Follicular Phase Flashcards
Chapter 8
follicular phase four main events
gnrh relase
folliculare growth
increase estrogen
estrus (heat)
ovulation
goes luoiseois
what are the primary steps that lead to preovulatory LH surge?
decrease of P4 from the CL
increase of GnRH
increase of FSH and LH
which leads to proestrual follicular development
(increase of inhabin = decrease of FSH)
(increase of estradiol = preovulorty LH surge )
what are the dynamics of antral follicules co
recruitment
selection
dominance
atresia
what does inhibin ?
attacks FSH
what are the major
what is responsible for the major high blood concentrations of estradiol in our blood ?
the surge center
true/false
GnRH secretion from the tonic center appears to be spontaneous but is influnced by progesterone
true
low progesterone = high GnRH
true/false
GnRH secretion from the surge center is controlled by low estradiol and high progesterone
false
high estradiol and low progesterone
present of oxytocin
pg2 alpha
True/ false
Atresia occurs continuously throughout folliculogenesis
True
What is the recruitment phase?
High fsh
Low LH pulses
Low inhibin
Low estradiol
