A semen analysis and a full blood panel. At home.
of couples who struggle have a male factor involved.
And men are still tested last.
A semen analysis counts how many, how well they move, and how many are shaped normally. The first of those looks like this.
Illustration, not a micrograph. Densities are indicative of the WHO 6th edition lower reference limit of 16 million per millilitre.
That is the population. Your own number is the one worth knowing.
One full cycle of sperm production. Change the inputs now, see it in three months.
A kit arrives. No waiting room, no clipboard.
Switch on what you want. We'll tell you which tests aren't worth your money.
Yours and hers, together. On video.
And when you need a urologist, not a supplement.
Not a stack of pills and a printout.
Included. You don't have to ask twice.
Ranked by your results. Every line graded.
Unglamorous, and the strongest evidence there is.
Cheap to avoid, evidence still thin.
Plus "detox" protocols and miracle blends. Skip all of it.
Either the numbers moved or they didn't. Both are useful.
Proof, not vibes.
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.

In couples who don't conceive, a male factor is involved in roughly half of cases, sometimes as the only cause and often alongside a female factor. It's the most under-tested variable in the process and the cheapest to check. Grade: solid.
Spermatogenesis takes about 74 days, plus roughly two weeks of maturation in transit. What you change today shows up in a sample about three months from now. Slow enough to need patience, fast enough to prove something. Grade: solid.
The sixth-edition manual puts the lower reference limit at 16 million/mL concentration, 42% total motility and 4% normal forms. These are the fifth percentile of men whose partners conceived within a year: a floor, not a pass mark. Below one is a reason to look closer; above them all guarantees nothing.

In more than 78,000 men followed for up to fifty years, those with the highest total motile sperm counts lived around 2.7 years longer than those with the lowest. That's an association, not a promise. Healthier men have better sperm and also live longer.

A meta-regression of 223 studies covering 57,000 men across six continents found sperm concentration fell 51.6% between 1973 and 2018, from 101.2 to 49.0 million per millilitre. Total sperm count fell 62.3%. The decline is steepening: 1.2% a year since 1973, and 2.6% a year since 2000.

It is a population average, so it says nothing about you specifically. That is what the test is for.
Samples vary a lot between days. Illness, a fever, a rough stretch of sleep or drinking all show up. A single low reading usually warrants a repeat test and a doctor's read. These are screening tests: they show where you stand, they don't diagnose infertility.
It works better that way, because one doctor reading both sets of results catches things separate appointments miss. But plenty of men start on their own, and there's a full page for her when she's ready.
