NaProTECHNOLOGY Prematurity Prevention Program

Prematurity Prevention is a NaProTechnology clinical protocol developed by Dr. Thomas W. Hilgers for managing pregnancies at elevated risk for preterm birth. It addresses a defined set of risk factors: prior preterm delivery, second-trimester pregnancy loss, cervical insufficiency, and specific obstetric histories that indicate heightened vulnerability. The Prematurity Prevention protocol is a structured approach to identifying and supporting at-risk pregnancies from early gestation rather than waiting for preterm labor to present.¹

The protocol's components fall into three categories of intervention: structured cervical assessment, hormone-state monitoring, and supportive interventions. What those interventions consist of in a specific pregnancy is determined by the treating physician based on the patient's individual risk profile, her documented hormonal history, and her clinical presentation. NaProTechnology's restorative principle applies throughout: support the body's own mechanisms for sustaining pregnancy rather than bypassing them.²

A woman's cycle charting history, including pre-pregnancy hormone assay data documented through the Creighton Model, informs the clinical starting point. A documented luteal phase deficiency before conception is clinically relevant to early pregnancy management. The chart is not set aside at conception. It provides longitudinal context that shapes how the pregnancy is monitored and supported.

Prematurity Prevention sits within NaProTechnology's broader approach to early pregnancy loss and recurrent pregnancy loss, recognizing that the physiological vulnerabilities driving preterm birth often precede pregnancy itself. and NaProTechnology.
