Boys bits

Foreskin: the skin that covers the penis (and folded over the glans) is known as the foreskin.

Some boys have this skin removed for religious or health reasons during childhood.

Penis: this is a shaft shaped organ that hangs outside your body, with a section inside the body.

Urethra: this runs from the bladder to the end of the penis and carries both semen (the fluid that contains the sperm) and urine.

Vas Deferens: the job of these tubes is to carry sperm to the urethra prior to ejaculation.

Testicles: (also known as balls) these are two small glands found below the penis, which produce millions of sperm every day (each testicle produces 1000 sperm per second - together that works out at about 172 million sperm a day).

Scrotum: this pouch of skin contains the testicles.

During puberty the scrotum becomes baggy, enabling the testes to hang away from the body, thereby keeping the temperature down and allowing sperm to be produced.

Girls bits

Clitoris: small pea-shaped bit, situated near where you pee - very sensitive during sex.

Vagina: the passage leading from the womb to the outside of your body.

Cervix: also known as the neck of the womb (uterus).

This lies between the vagina and the womb.

Uterus: also known as the womb.

This is an upside down pear shaped organ, where a foetus grows during pregnancy.

Ovaries: these are two tiny organs (kidney bean sized) that lie on either end of the fallopian tubes.

Their job is to hold the thousands of unripe eggs every female is born with.

The ovaries release one egg a month.

Fallopian tubes: these connect the ovaries to the womb.

It is through these tubes that an egg travels on its way to the womb.

The monthly journey of an egg from the ovaries to the uterus (womb)
Oestrogen is created & the cycle starts

An egg is released

It travels along the fallopian tube ready for fertilisation

If it is not fertilised, the egg dissolves
