2. **Review the Options**: The options provided are:
- A) Testosterone
- B) Gonadotropin

3. **Understand Male Hormones**: Male hormones, also known as androgens, are responsible for the development of male characteristics and the production of male gametes (sperms).

- **Option C: Progesterone**: This hormone is primarily involved in the female reproductive system, particularly in maintaining the endometrium during pregnancy.
- **Option D: Corpus Luteum**: This is not a hormone but a structure formed in the ovary after ovulation that produces hormones, including progesterone.
