The hormone predominantly secreted after the 14th day acting on the endometrium is?
Show Hint
After ovulation the corpus luteum secretes the hormone that drives the secretory endometrium.
Updated On: Jun 23, 2026
- Progesterone
- Estrogen
- LH
- FSH
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Anchor the timeline. In a standard cycle, day 14 is ovulation day, so everything after it falls in the luteal half of the cycle.
Step 2: Once the egg is released, the leftover follicle transforms into the corpus luteum. Its signature product is progesterone, which converts the already-thickened lining into a secretory, nutrient-rich bed ready for implantation. Progesterone output climbs and reaches its high point near day 21.
Step 3: Before ovulation, estrogen was the star, building up the proliferative endometrium. After day 14 that role hands over to progesterone, so estrogen is the wrong pick for the post-ovulatory endometrial effect.
Step 4: The gonadotropins LH and FSH act on the ovary rather than directly on the uterine lining; LH peaks to cause ovulation and FSH ripens follicles early on. The endometrial driver after day 14 is progesterone. \[\boxed{\text{Progesterone}}\]
