1. The role of the urinary system in sexual relations

The urinary system’s function is to eliminate liquid waste from the body and maintain proper chemical balance. However, during sexual intercourse, especially in women, the urethra (the tube through which urine exits the body) can be exposed to bacteria from the skin, genitals, or even the anal area.

Something similar happens in men, although less frequently due to the length of the male urethra. Even so, during sexual intercourse, microorganisms can enter the urethra and temporarily reside there. When urination doesn’t occur afterward, these bacteria have the perfect opportunity to multiply and cause urinary tract infections or inflammation.
