About Justisse

Founding and history

The Justisse Method of fertility awareness and the Justisse Fertility Management Practitioner training were developed in 1987 by Geraldine Matus. The intention was to provide information and guidance for sexual and reproductive health management with respect to individual rights and decisions. Over the years Justisse evolved into Justisse College International, a non-profit corporation dedicated to training Holistic Reproductive Health Practitioners (HRHPs). Starting in 2011, a group of HRHP graduates began training to become Justisse College faculty members and collaborators in managing the college in a non-hierarchical manner. See our current faculty and staff below.

At Justisse we provide comprehensive, purposeful and meaningful training for fertility awareness educators, aiming to have our graduates exemplify ethical standards of clinical and educational practice. Our courseware is an ever developing, multidisciplinary journey through the endocrinology, anatomy, physiology, history and life stages of the female body, reflecting the most scientifically accurate knowledge currently available, while also encouraging a functional medicine approach, scientific literacy and self-reflection. A Holistic Reproductive Health Practitioner understands the connection between menstrual cycle and general health, the deep significance that fertility awareness has in women’s lives, as well as issues of reproductive justice.

The Justisse Method

The Justisse Method is a standardized system for learning fertility awareness which allows for self-management of reproductive health, contraception, preconceptive planning, and conception timing. With the Justisse method you can avoid artificial contraception, improve your chances of a healthy pregnancy, and gain an invaluable day-to-day insight into your hormonal health.

In the Justisse Method, we chart and interpret the three scientifically proven, primary signs of fertility: cervical mucus secretions, basal body temperature and cervical position, and relate to these signs in accordance with our reproductive goals. The method can be implemented as a symptothermal (with daily measurements of basal body temperature) or mucus-only method. The Justisse method does not involve calculation rules or algorithms, but instead teaches the charter to observe, in real time, the scientifically verified signs of fertility and infertility that the female body demonstrates during the menstrual cycle, as well as understand the significance of deviations from their normal. The pedagogical process of learning and using the Justisse method ensures body literacy, and provides an estimated perfect-use efficacy rate between 97.6 and 99.6 % for the symptothermal version, and between 96.6 and 98,9 % for the mucus-only version (Peragallo Urrutia et al., 2018, Duane et al., 2022). Read more about the scientific basis and efficacy of Justisse and other similar fertility awareness-based methods here.

The Justisse method is best learned from Justisse Practitioners. Learning with a Holistic Reproductive Health Practitioner ensures that the method is taught properly, that the user is able to ask all the necessary questions to use the method with high efficacy, that they are witnessed in their learning journey and have personal support when experiencing changes in their menstrual cycle health. Our HRHP:s are committed to reproductive justice, supporting a holistic, psycho-physiological approach to managing and enhancing sexual and reproductive health throughout the female life cycle.
