Infertility affects one in 16 married women in the United States where 12.7% of these seek treatment. The stress of infertility and treatment is known to impact marital satisfaction, which can be further complicated by personal and religious beliefs regarding the ethics of some assistive reproductive technologies. A morally acceptable approach to infertility diagnosis and treatment is natural procreative technology or NaProTECHNOLOGY (NPT) using the Creighton Model FertilityCare™ System. A quantitative, descriptive study utilizing demographic surveys and the Index of Marital Satisfaction found that couples using NPT reported marital satisfaction.
