Natural Family Planning

Natural Family Planning


There are four basic types of natural family planning:
1) the Sympto-Thermal Method (STM)
2) the Ovulation method
3) the "Rhythm" or Calendar method, also known as the Ogino-Knaus method, and
4) the Basal Body Temperature (BBT) method

Each of these methods, when used to avoid or postpone pregnancy, take into account sperm viability in the female reproductive tract, which averages three days (with a range of from two to seven days) and the fertile period of the ovum, which is about 24 hours. This means the fertile period may be a maximum of seven days before ovulation to two days after, and is more typically four days before ovulation to two days after.

The following descriptions of these four methods are merely summaries of the similarities and contrasts between them. Anyone who desires more detailed information on any of the methods should consult the NFP teaching groups such as The Couple to Couple League.

Calendar Method

During the 1920s, Drs. Kyusaku Ogino of Japan and Hermann Knaus of Germany performed independent research into the menstrual cycles of a number of women, and found the following patterns;
(1) Conception is seldom possible from 20 to 24 days before the next menstruation;
(2) Conception is possible from 12 to 19 days before the next menstruation; and
(3) Conception is impossible during the 11 days before the next menstruation.

The original research of Drs. Ogino and Knaus laid the foundation for the development of modern natural family planning methods that are currently more effective than most contraceptives.

The primary advantage of the calendar method is that it is relatively easy to learn and use. A woman simply keeps a menstrual calendar for several cycles, noting when menstruation begins and ends. She then determines the longest and shortest cycles, and applies the "minus 10, minus 20" rule, which means she uses the shortest cycle to find the first fertile day by subtracting 20 days from its length, and uses the longest cycle to find the last fertile day by subtracting 10 days from its length.

For example, if the longest cycle has been 30 days, and the shortest cycle 25 days, the first fertile day will be Day 5, and the last fertile day will be Day 20.

The disadvantages of the "rhythm" method are obvious. Since it does not reflect the actual nature of the current cycle, but only an average of previous cycles, long periods of abstinence and a relatively high failure rate can be expected, especially if cycles are irregular The "rhythm" method can be very difficult to use after childbirth and miscarriage, and when menopause is approaching, because cycle lengths can be very irregular during these times.

Despite all of these difficulties, users of the "rhythm" method experience a user effectiveness rate of 91% during the first year, which is far better than most mechanical methods of contraception. The success rate is even better when the method is combined with temperature observations.
