An
function of all living things is
reproduction, the process by which life continues from
one
to the next.
Reproductive System – the system of organs involved in
producing
.
Two main Functions:
of Sperm
of Sperm
– male reproductive cells
Testosterone – the male sex
.
Testes (testicles) – two small glands that
sperm; secrete testosterone.
Scrotum –
skin sac where the testes are
located.
Penis – tube – shaped organ that extends from the
trunk of the body just above the testes.
Semen – thick fluid
sperm and other
secretions from the male reproductive system.
Vas Deferens –
that extend from each
epididymis to the urethra.
Urethra – the passageway through which both semen
and urine
the male body.
– as sperm move through the vas
deferens, they are combined with a nourishing fluid
produced by the seminal vesicles.
- secretions from the prostate gland
and Cowper’s glands combine with the sperm –
containing fluid to form semen.

infections
that cause discharge from the penis and burning

Syphilis – bacterial infection;

Genital Herpes – a
that causes
periodically occurring blister like sores in the
genital area.
Inguinal Hernia –
of tissue that allows
part of the intestine to push into the abdominal wall
near the top of the scrotum.
Lumps in the groin, pain, partial or complete blockage
of the intestine.
Sterility – the

Exposure to X-Rays / radiation, use of drugs, steroids,
STD’s.
Testicular Cancer
Undescended testicle, abnormal testicular development,
family history.
1. What is the function of the testes?
2. Describe the path that sperm follow
from the time they form until they
leave the body.
3. What are the symptoms of testicular
cancer? Identify situations requiring
professional health services for
preventive care.
Several Functions:
female sex hormones
Stores female reproductive cells (
)
– a hollow, muscular, pear – shaped
organ inside a female’s body, nourishes and protects the
fertilized ovum from conception until birth.
Ovaries – female sex gland that store the ova and
produce female sex
.
Ovulation – the
of releasing a mature
ovum into the fallopian tube each month.
– a pair of tubes with
fingerlike projections that draw in the ovum.
Vagina – a muscular, elastic
that
extends from the uterus to the outside of the
body.
Zygote – Fertilization of an
by
a sperm cell.
Each month the uterus prepares for
pregnancy.
If pregnancy does not occur, the endometrium isn't
needed; breaks down through blood, tissue and fluids.
– opening to the uterus that materials pass
through.
Menstruation –
Normally occurs around
of the uterine lining.

Menstrual Cramps – Sometimes occur at the
of a
menstrual period.
Light exercise or heating pad may help relieve symptoms.

Nervous tension, anxiety, irritability, bloating, weight gain,
depression, mood swings, fatigue.

bacterial infection that affects the immune system and the
liver; can be fatal.
Fever, vomiting, diarrhea, sunburn like rash, red eyes,
dizziness, muscle aches.
Endometriosis – painful,
disease
occurs when tissue that lines the uterus migrates and
grows in the ovaries, fallopian tubes, and the uterus.
Pelvic Inflammatory Disease (PID) –
of
the fallopian tubes, ovaries and surrounding areas.
Sexually Transmitted Disease – most common
causes of
and other disorders.
Vaginitis – Bacterial vaginosis,
common
vaginal infection in women of childbearing age.
Blocked Fallopian Tubes – leading cause of

Ovarian Cysts –
– filled sacs on the ovary.
Cervical, Uterine, and Ovarian Cancer – Early
sexual activity and STD’s such as
(HPV) are related to an increased incidence of cervical
cancer.
1. How do the structures in the
fallopian tubes help move the ovum
from the ovaries to the uterus?
2. Explain ovulation, fertilization and
menstruation.
3. List 3 causes of infertility in females.
