Male fertility, measured and explained.

Seminal pairs laboratory semen analysis with the habits that shape it — and tells you what was measured, what it means, and what the evidence actually supports.

Seminal does not diagnose and is not a substitute for laboratory testing or clinical advice.

Reflects logged behaviour only — never your semen parameters.

Measure. Explain. Improve.

Evidence, labelled

We tell you how sure the science is.

Every claim in Seminal names its measured outcome, its study design, and whether the result is causal or observational. An association is never presented as your personal effect.
