Today, fertility management is an issue impacting 99% of the adult population in the
USA. Nearly all sexually experienced American women have used some method of
contraception to manage their fertility: 99% in 2006–2008.  Oral contraceptives are the most
popular method but often produce side effects. The Creighton Model Fertility Care System
(CrMS) is an alternative with no side effects and is comparatively effective. The CrMS has
method and use effectiveness rates comparable to those of oral contraceptives (99.78%-99.66%,
97%-92% respectively for OCs and 99.5%, 96.8% respectively for CrMS). [31,22] It is
intriguing that the CrMS has only one fifth to one third the discontinuation rate after one year
that oral contraceptives do (11.3% for CrMS compared to 54.1% or 30%  for OCs).
The conclusions of this study suggest that patients appreciate learning about their biology
and are satisfied and confident using this biology to manage their fertility through FABMs such
as the CrMS. This may be a fertility management method with a wider appeal for patients
looking with any of the following characteristics which were appreciated by the participants of
this study: strengthening of communication and relationship with their partner because of shared
fertility management responsibility, the natural basis of the method, the relief of problems
experienced with hormonal birth control, the alignment with religious and moral values, the
versatility of the method to both achieve and avoid pregnancy, and increased diagnostic power
for women‟s health and infertility issues, and the method‟s low monetary cost, effectiveness, and
simplicity. Each of these areas of appreciation may contribute to the lower discontinuation rates
of CrMS users compared to hormonal birth control users. The CrMS could be an effective
fertility management method for hormonal birth control users who are dissatisfied with their use
of hormonal birth control as a fertility management method.
