The possibility that thick seminiferous tubules (300μm in diameter) include the sperm is higher than that of thin seminiferous tubules (100μm in diameter). Ultrasonic measurements usually employ Pulse-Echo method. The method calculates an object depth by detecting a received wave time. This spatial resolution of the method is determined by a wavelength of ultrasonic. (1) Our study group proposed a characteristic between ultrasonic reflection wave frequency and line thickness. Our research indicated that a frequency of thick lines (three soft matters) is lower than it of a thin line. This relation does not hold for metals. (2) An ultrasonic imaging technique is provided for seminiferous tubules in a testicle. By using the above characteristic, we make a cross-section image that indicates a distribution of seminiferous tubules beyond the wavelength limit. This image clearly locates the thick or thin lines.
