Sexual And Reproductive Anatomy Quiz

Hormones impact physical characteristics like body hair, genital growth and height as well as emotional characteristics like mood swings, attraction and fantasies. Hormones don't determine our future as people can learn coping mechanisms in order to choose how they behave based on these emotional and physical changes.

The foreskin is often attached to the end of the penis in young people and over time it is able to be pulled back to uncover the glans (head) of the penis. The foreskin produces a waxy substance that needs to be regularly cleaned. Sometimes people remove the foreskin of their penis, this is called circumcision.

The anus is where feces (poop) leave most bodies. The anus has many nerve endings which some people find pleasurable to touch or put things in.

Egg cells are present in the ovaries of a body when that person is born. Usually starting at puberty those cells will develop and begin to release (ovulate) starting a menstrual cycle.

During ovulation, the fallopian tubes with 'catch' an egg cell as it travels towards the uterus. This is where a sperm cell can meet and fertilize an egg cell. However, a potential pregnancy does not occur until that fertilized cell implants in the uterus.

The scrotum often grows larger and the skin becomes darker during puberty. Temperature changes and arousal can also effect how low a scrotum will 'hang'.

Bodies with a vulva have multiple labia (inner and outer). The size length and color of the labia are going to be different for everyone. Outer labia will often grow hair and inner labia may hang higher or lower than outer labia. All different types are valuable and healthy.

A body with ovaries has all of its egg cells present at birth stored in ovaries. Starting at puberty ovaries produce the hormones estrogen, progesterone and testosterone. The amount of each hormone will differ from person to person.

The vulva is the external genitals made of multiple body parts including the clitoris, labis, urethra opening and vaginal opening. This is often called the 'vagina' but the vagina is an internal organ.

The penis contains a urethra which passes both urine and semen. However, urine and semen can't come out at the same time.

Usually sperm cell production begins at puberty for people with testicles and continues throughout the rest of their life.

The clitoris is a pleasure organ that can become erect when aroused. The external part of the clitoris is located in the vulva, but also includes internal parts under the labia and around the vagina.

Usually people have 23 pairs or 46 chromosomes in all of their cells. These come from the sperm and egg cells that created us carrying our genes which determine everything from our eye color to how tall we will grow. There are reasons why some bodies have more or less chromosomes which will effect how they grow and develop.

While all bodies can pass urine through a urethra, bodies with a penis usually also can pass semen out of the body, this is called ejaculation. For bodies with a vulva, the urethra opens in the vulva and is separate from the vaginal opening.

The cervix is important to the health of the uterus. The mucus it creates also assists in keeping sperm cells alive which aids in fertilization. The cervix can also expand (dilate) for a baby to leave the uterus if someone chooses to carry a pregnancy to birth.

Some people say that the brain is the most important sex organ. Not only does it control the beginning of puberty, but it also helps us feel and remember our likes and dislikes. Our brain also helps us with communication which is important to everyone's sexuality.

Testicles produce sperm cells starting at puberty and usually continue throughout life. Testicles also produce the hormones testosterone and estrogen. The amount will differ person to person.

The pituitary gland secretes hormones and communicates with gonads (overies and testicles) to begin puberty.

The vagina is a very muscular organ which regularly creates fluids to protect and clean itself. When this comes out of the body it is called 'discharge' and is a common, healthy thing.

The fallopian tubes are a passageway for egg cells to travel to the uterus. The vagina is a passage way for menstrual blood ('period') or a baby to travel out of the body from the uterus if someone chooses to carry a pregnancy.

While the testicle produces sperm cells, those cells need a location to develop (mature) and be stored. This is where the epididymis comes in. If the cells do not mature they cannot fertilize an egg (if that is what someone wants to do).

The vas deferens transport sperm cells to the prostate where they mix with other fluids to become part of semen.

The prostate also provides fluid that makes semen, however most of semen's fluid comes from the seminal vesicles. The seminal vesicles attach to the vas deferens just above the prostate.

The seminal vesicles make up most of the fluid that makes semen, but the prostate also adds fluid as well. The prostate is also where the vas deferens and the urethra meet so semen can leave the body through ejaculation.
