Testicle Model This life-size testicle model offers an extremely natural feel. By using SKINlike™ (dermatologically tested), 3B's new high-quality silicon, learning and practicing self-examinations of the testicles becomes even more realistic. The scrotum contains two movable testicles, the epididymi and the spermatic cords for palpation. Two pathological findings can be felt in the left testicle. The front of the model also includes a replica of the beginning of the penis. Supplied with detailed instructions for self-examination and a carrying bag.
