Correctly match the numbers listed on the left to the chronological pathway of Sperm (from formation to ejaculation) in ascending order. 1. Sperm are produced in the Penis. 2. Arousal/Erection: Blood rushes to the erectile tissue and causes the penis to stand up and become hard. 3. Sperm move to the Epididymis to mature. 4. Seminal Vesicle adds a nutrient-rich fluid, high in fructose, to the sperm, making a mixture called semen. 5. Prostate Gland contributes more fluid to the semen. 6. Cowper's Gland secretes a basic fluid that neutralizes the acidic urethra before the semen arrives (this is called the pre-ejaculate). 7. Sperm move to the Vas Deferens to begin traveling through the male body (The Sperm Highway).

REFLECTION ABOUT THIS LESSON PHYSICAL or PHYSIOLOGICAL CHANGES AND THEIR IMPLICATIONS ●You started to experience various body changes when you were around 13 years old, which is the onset of adolescence for most children. ●Girls start their growth spur earlier than boys, but boys eventually grow taller than girls. ●Also, boys muscle grows faster The boys’ testes or gonads rapidly grow bigger for a year during early pubescence. Similarly, shortly after the rapid change in the testes, the penis also grows markedly. Boys come to know that there is production and release of sperm, spermarche, when they experience nocturnal emissions or wet dreams. This is an indication that their male reproductive organs have become mature in function and that they are already capable of reproduction.
