<p>The male reproductive system <br><br>•The <b>penis</b> hangs at the front of a boy’s body. Penises come in all different colours, shapes and sizes, so there’s no such thing as a ‘normal’ penis. Some penises are short and thick, some are long and thin, some lean to one side. The penis may be darker or redder than the rest of a boy’s skin and may have veins sticking out. Pubic hair grows around the penis, the testes and the anus.<br><br>•The <b>foreskin</b> is a fold of skin that covers the head of the penis. Not every boy has a foreskin because it is sometimes removed. This is called circumcision. The penis works the same way with or without a foreskin. If a boy has a foreskin he should keep it clean by carefully washing under it when he showers or bathes.<br>\n</p>
<p>•The <b>testes</b> (balls) are where sperm is produced after a boy has started puberty. Testes grow bigger during puberty and come in different shapes and sizes. Sometimes one testis (one ball) is larger than the other or hangs lower than the other. This is all normal.<br><br>\n\n• The <b>scrotum</b> is the skin that holds the testes on the outside of the body. This skin is usually a bit darker than the rest of a boy’s skin and may have pubic hairs on it.<br><br>\n\n• The <b>anus</b> is where faeces (poo) comes out. The skin around the anus is usually a bit darker than the rest of a boy’s skin and may have pubic hairs around it.<br>\n\n</p>
<p>•The <b>prostate</b> is where sperm are mixed with fluid called semen. The prostate gland is also involved in ejaculation.<br><br>\n• The <b>urethra</b> is a tube with a small opening at the tip of the penis. It has two functions. It can carry urine (wee) from the bladder, or semen (containing sperm) from the prostate. There is a valve that can block off one or the other, so boys can’t urinate (wee) and ejaculate (release semen) at the same time.<br>\n</p>
During puberty, boys will begin to produce sperm and ejaculate. This means their bodies are able to reproduce.
