The mucus secreted by the uterine cervix plays essential roles in the process of human reproduction. The rheological properties of the cervical mucus vary according to the ovarian cycle. The purpose of this study is to develop measuring methods for mechanical properties of cervical mucus, which are applicable to medical test. Two new apparatuses were developed. One is to measure the velocity and attenuation of ultrasonic wave (5MHz) in a syringe employed for collecting the specimen. The other is for rapid measurement of viscoelasticity over a frequency of 1-300Hz based on the fast Fourier transform of the response (displacement) to the applied pseudo-random force, a force consisting of sinusoidally varying components with various frequencies. Examples of measurements with these apparatuses and the biomechanical spectrometer reported previously are shown for bovine cervical mucus, human cervical mucus, and human synovial fluid. Ultrasonic sound velocity and attenuation of bovine cervical mucus were 1437m/sec and 0.97dB, respectively. The bovine cervical mucus was more elastic and less viscous than human cervical mucus.
