or containing
    desogestrel eg Marvelon).
  • Across all age groups, use of the 3rd generation
    pill brands had a 770 greater DVT risk than
    non-pill users.

  • Second generation progestagens such as
    levonorgestrel and norethisterone have 120-280
    increase risk of DVT.
  • For teenagers aged 15-19yrs risk of DVT " for
    the desogestrel-containing oral contraceptive was
    7-fold higher than that of the levo-norgestrel
    containing products among women aged 20-24 the
    risk was 4-fold higher.
  • IMPORTANT! Note that this x7 increase was
    relative to 2nd generation users not non-users!!
    Therefore, by computation, risk for 15-19yr olds
    compared to non-users is (120-280) x 7 x
    15-26 fold risk!!
  • A x50 fold increase risk of DVT for users
    carrying a blood clotting factor V Leiden
    mutation.This occurs in 5-15 of European women.
    Note mechanism gestodene causes decreased
    oestrogen metabolism in liver leading to
    accumulation in body leading to increased DVT

Infertility after pill-use Women may not
conceive for up to 48 months or longer depending
on age This is due to atrophy of the mucus
secreting glands thus preventing sperm
transport. Note Fertility drugs cause
hyperstimulation of the ovaries, leading to
increased ovarian cancer of the ovary due to
increased minor trauma of the covering
epilthelium. The pill, and pregnancy, and breast
feeding cause a rest in ovulation, thus
associated with a decreased incidence of ovarian
cancer. Some family planning advocates defend or
advocate pill use because of the associated
decrease in ovarian cancer rates (0.2 risk). To
do so in light of the appalling side-effects of
the pill documented is a woeful ignorance of the
facts or a deliberate and cynical act of
injustice to women. Source Contraceptive Pill
