The next phase of the menstrual cycle is the luteal or secretory phase. This phase always occurs from day 14 to day 28 of the cycle. Progesterone stimulated by LH is the dominant hormone during this phase
to prepare the corpus luteum and the endometrium for possible fertilized ovum implantation.
What does secretory phase mean?
Definitions of secretory phase.
the second half of the menstrual cycle after ovulation
; the corpus luteum secretes progesterone which prepares the endometrium for the implantation of an embryo; if fertilization does not occur then menstrual flow begins. synonyms: luteal phase.

the epithelial cells become hypersecretory and provide the necessary nutrition for the embryo and placenta's survival if implantation occurs
. Endometrial stromal cells also increase during the secretory phase.
What phase of menstrual cycle is secretory?
The luteal phase
is also referred to as the ‘secretory phase'. This refers both to the secretion of progesterone from the corpus luteum and to the secretion of a clear fluid by the endometrium during this phase.
