1 MALE AND FEMALE REPRODUCTIVE SYSTEMS

2 MALE - Testosterone Seminal Vesicle Vas Deferens Prostate Gland Penis
Urethra Foreskin Bulbo-Urethral Gland (Cowper’s Gland) Testicle Scrotum

3 MALE (cont.) Seminal Vesicle Attached to Vas Deferens
Located near the base of the Bladder Secretes a fluid that mixes with the sperm to provide mobility and nourishment

4 MALE (cont.) Vas Deferens A tube approximately 18 inches long
Carries sperm to the Seminal Vesicle

5 MALE (cont.) Prostate Gland
Secretes the fluid that mixes with sperm to form Semen

6 MALE (cont.) Urethra Connects with the Bladder as well as the Vas Deferens Releases Urine OR Semen Not both simultaneously!!!!!!

7 MALE (cont.) Bulbo-Urethral Gland (Cowper’s Gland) Fluid Producing

8 MALE (cont.) Testicle (Testes) 2 Small Glands Sperm producing Gland
Contains several 100 yards of coiled sperm Normal adult male produces 200 million sperm a day 500 sperm lined up would only measure 1 inch!

9 MALE (cont.) Scrotum Holds the Testicles
Keeps Testes at a temperature slightly below the normal body temp. of 98.6 degrees As body temp. increases the Scrotum lowers (muscles relax) As body temp. decreases the Scrotum raises and the Testes pull in (muscles contract) CLOTHING CAN BE A RISK!!!!!

10 MALE (cont.) Epididymis Larger tube that joins the Testes
A temporary storage facility for Sperm Is where Sperm will mature

11 MALE (cont.) Sperm Cell

12 MALE (cont.) Ejaculation Vasectomy
About million Sperm in each Ejaculation One spoonful of Semen contains Million Sperm Vasectomy Cutting of the Vas Deferens Prevents the Sperm from reaching the Seminal Vesicle to mix with the fluid

13 CANCER OF THE TESTES – AT RISK AGE-GROUP IS
MALE (cont.) Sterility Sperm is weak, malformed or unable to join the egg cell Causes: Temperature changes Exposure to certain chemicals Mumps as an Adult STD’s Testicular and Prostate Cancer (pg. 441) CANCER OF THE TESTES – AT RISK AGE-GROUP IS 15-35!!!!!! That means you guys!!!

14 FEMALE – Estrogen & Progesterone
Fallopian Tubes Ovaries Uterus Cervix Vagina

15 FEMALE (cont.) Ovary Are a PAIR (2) Contains the eggs
All eggs are in place at the time of birth Born with over 1 million IMMATURE egg cells

16 FEMALE (cont.) Fallopian Tubes Are a PAIR (2)
Takes the egg to the Uterus

17 FEMALE (cont.) Cervix Neck of the Uterus

18 FEMALE (cont.) Uterus Pear shaped organ About the size of your fist
Where fertilized eggs grow When the egg is released the lining of the uterus begins to thicken preparing for fertilization

19 FEMALE (cont.) Vagina Tubal (Ectopic) Pregnancy Birth Canal
A muscular, very elastic tube that serves as a passage way to the Uterus Tubal (Ectopic) Pregnancy Egg implants itself in the Fallopian Tube Egg is likely present during the middle of the Female’s monthly cycle

20 Ectopic Pregnancy

21 FEMALE (cont.) Ovulation Menstruation
Can occur more than once per month Menstruation Change in hormone levels can interrupt or extend the cycle Time – more or less than 28 days (average) Prolonged menstrual flow can decrease a woman’s iron level
