Pre-ejaculate
From Wikipedia, the free encyclopedia
Pre-ejaculate (also known as pre-ejaculatory fluid or Cowper's fluid, and colloquially as precum) is the clear fluid that is issued from a man's penis when he is sexually aroused. The fluid is usually secreted by Cowper's glands during masturbation, foreplay or at an early stage during sex, some time before the man fully reaches orgasm and semen is ejaculated.

[edit] Purpose
Pre-ejaculatory fluid prepares the urethra for the passage of semen by neutralizing acidity due to any residual urine. It also lubricates the movement of the penis and the foreskin over the glans. The amount of fluid that the human male can issue varies widely between individuals, from imperceptible amounts to a copious flow.
[edit] Components
There have been no large-scale studies of sperm in pre-ejaculate, but some smaller-scale studies suggest that any sperm present may be ineffectual at causing pregnancy.[1][2] This may account for the surprisingly low pregnancy rate (approximately 4% per year) amoung couples that practice perfect use of coitus interruptus.
A more serious problem is those same studies have shown the presence of HIV, the virus responsible for the disease AIDS, in pre-ejaculate.[1]
[edit] Colloquialisms
Slang terms for pre-ejaculate include pre-come, pre-cum, rewetting solution, sex slime, dog water, goop, frutiopia, speed drop, love drops, clear stuff, quick-slick-dick-trick and slickener.
