Question: 1 / 530

Which of the following hormones does NOT play a role in collagen production?

Estrogen

Testosterone

Cortisol

Cortisol does not play a direct role in collagen production compared to the other hormones mentioned. While collagen is a crucial protein that provides structure and support to various tissues in the body, the hormones estrogen, testosterone, and insulin have more significant influences on the processes that support collagen synthesis.

Estrogen, for instance, is known to enhance collagen production, improve skin elasticity, and promote hydration, all of which contribute to the overall health and appearance of the skin. Testosterone plays a role in maintaining muscle and tissue integrity, which includes supporting collagen levels. Insulin is important for general metabolism and can influence the uptake of nutrients necessary for collagen synthesis.

Cortisol, on the other hand, is a glucocorticoid hormone typically associated with stress response and regulation of metabolism. Elevated levels of cortisol can actually lead to the breakdown of collagen and may inhibit the synthesis of new collagen. This catabolic effect is particularly evident in chronic stress situations where prolonged elevated cortisol levels can adversely affect skin health and elasticity.

Therefore, while other hormones contribute positively to collagen production, cortisol does not support this process and, in fact, can detract from the body's collagen levels.
