Which of the following is a male hormone?

1. Estrogen

2. Progesterone

3. Testosterone

4. Insulin

The correct answer is: Testosterone

Testosterone is widely recognized as a male hormone because it plays a crucial role in the development of male reproductive tissues, such as the testes and prostate, as well as promoting secondary sexual characteristics like increased muscle and bone mass, and the growth of body hair. While testosterone is present in both males and females, it is typically found in higher levels in males, which is why it is commonly referred to in the context of male physiology. The other hormones listed serve different functions and are typically categorized based on their roles in the female reproductive system or metabolic processes rather than in male development. Estrogen and progesterone are predominantly female hormones that regulate female reproductive functions, while insulin is a hormone that regulates glucose levels in the blood, unrelated to male or female reproductive characteristics. Understanding these distinctions helps clarify why testosterone is specifically recognized as a male hormone.
