- 1. Ensure the _______ of the specie What is the major function of the reproductive system?
- 2. r______ all biological processes in the body from conception through adulthood and into old age What is the major function of the endocrine system?
- 3. ACTIVITY: THE CONDUCTOR When you listen to a symphony, many different instruments must play the right notes at the right times to produce the beautiful music we hear. For all these separate elements to work together, a conductor tells each instrument what, when, and how to play.
- 4. • pound the table Clap your hands
- 8. Gonadotrophins • Gonadotrophs, cells that constitute about 10 percent of the pituitary gland, secrete two primary gonadotropins: luteinizi ng hormone (LH) and follicle-stimulating hormone (FSH).
- 11. • Another type of gonadotropin found in women is human chorionic gonadotropin (HCG), which is produced by the placenta during pregnancy. The detection of HCG forms the basis of pregnancy tests.
- 13. Physical effects of Teen Hormones Androgen and Testosterone
- 14. Testosterone Testosterone is the major sex hormone in males and plays a number of important roles, such as: • The deepening of the voice during puberty • The appearance of facial and pubic hair starting at puberty; later in life, it may play a role in balding • Muscle size and strength • Bone growth and strength • Sex drive (libido) • Sperm production • Maintenance of accessory glands and organs of male reproductive system
- 15. Negative Feedback Loop in males
- 16. Testosterone in Females • Testosterone is produced in the ovaries and adrenal gland. These hormones are thought to have important effects on: • Ovarian function • Bone strength • Sexual behavior, including normal libido
- 17. Use of anabolic steroids and testosterone Problems associated with abnormally high testosterone levels in men include: •impotence •Acne •Fluid retention with swelling of the legs and feet •Weight gain, perhaps related in part to increased appetite •Increased muscle mass •Stunted growth in adolescents •Uncharacteristically aggressive behavior (although not well studied or clearly proven)
- 18. High Testosterone level in Women Polycystic ovary syndrome (PCOS) One treatment available for many of these problems is spironolactone, a diuretic (water pill) that blocks the action of male sex hormones.
- 19. Physical effects of Teen Hormones Estrogen and Progesterone

Editor's Notes
- Let us review some body systems. Ensure the survival of the specie. Why do you think did the creator added this feature to us?
- To regulate hormones which acts as messengers to other organs and systems of the body to signal them to complete a certain task or process. ... This includes the reproductive
- To understand more about the role of endocrine in reproductive system. I have here an activity. If you think about any complex process, it usually requires someone to manage all the parts. And this is what the endocrine system does for our body including the reproductive system. When you listen to a symphony, many different instruments must play the right notes at the right time to produce the beautiful music we hear. For all these separate elements to work together, a conductor tells each instrument what, when, and how to play.
- So in this activity, I will be the conductor and whenever you see a circle just pound the table, and if it’s a square, clap your hands.
- Can you guess the song that we will play?
- Wow. That was lovely. From this activity, we can see the importance of timing and instruction from a conductor to create a beautiful music.
- The electronic store manager was bullied for years because he was smaller and weaker than other children and still had no facial hair and a high voice until his late teens.
- Gonadotroph cells (indicated by arrows) constitute about 10 percent of the pituitary gland and secrete hormones called gonadotropins, which include luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
- The androgen and testosterone has a lot of effects on the secondary male sex characteristics as evident in this photo.
- Signals sent from the brain to the pituitary gland at the base of the brain control the production of testosterone in men. The pituitary gland then relays signals to the testes to produce testosterone. A negative feedback loop, also known as an inhibitory loop, is a type of self-regulating system. When testosterone levels rise too high, the brain sends signals to the pituitary to reduce production.
- If you thought testosterone was only important in men, you'd be mistaken.
- most of what we know about abnormally high testosterone levels in men comes from athletes who use anabolic steroids, testosterone or related hormones to increase muscle mass and athletic performance.
- The ovaries of women with PCOS contain multiple cysts. Symptoms include irregular periods, reduced fertility, excess or coarse hair on the face, extremities, trunk and pubic area, male-pattern baldness, darkened, thick skin, weight gain, depression and anxiety. One treatment available for many of these problems is spironolactone, a diuretic (water pill) that blocks the action of male sex hormones. Women with high testosterone levels, due to either disease or drug use, may experience a decrease in breast size and deepening of the voice, in addition to many of the problems men may have.
- Oestrogen and progesterone are two female sex hormones secreted by ovaries and adrenal glands. Oestrogen is the main female sex hormone, which is responsible for the development of secondary female sex characteristics. On the other hand, progesterone plays a big role during the pregnancy. It helps to sustain the pregnancy. Moreover, it also prepares the uterus for implantation and maintains the elasticity of it. This is the difference between oestrogen and progesterone.
