Both of you. All at home, by post.

Switch on what you want. We'll tell you which tests aren't worth your money.

02

A specialist reads it back.

On video. Both of you on the call.

Doctor
What your numbers mean.

And when to stop optimising and get referred.

Dietitian
Turns the panel into food.

Not a supplement stack and a printout.

Counsellor
Included from day one.

Not something held back until things get bad.

03

One plan. Month by month.

Built on your results, not on what's trending.

Solid
Do it.

Good human evidence behind it.

Emerging
Your call.

Promising, evidence still thin.

Noise
Skip it.

Whatever the podcast said.

Every line in your plan carries a grade.

How we decide what to publish

Every claim
carries a grade.

Solid, emerging or noise, printed next to the claim it belongs to. Where the evidence is thin we say it is thin, including when the stronger claim would sell better.

Our team, our clinicians and our lab accreditations will be named here before the first cohort opens.

Straight answers

The questions people actually ask.

What is trimester zero? +
The three months before you start trying. Sperm take about ninety days to develop and eggs finish maturing over a similar window. That's the period in which both partners' inputs are still modifiable. Testing at the start of it tells you which ones are worth your effort.
What do we actually test? +
A biomarker panel for both of you: nutrients, metabolism, stress, hormones. AMH for her, a full semen analysis for him. Gut microbiome for both, vaginal microbiome for her. Optional: a two-week glucose monitor and genetic screening, including carrier compatibility between you. All at home, by post.
Does AMH tell me whether I can get pregnant? +
No. It is the most oversold number in fertility. AMH shows ovarian reserve and predicts IVF response. In women without a history of infertility, a low result has not been shown to reduce the chance of conceiving naturally. Steiner et al., JAMA 2017; ACOG guidance.
Why does he need to test too? +
Male factors are involved in around half of the couples who struggle, and men are still tested last, often after a year of investigations aimed entirely at her. Testing both of you at once is simply the faster route to an answer.
Is this a substitute for a clinic? +
No. These are screening tests. They show where you stand; they do not diagnose infertility. If your results need proper investigation, our doctor says so on the call and you get a clean export to take to your GP or clinic.
Will this guarantee a baby? +
No, and be wary of anyone who says otherwise. We sell better information, real support and a plan you can follow. Never an outcome.
Do I have to buy the box? +
No. Testing and the box are separate. Plenty of people will test, get their plan and run it themselves. The box exists because doing every swap at once is expensive and overwhelming.
What if we've been trying a while, or had a loss? +
You're exactly who this is built for. A counsellor is in the programme from day one, and the doctor will be honest about when it's time for clinical investigation rather than more optimising.
