The fertility use case connects cycle context, metabolic state, stress, recovery, prior care history, referrals, and SETPOINT feedback into a calibrated Twin.
Cycle · metabolic · stress · sleep · labs · history
Cohort priors · reference ranges · calibration state
Confidence · trajectory · transition readiness
Preparation · practices · outcomes · recalibration
Cycle regularity, phase context, symptoms, and timing continuity.
Energy, weight trend, glucose-related context, inflammation, and recovery.
Sleep consistency, stress load, resilience, and nervous-system regulation.
OBGYN history, referrals, fertility consults, lab context, and prior interventions.
Practice completion, lifestyle readiness, education, and support behaviors.
Observed changes update confidence, trajectory, and model calibration.
Builds longitudinal readiness history before specialty care.
Preserves context when patients move from OBGYN to fertility workflows.
Tracks practices, symptoms, adherence, and outcome signals.
Updates Twin confidence and future readiness interpretation.
DT4H does not diagnose infertility or replace fertility specialists.
Readiness state is a bounded modeling signal, not deterministic prognosis.
This use case is valuable when patients transfer from OBGYN care into fertility or IVF pathways.
