Meatus of the male penis

The urinary /ˈjʊərɨnˌɛri/, /ˈjʊərɨnri/ meatus /mˈtəs/ is an orifice or meatus of the urethra. It is the point at which urine and, in males, semen exits the urethra. The meatus features varying degrees of sensitivity to the touch. The meatus is located on the glans penis in males and in the vulval vestibule in females.

Males[edit]

In most males the meatus meets at the junction of the glans and the frenular delta, and continues in a longitudal pattern along the ventral aspect of the glans, which facilitates flow of urine during normal urination (micturition). The meatus is sensitive and is used in sexual intercourse. It is part of the male reproductive system.

Due to the fact that the penis is flexible and the urethral orifice therefore can be used to aim the urine stream in males, different positions in which males urinate are found globally. Some males prefer to urinate standing while other prefer to urinate sitting or squatting. Elderly males with prostate problems may benefit from sitting down while in healthy males, no difference is found in the ability to urinate.[1][2] For practising Muslim men, the genital modesty of squatting is also associated with proper cleanliness requirements or awra.[3]

Females[edit]

In females, the meatus is located between the clitoris and the vagina in the vulvular vestibule of the female genitalia. This part is also part of the female reproductive system. More specifically, it can refer to:

Disorders[edit]

Disorders of the meatus include epispadias, hypospadias, and urethral blockage by virtue of foreign material, kidney or bladder stones (lithiasis), or deformity, which can cause total or partial urinary blockage, or bifurcation of urine stream.
