ⓘ Pre-ejaculate

Pre-ejaculate is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal. It is similar in composition to semen but has distinct chemical differences. The presence of sperm in the fluid is variable from low to absent. Pre-ejaculate functions as a lubricant and an acid neutralizer.

                                     

1. Origin and composition

The fluid is discharged from the urethra of the penis during arousal, masturbation, foreplay or at an early stage during sexual intercourse, some time before the individual fully reaches orgasm and semen is ejaculated. It is primarily produced by the bulbourethral glands Cowpers glands, with the glands of Littre the mucus-secreting urethral glands also contributing. The amount of fluid that is issued varies widely among individuals. Some individuals do not produce any pre-ejaculate fluid, while others emit as much as 5 ml 0.18 imp fl oz; 0.17 US fl oz.

Pre-ejaculate contains some chemicals associated with semen, such as acid phosphatase. However, other semen markers, such as gamma-glutamyltransferase, are completely absent from pre-ejaculate fluid.

                                     

2. Function and risks

Pre-ejaculate neutralizes residual acidity in the urethra caused by urine, creating a more favorable environment for the passage of sperm. 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. Pre-ejaculate also acts as a lubricant during sexual activity, and plays a role in semen coagulation.

Low levels or no sperm exists in pre-ejaculate, although studies examined small samples of men. Two contrary studies found mixed evidence, including individual cases of a high sperm concentration. Popular belief – dating to a 1966 Masters and Johnson study – 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. However, pre-ejaculate is ineffectual at causing pregnancy.

Studies have demonstrated the presence of HIV in most pre-ejaculate samples from infected men.

                                     

3. Overproduction

In rare cases, an individual may produce an excessive amount of pre-ejaculate fluid that can be a cause of embarrassment or irritation. A few case reports have indicated satisfactory results when such individuals are treated with a 5-alpha-reductase inhibitor, such as finasteride.
