KEY CONCEPT Female and male reproductive organs
fully develop during puberty.
2
The female reproductive system produces ova.

• The reproductive system is a collection of
  specialized organs, glands, and hormones that
  help produce a new human being.
• Females and males reach sexuality maturity, or
  the ability to produce offspring, only after
  puberty.
• Puberty marks the time in your life when your
  hypothalamus and your pituitary gland release
  hormones.
• Follicle stimulating hormones (FSH) and
  luteinizing hormones(LH)

3
The female reproductive system produces ova.

• There are two main functions of the female
  reproductive system.
• produce ova, or egg cells
• provide a place where a zygote develops

4
The female reproductive system produces ova.

• The egg cells are produced in the ovaries.
• The ovaries are paired organs located on either
  side of the uterus, or womb.
• When a female baby is born, she has all of her
  eggs.

5

• Follicle-stimulating hormones and Luteinizing
  hormones stimulate the release of Estrogen.
• Estrogen has three main functions

• develop female sexual characteristics
• Ex widening the pelvis, increasing fat deposits
  and bone mass, and enlarging the breasts.
• develop eggs
• prepare uterus for pregnancy and maintain a
  pregnancy when it occurs

6

• When the egg cell matures each month, it is
  released from an ovary and enters the fallopian
  tube.
• An egg takes several days to travel through the
  fallopian tube, during that time it can be
  fertilized by sperm that enters the tube.
• When the egg is fertilized it will attach to the
  wall of the uterus, if it is unfertilized it will
  eventually be broken down and discarded.

7

• The uterus is made up of 3 layers
• A thin inner layer of epithelial cells
• A thick middle layer of muscle
• An outer layer of connective tissue
• The lower end is called the cervix, which opens
  to the vagina.
• During a normal birth, a baby is pushed down the
  canal of the vagina to exit the mothers body.

8
The male reproductive system produces sperm.

• There are two main functions of the male
  reproductive system.
• produce sperm cells
• deliver sperm to the female reproductive system

9
The male reproductive system produces sperm.

• Males do not produce sperm until after they reach
  puberty
• Sperm production takes place in the testicles, or
  testes
• Each testis contains hundreds of tiny tubules
  where millions of sperm cells are produced.

10

• LH stimulates the release of testosterone
• Testosterone has two main functions.

• Controls developing male sexual characteristics
• Ex deeper voice, more body hair, greater bone
  density, increased muscle mass
• producing sperm

11

• The testes are enclosed in a pouch called the
  scrotum which hangs below the pelvis outside the
  body.
• It is 2-3 degrees cooler then the core body
  temperature
• Sperm cannot develop if the temperature is too
  high
• When the sperm leaves the testes, they travel
  through a duct to a long coiled tube known as the
  epididymus.
• Sperm matures there and remains until expelled
• During sexual stimulation, the sperm travel into
  another long duct called the vas deferens

12

• Secondary sex glands secrete fluids into the vas
  deferens to nourish and protect the sperm.
• The prostate gland produces a fluid that helps
  sperm move more easily.
• The bulbourethral gland and the seminal vesicle
  secrete basic fluids that help neutralize the
  acidity in the urethra and in the females vagina.
• The fluids from all 3 glands plus sperm form
  semen.
• Semen moves from the vas deferens into the
  urethra and ejects it from the penis.
