The panels
Test the basics first. Go further 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.
Scored before any lab work

How a result is read
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.
How certain we are
What we can show you, and how sure anyone is about it.
Every claim on this site sits somewhere on a scale from well established to genuinely uncertain. This page says which is which, in the same words we would use with a clinician.
We will say this plainly and build a protocol on it.
We will act on it and measure whether it worked for you.
We will tell you it is not settled rather than imply a result.
Where zinc, B12, folate or vitamin D are genuinely low, correcting them improves sperm parameters in repeated trials. This is the least controversial thing we do.
Raised scrotal temperature from long rides, hot baths and laptops is consistently associated with worse motility and DNA integrity, and the effect reverses when the heat is removed.
Count, motility and DNA fragmentation improve in most trials, but the size of the effect varies a lot between studies and between men.
Losing visceral weight raises testosterone and lowers inflammation. The link to sperm parameters is real but slower and less direct.
Short sleep and chronic stress suppress the brain-to-testis signal. Well described physiologically; fewer trials measure sperm outcomes directly.
The evidence that antioxidant supplements increase live birth is rated very low certainty, and the largest single trial found no benefit. We do not claim this, at any dose.
Ratings follow the same logic as a GRADE assessment: consistency, effect size and how directly the outcome was measured.
- WHO laboratory manual for the examination and processing of human semen, sixth edition (2021) — every reference range we print.
- Cochrane review of antioxidants for male subfertility — the source of the very low certainty rating on live birth.
- Standard Indian laboratory ranges for vitamin D, B12, ferritin, HbA1c and lipids, as reported by the partner lab that runs your sample.
Where your reporting lab uses a different range, that range takes precedence over ours. Nothing on this page is a diagnosis, and none of it replaces a consultation with a clinician.
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.
