During sexual excitement, the women’s empty bladders filled up, and then, after they’d squirted, they were empty again—just as they’d been after they peed the first time. Which suggests that the women were probably releasing urine. But! There’s a caveat. The scientists also found that there was small amount of ‘prostatic secretions’—fluid from the prostate gland—in the fluid sample, which means that squirting is actually a combo of both pee and ‘prostatic secretions.’ ‘Our results lead us to conclude that squirting and the so-called ‘female ejaculation’ essentially are two distinct events,’ say the study authors.
