Explanation

To determine which statement about oocytes is true, we can analyze the provided statements step by step.

### Step-by-Step Solution:

1. **Understanding Oocyte Production**:
- Oocytes are the female gametes involved in reproduction. They are produced in the ovaries.

2. **Evaluating the First Statement**:
- The first statement claims that at the onset of menopause, the human female stops producing oocytes.
- This statement is misleading. While it is true that the production of new oocytes ceases, it is important to note that females are born with a finite number of oocytes, and they do not produce new ones after birth.

3. **Evaluating the Second Statement**:
- The second statement suggests that at birth, the female has produced all the oocytes she will ever produce.
- This statement is accurate. Females are born with all the oocytes they will have in their lifetime, and no new oocytes are produced after birth.

4. **Evaluating the Third Statement**:
- The third statement mentions that oocytes are stored in the seminiferous tubules.
- This statement is incorrect. Seminiferous tubules are found in males and are involved in sperm production, not oocyte storage.

5. **Conclusion**:
- After evaluating all the statements, the true statement about oocytes is that at birth, the female has produced all the oocytes she will ever produce.

### Final Answer:
The true statement about oocytes is: "At birth, the female has produced all the oocytes she will ever produce."
