Nature of the fluid
Studies have been done by Beverly Whipple, John Perry, Gary Schuback, Milan Zaviacic and Cabello Santamaria but their findings are limited. While current information offers no solid information about the source of the fluid, chemical analysis performed on the fluid has revealed that while it sometimes contains at least traces of urine, it regularly contains chemical markers unique to the prostate (whether male or female).
The latest research indicates the possibility that all women produce female ejaculate, even if they are not aware of it:
- The expelled or released fluid is not urine, it is an alkaline liquid secreted by the paraurethral (alongside the urethra) glands.
- The paraurethral glands produce an enzyme called prostatic acid phosphatase (PAP), along with prostate-specific antigen (PSA).
- Skene's gland also produces Human Protein 1, a trait formerly believed to be unique to the male prostate.
Studies have found that:
- 54-60% of women have experienced emission of fluid at orgasm,
- with 6% reporting that they regularly ejaculate in a forceful manner, and
- an additional 13% stating that they have done so infrequently.
Dr. Shubach believes that "most women, the overwhelming proportion of women" are capable of ejaculation
Medical Thoughts From the 1700's
Throughout time there have been numerous reports of the expulsion of fluids from the vagina by women during sexual arousal and/or orgasm. There are references to this by historical scientific figures such as Aristotle and Galen, discussing and identifying vaginal expulsions which did not have the appearance or smell of urine, and did not stain.
The first modern description of both female genitalia and the matter of vaginal expulsions came from the 17th century Dutch physician, Reinier De Graaf, who in 1672 stated: "The urethra is lined internally by a thin membrane. In the lower part, near the outlet of the urinary passage, this membrane is pierced by large ducts, or lacunae, through which pituito-serous matter occasionally discharges in considerable quantities. Between this very thin membrane and the fleshy fibres we have just described there is, along the whole duct of the urethra, a whitish, membranous substance about one finger-breadth thick which completely surrounds the urethral canal. This substance could be called the "female prostatae".
De Graaf's description of the prostatae in women in reference to the glands surrounding the female urethra represented conventional medical thought for almost 200 years.
