Pre-ejaculate, a more viscous higher flow variation
Function
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 of the foreskin over the glans. The amount of fluid that the human male issues varies widely among individuals, from imperceptible amounts to a copious flow.Presence or absence of sperm
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) among couples that practice perfect use of coitus interruptus.It is likely, however, that pre-ejaculate which follows a recent ejaculation will contain more sperm, as some ejaculate is always left in the duct after orgasm.[3]
Presence of HIV
The same studies have shown the presence of HIV, the virus responsible for the disease AIDS, in pre-ejaculate.[1]References
