Abstract

The shape of the seminiferous tubuli in maturation arrest is investigated by harmonic Fourier analysis and upper degree polynomials. The epithelial boundary line of the lumen is considered as a curve in a reference system after the points of the curve have been defined by coordinates: an automatic procedure (TV-camera interfaced with a computer) is utilized and the software expresses the profile as a Kth-order equation and submits real and calculated periodic function to Fourier analysis. Fourier analysis is very useful in shape trend investigations and its modifications are not dependent on perpendicular cross-sections. The method helps us to distinguish different types of maturation arrest.
