starts with the first day of your period and ends with ovulation. The follicular phase is also known as the “proliferative phase” because rising estradiol (estrogen) levels cause the endometrial lining of the uterus to proliferate and thicken.

What is the proliferative phase also known as?

The follicular phase of the female menstrual cycle includes the maturation of ovarian follicles to prepare one of them for release during ovulation. During the same period, there are concurrent changes in the endometrium, which is why the follicular phase is also known as the proliferative phase.

Why is luteal phase called secretory phase?

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. Only higher primates have menstrual cycles with regular bleeding.
