In 1973, the average man had a sperm concentration of 99 million/mL. In 2011, it was 47 million/mL. That's a 50% drop in 40 years, and the trend isn't slowing down.

Most guys don't know this. The media doesn't cover it. Doctors don't screen for it unless you're actively trying to conceive. By the time it becomes obvious, you're already making decisions under pressure.

The causes are everywhere: microplastics in your water, laptops on your lap, chronic stress, delayed fatherhood, environmental toxins, heat exposure. Modern life is quietly eroding male fertility, and the default response has been to wait until it's a crisis and then throw expensive fertility treatments at it.

We thought there should be a better option. Test early. Preserve if needed. Keep options open before biology forces your hand.

Paternal exists because fertility preservation and testing shouldn't be a last resort. It should be a planning tool, available before the conversation gets stressful and the timeline gets tight.

Think of it this way: you can't control the fact that sperm counts are declining. But you can control whether it affects your future.
