Pd.2

2. Role & Function
The production of steroid hormones.

3. Role and Function Organs that make gametes
Gonads in males are the testes
Gonads in females are the ovaries
Gametes are haploid germ cells.
In males they are spermatozoon and in the females they are the egg cells.

4. Location
FEMALE
Ovaries are on both sides of the uterus below the opening of the fallopian tubes
MALE
Testes hang in a pouch of skin called a scrotum outside the male body

5. Female Hormones Estrogen and Progesterone Steroid Hormone
Controls the cyclic changes within the uterus
Ripening and discharge of the egg to be fertilized
Prepare the lining of the uterus to receive a fertilized egg
This linings subsequent dismantling
*All the events that occur as part of every women’s menstrual cycle*

6. Male Hormone Testosterone Steroid Hormone Occurs in men
Stimulates development of male secondary sexual characteristics

7. Disease #1 DHT Deficiency Dihydrotestosterone
Mutant gene inhibits the conversation of testosterone into DHT
Testes don’t descend into the scrotum
External genitalia is ambiguous
Internally male
Onset puberty  testosterone released

8. Disease #2 Hypogonadism
Occurs when your sex glands produce little or no sex hormones
Sex hormones help control sex characteristics
Breasts and testicle development and pubic hair growth
Play a role in menstrual cycle and sperm production
In females:
- Loss of menstruation
- Hot flashes
- Loss of body hair
In males:
- Breast enlargement
- Decreased body hair
- Muscle loss
- Sexual issues

9. Fun Facts
Females are born with all the eggs they will ever have. Males don't start to make sperm until puberty, and continue to make new supplies their whole life.
Andropause is male menopause. It is the result of a gradual drop in testosterone.
The testes hang away from the body in the scrotum because sperm needs to be kept a few degrees cooler than body temperature to function best.
