Pregnalyze is powered by 54 peer-reviewed clinical studies across obstetrics, gynecology, reproductive endocrinology, epidemiology, and perinatal medicine.
Our model uses:
Published gestational-age miscarriage curves
Odds ratios / risk ratios from clinical studies
Protective and risk-increasing modifiers
Validated ultrasound milestones
Pregnalyze does not diagnose or predict individual outcomes. It provides a structured, research-based estimate to help users understand how known factors influence miscarriage risk statistically.
2. How the risk estimate works
We combine three components:
Baseline miscarriage probability
Based on:
Gestational age
Whether a fetal heartbeat has been detected
Week-by-week statistical miscarriage curves
Risk-increasing factors
Examples include:
Maternal age
Previous pregnancy loss
BMI and metabolic factors
Autoimmune conditions
Infections
Certain medications
Substance exposures
Some uterine conditions
Paternal factors
Each factor applies a published odds ratio from clinical research.
Protective / risk-reducing factors
Examples:
Previous live birth
Fetal heartbeat detection
Some treated medical conditions
These data points statistically reduce estimated miscarriage probability based on the literature.
3. What Pregnalyze does not do
To ensure clarity and safety:
❌ We do not provide medical advice or diagnosis
❌ We do not replace a doctor, midwife, or ultrasound evaluation
❌ We do not use AI/ML prediction models
❌ We do not access personal medical records
❌ We cannot predict individual outcomes
❌ We cannot tell whether a pregnancy will continue or miscarry
