Functions of the Female Reproductive System
Produce ovum, Maintain the fertilized egg, Maintain the embryo
Structures:




Ovaries: Have 2 main functions: Ovulation and production of hormones
(estrogen & progesterone)
Uterus: is peared shape and measures approx 3 inches. Receives and nurtures
embryo during development
Fallopian Tubes: convey ovum to uterus
Fimbrae: fingerlike projections lined by tiny hair like cilia that assist the ovum
to travel to the uterus.

Vagina: receives sperm & serves as birth canal for the fetus
Cervix: lower part of the uterus
Perimetrium: Outer layer of the uterus
Myometrium: middle layer of uterus. Muscle
Endometrium: inner layer of the uterus
Structures of the Female Reproductive System






Mons Pubis: Fatty
tissue on pubic
symphysis.
Labia Majora: Protects
external genital
structures
Labia Minora: Protects
vaginal and urethral
openings
Clitoris: Erectile tissue
and is richly supplied
with nerves
Bartholin Glands:
small pea-sized glands.
Produce a mucoid
secretion to lubricate
the vagina and vulva.
Skene’s Glands:
Secrete mucus.
"On the Rag"





Originated sometime between 19th to 20th
century.
When a woman was menstruating, she was
“on the rag,”
Each woman had a supply of rags for specific
use during menstruation.
Layer rags together, use pins to attach the
rags to their panties.
Women would wash the rags and hang them
out to dry.
Menstrual Cycle
Normal cycle length is considered 28
days
 varies from female to female
 Bleeding as a result of menstruation
lasts 2 to 7 days on average
 An average loss of 20 to 80mL of
blood.

Three Phases during Menstrual Cycle
1.
2.
3.
Proliferative Phase:
Preparing for Ovulation endometrium begins to
grow after menstruation.
Secretory Phase:
Preparing for Implantation
- endometrium is
becoming ready for the
implantation of a
blastocyst.
Menstrual Phase: If no
implantation occurs, the
endometrium breaks
down and is discharged
in menstruation.
Proliferation Phase: Preparing….





Proliferation Phase starts in the anterior pituitary
gland with the release of FSH (follicle stimulating
hormone)
FSH goes to the ovaries and causes the ovarian
graafian follicle (OVUM) to develop/mature & ripen.
Follicle begins to mature - releases ESTROGEN
Estrogen causes the uterine lining to thicken in
preparation of the ovum (egg) and causes the ovum to
ripen and enlarge.
When estrogen levels get high enough they cause the
release of LH or luteinizing hormone
Secretory Phase: Ovulation






Secretory Phase---extends from the day of ovulation to
about 3days before the next menstrual period.
LH causes the release of the ovum or OVULATION
The follicle pops and the ovum comes oozing out
causing a crater on the side of the ovary to be formed
The “crater” that is left on the side of the ovary oozes
PROGESTERONE.
After ovulation, a large amount of progesterone is
produced.
Progesterone causes the uterine lining to thicken in
preparation for implantation of a fertilized ovum.
Menstrual Phase: NO BABY





No fertilization of the ovum occurs in the
fallopian tubes and the ovum deteriorates.
If fertilization and implantation does not occur,
progesterone and estrogen levels decrease
The hypothalamus secretes gonadotropinreleasing hormone (GnRH) that stimulates the
anterior pituitary to secrete FSH
Menstruation begins which marks the first day
of the new menstrual cycle.
Rising levels of FSH trigger the beginning of
the next phase, called the proliferative phase
The Ovarian Cycle




The normal ovulatory cycle is divided into two
phases called the follicular and luteal phases.
Different levels of hormones are released.
Follicular Phase: is initiated from the day
bleeding stops and finishes with a midcycle
surge of LH.
Luteal Phase: this is initiated with the midcycle surge of LH which coincides with
ovulation and ends with the first day of onset
of the period.
Menstrual Disorders





Dysmenorrhea–painful menstruation.
Amenorrhea–absence of menstruation.
Polymenorrhea–menstrual cycles of less than
21 days.
Oligomenorrhea–diminished menstrual flow
that is not amenorrhea.
Interventions based on cause of disorder.
Amenorrhea Cessation of Menstruation
2 Types Primary & Secondary


Primary
Absence of
menstruation in a
woman by the age
of 16.


