- **Estrogen**: This is a steroid hormone primarily involved in the regulation of the female reproductive system and secondary sexual characteristics.
- **Progesterone**: This is also a steroid hormone that plays a role in the menstrual cycle and pregnancy.
- **Testosterone**: This is a steroid hormone that is responsible for the development of male reproductive tissues and secondary sexual characteristics.

3. **Determine the Odd One Out**: From the classifications:
- FSH is a peptide hormone.
- Estrogen, Progesterone, and Testosterone are all steroid hormones.

4. **Conclusion**: Since FSH is the only hormone listed that is not a steroid hormone, the answer to the question is FSH.

### Final Answer:
