Pre-ejaculate

[ninja]

So the job of pre-cum is to clear the urethra of harmful substances so that during ejaculation the sperm will be safer. Then does this mean that the reason for precum getting women pregnant is because the male "came" recently and still have sperm left over in his urethra which is getting released because of the precum fluid? If so then would peeing (a way of killing/causing the urethra to be uninhabitable to sperm) before sex help prevent precum pregnancy?

WikiAnswers - What is pre-cum

[DirtDriver]

From my college Human Sexuality Text Book -

" The Cowper's glands, two pea sized glands adjacent to the urethra, empty into the urethra another alkaline fluid, which serves to neutralize the acidity caused by the urethra's transport of urine. The Cowper's glands secretions are the tiny droplets that sometimes appear on the tip of the penis before ejaculation. This secretion may contain sperm left over from a previous ejaculation; therefore, it can cause pregnancy to occur even if the penis is withdrawn before ejaculation. " (Greenberg, Bruess and Conklin 2007; p.177)

So basically, the pre-ejaculate isn't an ejaculate or "pre-cum" at all. It is a fluid release from the Cowper's glands to neutralize the acid from urine in the urethra to prevent sperm from being killed off during ejaculation. The more you know!

Good information. Some clarification: There is some discussion in the research community as to whether the purpose of the fluid is to neutralize the urethra or whether it simply is lubricant to assist the glob of thick semen on its way. No one knows for certain which it actually is intended by nature to accomplish.

Warning: Coming from the Cowper's glands, pure pre-ejaculate should contain no sperm. DO NOT count on it. The male genito-urinary system always has stray sperm wandering around. This is especially true during sexual arousal. Assume that it contains sperm and can cause pregnancy.

When you each have your pants off, a condom should be on him - and vaginal spermicide in her.
