The '''Creighton Model FertilityCare System''' ('''Creighton Model''', '''FertilityCare''', '''CrMS''') is a form of [[natural family planning]] which involves identifying the [[fertility|fertile]] period during a woman's [[menstrual cycle]].  The Creighton Model was developed by Thomas Hilgers, the founder and director of the ''Pope Paul VI Institute''.  This model, like the [[Billings ovulation method]], is based on observations of cervical mucus to track fertility.  Creighton can be used for both avoiding pregnancy and achieving pregnancy.

== Conceptual basis ==

Hilgers describes the Creighton Model as being based on "a standardized modification of the [[Billings ovulation method]] (BOM)", which was developed by [[John Billings (Australian physician)|John and Evelyn Billings]] in the 1960s.<ref name="Creighton Model">[http://www.creightonmodel.com/ Creighton Model]</ref> The Billingses issued a paper refuting the claim that the CrMS represents a standardization of the BOM. According to the Billingses said that those concepts are two different methods and should not be seen as interchangeable.<ref>[http://www.woomb.org/omrrca/BOMvCrMS.pdf Some Clarifications Concerning NaProTECHNOLOGY and the Billings Ovulation Method] {{webarchive|url=https://web.archive.org/web/20070928094134/http://www.woomb.org/omrrca/BOMvCrMS.pdf |date=2007-09-28 }}</ref>

== Effectiveness ==
For avoiding pregnancy, the perfect-use failure rate of Creighton was 0.5%, which means that for each year that 1,000 couples using this method perfectly, that there are 5 unintended pregnancies.  The typical-use failure rate, representing the fraction of couples using this method that actually had an unintended pregnancy, is reported as 3.2%.<ref name="Meta Analysis">{{cite journal |last1=Hilgers |first1=TW |last2=Stanford |first2=JB |title=Creighton Model NaProEducation Technology for avoiding pregnancy.
