Question: is there a difference between male and female catheters?
Answer: The length of a male urethra is around 18 to 20 cm. The length of a female urethra is around 3 to 4 cm. This means that a female catheter is much shorter than a male one. So a male catheter is approximately 30-40 cm long and a female catheter between 7 and 20 cm long.
