Title: Male and Female Reproductive Systems


1
Male and Female Reproductive Systems
  • Includes all internal and external parts.

2
Female System
  • Functions
  • Produce an Ovum (egg cell)
  • When united with the sperm produces a fertilized
    ovum.
  • No fertilization-Menstrual cycle
  • Organs of intercourse

3
External Organs
  • Called the Vulva (includes)
  • Clitoris
  • Mons Pubis
  • Labia Majora
  • Labia Minora
  • Vaginal Opening
  • Vestibule

4
External Organs
  • Mons Pubis rounded fatty pad of tissue, covered
    with pubic hair, located in the front on top of
    the pubic bone.
  • Labia Majora Outer two folds of tissue on
    either side of the vaginal opening, also covered
    with pubic hair.
  • Labia Minora Inner two folds of skin, forms a
    hood like covering over the clitoris.
  • The labia serve as a line of protection against
    pathogens (infection), also function in sexual
    arousal.

5
Vaginal Opening
  • Hymen Thin membrane that stretches across the
    vaginal opening.
  • Clitoris Small knob of tissue in the front of
    the vaginal opening, important in sexual arousal.
  • Bartholins Glands Produce a lubricating liquid
    during sexual arousal
  • Urethral opening Area where urine leaves the
    body.

6
Internal Organs
  • Vagina Elastic, tube like passageway. Organ of
    sexual intercourse. Also known as the Birth
    Canal.
  • Cervix Neck of the uterus or the opening to the
    uterus, during child birth the cervix will dilate
    to allow the passage of the baby.
  • Uterus Strong, elastic muscle about the size of
    a fist. Main function is to hold and nourish the
    developing embryo and fetus.
  • Fallopian tubes Tubes on each side of the
    uterus. Path way for the ovum.
  • Ovaries female sex gland situated on both sides
    of the uterus at the ends of the fallopian
    tubes. Houses the ova and produce the hormones
    estrogen and progesterone.

7
Ovulation
  • The process of releasing the one mature ovum each
    month into the fallopian tube is called
    ovulation.
  • The ovum can live for two days in the fallopian
    tubes.

8
Menstruation
  • If the ovum is not fertilized, or if the
    fertilized ovum does not attach to the wall of
    uterus, the lining is not needed.
  • The muscle of the uterus contracts will cause the
    lining to gradually break down.
  • Abdominal Cramps
  • 2-3 Tablespoons of blood
  • The rest of the tissue that make up the lining.
    The process will take anywhere from 4 to 7 days.
  • The cycle repeats itself every 24-36 days
    depending on the person.
  • The cycle will start around the ages of 10-15.
  • Menopause the ceasing of menstrual cycle, 45-50
    on the average.

9
Concerns about the female system
  • PMS Premenstrual Syndrome, Last from several
    days to two weeks.
  • Symptoms Nervous tension, anxiety,
    irritability, bloating, weight gain, depression,
    mood swings, and fatigue.

10
Concerns with PMS
  • Dysmenorrhea Painful contractions, lasting for
    days, avoid aspirin.
  • Amenorrhea Lack of the menstrual cycle, a 16
    yr.old female who has never had a period or one
    that has discontinued for three months or more.
  • Toxic Shock Syndrome (TSS) Caused by a
    bacterial infection. Most cases have been traced
    to the use of super absorbent tampons which
    provide an oxygen rich environment for the
    bacteria.
  • Vaginitis Vaginal infection which is common,
    yeast infection is one example.

11
Other Concerns and Side Effects
  • Sterility
  • Blockage in the fallopian tubes
  • Unable to ovulate
  • Endometriosis Endometrial tissue grows outside
    the uterus
  • Untreated STIs (gonorrhea, Chlamydia
  • Breast Cancer (Most common in women)
  • Cervical Cancer Pap Smear to detect . It will
    not detect STIs.
  • Ovarian Cancer
  • Lining of the Ovary

Male Reproductive System
  • Function To produce sperm cells
  • Male reproduction cell (sperm cell) unites with a
    female egg cell (ovum) to form a fertilized ovum.
  • Production starts around 12 to 15 years of age.
    Otherwise known as puberty.
  • Testosterone causes the testes to produce sperm.
  • Spermatogenesis Production of sperm for the
    rest of the males life.

14
External Male Reproduction System
  • Testes Male sex glands, manufacture the male
    sex hormone. Testosterone and produce male
    reproduction cell sperm.
  • Scrotum Sac that holds the testes.

15
  • Testes Seminiferous tubules sperm is produced
    in this section of the testes.
  • 500 million each day.
  • Epididymis Stores newly produced sperm. 64
    days for sperm to fully mature.

16
Penis
  • Tube like organ that functions in sexual
    reproduction, sexual pleasure and the elimination
    of body waste.
  • Erections Blood fills three cylinders (sinus)
    which surround the urethra.
  • Ejaculation Release of reproductive fluids.
    (Semen)

17
Circumcision
  • Foreskin The fold of skin that covers the head
    of the penis. Males are born with this.
  • Surgical procedure to remove this fold of skin.
  • Usually done after a few days of birth.
  • Aids in keeping the reproductive organs clean.

18
Internal Reproductive Organs
  • Vas Deferens A long tube that connects the
    epididymis with the urethra.
  • Seminal Vesicles Two little pouches just above
    and either side of the prostate gland. Secrete a
    fluid that mixes with the sperm. The fluid
    travels down the ejaculatory duct to mix with the
    sperm.
  • Prostate Gland Below the bladder and surrounds
    the urethra. Secretes a milky and alkaline fluid
    that mixes with the sperm. It it the size of a
    chest nut.
  • Cowpers Gland Glands open into the urethra,
    secretes a clear sticky fluid that will clean the
    urethra of acid from urine.
  • Urethra Tube like organ that travels thru the
    penis and leads to the ejaculatory duct, passage
    way for urine and sperm.
  • Semen Mixture of fluids from the seminal
    vesicles, cowpers gland, and the prostate gland.

19
Concerns about the male system
  • Nocturnal Emissions
  • Hernia Pushing of a body part thru the muscle
    wall that normally contains it.
  • Inguinal Hernia Weak spot in the abdominal wall
    near the top of the scrotum. Part of the
    intestine will push thru.
  • Sterility Weak malfunctioning sperm or no
    sperm. Can be caused by temperature changes,
    surgery, certain chemicals, smoking, contracting
    the mumps as an adult, untreated STIs.

20
Other Concerns
  • Testicular cancer 1of all cancer in men ages
    15-34.
  • Prostate cancer Prostate enlarges and blocks
    the urethra or bladder. 2nd most common type of
    cancer in men.
