Metabolic health is the foundation of fertility โ€” for both partners. That's what we learned the deeper we went. And again and again, we met couples trying to conceive who needed real, expert guidance but couldn't access it affordably โ€” or together. One-time lab panels, conflicting opinions, generic advice, and no way to know if anything was actually working. So we built FertilityScience: fertility care designed around the couple. We track both partners' biomarkers over time and turn them into a personalised, evidence-led preconception protocol โ€” so you decide on trends, not guesswork. HOW IT WORKS โ€ข Upload any lab report โ€” from any lab. We read it automatically and organise 20+ fertility-relevant biomarkers: hormones, vitamins, metabolic and reproductive markers. โ€ข See where you stand. Every marker is scored against reference ranges, with clear "optimal, in range, needs attention" status โ€” no more decoding PDFs alone. โ€ข Get your protocol. A personalised daily plan across food, supplements, movement and lifestyle, generated from your results and reviewed by our team before it reaches you. โ€ข Do it together. Link your partner, see both of your progress side by side, and prepare for pregnancy as a team โ€” because fertility is shared biology. โ€ข Retest and compare. Follow your protocol, test again, and watch your markers move. Measure, improve, remeasure. WHAT'S INSIDE โ€ข My Health rings โ€” your biomarker picture at a glance, updated with every report โ€ข Personalised protocol โ€” daily tasks with the "why" behind each one โ€ข Cycle tracking that learns your cycle, not a fixed 28-day template โ€ข Monthly insights โ€” what improved, what changed, what to focus on next โ€ข Ask a doctor โ€” post questions and get answers from qualified specialists โ€ข Partner view โ€” two people, one shared journey MADE FOR Couples trying to conceive, anyone preparing their body for pregnancy, and partners who want to understand โ€” and improve โ€” their reproductive health together.
