Pre-ejaculate on the glans of the penis

Pre-ejaculate (also known as pre-ejaculatory fluid, pre-seminal fluid or Cowper's fluid, and colloquially as pre-cum)[1] is a clear, colorless, very slippery liquid that is produced by the Cowper's glands. [2] and discharged from the urethra of males. It collects under the foreskin in the preputial sac of normal, foreskinned males where it functions as a lubricant at times of sexual arousal, masturbation or sexual intercourse. They are also called the bulbo-urethral glands and are the male equivalent of the Bartholin's Glands.[1]

Function and risks

(The following text or part of it is quoted from the free Wikipedia article Pre-ejaculate: Function and risks:)
Pre-ejaculate neutralizes residual acidity in the urethra caused by urine, creating a more favorable environment for the passage of sperm.[3] The vagina is normally acidic, so the deposit of pre-ejaculate before the emission of semen may change the vaginal environment to promote sperm survival.[4] Pre-ejaculate also acts as a lubricant during sexual activity,[4] and plays a role in semen coagulation.[4]

Low levels or no sperm exists in pre-ejaculate, although studies examined small samples of men.[5][6] Two contrary studies found mixed evidence, including individual cases of a high sperm concentration.[7][8] Popular belief  — dating to a 1966 Masters and Johnson study[9]  — stated that pre-ejaculate may contain sperm that can cause pregnancy, which is a common basis of argument against the use of coitus interruptus (withdrawal) as a contraceptive method.[5][6]

Studies have demonstrated the presence of HIV in most pre-ejaculate samples from infected men.[6][10][11]

Distribution

Sexually aroused men tend to secrete pre-ejaculate, which may be distinguished by its slippery quality.

The quantity of pre-ejaculate produced various widely between individuals. Some observers believe that, on average, foreskinned males tend to produce more pre-ejaculate than circumcised males,[12] apparently due to the superior sexual sensation received by the autonomic nervous system from the ridged band, frenulum, and other nerves of the foreskin. Restored men report increased production of pre-ejaculate after restoration.[13]

Production of pre-ejaculate may be triggered by erotic thoughts alone.
