In the early 1980s, American sexologist Beverly Whipple, and then other scientists, conducted a scientific study of the excreted fluids and established their partial renal origin. However, urine chemical elements such as urea and creatine were present in extremely small amounts. In addition, other components not normally found in urine were also detected, among which was prostate-specific antigen (PSA).
In men, PSA is produced by the prostate gland. In women, a similar tissue is also present in the female body – these are the paraurethral glands, which are located on the anterior wall of the vagina. Studies indicate that these glands are connected to the lower urethra through the ducts. Some experts believe that these glands play a key role in producing the fluid secreted during squirting.
One day, even a curious experiment was set up in a clinical setting. Seven women capable of squirting were invited. Before they had sex with their partners they were given an ultrasound, which showed that their bladders were empty. Then, as they approached climax, there was another scan and this time the ultrasound revealed that the bladders had filled. And the third ultrasound was done after full-blown squirting and revealed that the bladders of the young ladies were empty again. Their ejaculate was collected and analyzed. It turned out that the collected material contains both creatine and urine, characteristic for the presence in normal urine, but, in addition to them, there was found PSA, which previously in standard urological tests did not appear in standard urological tests. Which means… it ended up there directly at the time of the squirt.
Women who regularly practice squirting orgasm, claim that the liquid at the exit does not smell like urine at all, and its color is different.
