Instruction in the Symptothermal Method of natural family planning

SERENA is an organization of trained and nationally accredited volunteers who are users of the Symptothermal Method. Our teacher-couples are specially trained to give instruction in fertility awareness and in the effective practise of the Symptothermal Method. Specific instruction is available which meets the needs of women and couples in various situations that occur during their reproductive lives. Our teacher couples can offer you personalized guidance and ongoing support.

Typically a consultation consists of one or two sessions with an certified SERENA teacher-couple.

The first step is to provide a basic understanding of human fertility and to teach the basic rules for following the Symptothermal Method and interpreting the data. Then, after reviewing symptothermal charts which illustrate various real life situations, the couple will be given the opportunity to use their new found knowledge by filling in a practice chart as part of a review of the rules of interpretation.

A couple will learn to observe and chart natural changes in a woman’s body that signal whether she is fertile or infertile on any given day of the menstrual cycle. With this knowledge, a couple can determine when they are fertile. Through loving dialogue a couple can choose, each menstrual cycle, to avoid a pregnancy or to conceive a new member of their family.

Why the emphasis on meeting as a couple? In my situation, this is not possible. Can I still meet with a Serena Teacher-Couple?

In SERENA's sixty years of teaching experience, teaching couple to couple provides the best outcome. Both members of the teacher-couple bring their life experience, viewpoint and skills to the teaching session. The couple receiving instruction can both ask for clarification, and will have the opportunity to start this new enterprise with a common experience. The sessions a confidential and participants are not expected to divulge any personal information.  Depending on circumstances, we will meet with an individual, either a woman, or as has happened, a man.


Your teacher-couple remains available for additional consultations, as needed. There is no charge for further education - only for materials as required. You can contact your teacher-couple by phone or e-mail to ask them to repeat or to add to information given, and to help you interpret your symptothermal chart if questions arise. Consulting with an accredited teacher-couple is encouraged when difficult situations or changes in life arise. These follow-ups are an essential step toward successful use and confidence in the method.

The best way to learn the Symptothermal Method is in a face-to-face meeting with an accredited teacher-couple.
