Learning outcomes

After studying all of the resources available, your knowledge of the “Male Reproductive System” should include the following:

• Recognise and name the structures of the male reproductive system.
• Understand the gross structure of the testis.
• Identify all of the cells of the seminiferous epithelium.
• Distinguish between spermatogenesis and spermiogenesis and describe the progression of sperm through the complete process of spermatogenesis.
• Identify Sertoli cells and describe their main functions.
• Identify Leydig cells (interstitial cells of the testis) and describe their main functions.
• Understand the hormonal control of spermatogenesis.
• Identify the ducts involved in the passage of sperm from the testes to the penis, and describe what role each plays in the maturation of sperm.
• Identify the accessory sex glands and know their role in nourishing and protecting the sperm after ejaculation.
• Distinguish between sperm and semen, and know the components of semen.
• Understand the structure of the penis and how blood flow causes erection.
