The ruptured follicle turns into the corpus luteum. The hypothalamus releases GnRH. Negative feedback due to presence of inhibin leads to a decrease in FSH secretion. FSH stimulates secondary follicles to develop into tertiary follicles. Developing follicles secrete estrogen and inhibin.

Step 1

Step 1: The hypothalamus releases GnRH (gonadotropin-releasing hormone), which is the initial hormonal signal that starts the ovarian cycle. Show more…

00:01 The question talks about the ovarian cycle.

00:03 Ovarian cycle which also means menstrual cycle or the reproductive cycle in humans.

00:11 Now in ovarian cycle there are certain phases, some phases given and we have to arrange them.

00:17 So according to the ovarian cycle, the first event that will occur is the hypothalamus release.

00:24 So the hypothalamus in our brain is going to release gnrh.

00:34 Gnrh is the gonadotropin releasing hormone.

00:37 Once this hypothalamus releases the gnrh, this stimulates the anterior pituitary.

00:45 Once the anterior pituitary is stimulated, this in turn releases the fsh and the lh.

00:53 Fsh is these follicle stimulating hormone and lh is the eugenizing hormone.

00:59 Then the third event that is going to take place is the fsh is going to stimulate it is going to stimulate secondary follicle development.

01:16 This means that the secondary let's say if this is the secondary follicle this is going to get converted into tertiary follicle and finally into the graphene follicle graphene follicle so this is the development of fsh the fourth step will be that the developing follicles the developing follicles these follicles are going to release hormones such as estrogen and and inhibin hormone.

01:55 So the developing follicles, they are going to release the estrogen and inhibin hormones.

02:02 This estrogen is basically, this helps in the proliferation of the uterus.

02:07 Then the fifth point will be, now once the secondary development has, secondary follicle development has taken place into tertiary and then finally, the caffeine follicle, what happens is that the inhibin, which was secreted here, by the developing follicles this is going to send a negative feedback so a negative feedback is gonna be sent due to the presence due to presence of inhibin and once this feedback negative feedback is gone to the brain this will lead in the decrease of fsh secretion so decrease in fsh secretion.

02:59 So now my fsh secretion will decrease.

03:03 After this, the next event that is going to take place is the search...
