Introduction: NaPro Technology is a method of infertility treatment based on the principal that both, female cycle and male spermiogramme, can be normalized by administering drugs, using a changed diet and various procedures so that a couple can conceive a baby naturally. A nurse with good knowledge and experience, taking a holistic approach, can give advice to couples facing infertility. Purpose: The aim of the thesis is to introduce a role of a nurse in treating infertility via NaPro Technology. We have studied a female cycle and her fertility, the FertilityCare™ System of natural family planning and infertility treatment with help of the latter (NaPro Technology). We have explored how a FertilityCare™ Nurse consultant with her/his knowledge and wholistic approach can give diet- and nutrition advice and also tips for a healthy lifestyle. We have researched on which healthcare areas a nurse with extra education or training can help find better solutions for female infertility. Methods: In my final thesis we used a descriptive research methodology. The literature review was made in 2015-2017. We studied Slovenian and English professional literature. Various books by Slovenian and foreign authors as well as professional articles, general overview articles and scientific articles were selected. Literature from 2008 to 2016 was used. Older articles were used just as a historical reference point. Results: Infertility is a painful struggle for a couple. We observed that couples treated by NaPro Technology were satisfied with the treatment, and when compared to other methods, NaPro Technology was a comparatively successful and favourable choice. We also found out that abroad there are specially trained nurses in attending to couples on their journey through infertility treatment. Discussion and conclusion: NaPro Technology has advantages and disadvantages. Couples can make use of it right after having discovered their infertility problems. In Slovenia there are two active NaPro trained doctors for the time being. The origin of the method has ties to Christianity, which is very often a hot-button issue, since the method is accessible to married couples only. NaPro Technology treats specific infertility problems. The aim is not a pregnancy at any cost, but a potentially successful infertility treatment.
