The female and male urethrae differ significantly in length, function, and anatomical placement.
Key Differences
- Length: The female urethra is much shorter, typically measuring 3 to 4.5 centimetres (about 1.5 inches), whereas the male urethra is significantly longer, reaching approximately 18 to 20 centimetres.12
- Function: The female urethra serves exclusively as a channel for urine and secretions from mucous glands. In contrast, the male urethra is a dual-purpose duct that conveys both urine and semen, as well as secretions from the prostate gland and other associated glands.12
- Anatomy and Location: The female urethra is embedded in the anterior wall of the vagina and opens between the labia minora. The male urethra is more complex, divided into three distinct segments—prostatic, membranous, and spongy—and traverses the length of the penis.12
Both structures are controlled by the sphincter urethrae, which regulates the flow of urine from the bladder.12
