What this tool is for

Male fertility is shaped by a mix of everyday habits and underlying health factors, and small changes can make a real difference to sperm quality over a few months. This checker helps you spot which of those factors might be working against you, so you know where to focus first.

It is not a medical test and it will not measure your sperm count. What it will do is give you a clearer picture of the lifestyle and health areas that are worth looking at, and flag anything that might be worth raising with a GP or fertility clinic.

Who it is for

It is aimed at men who are trying to conceive, or thinking about trying in the next year or so, and want to understand what they can do to improve their chances. It is also useful if you and your partner have been trying for a while without success and you want to rule out or address factors on the male side before going further with testing.

You do not need a diagnosis or any prior test results to use it. If you are curious about how your weight, drinking, smoking, exercise, stress levels, or heat exposure at work might be affecting fertility, this is a sensible starting point.

How it works

You answer a short set of questions about your lifestyle, general health, and any relevant medical history. The tool then gives you a plain English summary pointing out which habits are likely to be helping, which could be holding sperm health back, and what practical steps tend to improve things. It takes a few minutes, your answers are not saved, and nothing is shared with anyone. If the results suggest you should speak to a doctor, the summary will say so clearly, so you can take the next step with a better idea of what to ask.
