prostatic urethra via several ducts
↓ levels of estrogens & progesterone Correct Answers may
alter female secondary sex characteristics; Breasts, uterus, &
uterine tubes may shrink, while pubic & axillary hair may thin;
Bone density may ↓ & ↑s risk of developing osteoporosis;
Vasomotor signs that include "hot flashes" may occur due to
changes in rhythmic secretion of GnRH by hypothalamus in
response to decreasing blood levels of sex hormones; may
experience many other nonspecific symptoms, including

,15-30 mins post-ejaculation Correct Answers >semen clot
breaks ↑ due to activity of PSA & other anticoagulants from
prostate
>Sperm cells are gradually released from clot, activated, &
begin their ascent up female reproductive tract
1st polar body Correct Answers >Smaller 1n cell contains
DNA but *little* cytoplasm → called __________ that usually
degenerates
>occasionally proceeds thru 2nd meiotic division forms 2 polar
bodies, *both of which degenerate*
3 Correct Answers Uterine cycle proceeds thru ___ phases
during an avg of 28 days
5 mins post-ejaculation Correct Answers semen coagulates due
to activities of clotting proteins from seminal vesicles &
enzymes from prostate → prevents semen from leaking out of

metabolized by bacteria → generates *lactic acid* that helps
maintain ___________ of this region
acrosome Correct Answers develops & covers nucleus & helps
with fertilization of female gametes by releasing digestive
enzymes
After puberty Correct Answers reproductive cycles continue @
regular intervals until 4th or 5th decade when they become
irregular
Aging Effects Correct Answers >Size & weight of testes may ↓
>Number of sustentacular & interstitial cells may ↓
Alleles Correct Answers different variants of the same gene
ampulla Correct Answers Uterine tubes move the oocyte from
*fimbriae* to the *______*; a saclike structure where ductus
deferens terminates

granulosa cells project into ________ (a single large cavity) on a
stalk
apoptosis Correct Answers Most primordial follicles have died
thru this process; programmed cellular death
Associated w/↓'d levels of testosterone Correct Answers
