Question

Hormone predominately secreted after 14 day on endometrium is?

• A. Progesterone
• B. Estrogen
• C. LH
• D. FSH

Answer 1

The Correct Option is A

In the menstrual cycle, the endometrium undergoes significant changes, influenced by various hormones. Around day 14, ovulation typically occurs, and following this, the luteal phase begins. During the luteal phase, which spans from ovulation until the start of menstruation, the hormone progesterone predominates.

This phase is characterized by the corpus luteum's secretion of progesterone. The primary role of progesterone during this phase is to maintain and prepare the endometrium for a potential pregnancy. It causes the endometrial lining to thicken and become suitable for implantation of a fertilized egg. If fertilization does not occur, progesterone levels will decrease, leading to the shedding of the endometrial lining, known as menstruation.

Given this information, the hormone predominantly secreted after day 14 of the menstrual cycle is:

Progesterone
