Both FSH and LH
secretion by the
anterior pituitary
increases, with FSH
increase being slightly
greater than LH
-LH stimulates the granulosa cells and theca cells
to be converted to luteal cells → Corpus luteum
-Progesterone: Stimulate the uterine
endometrium to become secretory and produce a
source of nutrient for the developing blastocyst.
Stimulate the cervical mucus to become thick:
prevent entry of sperm and bacteria Causes
basal body temperature to rise slightly.
If no implantation occurs,
the low levels of FSH and
LH causes the corpus
luteum to degenerate
Degeneration → decrease
release of estrogen and
progesterone Decreased
stimulation of the
endometrial cells by these
two hormones
