What hormone(s) is responsible for thickening the lining of the uterus?
A
Oestrogen
B
progesterone
C
FSH & LH
D
LH only
Explanation: 

Detailed explanation-1: -Estrogen causes the lining to grow and thicken to prepare the uterus for pregnancy. In the middle of the cycle, an egg is released from one of the ovaries (ovulation). Following ovulation, levels of another hormone called progesterone begin to increase.

Detailed explanation-2: -During ovulation, estrogen thickens the endometrium, while progesterone prepares the uterus for pregnancy. If conception doesn’t occur, progesterone levels drop. The progesterone drop triggers the uterus to shed its lining as a menstrual period.

Detailed explanation-3: -Two hormones produced from the ovaries thicken and prepare the uterine lining for implantation. Estrogen causes the thin uterine lining to thicken. Progesterone causes the thickened uterine lining to develop the characteristics needed for implantation.

Detailed explanation-4: -The present observation shows that estrogen stimulates uterine peristalsis and is able to generate a cervico-fundal direction of peristalsis, whereas progesterone inhibits directed uterine peristalsis.

Detailed explanation-5: -Estrogen plays a role in ovulation (when your ovaries release an egg) and thickens the lining of your uterus (endometrium) to prepare it for pregnancy.
