Menstrual cycle: First day of cycle is?	first day of menstruation
Follicular phase: due to high FSH, a few ovarian follicles mature -----> ______ follicle	gaafian
Follicular phase: ______ suppresses release of LH from the anterior pituitary gland	Estradiol
Mature egg is released from ovarian follicles day 14 does not vary	Ovulation
Ovulation: Estradiol reach its peak level causing, reversed effect, stimulates the production of a _________ - starts around day 12 of the average cycle and may last 48 hours.	a large amount of LH (called LH surge)
Ovulation: Large amount of LH causes?, causing it to release its egg cell	maturation of the egg and weakens the wall of the Graafian follicle, causing...
Ovulation: The process sometimes causes ovulation characteristic pain called ______ (German term meaning middle pain)	mittelschmerz
After being released from the ovary, the egg is swept into the fallopian tube by the?	fimbria
If it is not fertilized by a sperm = egg cell will?	degenerate in 24 hours
If it is fertilized by a sperm = ???	pregnancy
Fertilization occurs usually in the?	ampulla
Which of the two ovaries ovulates = ???	random
If both ovaries releases eggs and are fertilized = ???	fraternal twins
If only one ovary releases eggs and split = ???	identical twins
A fertilized egg immediately begins the process of ???	embryogenesis
The developing embryo takes about ??? to reach the uterus and another ____ to implant into the endometrium	3 days to reach the uterus and another 3 days to implant into the endometrium
During implantation, some women experiences?	implantation bleeding
Start of ovulation to end of cycle	Luteal Phase (15-28) days
Luteal Phase (15-28) days: FSH & LH cause dominant follicle to transform into ____	corpus luteum
Luteal Phase (15-28) days: Corpus luteum produces	progesterone
Luteal Phase (15-28) days: high levels of progesterone induce the production of _____ and suppress production of the _____ and _____.	... induce the production of estrogen and suppress production of the FSH and LH
Luteal Phase (15-28) days: FSH and LH maintains the	corpus luteum
Luteal Phase (15-28) days: When the level of FSH and LH drop quickly over time the corpus luteum subsequently atrophies into _____	Corpus albicans
Luteal Phase (15-28) days: When corpus luteum atrophies, progesterone level _____	decreases
Luteal Phase (15-28) days: Decreased level of Progesterone trigger ???	menstruation and the beginning of the next cycle
Luteal Phase (15-28) days: From the time of ovulation until progesterone withdrawal has caused menstruation to begin, the process typically takes about?	two weeks, with 14 days considered normal.
if fertilization occurs, the loss of the corpus luteum is prevented by?	Fertilization of the egg
the ____, which is the outer layer of the resulting embryo-containing structure (the blastocyst) and later also becomes the? produces HCG (Human Chrionic Gonadotrophin)	outer layer of the placenta
HCG is very similar to LH because?	it preserves the corpus luteum
The corpus luteum can then continue to secrete progesterone to?	maintain the pregnancy.
Most pregnancy tests look for the presence of	hCG
