About This Chapter
Male Reproductive System - Chapter Summary
The short video lessons in this chapter guide you through the structures and functions of the male reproductive system. You'll study diagrams of internal and external anatomy in addition to reviewing the development and path of sperm within the system. After finishing all of the lessons, you should be able to:
- Identify the male reproductive system's anatomical parts
- Describe the functions of male accessory glands
- Explain the structure and function of the testes
- Understand the sperm's path from the testes to the urethral orifice
- Recognize the purpose of the HPG axis
To help you retain what you've learned or reviewed about the male reproductive system, we provide multiple tools. Lessons come with transcripts that often have links to other lessons containing additional information about important terms. Developed by professional instructors, our videos are usually under 10 minutes and are packed with simplified explanations, graphics and examples to make complex concepts easier to understand. Once you've studied, take the multiple-choice lesson quizzes to test your comprehension of the chapter's topics.
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.
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).
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.
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.
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.
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.
