FACTS is a collaborative of medical professionals, educators and supporters. We are committed to educating our colleagues and clients about fertility and ways to monitor a woman’s cycle for the purposes of family planning and health maintenance. Our success to date is due to the dedication of our members and their willingness to work together to share the best evidence supporting the use of natural or fertility awareness based methods of family planning. We invite you to become a part of our diverse team of people who are passionate about teaching others the “FACTS” about fertility appreciation.

Membership benefits include on-line continuing medical education and professional development, members’ only web-site access and discounts for FACTS conferences.

Members are expected to support our mission and vision, and work with us to help us achieve the goals of our organization. FACTS has developed a statement of principles that guide our work. Our members come from diverse backgrounds, and as such, are asked to employ the Principles of Dialogue.

FAQs
Who is involved in FACTS?
FACTS is a collaborative of medical professionals, educators and supporters committed to educating our healthcare colleagues and clients about fertility and ways to monitor a woman’s cycle for the purposes of family planning and health maintenance.  Our success to date is due to the dedication of our members and their willingness to work together to share the best evidence supporting the use of natural or fertility awareness based methods of family planning.  We invite you to become a part of our diverse team of people who are passionate about teaching others the “FACTS” about fertility appreciation by joining today.
What are some resources for teaching patients in Spanish?
The Billings Ovulation Method® (BOM) has educational materials available in Spanish, as well as numerous Spanish speaking teachers in the US, which can be located via their web-site.

Family of the America’s has developed a program to teach a method very similar to the Billings Ovulation Method by comparing a woman’s fertility to the natural fertility of the earth. The program has been translated into a number of different languages including Spanish and has been used effectively to teach women and men with very low health literacy.

SymptoPro and Couple to Couple League offer their materials in Spanish for women or couples interested in learning the sympto-thermal method.  There are a limited number of Spanish instructors, depending on your location.

The Marquette web-site also has materials available in Spanish.
