This paper describes a testicular tubules evaluation using ultrasonic array probe. In this system, we evaluate a diameter of testicular tubules for azoospermia patients. We employ an ultrasonic array probe. We employ cumulative relative frequency of amplitude values as the evaluation index. In the experiment, we employ large and small nylon lines as the good and bad testicular tubules. Amplitude of large nylon line echo is larger than that of small nylon line echo. For the evaluation, we calculate cumulative relative frequency amplitude of acquisition data. Fuzzy if-then rules are made by the cumulative relative frequency of large and small lines. We evaluate a rete of large lines among all lines by using the fuzzy MIN-MAX center-of-gravity method. In this experiment, the proposed method successfully evaluated the rate of the large lines.
