The Histology Guide

Introduction

The main functions of the male reproductive system, are to produce spermatozoa, androgens (sex hormones - principally testosterone) and to facilitate fertilisation, by introducing spermatozoa into the femal genital tract (copulation). The male reproductive system includes the testis, genital ducts, accessory sex glands and penis. After following this topic, you should know the structure and function of these structures.
