Pre-ejaculate

from Wikipedia, the free encyclopedia
Escaping pre-ejaculate

The pre-ejaculate (from Latin prae “before” and eiaculari “to throw out”; colloquially also pleasure drops , longing drops or pre-juice ) is a glandular secretion that can be secreted during sexual arousal and then exits the penis before ejaculation . In addition to other functions, it serves as a natural lubricant during sexual intercourse , just like the vaginal secretions of women. The pleasure drop can contain sperm and lead to pregnancy.

features

It is a secretion of the Bulbourethral gland (also Cowper's gland ), which consists of a clear mucus from different types of gland cells.

A study from 2011 showed that in a significant proportion of healthy sexually mature men there are motile sperm in the pre-ejaculate even if no ejaculation has previously taken place. Whether the intermittent flushing of the urethra by urinating has an effect on the amount of sperm in the pre-ejaculate was not investigated. Upon contact with the vagina , the secretion can lead to fertilization and ultimately pregnancy .

Earlier studies had shown that there are usually no sperm in the pre-ejaculate, unless ejaculation took place shortly beforehand, or in the event of anatomical deviations or diseases. In such cases, the pre-ejaculate could already contain some sperm when sexual arousal was renewed and thus lead to fertilization and ultimately pregnancy if it came into contact with the vagina . Allegedly, with some probability, the sperm remaining in the urethra from a previous ejaculation were eliminated by subsequent urination.

The amount of secretion released can vary greatly from person to person. Some men do not pre-ejaculate, while some can produce up to 5 ml.

function

The pleasure drop is used to clean the urethra before an expected ejaculation, whereby the pH value of the urethra increases and the acidic environment is converted into an alkaline one. This secretion also acts as a natural lubricant during sexual intercourse.

Disease transmission

The bulbourethral gland and thus its secretion also play a clinical role, because when the posterior urethra ( urethritis gonorrhoica posterior ) is affected by Neisseria gonorrhoeae , the pathogens causing gonorrhea ( gonorrhea ), inflammation ( cowperitis ), abscesses ( cowper's abscess ) and strictures of the urethra ( Cowper's stricture ) can trigger. Non-gonorrheic inflammation of the urethra - caused by mycoplasma , chlamydia or fungi - can also spread to the bulbourethral glands. It cannot therefore be ruled out that these diseases can also be transmitted through the glandular secretion and the pathogens it contains.

With regard to the possibility of HIV transmission through pleasure drops during penetrating sexual intercourse or oral intercourse without sperm getting into the body, there is no reliable knowledge about the amount of virus that may be contained in this glandular secretion or about the risk of infection . Only in two studies was it possible to detect nonpermatic cells in the pre-ejaculate that contained functioning HI viruses.
