Options

A. low FSH, high LH and high estrogen
B. low FSH, high LH and low estrogen
C. high FSH, low LH and high estrogen
D. high FSH, high LH and high estrogen

Answer

To solve the question "Just prior to ovulation, there is:", we need to analyze the hormonal changes that occur in the menstrual cycle leading up to ovulation.

### Step-by-Step Solution:

1. **Understanding the Menstrual Cycle**: The menstrual cycle is typically around 28 days long and is divided into several phases: the follicular phase, ovulation, and the luteal phase. Ovulation occurs approximately in the middle of the cycle.

2. **Hormonal Changes**:
- **Follicle Stimulating Hormone (FSH)**: During the follicular phase, FSH is released from the anterior pituitary gland. It stimulates the growth of ovarian follicles.
- **Luteinizing Hormone (LH)**: As the follicles mature, they produce estrogen, which in turn stimulates a surge in LH just before ovulation.
- **Estrogen**: The developing follicles also secrete estrogen, which rises as the follicles grow.

3. **Just Prior to Ovulation**:
- As ovulation approaches, there is a significant increase in the levels of FSH, LH, and estrogen.
- This surge in hormones is crucial for triggering ovulation, which is the release of an egg from the ovary.

4. **Conclusion**: Therefore, just prior to ovulation, we observe high levels of FSH, high levels of LH, and high levels of estrogen.

5. **Choosing the Correct Option**: Based on the analysis, the correct answer is the option that states "high FSH, high LH, and high estrogen."

### Final Answer:
The correct answer is: high FSH, high LH, and high estrogen (4th option).
