Couple to Couple League (CCL)
Sympto-Thermal Method

CCL teaches a sympto-thermal method of natural family planning, which basically means it combines both mucus and temperature recordings to indicate naturally-occurring fertile and infertile phases.

These “signs” are easily noticed by any woman who has learned to watch for them. As the signs are observed, they are recorded on a chart. The chart provides a daily record that can be used to identify the days of fertility and infertility. Once the fertile and infertile days have been identified, the couples apply “rules” that they learn in class and that are explained in CCL’s Student Guide to frame the boundaries between the phases of the cycle and use the system to either achieve or avoid a pregnancy. CCL also offers Cycle®ProGo, an application program for easy on-the-go, online charting. For more information about CCL’s sympto-thermal method, visit
