52. Which of the following would most directly cause reduced levels of estrogen production? an anterior pituitary tumor that increases secretion of FSH an increase in hypothalamus hormones that target the anterior pituitary anterior pituitary damage that prevents synthesis and release of FSH a decrease in hypothalamus hormones that target the anterior pituitary an anterior pituitary tumor that increases secretion of LH

Transcript

00:01 Hello everyone in this question we will be discussing about the regulation of the estrogen.

00:08 So the hypothalamus that is located centrally in the brain and communicates through the exchange of blood with the pituitary gland.

00:20 The several endocrine agents are produced by the hypothalamus and the most important hormone is the gonadotropin releasing hormone.

00:34 It stimulates the pituitary gland to produce follicle stimulating hormone.

00:42 The hormone that is responsible for starting follicle development and causing the level of estrogen that is the primary female hormone to rise.

00:56 The luteinizing hormone, the other reproductive pituitary hormone aids in egg maturation and provides the hormonal trigger to cause ovulation and the release of the eggs from the ovale.

01:11 As the follicles grow, the blood levels of estrogen rise significantly by the cycle day 7 and this increase of the estrogen begins to inhibit the secretion of follicle stimulating hormone and the fall in the follicle stimulating hormone allows smaller follicles to die off.

01:35 And then the level of estrogen is sufficiently high, it produces a sudden release of luteinizing hormone, usually around the day 13 of the cycle.

01:47 And a let's stimulates the estrogen and progesterum production from the ovary.

01:53 So here in the question we have been asked that which of the following would most directly cause reduced level of estrogen production.

02:03 So in option a we can see that it says an anterior pituitary tumor that increases the secretion of fsage.

02:12 So if fsage is increased, that means it will stimulate the production of estrogen.

02:18 And so this will be wrong...
