Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: The Male Reproductive System

Level#1: The male reproductive system has two jobs. It must first make sperm cells. Sperm cells are male reproductive cells. The male reproductive system also delivers sperm to the female reproductive system. Sperm cells are made in organs called testes. The testes are in a sack of skin called the scrotum. To stay alive, sperm must be kept cooler than other parts of the body. The scrotum is outside the body so it keeps the sperm cool.

1. Where is the scrotum and why is it where it is?

2. Why are sperm kept in the scrotum?

3. What is the job of the testes and where are they found?

Level#2: The male reproductive system has two jobs. It must first make sperm cells. Sperm cells are male reproductive cells. The male reproductive system also delivers sperm to the female reproductive system. Sperm cells are made in organs called testes. The testes are in a sack of skin called the scrotum. To stay alive, sperm must be kept cooler than other parts of the body. The scrotum is outside the body so it keeps the sperm cool. Sperm travel from the testes through thin tubes called sperm ducts. These ducts carry the sperm to the urethra. As the sperm move down the sperm ducts and urethra, three glands add fluids to it. The mixture of sperm and fluid is called semen. The penis delivers the sperm to the female reproductive system.

1. What do sperm travel through when it leaves the testes?

2. What is the mixture of sperm and fluid called?

3. What is the job of the penis?

The male sex hormone is testosterone. Testosterone causes facial hair and body hair to grow. It causes boys' bodies to become more muscular. Testosterone also causes boys' voices to become lower.

1. Explain the path and process that sperm takes from the testes to the female reproductive system.

2. Explain when a boy's reproductive organs begin to mature. 

3. Explain how the male sex hormone testosterone changes a boy's body.
