WOOMB International

Who We Are


WOOMB International – World Organisation Ovulation Method Billings – continues the work of its founders the late Drs John and Evelyn Billings who established the Billings Ovulation Method® of natural fertility regulation. The Billings Ovulation Method® is a Method which empowers women, through knowledge of their patterns of fertility and infertility and the time of ovulation, to achieve or postpone pregnancy and to monitor their reproductive health.

WOOMB International has Affiliates in many countries. These national bodies are responsible for training and accreditation of teachers of the Billings Ovulation Method® in their own country. 

WOOMB International works to ensure that wherever in the world the Billings Ovulation Method® is taught, it is the authentic Method as developed by Drs John and Evelyn Billings, without alteration, and that only WOOMB International approved teaching and training materials are used for this purpose, including materials translated into languages other than English.
