Answer

To answer the question "Which hormone is produced throughout a menstrual cycle?" we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Menstrual Cycle**: The menstrual cycle in human females typically lasts about 28 days and involves various hormonal changes.

2. **Identify Key Hormones**: There are four main hormones involved in the menstrual cycle:
- Follicle Stimulating Hormone (FSH)
- Luteinizing Hormone (LH)
- Estrogen (specifically Estradiol)
- Progesterone

3. **Role of Each Hormone**:
- **FSH**: Secreted by the anterior pituitary gland, it stimulates the maturation of ovarian follicles.
- **LH**: Also secreted by the anterior pituitary gland, it triggers ovulation and supports the formation of the corpus luteum.
- **Estrogen**: Produced by the developing follicles, it is crucial for the thickening of the endometrium.
- **Progesterone**: Secreted by the corpus luteum after ovulation, it prepares the endometrium for potential implantation of an embryo.

4. **Determine Which Hormone is Produced Throughout the Cycle**:
- FSH and LH are primarily active during specific phases of the cycle (FSH during follicular phase and LH during ovulation).
- Estrogen is produced mainly during the follicular phase and peaks just before ovulation.
- Progesterone is produced after ovulation during the luteal phase.

5. **Conclusion**: Among these hormones, **Estrogen** is the one that is produced throughout the menstrual cycle, albeit in varying amounts.

### Final Answer:
The hormone produced throughout a menstrual cycle is **Estrogen**.
