Is the fluid that comes out when you have "sexual desire" is it semen or prostatic fluid?
Many people will encounter this situation, watch "adult videos," or start "sexual arousal" at certain special moments, and the penis will not be honestly erected.
When I wanted to do something further, I hadn't stimulated the penis too much, but some transparent liquid flowed out from the glans.
Some friends with little sexual experience will think, is this semen I had ejaculated before exercising much? I wouldn't be premature ejaculation.
And men with some experience think it should be prostatic fluid, nothing unusual. Just wear a condom before ejaculating.
I am here to tell you that neither statement is true!
This is normal, but it's not ejaculation, so it's not premature ejaculation. Friends who are worried about their premature ejaculation can rest assured.
And I want to tell the "experienced drivers" that there may also be sperm in it, so you must wear a condom early, or be careful!
So what is this mysterious liquid?
Let's find out first.
What are semen and prostatic fluid?
Semen
Semen refers to the fluid that a man ejaculates from the urethra during ejaculation. Normal semen is a viscous liquid mixture consisting of sperm and seminal plasma, which makes up more than 90% of the semen volume.
Sperm are produced in the testes, mature in the epididymis, and exit through the vas deferens.
Seminal plasma is mainly a mixed fluid secreted by accessory glands such as the prostate, seminal vesicles, bulbourethral glands, and a small amount of testicular fluid and epididymal fluid.
Usually, sperm and seminal plasma are stored in different locations. During the ejaculation process, sperm and seminal plasma will mix to form semen.
prostatic fluid
The prostate gland is an accessory gland of the male reproductive system. It is an unpaired solid gland. It is located between the bladder and the urogenital diaphragm and surrounds the root of the urethra. Its shape and size are similar to a slightly flat chestnut.
Prostatic fluid is a thin, colorless emulsion secreted by prostate epithelial cells, which is weakly acidic.
Male hormones control the secretion of prostatic fluid, and the daily secretion is about 0.5 to 2 ml.
The protein content in a prostatic fluid is minimal, mainly containing high concentrations of zinc ions, acid phosphatase, proteolytic enzymes, fibrinase, spermine, aliphatic polypeptides, etc. Among them, proteolytic enzymes and fibrinases can promote semen liquefaction.
What is this mysterious liquid?
So, having said all that, what is this mysterious liquid flowing out?
It is neither semen nor prostatic fluid.
Academically, this gadget is called pre-ejaculate (also known as pre-ejaculate, Cowper's fluid, commonly known as first-going fluid) because it is mainly secreted by the male urethral gland (Cowper's Gland), so it is also called bulbourethral gland fluid. In addition, pre-ejaculate contains a small number of secretions from the mucous glands of the urethra.
Therefore, the transparent fluid that flows out of the urethral opening during sexual arousal is more appropriate to call the bulbourethral gland fluid.
The bulbourethral glands are a pair of pea-sized male accessory glands, brownish-yellow, about 1cm in diameter, located in the deep perineal space between the urethral sphincter or deep, transverse perineal muscle bundles, just posterolaterally above the base of the bulbourethral.
Semen ejaculation is a multi-step process, mainly divided into three steps:
1. The initial early discharge is transparent and viscous, containing only a tiny amount of prostatic fluid and a small number of sperm, mainly the secretions of the urethral glands and bulbourethral glands, which lubricate the urethra and facilitate ejaculation, and often do not coagulate;
2. Next is the central part of ejaculation, mainly prostatic fluid and epididymal tail fluid. The quantity of sperm is high, and the quality is high. It is a semen-rich discharge. After discharge, it coagulates first and then melts;
3. The last ejaculate is post-sperm discharge, mainly seminal vesicle and ampulla secretions, very little prostatic fluid, primarily rich in fructose, and very little sperm.
Seeing this, everyone should understand!
remind bulbourethral gland fluid ≠prostatic fluid ≠semen
Don't confuse the three
And one more thing
According to research, the secretion of bulbourethral gland fluid will increase significantly during male sexual excitement and masturbation, before and during sexual intercourse.
However, the amount of secretion varies from person to person. Some people may only secrete a few drops or even no secretion; some people secrete so much that even their underwear can get wet, and some data show that some people can even secrete as much as 58ml.
The secreted bulbourethral gland fluid may contain a small amount of sperm, more likely to occur after the first ejaculation without urination.

Therefore, condoms should be used throughout sexual intercourse.
