What is female squirting exactly? Well ladies, you know that fluid you sometimes squirt during sexy time?

Squirting fluid was found to consist mainly of urine but often accompanied by a liquid secreted from the female prostate. Squirting refers to the expulsion of liquid by a woman during an orgasm. Although the phenomenon has been known for a very long time — it is mentioned in Chinese Taoist texts of the 4th century — the mechanism of squirting is still poorly understood. Now, Dr. They managed to visually record the process of liquid expulsion by a sexually stimulated woman. 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.

Urologists in Japan wanted to get to the bottom of a long-held sex debate — when a woman squirts, is the fluid that is released urine, or something else? To find out, they conducted an experiment that involved injecting an indigo-colored liquid into five women's bladders. Two of the women were in their 30s, two were in their 40s, and one was in her 50s, and all of them said they had previously squirted in past sexual encounters. Unlike vaginal lubrication, where a person's vagina secretes a white and milky fluid when they're aroused, squirting involves a clear and odorless fluid. Squirting can happen before, during, or after an orgasm and has a geyser-like quality, sex educator Marla Renee Stewart previously told Cosmopolitan. After the doctors drained excess urine from each woman's bladder using a urethral catheter, they injected them with 50 milliliters of a blue-dyed saline solution. In another room, women received manual penetration from a male subject the doctors recruited. They instructed the man to use his fingers and penis "in a way to facilitate squirting. When each of the five women squirted, the doctors saw blue liquid come out of their genital areas in videos that captured the experiment. Their findings suggest the liquid women produce when they squirt comes, at least in part, from the bladder, the urologists wrote in their August 24 paper published in the International Journal of Urology. There's little research on squirting and how it actually works, but evidence suggests it's related to specific glands in the urethral sponge , which is embedded in a person's vaginal walls and part of the urination process, Mind Body Green previously reported. Researchers have long debated whether squirting liquid contains pee, or if it's a substance all on its own. To test this, the urologists who conducted the experiment tested and found PSA levels in the liquid each woman secreted during penetration. PSA is a chemical found in semen , and some researchers believe it's evidence that squirting fluid is not in fact pee, but a substance related to arousal.

Five women between 30 and 60 years old and able to squirt participated, on a voluntary basis, in the study of Inoue and colleagues. One Woman Claims To Have…. All Books We Love.

Japanese researchers writing in the International Journal of Urology have made strides in helping settle a long-standing sexological debate: The clear fluid that some people with vaginas have been known to squirt during sexual stimulation is, for the most part, just pee. This is slightly different than female ejaculation , which some experts have defined as a thick, milky fluid secreted by the female prostate also known as Skene's glands , though female ejaculate is a term often used interchangeably for squirting. 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. These two glands sit on either side of the urethra, so it makes a little sense why this has been hard to suss out. However, people have known about squirting since long before Jesus was born. The Greek philosopher Pythagoras and Hippocrates, the "father of medicine," both inaccurately described female discharges as "semen.

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. A male volunteer then sexually stimulated the women until they squirted and a researcher caught the ejected liquid in a sterile cup.

So, contrary to what you may think, not everyone is doing it. The amount of urine depends on when the person peed last and how hydrated they are, New York University sex researcher Zhana Vrangalova told Mind Body Green. This was followed by a blue-dyed saline solution that was flushed back up into the bladder. Now, Dr. Urologists in Japan wanted to understand what's in squirting fluid.

After the doctors drained excess urine from each woman's bladder using a urethral catheter, they injected them with 50 milliliters of a blue-dyed saline solution. To recap: female ejaculation, squirting, urinating and coital urinary incontinence are all separate acts. Three of the five women were able to squirt with masturbation alone, the other two needed to call in male reinforcements. The description of the experiment sounds notably uncomfortable, as it involved an ultrasound probe inserted into the man's rectum used to measure contractions in the bladder. While their partners were happy to help, researchers tried to make sure the male partners didn't ejaculate, which would make it less likely they contaminated the result. Sexual stimulation was done manually by the participant in 3 cases or through sexual intercourse with a male sex partner in 2 cases. Now, Dr.
