How the Conceivable Score works
A prioritization tool, not a fertility grade.

Is the Score a pregnancy predictor?
Not currently.
Score v2026.10 · Not yet prospectively validated
The Conceivable Score is a proprietary prioritization and tracking tool. Historical Conceivable data generated useful research questions, but the current Score has not yet been prospectively validated as a pregnancy-prediction instrument.
That is something we intend to test.
See what Conceivable is studyingThe one distinction that matters
Score is where to look.
Report is what may be driving it.
The Score
Points to where.
The domains that deserve attention, clarification or tracking.
Illustrative example. One domain flagged, not all five.
The Report
Explains why.

What may be driving it
- Energy availability
- Sleep
- Hormones
- Training load
Illustrative example
History the Score doesn’t use
- PCOS
- Dietary patterns
- Other history
It does not tell you whether you are fertile or infertile, calculate your chance of pregnancy, or replace a medical evaluation.
What does the Score measure?
The current Score uses 14 answers from the free assessment and organizes them into five domains. It combines them into one number on a scale of 20 to 100.
Domain · 1 of 5
Energy
Energy levels, digestion, sleep quality and hours of sleep.
Domain · 2 of 5
Blood
Cycle length, days of bleeding, clotting and spotting between periods.
Domain · 3 of 5
Hormones
Period pain and PMS.
Domain · 4 of 5
Temperatures
Whether and how you track your waking temperatures.
Domain · 5 of 5
Stress
Your stress level and, if you know it, your average heart rate variability (HRV).
The five domains overlap because human physiology does too. They are organizing lenses, not five diagnoses.
Missing information
Unknown is not abnormal.
If you don’t track temperature, the Temperatures domain is shown as Unknown rather than weak. If a piece of information hasn’t been measured, Conceivable shouldn’t invent an answer. Missing data are a gap, not a finding.

×Not how Conceivable does it
Not how it works: Missing temperature scored as a weak Temperatures domain.
✓How it works
If you track temperature, the Temperatures domain is scored from your answers.
If you don’t track temperature, the Temperatures domain is shown as Unknown, not weak.
What does the Score not use?
The current Score does not automatically score everything you tell Conceivable. It does not currently use:
- Wearable measurements themselves
- Lab results
- Compliance or engagement
- How often you log or check in
- Every diagnosis or health-history detail you provide
Conditions such as PCOS, dietary patterns, exercise, photos and other history can still inform the personalized Conceivable Report and other Conceivable tools without changing the Score itself. The Score changes only when your answers change.
Effort does not earn points.
What does a higher or lower Score mean?
A lower Score
More signals need attention, clarification or tracking.
It never means you cannot conceive.
A higher Score
More of your current answers fit the pattern the system treats as a target.
A higher Score does not mean
- A higher percentage chance of pregnancy
- Higher ovarian reserve
- Open fallopian tubes
- Normal semen
- Absence of endometriosis
- Guaranteed ovulation
- Guaranteed pregnancy
The Score tells you where to look. The Report helps explain why.
Does it look at combinations?
The current Score measures signals. The research question is whether the pattern matters more than the parts.
Not yet. Today’s Score does not weigh how signals interact.
Today
Signals
added up
The current Score evaluates answers within each domain and then combines the five domains.
Illustrative example.
The research question
One of our central research questions is whether constellations of signals carry more information than single inputs alone. That is a research goal, not a feature of the current Score.
For example
High training load may mean something very different in someone who is well fueled and well recovered than it does alongside exhaustion, poor sleep and cycle changes. Testing those interactions is part of Conceivable’s research program.
How is the Score being validated?
Validation is planned, not complete. These are five questions the Score ultimately has to answer, each one harder than the last.
- 01ContentAre the inputs relevant to reproductive health?
- 02ConstructDo the domains relate to independent measures?
- 03ResponsivenessDoes a change reflect more than more engagement?
- 04PrognosticDoes it predict outcomes, after accounting for age?
- 05IncrementalDoes it add beyond established predictors?
Until then, use the Score to prioritize and track. Not to predict pregnancy.
Is today’s Score the same as the original 2014–2016 Score?
No.
2014–2016 Score
A different instrument that included compliance measures. A 2026 re-audit of the surviving pilot data found its apparent improvement was driven by data filling in during week one. From week one onward it was flat: 46 to 46, p = 0.83.
That improvement claim has been retired
Score v2026.10
No points for compliance. That is why versioning and prospective validation matter.

Conceivable Score v2026.10
Prospective validation: not yet performed
- Inputs
- 14 answers from the free assessment.
- Domains
- Energy, Blood, Hormones, Temperatures, Stress. Organizing lenses, not diagnoses.
- Scale
- 20 to 100. We don’t publish the point value of each answer.
- Missing information
- Shown as Unknown, not scored as weak.
- Weights
- From the Conceivable framework and founder Kirsten Karchmer’s clinical experience. They are not yet empirically derived from pregnancy outcomes.
- Calibration
- Calibrated in September 2026 against 209 real assessments, so scores spread across the range. That is calibration of the scale, not pregnancy-outcome validation.
- Evidence status
- We’re documenting which parts are supported by published evidence and which remain expert-derived. See how Conceivable evaluates evidence and the Conceivable Evidence Library.
- Versioning
- Every Score belongs to a version. When the algorithm changes, the version changes.
