What research has been done on the fluid?
There still hasn't been enough research on the fluid (ejaculate) – partly because it's difficult to obtain adequate supplies of it for investigation. Also, large scientific funds tend to be available for life-threatening diseases rather than for sexual problems!
However, recent research suggests that perhaps the ejaculate is an alkaline liquid that isn't like urine, because it doesn't contain urea or creatinine, which are normal urinary constituents. The fluid tends to be clear coloured and allegedly doesn't stain bedclothes yellow.
Researchers have claimed that it contains some chemical ingredients similar to those produced by the male prostate – notably PSA (prostate-specific antigen). It is also said to contain two sugars: glucose and fructose.
Since 2000, an increasing number of researchers have suggested the liquid may be the secretion of Skene's glands (the paraurethral glands). These are tiny structures which lie around the female urethra (the urinary pipe).
In 2007, Viennese researcher Dr Florian Wimpissinger published an important study on two women who habitually ejaculated. (Incidentally, this surname is not some sort of joke. Dr Wimpissinger genuinely is a well-known urologist in Vienna.) He and his colleagues found that the ejaculate from these two females was chemically different from that of their urine.
In particular, it contained more prostatic acid phosphatase (PAP), more prostate-specific antigen (PSA), and also some glucose."
