LH is produced as the result of
Correct answer: D. Both B and C
- A. Ovulation
- B. Decrease in FSH production
- C. Increase in estrogen level
- D. Both B and C
Explanation
Option A: Ovulation is the process of releasing a mature egg from the ovary. It usually occurs about 14 days before a woman's menstrual period starts. Ovulation is triggered by a surge in LH levels. Option D: LH (luteinizing hormone) is produced as a result of both an increase in estrogen level and a decrease in FSH production. Estrogen is a hormone that is produced in the ovaries. It helps to mature the eggs and prepare the ovaries for ovulation. When estrogen levels rise, it signals the pituitary gland to release LH. LH then causes the ovaries to release a mature egg. FSH (follicle-stimulating hormone) is another hormone that is produced by the pituitary gland. It helps to stimulate the growth and development of eggs in the ovaries. When FSH levels decrease, it signals the pituitary gland to release more LH. This increase in LH then triggers ovulation. Therefore, the answer to the question is Both B and C.

About Menstrual Cycle
The menstrual cycle covers the coordinated changes in the ovaries and uterus, including menstruation, follicular growth, ovulation and corpus luteum formation. It links follicle-stimulating hormone, luteinizing hormone, oestrogen and progesterone with endometrial changes, and distinguishes the ovarian cycle from the uterine cycle and the hormonal events of pregnancy.
