Hello! This site was created to help calculate the angle of the penis’s curvature during erection (erectile deformity) correctly, as well as to calculate the difference between the convex (longer) and concave (shorter) surfaces of the penis. This information will help your doctor to choose the right method of treatment, as well as to monitor the effectiveness of treatment.

# The calculation of the angle of curvature and the difference between the convex and concave surfaces of the penis

### STEP 1

During the erection, measure the circumference of the penis before curvature and immediately after the curvature - fig. 1.

These distances should be measured with a soft (tailoring) ruler in mm. Record or memorize the results.

### STEP 2

Take an erection photo of the penis. IMPORTANT: the camera lens must be strictly at an angle of 90 degrees to the plane of curvature. Try to get the penis in the photo turned out clear and contrast.

Example 1. If there is a curvature of the penis up (dorsal) or down (ventral), you need to take pictures from the side - fig. 2 and fig. 3. The most convenient way is the photo to be made by your contact person (sexual partner, doctor, etc.)

Example 2. If there is a curvature of the penis to the side (left or right), it is most convenient to take pictures yourself from top to bottom - fig. 4 and fig. 5.

### STEP 3

Now you need to measure the angle of the curvature of the penis (angle ß °).

This angle you can measure yourself with a protractor. To do this, it is necessary to postpone the longitudinal axis (line) to the area of maximum curvature of the penis and after - fig. 6. The angle ß ° is the angle of deviation or the angle of curvature.

If you use our mobile application (link below - STEP 4), you can also find out the angle of the penis’s curvature.

### If you measured the angle of the curvature yourself:

If you measured the angle of the penis’s curvature on your own, then enter the results below and you will find out the difference between the convex and the concave surfaces of the penis.

L1 - the penis’s circumference to curvature (mm)

L2 - the penis’s circumference after curvature (mm)

ß - the angle of the penis’s curvature (degrees).
