Reproductive Reproductive SystemsSystems

Sperm – the sex cells that are made by males and that are needed to fertilize eggs.

Testes – the male reproductive organs that produce sperm and testosterone.

Scrotum – the skin covered sac that surrounds the testes.

Epididymis – once sperm are made

they move into this coiled tube. Vas Deferens –

once a sperm matures, it travels into this tube.

Semen – sperm and the added fluids.

Urethra - the tube that passes through the penis. Sperm leave the body during ejaculation via this tube.

Prostate Gland – the male gland that adds fluid to the sperm to nourish and protect it.

Penis - the organ that

removes urine from the male body

and that can deliver sperm to the female reproductive

system.

                                                           

 

Testosterone - the male hormone made by the testes.

How long does it take an immature sperm to mature?

An immature sperm takes 2 – 10 days

to fully mature.

What are some signs that a male is going through

puberty?Shoulders get wider& develop muscles

hair grows on the face and other body parts

voice deepens

At this time testosterone also causes the body to start

making sperm.

Eggs - the sex cells of females that can be fertilized by sperm.

Ovaries – the female

reproductive organs that

produce eggs and

hormones.

Fallopian Tubes – connect the ovaries to the uterus.

Uterus – the muscular organ the size of a fist where fertilized eggs develop.

Cervix - the narrow base of the uterus.

Endometrium – the lining of the uterus that thickens as an egg matures.

Placenta - a blood vessel-rich tissue that forms in a mother’s uterus.

Vagina - reproductive organ that connects the uterus to the outside of the body.

If an egg is not fertilized, the blood vessels in the endometrium break

down. The process in which the blood and

tissue that built up in the uterus flows out of the body through the vagina.

a monthly series of hormone-controlled

changes that mature an egg and prepare the uterus

for pregnancy.

What are some signs that a female is going through

puberty?

Increase in height & weight

Growth of hair under the arms and pubic region

Increase in perspiration

Onset of menstrual periods

Growth of darker hair on the legs

Increase in breast size

Widening of the hips

What are the two female hormones our body produces?

Girls have all their eggs at birth. On average, how many

are there?

Estrogen and Progesterone

Over 2 Million

When do eggs mature?Eggs begin to mature when a girl reaches puberty

How often do eggs mature?

One egg matures every 28 days

Where are eggs fertilized?

In the fallopian tubes

Not engaging in any kind of sexual activity with a partner

Any vaginal, oral, or anal intercourse
