Analytic morphometry in diagnostic pathology: upper degree polynomials and Fourier harmonic analysis in infertility

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.
