Question

Hormone that maintain the integrity of the uterine wall during pregnancy is

• A. Estrogen
• B. Progesterone
• C. Oxytocin
• D. None of the above

Answer 1

Answer: (B)

Progesterone

Progesterone is the hormone which is secreted by the corpus luteum in the ovary. The hormone is responsible for the maintenance of pregnancy and hence, known as pregnancy hormone. The hormone helps in maintaining the thickness of the uterine cell lining throughout the phase of pregnancy. When the fertilisation of the egg does not take place, there is a decrease in the level of the hormone and the uterine cell lining sheds off and is released from the body.

Thus, the correct answer is option B.
