1. Lesson 10.1 Male Reproductive System

2. Describe the parts and functions of the human reproductive system. At the end of this lesson, the given enabling competency should be met by the students.

3. Discuss the parts of male reproductive system and their respective functions, and Discuss the functions of male reproductive system that differentiate it from female reproductive system.

4. While the female reproductive system is designed not only to reproduce gametes and produce female hormones, it also carries and nourishes an offspring. The male reproductive organs serve a more distinct purpose compared with that of a female.

5. The reproductive duty of a male is to produce gametes and deliver them to the female reproductive tract. The organs themselves differ in structure and appearance.

6. What are the components and functions of the male reproductive system? How do they differ from that of the female reproductive system?

7. Components: Testes The male reproductive system has two testes . Their function is to produce male sex cells called sperm cells . The sperm cells develop inside the seminiferous tubules . Seminiferous tubule

8. Components: Scrotum The scrotum is a bag of skin that contains the testes. It is a reproductive structure that is located under the penis. The scrotum

9. The scrotum is responsible for protecting the testes. It helps with the thermoregulation of the testicles. It keeps the temperature of the testis several degrees below the average body temperature, which is an essential factor for sperm production.

10. What is the role of seminiferous tubules and what is the role of Leydig cells? The chief function of the seminiferous tubules is the production and transportation of sperm cells. The main function of the leydig cells is to secrete androgens such as testosterone.

11. Components: Scrotum Within the scrotum are muscles known as the dartos and cremaster muscles . These play important roles in maintaining the temperature of the scrotum. The scrotum

12. Components: Epididymis Mature sperm cells are later on stored in a tube beside the testes known as the epididymis. The epididymis is a duct-like organ that connects the testis to the vas deferens  The sperm cells are stored until they are released from the body through a process known as ejaculation . The male reproductive system

13. SEMINAL VESICLES- are pair of lumpy exocrine glands located posterior to the urinary bladder and anterior to the rectum. main function of the seminal vesicles is to produce a fluid that is high in fructose, a sugar that provides nutrients for sperm cells, as well as other proteins, enzymes, and mucus. This fluid is a major component of semen, and it accounts for about 50%–80% of semen volume.

14. Components: During ejaculation, the sperm cells move from the epididymis to a tube called the vas deferens , then into another tube known as the urethra , and finally out of the body. The male reproductive system

15. The vas deferens transports mature sperm to the urethra in preparation for ejaculation . Urethra - this tube allows urine to pass outside the body.

16. Contains smooth muscle tissue that can constrict to prevent the flow of urine or semen. It produces a large portion of the fluid that makes up the semen, this fluid is milky white in color and contains enzymes, proteins and other chemicals to support and protect the sperm during ejaculation. PROSTATE

17. The function of the penis is to deliver semen into vagina during sexual intercourse. SEMEN Is the fluid produced by males for sexual reproduction. SPERM CELLS  main function is to fertilize an egg during reproduction. PENIS

18. The process of producing sperm that takes place in the testes and epididymis of adult males. SPERMATOGENESIS

19. The process by which a sperm combines with an oocyte (egg cell) to produce a fertilized zygote. FERTILIZATION

20. The sperm attaches and binds. Penetrates the outer corona radiata and zona pellucida,when the sperm fuses 4. The eggs membrane , genetic material is released inside the egg. Fertilization occurs when the sperms genetic material eventually combines with eggs genetic material. STEPS IN FERTILIZATION

21. Vasectomy Vasectomy is a method of birth control that deals with cutting or blocking the tube of vas deferens. This prevents sperm cells from being transported out of the body. Vasectomy

22. Components: Penis The penis is the external part of the male reproductive system. It is a tube-shaped organ that contains the urethra, which allows it to pass the urine and semen out of the body. The male reproductive system

23. Circumcision Many cultures practice a medical process known as circumcision . This process involves the partial or complete removal of the prepuce to expose the glans penis. Circumcision

24. Accessory Glands The male reproductive system also has a series of organs known as the accessory glands . These glands secrete substances that aid in the nourishment of sperm cells and contribute to higher chances of fertilization. Examples of these are the seminal glands , bulbourethral glands , and the prostate glands .

25. The Male Reproductive System The production, development, and maturation of sperm cells occur in the male reproductive system. The primary male sex hormone is known as testosterone , and it is produced by the testes. Another function of the male reproductive system is to safely and properly deposit the sperm cells into the female reproductive tract .

26. The male reproductive system is composed of the testes, scrotum, epididymis, vas deferens, urethra, penis, sperm ducts, and accessory glands. The gonads of the male reproductive system are the testes . The male reproductive system consists of two testes.

27. Write the word true if the given statement is correct or false if otherwise. Males have a significant amount of estrogen. The exit points for urine and sperm are different. The sperm ducts include the seminal vesicles and the vas deferens. Prostate fluid neutralizes acidity. The scrotum is an internal organ.

28. The male reproductive system is specialized for the production of sperm cells and their deposition into the female reproductive tract. The functions of the male reproductive system include the production, development, and maturation of sperm cells that occur in the male reproductive system. The type of gametogenesis that occurs in male organisms is known as spermatogenesis .
