Its all about science

1. Lesson 4.1 The Male Reproductive System

2. describe the parts of the male reproductive system and their functions. 1 A t the end of this lesson, you should be able to:

3. The reproductive system is in charge of the production of new organisms.

4. The Reproductive System Gonads or reproductive glands produce sex cells. The main function of the male reproductive system is to produce sperm cells. The union of male and female sex cells is a process known as fertilization.

5. The Male Reproductive System The testicles or testes (sing. testis) are the major organs of the male reproductive system. These produce sperm cells and release testosterone. Parts of a the male reproductive system

6. The Male Reproductive System The epididymis is a temporary storage of the sperm cells after production. Sperm travel to the vas deferens when they mature. Vasectomy is a procedure to block the vas deferens. Vasectomy

7. Accessory Glands The accessory glands are responsible for the discharge of the fluid part of the semen. The prostate gland is in charge of producing fluids that serve to nourish sperm. Prostate gland

8. Accessory Glands The Cowper’s glands or bulbourethral glands produce fluids that protect the sperm during ejaculation. The seminal vesicles produce the majority of the fluids in semen. Bulbourethral gland and seminal vesicles

9. Male Reproductive Parts The urethra carries urine and semen to the outside of the body. The penis delivers sperm to the female. Side view of the male reproductive system.

10. The gonads of the male reproductive system are testes, that produce the sperm cells and testosterone. 1 After the sperm cells mature, they travel to the epididymis, the vas deferens, then the urethra. 2 Semen is a mixture of sperm and fluids from the accessory glands. These fluids will help nourish and help transport the sperm for reproduction. 3

11. Encircle the correct word. (Reproduction, Fertilization) is the process of producing offspring. The (union, separation) of the sex cells or (gametes, gonads) is called fertilization. The main function of the male reproductive system is to produce (sperm cells, egg cells). (Reproduction, Circumcision) is usually done to lower the risk of infections and other diseases in males. The (testes, testosterone) are the major organs of the male reproductive system.

12. Can sperm cells perform their functions without seminal fluid?
