How is the male reproductive system different from other body systems?

it isn’t necessary to vital signs.

it monitors other body systems, and adjusts if necessary.

it transports items from one system to another.

it is the only system that produces hormones in the male.

The correct answer would be "It isn’t necessary to vital signs".

Vital signs refer to the set of signs or observations which provide the status about the life-sustaining ability of the body.

These signs include blood pressure, body temperature, breathing rate (respiratory rate), and pulse (heart rate).

These signs are not produced or determined by the male reproductive system.  

The main function of the male reproductive system is to produce, maintain, and transport sperm or semen.
