• 1 in 90 people is intersex
• Biological, very different from transgender!

Raven van Dorst is visible in the photo. You might know them from TV.

Raven was born with true hermaphroditism (a form of intersex) and refers to themselves as a hermaphrodite. 

On doctors' advice, Raven's parents had the external male genitalia surgically removed shortly after birth. Raven describes this procedure and its consequences as traumatic.

Intersex is a group of people with a lot of variation!

The way in which people are intersex varies a lot.

What they have in common is that all of them have male AND female sexual characteristics

!

You are born intersex. It happens because of your DNA.

When someone is trangender they decide that their gender doesn't match their sex

Hymen

There can be a hymen:

• In most cases doesn't close off vagina
• Differs in size
• Sometimes no hymen

This is the entrance to the vagina, which is a tube that connects to the uterus.

Both labia can produce a liquid during sex,

This liquid works like lube (=glijmiddel)

They can also become hard

When a woman pees, it comes out of the urethra.

Which is different from the vagina!

Very sensitive to stimulation

makes a woman orgasm.

Much of the clitoris is on the inside of the body.

Which can fill with blood and become 'stiff'.

uterus

fallopian tube

ovary

bladder

urethra

vagina

clitoris

The scrotum contains the testes.

It regulates the temperature to be slightly lower than body temperature.

This is good for the production of spermcells

The glans (penis) is very sensitive.

It makes a man orgasm

The foreskin is a thin layer of skin which covers the glans.

During an erection the glans becomes visible.

Men who are circumsized have their foreskin removed.

This is often done for religious of medical reasons.

When aroused, erectile tissues in the penis fill with blood.

This makes the penis go erect (an erection)

What is average?

The average flaccid penis is 9.16 cm (3.61 inches) in length.

The average erect penis is 13.12 cm (5.16 inches) long.
