How does the male reproductive system work?


Everybody looks different but it is helpful to know what and where things are. The male body comes in different shapes, colors and sizes but everyone should get to know what it looks like.

Male anatomy

  • Seminal Vesicles: the two seminal vesicles secrete a thick fluid that provides energy to the sperm
  • Urethra: is a tube that carries semen and urine (pee) out of the penis
  • Bladder: is a muscular sac that stores urine until it released through the urethra
  • Prostate Gland: walnut-sized gland which surrounds a portion of the urethra and produces some of the fluid in the semen
  • Epididymis: is beside each testicle, it is a tube where sperm is stored. Sperm is then transported to the vas deferens
  • Vas Deferens: is a muscular tube that transports sperm from the epididymis to the urethra
  • Scrotum (ballsack): hangs under the penis and holds the testicles and epididymis
  • Penis: is made of two parts; the shaft (the main part) and the glans (the tip/head of the penis). The penis delivers sperm and urine through the urethra. It also becomes erect (hard) through spongy tissue located in the shaft which is filled with blood when excited.
  • Testicle/Testis: there are 2 testicles which produce sperm and the sex hormone testosterone.
  • Pubic Bone: a bone that protects the pubic area

What to expect while going through puberty

For males it is common to start getting erections in the morning (morning wood). It is also common to wake up with a wet spot in the bed from ejaculating (cumming) in your sleep. This is all completely natural way of your body developing and changing into an adult. Another common expectation is for the scrotum to progressively drop and become further away from your body.

Each penis is different

All penises come in different sizes and colors. The average erect penis is 5 inches. Research shows there is no major difference in pleasure between circumcised and uncircumcised penises. An uncircumcised penis has a foreskin which protects the head of the penis. All penises work and feel the same, regardless of whether the foreskin has been removed.

Why is my body changing?


Puberty is when your body starts to change and develop to be an adult. Your body is also changing so that you can have babies in the far future. A lot of things are changing, but they are all normal!

What should I expect during puberty?

Some body changes are different for men vs. women, but others are the same.

Same things:

  • Body hair starts growing in your armpits and pubic area. Boys also get facial hair.
  • You start smell, so shower and use deodorant!
  • You grow taller and wider
  • You get pimples
  • Your emotions are everywhere

Male body changes

  • Voice gets deeper
  • Muscles get bigger
  • Penis and testicles(balls) get bigger

Female body changes

  • Breasts begin developing
  • Menstrual cycle begins, meaning you bleed once a month
  • A daily vaginal discharge (white mucus) appears

All of this is very new and different. Everyone goes through these changes. If you have questions, visit the Teen Health Center and we can help!

Why is puberty a thing?

Puberty happens to everyone because it is a way of your body to turning into an adult. Puberty also happens to prepare you to have babies. Males create sperm from their testicles. Females develop eggs from their ovaries. When a sperm and an egg meet they create a fertilized egg. The fertilized egg eventually turns into a baby after many months of being in the female’s uterus.

Explore your body

It is important to explore and know your changing body. When you know your body you are able to tell when it is healthy and when it is not. Different tools that you can use to explore are your hands and a mirror. Get comfortable touching your body. When you are comfortable you are able to know what does and doesn’t feel good. A mirror is useful to help see how your body looks especially the pubic area.
