Figure 1: (a) Morphometric analysis of the seminiferous tubules and Leydig cells in fetal testis. The diameter of seminiferous tubules was measured using the program at least five times for each specimen and was determined by the contour of the epithelium. HE ×400. (b) Morphometric analysis of the seminiferous tubules and Leydig cells in fetal testis. To quantify the number of seminiferous tubules we used the Image J Test grid software to determine the volumetric density (Vv). HE ×400.
