1. KEY CONCEPT Female and male reproductive organs fully develop during puberty.
Reproductive system – composed of specialized organs, glands, and hormones

2. Puberty – (sexual maturity) Hypothalamus and pituitary gland secrete hormones – follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to begin the development of sexual characteristics.
Girls = yrs. old Boys = yrs. old

3. The female reproductive system produces ova.
There are two main functions of the female reproductive system.
produce ova (ovum), or egg cells in the ovaries (2) until menopause ( yrs.)
have 2 million potential eggs when born (start in womb)
provide a place where a zygote develops (womb or uterus)
uterus
cervix
rectum
vagina
urethra
urinary bladder
pubic bone
ovary
fallopian
tube

4. Estrogen has three main functions. (steroid hormone)
develop female sexual characteristics such as widened pelvis, increased fat/bone mass, enlarged breast size
2. develop eggs (meiosis- 1 egg/3 polar bodies)
3. prepare uterus for pregnancy every month

5. An Egg cell matures each month and is released from one ovary. (R or L). Egg travels down the fallopian tube (4 in.) over several days to the uterus. Eggs are fertilized in the fallopian tubes. The uterus is the size of a pear. The cervix is the opening of the uterus. The cervix must dilate and efface for childbirth to begin. (4 in.)

6. The male reproductive system produces sperm.
There are two main functions of the male reproductive system.
produce sperm cells (entire lives) in testes (testicles)
deliver sperm to the female reproductive system
urinary bladder
vas deferens
pubic bone
prostate gland
penis
urethra
testis
scrotum
epididymis
bulbourethral
gland
rectum
seminal vesicle

7. Testosterone has two main functions. (steroid hormone)
developing male sexual characteristics- deeper voice, increased muscle mass, body hair, increased bone density
producing sperm

8. Male Reproductive System
Testes are contained within the scrotum.
Keeps temperature 2-3 degrees lower.
Epididymus – tube where
sperm mature
Vas deferens – duct
sperm travels to leave the
body through the urethra
(Vasectomy)
Prostate gland, bulbourethral
gland, seminal vesicle add
fluids to create semen. Fluids
nourish, protect against acidity.
