Check if your testicular volume is normal with the Orchidometer app. Find out if your volume is associated with Klinefelter syndrome or testicular atrophy.
Measure testicular volume with the Orchidometer for iPhone. The orchidometer is highly customizable and automatically adjusts itself to your screen size. It can be used to estimate Tanner stage, age and pubertal development.
Measurements can be saved and visualised for both testicles. The Orchidometer app can be used to track the testicle’s volume while on TRT or when you suffer from testicular atrophy, low testosterone or infertility. The app can also be used as an indication for Klinefelter syndrome.
Whether you're an endocrinologist, pediatrician or just interested in measuring testicular volume: this app will replace your classic orchidometer.
