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


– 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.

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.

 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.

disease
occurs when tissue that lines the uterus migrates and
grows in the ovaries, fallopian tubes, and the uterus.

– 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.

fallopian tubes help move the ovum
from the ovaries to the uterus?
