What initiates follicle maturation?

At sexual maturity, two hormones, produced by the pituitary gland: follicle stimulating hormone (FSH) and lutenising hormone (LH) cause these primordial follicles to develop. In each ovarian cycle, about 20 primordial follicles are activated to begin maturation.

What stimulates follicle rupture?

The hormones that stimulate ovulation are produced in the pituitary gland; these are known as the follicle-stimulating hormone and luteinizing hormone.

What causes a mature follicle to rupture?

During ovulation, cellular chemicals called prostaglandins and proteolytic enzymes weaken the wall of the follicle containing the egg, resulting in a rupture through which the egg is released.

What is follicle maturation?

Follicular maturation and development is a complex process of interrelated intra- and extraovarian events that ultimately lead to ovulation of a mature oocyte and transformation of the ruptured follicle into a corpus luteum.

Which of the following hormones initiate of maturation of the follicles?

follicle stimulating hormone (FSH)
GnRH stimulates (causes) the pituitary gland to produce follicle stimulating hormone (FSH), the hormone responsible for starting follicle (egg) development and causing the level of estrogen (the primary female hormone) to rise.

How long free fluid remains after follicle rupture?

Once an egg is released from an ovary, it will die or dissolve within 12 to 24 hours if it’s not fertilized. If fertilization doesn’t occur, the egg and your uterine lining will shed.