Secondary
Menstruation has
stopped for 3 months
in a woman with a
history of regular
cyclic bleeding, or 6
months in a woman
with a history of
irregular periods.
Dysmenorrhea





Severe uterine pain during menstruation.
Pain - sharp, throbbing, dull, burning, shooting
Nausea and vomiting, diarrhea, headache, fainting,
and fatigue.
Heavy blood loss, known as menorrhagia.
Release of prostaglandins and other inflammatory
mediators in the uterus is thought to be a major
factor in primary dysmenorrhea.
Metrorrhagia, Menorrhagia


Metrorrhagia: heavy bleeding between
periods, or bleeding unrelated to the
menstrual period.
Menorrhagia: menstrual bleeding that lasts
more than 7 days or bleeding that is much
heavier than usual for the individual.

Modified radical
mastectomy
Simple Mastectomy (Total)



A surgical procedure to
remove the whole
breast that contains
cancer.

nodes under the arm
may also be removed
for biopsy.
Dotted line shows
entire breast is
removed. Some lymph
nodes under the arm
may also be removed.
Modified Radical Mastectomy

remove the whole breast
that has cancer, many of
the lymph nodes under the
arm, the lining over the
chest muscles, and
sometimes, part of the
chest wall muscles.
Dotted line shows entire
breast and some lymph
nodes are removed.
Part of the chest wall
muscle may also be
removed.
Lumpectomy and Partial Mastectomy



Partial Mastectomy: A surgical
procedure to remove the part of
the breast that contains cancer
and some normal tissue around
it. This procedure is also called
a segmental mastectomy.
Lumpectomy: A surgical
procedure to remove a tumor
and a small amount of normal
tissue around it.
Breast-conserving surgery.
Dotted lines show area
containing the tumor that is
removed and some of the
lymph nodes that may be
removed.
Sentinel lymph node mapping





A method of determining
whether cancer has spread
beyond the primary tumor and
into the lymph system.
Blue dye is injected into the
area around the original
cancer site.
The dye moves to the first
lymph node (sentinel node)
that drains close to the cancer
site.
Forms a map pattern of
lymphatic fluid.
The map can show where the
cancer is likely to spread and
which lymph node is most
likely to have cancer cells.
Functions of the male reproductive system



Hormone production
Deposit Sperm
Spermatogenesis
Major Structures:



Glans Penis: urination
and deposit semen
Scrotum: encloses the 2
testes and maintains
temperature suitable for
sperm production.
Testes: Produce sperm.
Produce and secrete
testosterone.
Structures of the male reproductive system.








Epididymis: stores maturing
sperm
Vas Defrens: carries sperm
upward from epididymis to the
ejaculatory duct.
Ejaculatory Duct: During
ejaculation, semen passes through
the ducts and exits the body via the
penis.
Spermatic Cord: Cord-like
structure formed by the vas
deferens and surrounding tissue.
Cowper’s Glands: secrete fluid
that neutralize urine acidity in
urethra prior to passage of semen.
Seminal Vesicles: secrete fluid
high in fructose to nourish sperm.
Prostate Gland: secretes fluid that
initiates sperm movement and
nutrition.
Urethra: passage of urine and
semen
Cryptorchidism

ipsilateral scrotum.
Most testes descend by the
first year of life (the majority
within three months)
Phimosis







A condition in which the foreskin is tightly stretched around the head of
the penis and cannot be pulled back freely.
Can occur naturally.
Triggered by an infection under the foreskin or chronic conditions.
A very tight foreskin may interfere with urination or sexual function.
Prevented by good hygiene.
Treatment with certain medicated creams.
Circumcision
Circumcision




Male circumcision is the
removal of some or all
of the foreskin
(prepuce) from the
penis.

the penis, in the shaft,
or applied as a cream.
The foreskin is pushed
from the head of the
penis and clamped with
a metal or plastic ringlike device.
