The hormone responsible for puberty in males is ____

Options

A. Adrenaline
B. Testosterone
C. Oestrogen
D. Insulin

Answer

**Step-by-Step Solution:**

1. **Understanding Puberty**: Puberty is a developmental stage where individuals undergo physical and hormonal changes that lead to sexual maturity. In males, this process is primarily regulated by specific hormones.

2. **Identifying Male Hormones**: The male reproductive hormone, also known as a sex hormone, plays a crucial role during puberty.

3. **Role of Leydig Cells**: The hormone responsible for initiating and regulating these changes is secreted by Leydig cells, which are located in the testes.

4. **Evaluating Hormones**:
- **Adrenaline**: This hormone is involved in the fight-or-flight response and does not relate to male reproductive functions.
- **Testosterone**: This is the primary male sex hormone responsible for the development of male secondary sexual characteristics, such as increased muscle mass, deeper voice, and facial hair.
- **Estrogen**: This is primarily a female hormone and is not responsible for male puberty.
- **Insulin**: This hormone regulates blood sugar levels and is not related to sexual development.

5. **Conclusion**: Based on the evaluation, the hormone responsible for puberty in males is **testosterone**.

**Final Answer**: The hormone responsible for puberty in males is **testosterone**.
