â—» stimulates follicle cells to release â—» and estrogen. This estrogen is critical to stimulating follicle development.
The female reproductive cycle starts when the hypothalamus releases â—» which stimulates the anterior pituitary to release â—» and LH.
In each cycle, a few primary follicles will start to mature, of which one will eventually become a mature follicle that will develop into a corpus luteum.
As cells multiply, a fluid-filled cavity starts to appear between the inner and outer layers of the follicle cells. This marks the formation of a secondary follicle.
5 â—» selectively inhibits the secretion of â—» from the anterior pituitary, which prevents the development of additional follicles.
As this fluid-filled space is formed, the developing follicle continues to secrete low levels of estrogen and progesterone. It also begins secreting luteinizing hormone.
â—» stimulates completion of meiosis I, yielding a secondary oocyte and polar body. â—» also stimulates ovulation, with release of the secondary oocyte.
â—» peaks on day 12 of a 28-day cycle leading to increased anterior pituitary release of â—».
FSH stimulates follicle cells to release progesterone and estrogen. This estrogen is critical to stimulating follicle development.
The female reproductive cycle starts when the hypothalamus releases GnRH, which stimulates the anterior pituitary to release FSH and LH.
In each cycle, a few primary follicles will start to mature, of which one will eventually become a mature follicle that will develop into a corpus luteum.
As cells multiply, a fluid-filled cavity starts to appear between the inner and outer layers of the follicle cells. This marks the formation of a secondary follicle.
Luteinizing hormone-releasing hormone (LHRH) selectively inhibits the secretion of FSH from the anterior pituitary, which prevents the development of additional follicles.
As this fluid-filled space is formed, the developing follicle continues to secrete low levels of estrogen and progesterone. It also begins secreting luteinizing hormone.
Luteinizing hormone stimulates completion of meiosis I, yielding a secondary oocyte and polar body. Luteinizing hormone also stimulates ovulation, with release of the secondary oocyte.
Luteinizing hormone peaks on day 12 of a 28-day cycle leading to increased anterior pituitary release of FSH.
