The Creighton Model teaches women to observe certain biological signs to monitor their own gynaecological health, and to identify times of fertility and infertility. These biological signs include cervical mucus and bleeding patterns, and can be observed and analysed in all types of menstrual cycles. These signs are charted daily to give a picture of the woman's individual cycle.

Doctors can use the fertility charts which couples are taught to keep as the basis for further investigations if needed.

Blood tests for Oestrogen levels prior to ovulation and for both Progesterone and Oestrogen levels after ovulation, ultrasound follicular tracking, and other diagnostic procedures, can be accurately timed according to the woman's cycle, using the data recorded on a couple's fertility chart. This allows doctors to make a more precise diagnosois of abnormalities, e.g. subtle hormonal deficiencies, various ovulation defects etc.

[edit] Uses

As a form of fertility awareness or natural family planning, the Creighton Model may be used to avoid pregnancy, or to increase chances of conception depending on the couple's intentions. When used to avoid pregnancy, the perfect use effectiveness rate is reported at 99.5% in the first year.[1] In studies of similar methods, the typical failure rate is defined as the number of pregnancies among couples who told researchers they intended to use the method to avoid pregnancy. In clinical studies of the Creighton Model, however, most pregnancies were excluded from the failure rate calculation because researchers believed the affected couples had used the method to deliberately attempt pregnancy.[2] Therefore, typical failure rates of the Creighton Model cannot be compared to typical failure rates for similar methods.

The Creighton Model System is used in conjunction with Naprotechnology, which aims to restore fertility naturally, by identifying and then correcting the underlying causes of the couples' infertility, rather than regarding it as a disease, as IVF does.

[edit] Treatment

Use of natural hormones and other medications to correct any hormonal disturbances or ovulation abnormality.
Use of medications if necessary to correct any other abnormalities e.g. cervical mucus deficiency, biochemical or haematological deficiencies, endocrine (glandular) deficiencies etc. to restore normal physiologic function, and thereby enhance fertility.
Referral to a gynaecologist if there are physical abnormailities needing surgery, for example
- blocked fallopian tubes
- endometriosis
- adhesions

[edit] History

The Creighton Model was developed at the Pope Paul VI Institute which was itself set up to support medically the directives given by Pope Paul VI in his encyclical 'Humanae Vitae: On the Regulation of Birth'. Research leading to the development of the Creighton Model System began in 1976 and the system was first fully described in 1980.[3]
