Morphometric studies on rat epididymis in the course of postnatal development (computerised image analysis).

The studies were aimed at histological and morphometric analysis of postnatal development of epididymis in rats aged 1, 5, 10, 20, 28, 35, 45 and 59 days. Diameter of ductuli efferentes and of ductus epididymidis, height of epithelium, section area fractions occupied by the epithelium and by the sublayer were estimated (using MultiScan software) and serum testosterone levels were measured. The results documented a stepwise development of the epididymis, in three distinguishable stages.
