Erections
Firmness, morning erections and control. Erection quality is often the earliest visible sign of blood-vessel health.

What the check covers
Desire and energy
Sex drive and daytime energy, which move with sleep, stress, relationships and hormones.
Semen and fertility
Changes in volume and the heat exposure that sperm production is sensitive to.
Everyday habits
Sleep, movement, alcohol, nicotine and weight: the levers with the strongest research behind them.
Stress and mind
Stress load and performance worry, which can undo good physical health in the moment.
Questions about the check
Is this a medical test?
No. It is a structured self-assessment that points you towards the habits and signals worth attention. It cannot diagnose anything, and a good score does not replace a check-up if something feels wrong.
Are my answers stored or sent anywhere?
No. The check runs entirely in your browser. If you choose, your last score is saved on this device only so you can compare next time; clearing your browser data removes it.
How is the score worked out?
Each answer scores 0 to 3 points in one of five areas: erections, desire and energy, semen and fertility, everyday habits, and stress and mind. Each area becomes a percentage, and your overall score is the average of the five.
What should I do with a low score?
Start with the levers listed under your results: they are ordered by where you lost the most points. If erection problems, a drop in drive or trouble conceiving last more than a few months, book a GP appointment and mention them directly.
How often should I retake it?
Every two to three months is enough. Sperm take roughly ten weeks to develop, so changes in semen and fertility habits take about that long to show up.
