Female ejaculation is characterized as an expulsion of fluid from the Skene's gland at the lower end of the urethra during or before an orgasm. It is also known colloquially as squirting or gushing , although research indicates that female ejaculation and squirting are different phenomena, with squirting being attributed to a sudden expulsion of liquid that partly comes from the bladder and contains urine. There have been few studies on female ejaculation. Much of the research into the composition of the fluid focuses on determining whether it is, or contains, urine. Whether the fluid is secreted by the Skene's gland through and around the urethra has also been a topic of discussion; while the exact source and nature of the fluid remain controversial among medical professionals, and are related to doubts over the existence of the G-spot , [8] [9] [7] there is substantial evidence that the Skene's gland is the source of female ejaculation.
