The Nursing Role in Reproductive and Sexual Health Flashcards
is a body organ that produces the cells necessary
for reproduction
gonad
Reproductive development begins ________________________________ and continues through life
at the moment of conception
A gonad is a body organ that produces the cells necessary
for reproduction (the ______________ in females, the _______________ in males)
ovary; testis
At approximately _____________ of intrauterine life, _______________________________________, the tissue that will become ovaries and testes, have already formed.
week 5; mesonephric (wolffian) and paramesonephric (müllerian) ducts
By _________________, in chromosomal males, this early gonadal tissue begins formation of ____________________. Under the influence of testosterone, the ____________________ develops into __________________________ and the ______________________________ regresses. If testosterone is not present by ____________, the ___________________________becomes dominant and develops into ____________________________
week 7 or 8; testosterone; mesonephric duct; male reproductive organs; paramesonephric duct; week 10; paramesonephric duct; female reproductive organs.
cells that will develop into eggs throughout the woman’s mature years
oocytes
At about _____________ of intrauterine life, the external genitals
begin to develop.
week 12
These changes in girls are stimulated when the _____________________ synthesizes and releases ____________________________, which then triggers the ____________________ to release __________________________________ and ___________________________________. FSH and LH are termed gonadotropin (gonad “ovary”; tropin “growth”) hormones not only because they begin the production of androgen and estrogen, which in turn initiate secondary sex characteristics, but also because they continue to cause the production of eggs and influence menstrual cycles throughout women’s lives
hypothalamus; gonadotropin-releasing hormone (GnRH); anterior pituitary; follicle-stimulating hormone (FSH); luteinizing hormone (LH)
FSH and LH are termed
gonadotropin (gonad “ovary”; tropin “growth”) hormones
they begin the production of androgen and estrogen, which in turn initiate secondary sex characteristics
FSH and LH/ gonadotropin hormones
they continue to cause the production of eggs and influence menstrual cycles throughout women’s lives
FSH and LH/ gonadotropin hormones
the __________________ apparently serves as a gonadostat or regulation mechanism to
“turn on” gonad functioning.
hypothalamus
Although it is not proven, the general consensus is a girl must reach a critical weight of approximately ________________ or develop a critical mass of body fat before the hypothalamus is triggered to send initial stimulation to the anterior pituitary gland to begin the
formation of FSH and LH.
95 lb (43 kg)
are the hormones responsible for muscular development, physical growth, and the increase in sebaceous gland secretions that cause typical acne in both
boys and girls during adolescence.
Androgenic hormones
In males, androgenic hormones are produced by the __________________ and the ________
adrenal cortex; testes
In females, androgenic hormones are produced by the adrenal cortex and the ovaries
adrenal cortex; ovaries
closure of growth plates in long bones
adrenarche
When triggered at puberty by FSH, ovarian follicles in females begin to excrete a high level of the hormone __________________________
estrogen
The beginning of breast development is termed _________________ , which usually starts ________________________________
thelarche; 1 to 2 years before menstruation.
the first menstrual period
menarche
The average age at which menarche (the fi rst menstrual
period) occurs is _______________ of age
12.4 years
The study of the female reproductive organs is _____________________
gynecology
______________________ is the study of the male reproductive organs.
Andrology
External genital organs of the male include the ______________ and the __________
testes; penis
is a rugated, skin-covered, muscular pouch suspended from the perineum
scrotum
function of testes
to support the testes and help regulate the temperature of
sperm
are two ovoid glands, 2 to 3 cm wide, that rest in the scrotum
testes
Each testis is encased by a protective white fibrous capsule and is composed of a number of lobules. Each lobule contains ______________________ that produce _________________ and a ___________________ that produces _____________________.
interstitial cells (Leydig cells); testosterone; seminiferous tubule; spermatozoa
Testes that remain in the pelvic cavity
cryptorchidism
FSH in men is responsible for the release of
androgen-binding protein (ABP)
Although spermatozoa are produced in the testes, they reach maturity through a complex sequence of events. First,
the ____________________ releases _________, which in turn influences the ___________________ to release FSH and LH, the same as in women. FSH in men is responsible for the release of androgen-binding protein (ABP). LH is responsible for the release of testosterone from the testes. __________________ then combine to promote sperm formation. When the production of testosterone reaches a peak amount, a feedback effect on the hypothalamus and anterior pituitary gland is created, which slows the production of FSH and LH and ultimately decreases or regulates sperm production.
hypothalamus; GnRH; anterior pituitary gland; ABP and testosterone
is composed of three cylindrical masses of erectile tissue in the penis shaft
penis
At the distal end of the organ (penis) is a bulging, sensitive ridge of tissue called the ___________
glans
A retractable casing of skin, the ______________, protects the nerve-sensitive glans at birth.
prepuce
The male internal reproductive organs are the
epididymis, the vas deferens, the seminal vesicles, the ejaculatory ducts, the prostate gland, the urethra, and the bulbourethral glands
is responsible for conducting sperm from the tubule to the vas deferens
epididymis
absence of sperm
aspermia
fewer than 20 million sperm per milliliter
oligospermia
semen, or seminal fluid that contains a basic ________ and __________
sugar; protein
is an additional hollow tube surrounded by arteries and veins and protected by a thick fi brous coating
vas deferens
The vas deferens is an additional hollow tube surrounded by arteries and veins and protected by a thick fi brous coating, which, altogether, are referred to as the ________________
spermatic cord
severing of the vas deferens to prevent passage of sperm
vasectomy
are two convoluted pouches that lie along the lower portion of the bladder and empty into the urethra by ejaculatory ducts.
seminal vesicles
These glands secrete a viscous alkaline liquid with a high sugar, protein, and prostaglandin content.
seminal vesicles
seminal vesicles secrete a viscous alkaline liquid with a high ________________________________________ content
sugar, protein, and prostaglandin
is a chestnut-sized gland that lies just below the bladder and allows the urethra to pass through the center of it, like the hole in a doughnut
prostate
The gland’s purpose is to secrete a thin, alkaline fl uid, which, when added to the secretion from the seminal vesicles, further protects sperm by increasing the naturally low pH level of the urethra.
prostate gland
lie beside the prostate gland and empty by short ducts into the urethra
Bulbourethral Glands/Cowper’s glands
Semen, therefore, is derived from the _____________________________________________
prostate gland (60%), the seminal vesicles (30%), the epididymis (5%), and the bulbourethral glands (5%)
is a hollow tube leading from the base of the bladder, which, after passing through the prostate gland, continues to the outside through the shaft and glans of the penis.
urethra
structures that form the female external genitalia are
termed the _________
vulva
is a pad of adipose tissue located over the symphysis pubis
mons veneris
purpose of mons veneris
to protect the junction of the pubic bone from trauma
Just posterior to the mons veneris spread two hairless folds of connective tissue, the _______________
labia minora
are two folds of tissue, fused anteriorly but separated posteriorly, which are positioned lateral to the labia minora and composed of loose connective tissue covered by epithelium and pubic hair
labia majora
is the flattened, smooth surface inside the labia
vestibule
is a small (approximately 1 to 2 cm), rounded organ of erectile tissue at the forward junction of the labia minora
