The function of the cremaster muscle is to
elevate the testes during sexual arousal and exposure to cold
generate peristaltic waves in the ductus deferens
control the release of secretions from the seminal vesicles
control the release of sperm cells from the testes into the epididymis
Leydig cells are located
in all the male accessory reproductive organs
interspersed among developing sperm cells in seminiferous tubules
lining the epididymis and ductus deferens
in spaces between adjacent seminiferous tubules
The process of crossing-over, or recombination, of genes occurs during
meiosis I
meiosis II

spermiation
The function of fructose in semen is to
provide an energy source for ATP production by sperm
promote coagulation of semen in the female reproductive tract
buffer acids in the female reproductive tract
inhibit the growth of bacteria in semen and the female reproductive tract
The seminal vesicles are located
inferior to the prostate within the urogenital diaphragm
within the lobules of the testes
within the spermatic cord
posterior and inferior to the urinary bladder, in front of the rectum
Which of the following does NOT manufacture products that become part of semen?
seminiferous tubules
bulbourethral glands
penis
seminal vesicles
The amount of testosterone in the blood is increased by
a high level of testosterone stimulating the hypothalamus
the hypothalamus stimulating the testes to release LH
LH causing the interstitial cells to release testosterone
a high level of testosterone stimulating the testes to release more LH
If the testes fail to descend, a male is infertile because sperm cell formation is prevented by
relatively high internal body temperature
excessive production of estrogen
lack of testosterone
None of the above
The hormone responsible for the development and maintenance of male secondary sexual characteristics is
ICSH
FSH
testosterone
gonadotropin-releasing hormone
Male reproductive functions are controlled mainly by hormones from the hypothalamus
posterior pituitary and adrenal glands
anterior pituitary and adrenal glands
posterior pituitary gland and testes
anterior pituitary gland and testes
The interstitial cells of the testes produce
seminal fluid

testosterone
Maintenance of the male secondary sex characteristics is the direct responsibility of
estrogen
testosterone
FSH
progesterone
A function of FSH in the male is to
inhibit progesterone
initiate testosterone production
increase protein synthesis
initiate spermatogenesis
In the male, LH causes
initiation of spermatogenesis
development of secondary sex characteristics
testosterone production
ejaculation
Egg cells are transported in the female reproductive tract by the ____, whereas sperm are transported in the male reproductive tract by the _____.
action of ciliated epithelium in the uterine tubes; movements of their tails
activity of seminal vesicle secretion; activity of prostate gland secretions
peristaltic contractions of the vaginal wall; peristaltic contractions of the uterus
movement of their tails; lashing movements of their tails
The first step in oogenesis is a
secondary oocyte divides to form a polar body and an egg cell
primary oocyte divides to form a secondary oocyte and a first polar body
follicle is converted to a corpus luteum
corpus luteum is converted to a corpus albicans
The cell commonly called the egg, or ovum, is more correctly called a(n)
primary oocyte
secondary oocyte
oogonium
zygote

ostium uteri
cervix
perimetrium
endometrium
The female structure that contains erectile tissue like the male penis is the
vagina
clitoris
vestibule
labia minora
The first meiotic division in oogenesis occurs
before ovulation
only if the egg is fertilized
after ovulation
monthly after puberty in response to FSH and LH
The female structure that is homologous to the testis is the
ovary
uterus
vagina
clitoris
The uterus is located between the
urinary bladder and the pubic symphysis
rectum and the sacrum
urinary bladder and the rectum
kidneys in the same horizontal plane
The epithelium of the vaginal mucosa is
simple squamous
simple cuboidal
simple columnar
stratified squamous
The hormone commonly measured in a pregnancy test is
estrogen
progesterone
HCG
ADH
The hormone oxytocin aids the birth process by stimulating
fetal muscular movements
uterine wall contractions
an increase in progesterone secretion
an increase in estrogen secretion
During the menstrual cycle, LH is at its highest levels
during the menstrual phase
just prior to ovulation
just after ovulation
just before menstruation begins
