So this question runs us through several different types of hormones and asks us to figure out which one is not a function of that hormone.
00:09
We have in this question, estrogen and progesterone, which are given together, lutonizing hormone, or lh, and human corionic gonadotropic, or hcg.
00:21
So let's review each one and see where they come from and what their function is, and then we'll see which of our answer choices is incorrect.
00:29
So let's start out with estrogen and estrogen.
00:31
These are two hormones that are primarily produced within follicle cells, which are the cells that surround the primary oocyte within the ovaries.
00:44
And these hormones are related to basically controlling when the oocyte develops further and when the egg itself is released.
00:58
And there are two different possibilities here.
01:02
Happens if the oocyte develops and becomes an ovum and then that egg cell is ovulated, then the follicle cells will develop into the corpus luteum, and these continue to produce estrogen and progesterone.
01:20
However, if the egg is not ovulated, then the follicle cells still turn into this corpus luteum, and so it begins releasing estrogen and progesterone, but after time, this disintegrates.
01:37
And that begins the sort of first hormonal stages of menstruation.
01:45
So that is our sort of first set of hormones.
01:49
Next step, we have lutenizing hormone, or lh...
