virtsasuihkusta

Virtsasuihku, also known as a urine spray or urine jet, refers to the forceful expulsion of urine from the urethra. This phenomenon occurs naturally during urination in both males and females, though the mechanics and visual appearance can differ. In males, the penis and the musculature of the pelvic floor contribute to the pressure and direction of the urine stream. In females, the anatomy of the urinary tract, including the bladder and urethra, also results in a stream of urine.

The velocity and trajectory of the urine stream are influenced by factors such as bladder pressure, the degree of urethral constriction, and posture. These can vary from person to person and even from one urination event to another. While the term "virtsasuihku" typically describes the normal process of urination, in some contexts, it might be used to describe unusual or particularly forceful streams. Medical conditions or anatomical variations could potentially affect the way urine is expelled.
