👉 Prothmia is a medical term that refers to the opening of the urethra (urinary system) in males and the urethral sphincter, which is an involuntary muscle located at the base of the penis, in females. This opening serves as a protective barrier against infection and also allows for urine flow. Prothmia can be caused by various conditions such as trauma or injury to the urethra, infections, and certain medications.
