Ch 22: GRE Biology: Male Reproductive Structures

About This Chapter

Our engaging video lessons provide an easy, convenient way to refresh your knowledge of male reproductive structures. Take the quizzes that follow each lesson to gauge your understanding of the content.

GRE Biology: Male Reproductive Structures - Chapter Summary

Use our video lessons to review the anatomy and functions of male reproductive structures. The lessons cover what you need to know for related questions on the GRE Biology Test, including:

  • Accessory gland functions
  • Testicular anatomy
  • External and internal anatomy
  • HPG Axis
  • Sperm's path from the testes to the urethral orifice

The lessons in this chapter are less than 10 minutes long and are taught by experts in the field of biology. You can watch the videos as many times as you would like to be sure you understand the concepts discussed by the instructors. We also provide transcripts of the lessons to give you another resource to learn the materials. A chapter exam offers an additional tool for studying male reproductive structures.

GRE Biology Objectives

The GRE Biology Test is a 190 multiple-choice question test offered to graduate school applicants to highlight the breadth of their knowledge of biology. The test is organized into three main subject areas, each of which carry equal weight. They are: cellular and molecular biology, organismal biology, and ecology and evolution. Questions on animal reproduction and development, including male reproductive structures, are asked under the organismal biology subject area and account for 6% of all test questions.

Each test question provides five answers choices. The test is offered three times per year in September, October and April in a paper format.

Male Reproductive System: Functions, Organs & Anatomy

1. Male Reproductive System: Functions, Organs & Anatomy

The male reproductive system includes various structures and pathways to transport sperm. Learn about the anatomy, organs, and functions of the male reproductive system.

Male Reproductive System: Accessory Gland Functions

2. Male Reproductive System: Accessory Gland Functions

Ninety-five percent of semen is made from secretions from the accessory glands. Learn about the male reproductive system, the difference between sperm and semen, and the functions of the accessory glands (seminal vesicles, prostate, & bulbourethral).

Testicular Anatomy: Structure, Terms & Diagrams

3. Testicular Anatomy: Structure, Terms & Diagrams

The testes are the male reproductive organs where spermatogenesis and hormone production occur. Learn about testicular anatomy, the functions of the testes, what takes place in between the seminiferous tubules, and the importance of the testes in human reproduction.

Male Reproductive System: External Anatomy

4. Male Reproductive System: External Anatomy

The external anatomy of the male reproductive system includes the penis, scrotum, and testes, which are designed to work in unison to impregnate females of the same species. Take a closer look at the structures and functions of the human penis, scrotum, and testes.

Sperm's Journey from the Testes to Urethral Orifice

5. Sperm's Journey from the Testes to Urethral Orifice

Spermatozoa are produced in the testes, beginning a journey that plays an important role in reproduction. Explore the detailed path sperm takes from the testes to the urethral orifice with the end goal of passing on its DNA by fertilizing a female egg.

The HPG Axis: Hormones of Male Reproduction

6. The HPG Axis: Hormones of Male Reproduction

Male reproduction is controlled by hormones. Learn about this process, including how males change as they experience puberty. Explore the HPG Axis, the hypothalamus, the anterior pituitary, LH, FSH, gonads, testosterone, and inhibin.
