Squirting should be distinguished from urinary incontinence — the latter may cause urine loss during sexual intercourse then referred to as coital incontinence but is a different phenomenon. The amount of expelled liquid in squirting can be up to several hundreds of milliliters. Five women between 30 and 60 years old and able to squirt participated, on a voluntary basis, in the study of Inoue and colleagues. Before sexual stimulation, a urethral catheter was inserted into the bladder. The bladder was then emptied, after which a blue dye was injected. Sexual stimulation was done manually by the participant in 3 cases or through sexual intercourse with a male sex partner in 2 cases. All women confirmed that they did not have a sensation of urinary incontinence during squirting. The researchers were able to record one instance of squirting on video. In all cases, squirted fluids were blue, indicating that at least a part of the liquid consisted of urine.

To make matters more confusing, for centuries scientists and anyone willing to take a peek down there weren't percent sure where this fluid was truly coming from. Many people assumed the bladder, but in some experiments capturing and analyzing the liquid in the name of science, naturally , researchers found prostate specific antigen PSA , which is only produced by the female prostate.

Female emissions come in many forms. Women can produce several types of fluid during sex. At the arousal stage, lubricating fluid is released by the vagina. Then, as orgasm is reached, two other types of fluid can sometimes be expelled from the urethra: a milky fluid secreted in small amounts, and a clear fluid released in large volumes, often hundreds of millilitres. Until recently , both orgasm fluids were described as female ejaculation. About 5 per cent of women in Western countries are thought to experience squirting, but what the fluid is and where it comes from has been uncertain. A study led by French gynaecologist Samuel Salama , now at the Poissy Saint Germain en Laye Hospital in Paris, suggested that squirting involves the expulsion of urine from the bladder , since ultrasounds on seven women who could squirt showed their bladders were full just before squirting and empty directly afterwards. To find out for sure, Miyabi Inoue, a urologist at Miyabi Urogyne Clinic in Japan, and her colleagues injected blue dye mixed with water into the bladders of five female volunteers who could squirt.
