FACTS is a group of physicians, healthcare professionals and educators working together to provide information about natural or fertility awareness based methods of family planning with the medical community.

Our goal is to share the best evidence available with our healthcare colleagues and students so they can:

Educate women and men about their fertility
Empower them to make more informed choices about family planning
Enable women to collaborate with medical professionals to better monitor and manage their reproductive health
Our Mission

To educate future healthcare professionals about evidence based fertility awareness methods (FABMs), so they may empower and engage patients to care for their reproductive health.

Our Vision
To change the culture of medicine so fertility is recognized as normal and healthy.
Our Goals
  1. Educate students, physicians, and health professionals in the basic principles of fertility awareness based methods (FABMs) and the supporting science behind their medical applications.
  2. Promote FABMs and their use in effective, relationship-centered care for women and couples.
  3. Provide a forum for clinicians, educators and researchers to share and expand the evolving body of evidence about FABMs.
  4. Foster respect and support for clinicians and students as collaborators in patient-centered reproductive health care.
Statement of Principles
  1. Fertility is a healthy aspect of reproductive physiology.
  2. Our educational approach to fertility awareness based methods (FABMs) is grounded on solid scientific evidence and ongoing research.
  3. Fertility awareness based methods can be used effectively to achieve or avoid pregnancy and to monitor and manage reproductive health. They empower women to make more informed decisions about their care.
  4. Fertility awareness based methods enable women to invite men to share responsibility for family planning, as they each contribute equally to the formation of a unique human being.
  5. Physicians and healthcare professionals trained in FABMs can work with patients to care for their reproductive health and address gynecologic disorders, including infertility, with the goal of not suppressing or destroying fertility.
  6. FACTS promotes the proven effectiveness of any fertility awareness based method (FABM) that has quality science to support its use.
Our History
Over the past 40 years, significant innovations have been made in women’s health care, particularly within the realm of reproductive science. Parallel to these advances, natural methods for monitoring fertility have been standardized and refined. This has led to more effective tracking of women’s cycles and the times of fertility. These methods can be used to achieve or postpone pregnancy, and in some cases to address underlying gynecological concerns in ways that cooperate with or restore the normal physiology and anatomy of the human reproductive system. These treatments do not use approaches that are inherently suppressive, circumventive or destructive and provide opportunities for reproductive health care that respects a patient’s right to understand and cooperatively manage their own fertility, with appropriate medical assistance. Despite advances in the science of fertility awareness based methods (FABMs) and increasing interest among women in using them, the overwhelming majority of physicians, healthcare professionals and students are not familiar or knowledgeable about them. In response to this, a group of family physicians and experts in the field of fertility appreciation founded FACTS under the umbrella of the Family Medicine Education Consortium in 2010.
