Question

Does the reproductive system maintain homeostais on its own, or does another system assist it?

Answer 1

It is assisted by other systems.

Explanation:

As a complex interconnected system, most homeostasis functions in the human body - including the reproductive one - rely on several other systems (hormones/endocrine, circulatory) to maintain the desired conditions.

The tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to stabilize health and functioning, regardless of the outside changing conditions.
