Female ejaculation, also known as gushing or squirting, is an expulsion of liquid from a person’s vagina or their urethra, often (but not always) accompanying orgasm. Much like the existence of the G-spot, there has been much debate around how female ejaculation is produced and what exactly it is. There are at least three different secretions that can be classified as female ejaculation: liquid that is secreted from the Skene’s Gland (also known as the female prostate); liquid that is secreted from the urethra; and lubricant that is secreted from the vagina. Research on female ejaculation and the terminology used by journalists and bloggers has not come to a consensus on what female ejaculation is, how it is produced, or what matter it consists of, except that it is not solely urine and is not a byproduct of incontinence.
One of the earliest contemporary studies done on female ejaculation was “Subjective reports of female orgasmic expulsion of fluid” by Bullough, B et. al. in 1984. Out of the 227 women interviewed, 54% reported that they had experienced ejaculation at least once, although the study did not delve into the material makeup of female ejaculate. However, the previous year in 1983, Goldberg et. al. studied the fluid produced by female orgasms and found that it "appeared similar in biochemical properties to urine.” The researchers "failed to detect elevated levels of prostatic acid phosphatase.” In 1989, while the existence of the G-spot was still in question, Davidson Sr et. al. ran an empirical analysis of 2,350 women, of which there was a 56% return rate, studying the relationship of G-spot stimulation to orgasm and ejaculation. They found that women who self-reported G-spot orgasm also self-reported ejaculation. In 2007, Wimpissinger et. al. concluded that the female prostate (the G-spot) causes female ejaculation.
In 2022, Pastor & Chmel reviewed the literature surrounding female orgasms and female ejaculation using the Web of Knowledge and MEDLINE, dating from 1946 to 2021. Their review found that female ejaculation and squirting are different mechanisms, originating in different areas of the vulva, and caused by different processes. Female ejaculation, they concluded, orginated in the paraurethral glands (Skene’s Gland) and produced only a few mililitres of thick fluid, which contains a high concentration of prostate-specific antigen (PSA). Squirting results in urine-type liquid secreted from the bladder.
According to some researchers like urologist Rena Malik, squirting produces both urine and PSA as found in female ejaculation.
