Abstract

The human reproductive system is made up of the primary and secondary organs, which helps to enhances reproduction. The male reproductive system is designed to produce male gametes and convey them to the female reproductive tract through the use of supportive fluids and testosterone synthesis. The paired testis (site of testosterone and sperm generation), scrotum (compartment for testis localisation), epididymis, vas deferens, seminal vesicles, prostate gland, bulbourethral gland, ejaculatory duct, urethra, and penis are the parts of the male reproductive system. The auxiliary organs aid in the maturation and transportation of sperm. Semen is made up of sperm and the secretions of the seminal vesicles, prostate, and bulbourethral glands (the ejaculate). Ejaculate is delivered to the female reproduc¬tive tract by the penis and urethra. The anatomy, embryology and functions of the male reproductive system are discussed in this chapter.

Highlights

  • Reproduction refers to the production of new offspring, known as breeding in animals

  • It includes a set of physiological processes that take place in the female reproductive system with the association of behaviors and anatomical structures that are necessary in order to ensure the birth of the generation of human, domestic, wild, and laboratory vertebrate organisms

  • The primordial germ cells have shifted from their previous extra embryonic position to the gonadal ridges by the six weeks of development in both sexes, Male Reproductive Anatomy where they are surrounded by the sex cords to form a pair of primitive gonads

Summary

Introduction

Reproduction refers to the production of new offspring, known as breeding in animals It includes a set of physiological processes (usually) that take place in the female reproductive system with the association of behaviors and anatomical structures that are necessary in order to ensure the birth of the generation of human, domestic, wild, and laboratory vertebrate organisms. The males’ reproductive system functions mainly in the production, nourishment and temporary storage of male gametes (spermatozoa), which is produced via spermatogenesis It produces androgens and estrogen through steroidogenesis [1] and very importantly, connected to the organ of copulation (penis) which serves to introduce semen containing spermatozoa into the female genital system via mating
