    We'd been trying for 8 months. This showed us in 5 minutes what two doctor visits couldn't tell us. Absolute game-changer

    Why most couples keep guessing for way too long

    When you've been trying with no luck, most people assume it's timing or stress — and keep going for months without ever checking the swimmers. By the time they book a clinic appointment, it's weeks out and the wait is brutal.

    The real issue is usually movement. Sperm have a tail that drives them forward, and when that motion is weak or absent, they can't reach the egg. How well they swim matters more than how many there are.

    The Krebba Swim Check magnifies a single drop 400x so you can see exactly what's happening — before you burn another cycle guessing.

      "I thought it was me — turns out I was fine"

      My wife and I had been trying for almost a year. I did the Swim Check just to see, and they were swimming strong. Changed the whole conversation we had to have next.

      "Worth every penny before a doctor visit"

      We used this before booking a fertility consultation. Came in with actual information instead of just "we've been trying." Our doctor said it was the smartest thing we could've done first.

      "Checked my vasectomy — still holding"

      Two years post-vasectomy and my wife wanted peace of mind. Loaded one drop in, zero swimmers. Exactly what we needed to see. No appointment, no awkward conversation.

      Frequently Asked Questions

      A portable LED microscope that magnifies a semen sample up to 400x so you can see sperm movement, count, and shape in real time using your phone camera — no lab, no clinic, no wait.

      Add one drop of sample to the collection port, power on the LED, and align your phone camera to the observation lens. You'll see your swimmers within seconds. The whole process takes under five minutes.

      Immediately. There's no processing time. The moment you look through the lens, you'll see whether your sperm are moving, how fast, and what they look like.

      Anyone who wants to understand their fertility picture at home — couples trying to conceive, men who've had a vasectomy and want to confirm it's still holding, or anyone who wants a real answer before booking a clinic visit.
