Anhidrosis is the inability to sweat normally. If the human body cannot sweat properly, it cannot cool itself, which is potentially harmful.

Anhidrosis most directly interferes with:

• a feedback mechanism that maintains homeostasis

• an immune system response to harmless antigens

• the synthesis of hormones in the circulatory system

• the enzymatic breakdown of water in cells

Testosterone directly affects the

• formation of a zygote
• changes within an ovary
•  production of sperm cells
• development of a placenta
