Tulsi Patel, Director of Product and Technology, HertilityLorna Brightmore, Head of Data and AI, HertilityJack Pickard, Head of Engineering, HertilityWhat makes Hertility's data set unique: seven years of linked symptoms, blood tests, and pelvic scans from over a million womenHow Gyn.AI uses a Bayesian network to give clinicians probability-based diagnoses instead of binary yes/no callsWhy showing clinicians the reasoning behind a diagnosis—not just the label—builds trust and speeds up triageGuarding against automation bias with holdout sets and independent, fresh-eyes reviewInside the scan automation pipeline: classifying ultrasound images, detecting follicles, and measuring ovarian volume more precisely than manual methodsUsing an agentic loop to check AI-drafted clinical letters against patient data and catch hallucinations before a human sees themThe infrastructure challenge of securely piping DICOM ultrasound images from third-party scan providers into Hertility's systemsHow Hertility handles PII and PHI: pseudonymization, data minimization, and running models in-house on AWS BedrockWhy treating healthcare regulation as a product requirement from day one makes AI products more scalable, not slowerProbabilistic, transparent AI outputs build more clinician trust than binary classifications.Guardrails against automation bias are as important as the model itself.Data minimization and in-house infrastructure make it possible to build AI responsibly with sensitive health data.Treating regulation as a design constraint from day one makes AI products more defensible and scalable, not slower.Hertility — At-home hormone testing and reproductive health diagnostics for women in the UK and IrelandAWS Bedrock — The platform Hertility uses to run LLMs in-house under its own governance and regulatory controlsPyTorch — The foundation for Hertility's in-house image classification and contouring models00:13 What Hertility Does
