Chapter 28, Problem 15CP
Summary Introduction
To determine:
The effects of blockage of progesterone receptor in the uterus on the endometrium.
Introduction:
Uterus is the pear shaped organ that is responsible for the development of fetus. The main function of uterus is to provide mechanical protection to fetus, nutrition support to fetus and removal of waste. It consists of three layers perimetrium, myometrium and endometrium. Endometrium is the innermost functional layer of uterus that leads to menstruation.

Students have asked these similar questions
Shedding of the functional layer of the endometrium also known as menstruation occurs when
a) the concentration of LH in the blood peaks
b ) the corpus luteum degenerates and turns into corpus albican
c ) blood level of progesterone from the corpus luteum increases
e ) blood level of FSH falls off
Sloughing of the functional layer of the endometrium occurs because of:
A) Increasing estrogen
C ) Decreasing progesterone levels
D ) Increasing progesterone levels
If the ovum is not fertilized, the corpus luteum regresses, and the endometrium sloughs off to result in the first day of menstrual bleeding. The latter event would be duplicated, even if fertilization occurred, if receptors for which of the following hormones were occupied by an antagonist?
A) Dehydroepiandrosterone
B) Estradiol
C ) Estriol
D) Estrone
E) Progesterone
