Our evidence method
We start with what you want to know, not with whatever happens to be inside Gyna’s paid program.
Then we find the best evidence that can answer that question, including evidence that makes the answer less exciting, more limited, or more personal.
1. Find the real question
We look for recurring questions in Gyna’s private fertility community, search data, quiz responses, and conversations with members.
We use anonymous patterns, never a member’s identifying words or story.
The private-community snapshot currently ends in March 2026. It helps us understand question shapes and language, but it is not treated as live demand or a population estimate.
2. Define the boundary
Before searching, we name the people, decision, comparison, outcome, and time period that matter. Ovulation, conception, pregnancy, and live birth are not treated as the same result.
3. Show the useful truth
The short answer includes the important uncertainty. The deeper record shows who was studied, what changed, what did not, safety limits, source links, and when we last searched.
Where we look
We begin with published guidance from major health authorities, then use systematic reviews and primary studies when the question needs them.
Existing Gyna research and course claims can help us find a source, but they do not decide what the public should answer or make a weak source stronger.
A consistent answer shape
The format stays the same even when a field has to say that the research did not report something reliably.
Evidence is not all equal
More than one independent health authority states it.
This is the only bar we treat as strong enough to use in advertising.
One health authority states it in published guidance.
Solid, but it rests on a single body's reading.
A systematic review of the research supports it.
Research consensus rather than an authority's own guidance.
Our public fertility answers link to the sources behind them. If an answer has been reviewed by a clinician, that will be noted on the page.
Clinical review is separate from source checking. We will not label a page as clinically reviewed until a qualified person has reviewed that specific page.
You can open the original sources yourself, which is why every released answer keeps them beside the evidence snapshot.
Guidance changes, sources are corrected, and we can read a result too confidently. Tell us the page and sentence, and we’ll check it against the source.
