Essential Question
What systems of the body are
essential to reproduction?
Standard
B.10A - describe the interactions that occur among systems
that perform the functions of regulation, nutrient
absorption, reproduction, and defense from injury or illness
in animals

Reproductive
Endocrine
Sexual Development
• Puberty:
–period of rapid growth and sexual maturation
–reproductive system becomes fully functional.
–at end, reproductive organs are fully
developed.
–onset is usually between the ages of 9 and 15
–usually starts one year earlier in females than
in males.
Sexual Reproduction
•The Reproductive system
–produces, stores, and releases
specialized sex cells (gametes).
–the fusion of sperm and egg
forms a “zygote”.
Zygote: the single cell from which
all cells of the human body
develop
REPRODUCTIVE SYSTEM
• Main Parts/Key words:
–Male:
• Testes
–produce sperm
–Female:
• Ovaries
–produce the Eggs
• Uterus
–where a baby develops
REPRODUCTIVE SYSTEM
• Main Functions:
–Sexual maturation (puberty)
–Male function:
• produce & deliver sperm
–Female function:
• produce eggs
• nourish & support an embryo
• New section/system
ENDOCRINE SYSTEM
(glands/hormones)
• Hormones used:
– Testosterone
• Male sex traits
– Follicle-stimulating hormone
(FSH)
• Egg & sperm development
– Luteinizing hormone
• Egg release during
menstruation
– Estrogen
• Female sex traits
– Progesterone
• Maintains uterine lining
What is the menstrual cycle?
1. developed egg is released from an ovary.
2. lining of uterus thickens and prepares to receive an egg.
3. If egg is fertilized it is implanted in the uterus and begins
growing into an embryo.
4. If the egg is not fertilized, the entire uterine lining is discharged
(shed)
• Controlled by feedback loops & takes an average of 28 days.
Path of the Egg (Ova)
The Menstrual Cycle
*Most females menstruate during the first 3-7 days of the cycle.
The Menstrual Cycle
Regulated by hormones. A spike in the levels of
each hormone released regulates a specific action
in the cycle.
Ovulation
FSH: stimulates the growth of
ovarian follicles in the ovary before
the release of an egg
Estrogen: stimulates the growth of
the uterine lining
LH: stimulates ovulation
Progesterone: Prepares uterine
lining in anticipation of fertilization.
If the egg is not fertilized the lining
will be shed.

DEBRIEF QUESTION:
Write this question in your Cornell
Notes and answer in 35 words: Explain
how hormones help with reproduction.
DEBRIEF ANSWER:
Hormones stimulate gamete production and
sexual development, and regulate the
menstrual cycle for fertility.
Diseases and Disorders of the Male
Reproductive System
Disease/Disorder Description
Prostate cancer
Most common form of cancer in men over
40; risks of developing it increase with age
Prostatitis
Inflammation of the prostate gland; may be
acute or chronic
Testicular cancer
Malignant growth in one or both testicles;
more common in males 15–30 years; more
aggressive malignancy
Diseases and Disorders of the Female
Reproductive System
Disease/Disorder Description
Breast cancer
Second leading cause of cancer deaths in
women; classified as stage 0 to 4
Cervical cancer
Slow to develop; Pap smear detects
abnormal cervical cells
Cervicitis
Inflammation of the cervix usually due to an
infection
Dysmenorrhea
Condition with severe menstrual cramps
limiting normal activities
