FAQ

To use the the app, rotate your phone to the left or right. The app will now switch to landscape mode. Hold the phone next to one of your testicles with one hand, and position your testicle next to your phone with the other hand. Use your thumb to adjust the orchidometer size with the slider. When your testicle size matches with the orchidometer, read the volume that is displayed.

Go to the settings, click on 'Testicular atrophy' and enable the 'Show indicator' option. If your testicle size matches the orchidometer, read the text that is displayed in the top left. If the indicator displays 'Possible testicular atrophy', your testicular volume is smaller than 12 ml and you may suffer from testicular atrophy. If the indicator displays 'No testicular atrophy', your testicular volume is greater than 12 ml, it is highly unlikely that you are suffering from testicular atrophy. The Orchidometer app does not provide a medical diagnosis and you should always consult a doctor first. This mobile app is intended for informational, educational and research purposes only.

To save a measurement, tap the orchidometer. A sheet will appear with the current volume, date and an option to select the left or right testicle. You can also enter a manual measurement by going to the measurements screen. Click on 'New' in the top right and manually fill in the volume, date and left or right testicle. When your measurement is complete, click on 'Save'.

To delete a single measurement, go to the measurements screen and click on 'All measurements' under 'Options' at the bottom. Find the measurement you want to delete and swipe it to the left. You will now be able to delete the measurement.

When opening the app, click on the chart icon in the top right. You will now see a chart with all your measurements. You can filter on day, week, month and year. If you want to view all measurements in a list, click on 'All measurements' under 'Options' at the bottom.

Click on the settings icon and click on 'Reminders'. First, make sure that 'Allow notifications' is turned on. Decide how frequently you want to receive reminders by setting the frequency to 'hourly', 'daily' or 'weekly'. If you want to receive reminders multiple times per day, set the frequency to 'daily' and select a start and end time, as well as the interval (every 1, 2, 4, 6, 8 or 12 hours). For daily reminders, set the frequency to 'daily' and select the time you want to receive a reminder. If you want weekly reminders, set the frequency to 'weekly' and tap the days of the week you want to receive reminders.

Click on the settings icon and select 'Help'. Click on 'Delete all measurements' and confirm you want to continue by clicking 'Delete'.

Yes, there are several ways to adjust the orchidometer. Use a drag gesture to adjust the height of the orchidometer and make it more or less round. To adjust the width, use the slider at the bottom. To rotate the orchidometer, use a rotation gesture.

There are currently four orchidometer types: Default, Anatomical, Beads and Augmented Reality. The default orchidometer is a simple ellipse that can be scaled using a slider. The anatomical orchidometer is similar, but shows a testicle instead of an ellipse. The beads orchidometer type resembles a real orchidometer and contains several beads that are ordered from small to large. You can slide through these beads and find the bead that matches your own testicle's size. Augmented Reality is still an experimental feature and will be improved continuously. It only works well on newer iPhone models with LiDAR support. It allows you to place the orchidometer in 3D space.

The volume of a testicle can be estimated with the Ellipsoid formula (L x W x H x 0.52) or with the empirical formula of Lambert (L x W x H x 0.71). Lambert's formula generally provides better accuracy in clinical practice. In practice, measurements made with Lambert's formula will result in slightly larger volumes.
