The main and obvious difference between the male and female urinary organs is that males have penises and females have vaginae. The male penis is a long urethra that protrudes out of the body, and the female urethra, which is the vagina, is an internal one. It is shorter than the male urethra. There are many reasons why both the systems are different from each other.
The male urethra has three parts to it, namely the prostatic urethra, membranous urethra, and spongy urethra. The urethra in males extends from the neck of the bladder to the meatus urinarius, which is present at the end of penis.
The male urethra it shaped like a tube, which has a transverse slit along its length. And, the upper and lower parts of the slit are in contact when the urethra is not expelling urine or semen.
Prostatic Urethra: The prostatic urethra starts from the neck of the urinary bladder, and passes through the prostrate gland. It is the broadest part of the male urethral canal which can also dilate the maximum.
Membranous Urethra: This is the shortest part of the male urethral canal, and measures approximately 0.5 to 0.7 inches. This part passes through the urogenital diaphragm
Unlike the female urethra, the male urethra has a dual role to play. It helps to expel the urine out of the body and is also important in reproductive function as it is responsible for carrying the semen out of the body when ejaculation takes place.
