Close-up of pre-ejaculate

Pre-ejaculate, also known as pre-cum, is a clear, colorless, and viscous fluid that is secreted by the bulbourethral glands (also known as Cowper's glands) in males. This fluid is released during sexual arousal, prior to ejaculation.

Function

The primary function of pre-ejaculate is to neutralize the acidity of the urethra and vagina, providing a more favorable environment for sperm to travel. The fluid helps to lubricate the urethra for the passage of sperm during ejaculation and may also help to flush out any residual urine or foreign matter.

Composition

Pre-ejaculate is composed mainly of mucus, which is secreted by the bulbourethral glands. It may contain small amounts of spermatozoa, although the concentration is typically much lower than that found in semen. The presence of sperm in pre-ejaculate can vary among individuals.

Role in Fertility

While pre-ejaculate itself is not intended to carry sperm, there is a possibility that it can contain viable sperm from a previous ejaculation. This can occur if sperm remain in the urethra and are carried out with the pre-ejaculate. As a result, there is a potential, albeit low, risk of pregnancy from pre-ejaculate.

Health Considerations

Pre-ejaculate can also play a role in the transmission of sexually transmitted infections (STIs). Since it can contain pathogens, it is important to use barrier methods such as condoms to reduce the risk of STI transmission during sexual activity.
