What is the male hormone that influences the production of sebum?

1. Estrogen

2. Testosterone

3. Androgen

4. Progesterone

The correct answer is: Androgen

The hormone that primarily influences the production of sebum is androgen, which is a category that includes hormones such as testosterone. Androgens are responsible for the development of male characteristics and also play a significant role in regulating sebum production in the skin. Sebum, an oily substance produced by sebaceous glands, helps to keep the skin moisturized and protected. Testosterone, while indeed an androgen, is specifically one type of male hormone within the broader category. Therefore, while testosterone contributes to sebum production, the term "androgen" encompasses all hormones with similar effects, including not only testosterone but also other related hormones that can influence sebaceous gland activity. Estrogen and progesterone, on the other hand, are primarily female hormones that do not significantly influence sebum production in the same way that androgens do. By understanding the role of androgens, you can better grasp the hormonal influences on skin conditions, particularly those related to oiliness and acne.
