During Proliferative Phase the Growing Follicles Secrete?

The follicular phase

follicular phase
The follicular phase, also known as the preovulatory phase or proliferative phase, is the phase of the estrous cycle (or, in primates for example (humans, monkey and great apes), the menstrual cycle) during which follicles in the ovary mature from primary follicle to a fully mature graafian follicle.

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 happening to the follicle during the proliferative phase?

While the ovaries are working on developing the egg-containing follicles, the uterus is responding to the estrogen produced by the follicles, rebuilding the lining that was just shed during the last period. This is called the proliferative phase because the endometrium (the lining of the uterus) becomes thicker.

What is secreted during proliferative phase?

At the end of the proliferative phase, 17-beta-estradiol levels are at a high due to the follicle maturation and increased production of the hormone. During this time only, 17-beta-estradiol provides positive feedback for FSH and LH production.
