The vas deferens can be separated visually into t he anteri2 o r medial and posterior segment. The testes are composed of multi2convoluted anterior and posterior collecting t ubules bearing numerous spermatogenic acini. Stages of spermatocyte develop ment wit hin t he acini vary t hroughout t he testis ; however spermatogenesis wit hin each acinus is usually synchronous. The main function of collecting tubules is to transport the spermatids to t he vas deferens. Spermiogenesis continues as t he spermatop hores progress through the vas deferens until sperm maturity is reached. The broad cords of cells lie outside the out circular muscular layers of the terminal vas deferens may be the androgenic gland of T. orientalis.
