M ALE R EPRODUCTIVE S YSTEM The internal structures of the male reproductive system play a role in the delivery of sperm. Internal Male Reproductive Organs Although sperm are produced in the testes, which are suspended outside the body, they must travel through several structures inside the body before they are released. These structures include the vas deferens, the urethra, the seminal vesicles, the prostate gland, and Cowper’s glands. Figure 18.2 shows the path taken by sperm cells from the testes until they are released from the body. 470 Chapter 18 Endocrine and Reproductive Systems Seminal Vesicle As sperm move through the vas deferens, they are combined with a nourishing fluid produced by the seminal vesicles. vas deferens Prostate Gland and Cowper’s Glands Secretions from the prostate gland and Cowper’s glands combine with the sperm-containing fluid to form semen. penis scrotum bladder Urethra The urethra is the passageway through which both semen and urine leave the male body.

Monthly TSE Reminder Card It’s important for males to do a testicular self-exam (TSE) every month. However, not all males are accustomed to performing it. In this activity you will create a reminder card for yourself or the males in your family. paper colored pens lamination supplies (optional) 1. Cut the paper into a wallet-sized card. 2. On one side of the card, write out the steps in performing a TSE (see page 472). 3. On the other side of the card, create a message that will remind and persuade you or males in your family to do a monthly exam. The exam could be scheduled for the same time each month, such as the first day of every month. 4. Laminate the card so that it will last. Keep the reminder card in a location where you (or males in your family) will see it often. Because the best time to examine yourself is after a warm bath or shower, consider placing the card in the bathroom.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
