Get tested + 3–6 month protocol + re-test = solved
Seven things can affect this. You've probably been checked for one.
The male half of fertility, finally measured properly. Seven domains, printed reference ranges, and a re-test that shows whether it moved — including when nothing did.

How it works
Four steps, start to finish.
Assessment
A 4-minute quiz on your phone. That is all.
Testing
Your report names the tests you need and where each one is done. You book them yourself.
Protocol
Targeted formulas, an AI buddy for every question, and a coach who calls.
Re-test
The same markers, measured again. Proof, not a promise.

The assessment
Seven domains, in plain language.

B12 · Zinc · Vitamin D · Folate
Metabolic
Watch · 5.2/10
Insulin · Belly fat · Testosterone
Recovery
Watch · 4.6/10
Sleep · Cortisol · Stress load
Hormonal
Watch · 4.0/10
LH · FSH · Testosterone signal
Infection
Clear · 3.4/10
Silent inflammation · Often no symptoms
Structural
Clear · 3.0/10
Varicocele · Blockage · Imaging first

What we measure
One test for everyone. The rest only if your answers point there.
Every man gets the same at-home kit and nothing else by default. The domain tests below are ordered one at a time, and only when the assessment finds a reason.
Concentration, motility, morphology, volume and vitality, read against WHO 2021.
What the semen analysis reads, and what each line tells you
Ranges are the WHO 2021 lower reference limits — the 5th percentile of men whose partners conceived naturally inside a year. One in twenty men who have fathered a child sits below them. Below a line is not infertile, and above it is not fertile.
None of these arrive with the kit. Each is ordered only if that domain scores high enough in your assessment to warrant it — and most men are never sent for any of them.

A kit to your door, a courier the same morning. A partner lab only if you want one.

Plain packaging, no brand on the box, no calls unless you ask. Your report moves only when you move it.

Anything sensitive is kept out of the report you might show a partner or a clinic. Delete your record any time.
This is how you stop guessing about timing.
The first test tells you where you stand. The second tells you whether ninety days moved it.
The protocol
What you get, in two parts
Sequenced, not stacked. Two formulas ship to every man; the other four fire only on their own thresholds — and never more than two things arrive in a day.
Most of what comes up over ninety days is a small question at an odd hour. Ask it here and get an answer — and when it is not a question software should answer, it goes to your coach instead of being guessed at.
Two formulas for every man. Four more only if your scores call for them.
We do not personalise the formula — we personalise the pathway. The spine ships to everyone; the arms fire on their own thresholds, and never a shelf of bottles you cannot explain.

What changes, when
Nothing worth judging before month three.
Sperm take about seventy-four days to make, so the first two months are honest groundwork rather than results.




The proof
Everything measured at the start, measured again at day 90.
One man’s file. The left number is where he started and the right is where he ended — the same questions, the same lab, the same scale.
The same nineteen questions, scored the same way. The pale bar is day 0, the solid bar is day 90 — and domains are still ranked, never added up.
The five lines every man gets, read against WHO 2021 both times. Sperm made after day 90 were built under the new conditions — which is what makes this the first fair comparison.

Optional, and only for the men whose assessment flagged that domain — most never have these at all. Where they were ordered: same lab, same units, read twice.
Sample figures, not a promise. What we commit to is asking the same questions and measuring the same things again on the same scale — and showing you the comparison even when nothing moved. Structural did not move here, and that is exactly the kind of result we still show you.
Where we stop
Some of this is a doctor's job, and we will say so.
Some men who finish the assessment are pointed to a doctor instead of a product — and we say so plainly. You keep the report either way, so nothing has to be repeated.
Four of the seven domains sit inside what a ninety-day protocol can reach. These are the ones we take on.
Each is scored at day 0 and scored again at day 90. If it did not move, we say that too.
The other three are a clinician’s job, not a supplement’s. If your result points that way we say so, and we do not sell you a protocol in the meantime.
in that case
We name it in plain words and hand over your full report, so the clinic is not starting from zero.
Honest expectations
Three ways this goes. You are told which on day one.
The assessment ranks seven domains and the highest one decides what happens next. One of the three outcomes is that we sell you nothing at all.
Oxidative · Nutrient · Metabolic · Recovery highest
These are the four domains a ninety-day protocol actually reaches, so there is nothing to wait for and nothing to buy before you begin.
If day 90 shows nothing moved, the test is on usHormonal highest
A hormonal axis cannot be acted on sensibly without bloods. We name the panel, the lab and the price — and make nothing on any of it.
Protocol only after the numbers come backStructural or Infection highest
Neither is moved by a supplement. Selling you one here would cost you the months that actually matter.
You keep the full report to take with youFour things worth knowing before you start
Sperm take about seventy-four days to form and another ten to fourteen to arrive. Anything promising a result in four weeks is promising something that cannot happen.
The WHO figures are the 5th percentile of men whose partners conceived naturally inside a year. One in twenty men who have fathered a child sits below them — and being above them is not a clearance either.
Then no single lever resolves it, and we say so rather than selling you more. The protocol is sequenced, not stacked.
Continue, change strength, or stop. A quarter of semen analyses come back normal and get called unexplained; we would rather show you a flat result than let that happen twice.
The assessment is a wellness screening instrument, not a diagnostic test. Nothing here diagnoses, treats, cures or prevents any disease.
Support
A coach who calls you. Ranges a medical director set in advance.

A booked call every week to begin with, then fortnightly once you are settled — and a number you can message between them. They have your report open and remember the last conversation. They are a coach, not a clinician, and they will tell you when a question is one for a doctor.
Every value is checked against reference limits fixed in advance by our medical director, so the same number is flagged the same way for every man — no one’s file depends on who happened to read it. Anything outside them goes out to a doctor rather than being answered here.
What to expect, conversation by conversation
Straight answers
The questions worth asking us first.
Will this get my partner pregnant?
We cannot promise that, and you should be careful of anyone who does. What we work on is sperm quality and the things behind it. The evidence that antioxidants improve live birth is rated very low certainty, and the best single trial found no benefit. We would rather say that here than in the small print.
Why six months and not three?
Sperm you make today reflect roughly the last seventy-four days. Three months shows whether the direction is right; six shows whether it held. We measure at both, and we do not ask you to keep buying past the point where the numbers stop moving.
I have used steroids or TRT. Should I say so?
Yes, and it changes what we recommend completely. Anything that adds testosterone from outside switches off the signal that makes sperm, and no supplement works around that. Tell us and we will route you to a clinician instead of selling you a protocol that cannot work.
What happens to my data?
Your answers are yours. We do not need an account or a phone number to give you the report, sensitive answers are kept out of the shareable version, and you can delete your record at any time.
What if I already have a semen analysis?
Bring it. If it is recent and complete we will read it rather than repeat it, and start you at the panel that adds something new instead of charging you twice for the same numbers.
