What’s Going on Down There? By Karen Gravelle with Nick and Chava Castro

Dear teenager,

Do you feel embarrassed to ask question regarding your changer in body such as voice, pimple, appearance hair on body and so on? If yes, I do recommend you to read this book titled “What’s going on down there?” where you will find the answer for your curious. After reading this book, I do learn something about puberty of teenager although my puberty had been passed.

This book has contained some picture that made you easily to understand such as the function of organs. Besides that, Robert Leighton is an illustrator for the book that will not make you feel bore when reading this book.

Below are the exact that I copy from the book that for my knowledge:-

Sperm go from testicles where they are made, to the epididymis where they mature or grow up. Once they have matured, they travel through another tube, the vas deferens to a sort of holding tank called the ampulla where they are stored. Luckily the vas deferens has muscles to help push the sperm along. At this point in their lives, sperm are not very energetic swimmers and couldn’t get from the epididymis to the ampulla on their own.

Near the ampulla are two other organs, the seminal vesicles and the prostate gland. They provide fluids that give the sperm energy and help them travel through the penis. At the ampulla, the vas deferens connects with the urethra. The urethra is the tube inside your penis. It’s same tube that urine travels through when you pee.   

You can tell whether you have been circumcised by looking at your penis. Some boys have loose skin at the end of the penis that slides back to uncover the tip of the penis. This loose skin called the foreskin. If you still have a foreskin, you haven’t been circumcised.

*Circumcision helps prevent germs from collecting under the foreskin.

The uterus is the large triangular organ between the fallopian tubes. The uterus is also called the womb and it’s the place where a baby spends the 9 months before it is born, growing and developing. At the bottom of the uterus is the cervix, a knob of flesh with a small hole in the center. One purpose of the cervix is to help keep germ from entering the uterus. It also helps contain the baby inside the uterus. When the baby is ready to be born, the hole in the middle of the cervix widens so that the baby can leave the uterus and enter the vagina.

The vagina is the passageway into and out of a woman’s reproductive organs. By putting his penis into a woman’s vagina, a man can place sperm in her body. The vagina is also the way a baby gets out its mother’s body. The walls of the vagina are very elastic and can stretch wide enough to make room for a penis and even for a baby.

Twins can occur in another way as well. In this case, a fertilized egg splits completely in half, forming two separate babies. Since they started out from the same fertilized egg, these twins are identical. Not only do they look alike, but they are both the same sex.
