Female ejaculation
Definition
Female ejaculation refers to the expulsion of noticeable amounts of fluid from the urethra by female humans during orgasm. The largest component of this fluid is said to be generated by Skene's glands. The fluid is said by many simply to be urine (due to stress incontinence), but others report a clear or milky fluid which emerges (sometimes with force) and has a composition similar to the fluid generated in males by the prostate gland.
Female ejaculation in post-operative transsexual women has also been reported. The source of this fluid would most likely be the remnants of the prostate gland, which is not removed during vaginoplasty.
Some studies on the subject, such as that of Gary Schubach, have been criticized for their researchers' lack of medical credentials. The subject has been studied clinically since at least the 1950s and in 1981 female ejaculation was determined to be present in at least one female by Addiego et al.
In 2002, Emmanuele Jannini of L'Aquila University in Italy showed one explanation for this phenomenon as well as for the frequent denials of its existence. Skene's gland openings are usually the size of pinholes, and vary in size from one woman to another, to the point where they appear to be missing entirely in some women. If Skene's glands are the cause of female ejaculation, this may explain the observed absence of this phenomenon in many women.
Ejaculation in women seems to be aided or caused by stimulation of the area of the vagina known as the Grafenberg spot (G-spot).
The content of the ejaculated fluid is either all urine, all ejaculate, or a combination of both. --http://en.wikipedia.org/wiki/Female_ejaculation [Dec 2004]
