Luteal Phase, Uterus, Mammary Glands, Hypothalamus, brain (cortex), LH # -…
Luteal Phase
follicle ruptures at ovulation
collapses & becomes folded
thecal & granulosal cells mix
luteinization (become luteal tissue)
granulosal cells become
large luteal cells
hypertrophy
secrete
progesterone
#

#
#
oxytocin
#
thecal cells become
small luteal cells
hyperplasia
secrete
progesterone

Uterus
endometrium
progesterone
stimulates max secretion from glands
supports development of embryo after it arrives in uterus
oxytocin
causes endometrium to produce PGF2-alpha in pulses
increases oxytocin release by large luteal cells
increases frequency of PGF2-alpha secretion
luteolysis
cessation of progesterone secretion
GnRH no longer inhibited
proestrus initiates
CL becomes corpus albicans
myometrium
reduces contractions (except in mare)
allows the attachment of conceptus to endometrium
Mammary Glands
final alveolar devolopment
Hypothalamus
reduced GnRH pulse frequency by tonic center
reduced frequency of FSH & LH secretion by pituitary
LH & FSH allow for follicles to develop during luteal phase; progesterone prevents GnRH surge & estrus
brain (cortex)
primed by progesterone to respond to estrogen during estrus
amplifies intensity & duration of mating behaviors
LH
