Infertility Services

Many of our client couples suffer from infertility. Some of our clients have tried for years and many have gone through a number of IVF cycles before coming onto our programme.

All our client couples who come onto our programme to address their infertility will first learn the Creighton Model FertilityCare system. They learn how to track their natural menstrual cycles and how to effectively use their fertility window for achieving pregnancy naturally.  We have seen some of these couples achieving pregnancy naturally by simply knowing their own fertility better.

“With the use of the Creighton Model FertilityCare system only, success rates between 20% and 40% can be expected within the first year of use.

This easily matches the best IVF success rate of 32.2% for ladies under 35*.”

* IVF Success Rates are listed at the end of this page.

However many others will require medical support, including both surgical and non-surgical methods, to restore and improve their natural fertility. The medical conditions that our infertility couples suffer from include unexplained infertility, endometriosis, polycystic ovarian disease, recurring miscarriages and male infertility.

While these conditions affect either the woman or the man, we focus on the combined fertility of the couple. The Creighton Model offers a medical programme, NaproTECHNOLOGY or NaPro, which aims to treat the underlying medical conditions that may adversely affect the couples’ natural fertility and improve their natural fertility.

“Considering all patient ages and diagnoses, the overall probability of having a successful pregnancy with NaPro is approximately 50%”

The success rate can be up to 80%^ depending on multiple factors including the precise diagnosis, severity of the underlying cause, history of previous fertility treatment and female age.

Read our 9 Facts About NaPro For Infertility here.

NaPro is not an option in cases of established menopause, zero sperm count or persistent bilateral blocked fallopian tubes (despite attempted surgical reconstruction). A couple will be told what their chances of success are during the initial medical consultation and it is up to them to decide if they would like to commence further evaluation and treatment.

Although there is real hope with NaPro, not all couples will conceive. All couples undergoing NaPro evaluation obtain a greater understanding of what is happening with their bodies and how they can maximize their chances of healthy pregnancy^^.

Napro & Male Factor

In our experience the male factor can be greatly improved with vitamins/supplements and lifestyle changes, i.e. without medicine.

Even if the sperm function is not ideal, the couple can raise their chances of pregnancy greatly by accurately identifying their fertility window with FertilityCare, and using that time effectively with frequent intercourses.  Some of our couples have spoken about their experiences here.

Nevertheless some couples will require medical support – i.e. drugs and/or surgical treatments.

The overall success rate for male factor infertility is around 40%. A brochure is available here.
