Which of the following statements concerning menopause is correct?

Options

A. Menopause occurs because all of the female's follicles become hormone-producing corpus luteum at once.
B. Menopausal symptoms are a result of decrease in the production of FSH and LH.
C. The onset of menopause is primarly due to follicle atresia.
D. All of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Menopause:**
- Menopause is defined as the permanent cessation of menstruation in females. It typically occurs around the age of 50 years.

2. **Evaluating the Statements:**
- We need to analyze the provided statements regarding menopause to determine which one is correct.

3. **Analyzing Option 1:**
- Option 1 states that menopause occurs because all the female follicles become hormone-producing corpus luteum at once.
- This statement is incorrect because the corpus luteum is involved in the menstrual cycle and its degeneration leads to menstruation, not menopause.

4. **Analyzing Option 2:**
- Option 2 claims that menopausal symptoms are a result of decreased production of FSH and LH.
- This statement is also incorrect. In fact, during menopause, there is an increase in FSH (Follicle Stimulating Hormone) levels due to the decreased response of the ovaries.

5. **Analyzing Option 3:**
- Option 3 states that the onset of menopause is primarily due to follicle atresia.
- This statement is correct. Follicle atresia refers to the degeneration of ovarian follicles, and as these follicles degenerate, ovulation ceases, leading to the cessation of menstruation and thus menopause.

6. **Conclusion:**
- After evaluating all the options, we conclude that the correct statement regarding menopause is Option 3: the onset of menopause is primarily due to follicle atresia.
