Question
Chapter 27, Problem 11TYR
Summary Introduction
Introduction:
Mesonephric duct is a primitive type of excretory system developed during embryonic stages. It is similar to that of excretory tubules present in the lower invertebrates like flat worms. In the developing embryo, it is influenced by the androgenic hormones like testosterone, and it is modified into the male reproductive system of vas deferens. Mesonephric duct acts as a sex differentiation system based on the androgen hormone testosterone’s presence and absence.
