The release of lubricant on arousal is a natural process on the bodies of women and men.
Male lubrication, or pre-ejaculation, refers to one of the healthy secretions of the male body. Pre-ejaculation is excreted through a special organ called the urethra, also known as the urethra. Through this duct, which is a narrow tube, urinary tract secretions from the bladder and semen (ejaculation) flow. This fluid passes through the urethra before exiting through the urethral opening at the head of the penis.
What is it and how is it formed?
Pre-ejaculation, pre-seminal fluid, or pre-seminal fluid, is the secretion product of the bulbourethral gland (Cooper), which is similar to thick, viscous transparent mucus. The Cooper gland, the size of a pea, is a paired organ and is located just below the prostate gland (prostate), at the base of the penis. It should be noted that the Cooper gland is precisely responsible for precum secretion, while spermatogenesis, that is, the formation of sperm, occurs in the testis (testis).
When a man experiences sexual stimulation or penile stimulation, for example during masturbation, the bulbourethral glands are able to secrete an average of 4 milliliters of pre-ejaculation into the urethra, which is about the amount of one teaspoon.
However, the amount of fluid released is very individual: in some cases, it may be only a few drops, in others - an annoying advantage. Pre-ejaculatory "excessive production" is hardly a concern: several studies show that the use of 5-alpha-reductase (5-ARI) inhibitors successfully normalizes Cooper gland secretion.
What are the properties of lubricants for men?
Pre-seminal fluid has an important function in the male body and has several properties, knowledge of which will help in having safe sex.
Pre-ejaculation as a natural lubricant
One of the most important functions of pre-ejaculation is to lubricate the penile glands during sexual intercourse and ejaculation. Pre-seed lubricates the urethra and, due to its alkaline composition, protects the urethral mucosa from urine and other irritating elements. This allows the sperm to come out freely through the urethra and release through the head of the penis. Pre-ejaculation neutralizes the level of acidity not only in the urethra, but also in the vagina, which is acidic and therefore an unfavorable environment for sperm.
Pre-ejaculation contains semen
Despite the fact that pre-ejaculation and semen are different secretions from different organs, a certain percentage of "live" sperm can still be contained in pre-ejaculation.
Well-known sex researchers William Masters and Virginia Johnson (popularized through the TV series "Masters of Sex") were among the first to draw this conclusion in the 1960s. However, their conclusions are not substantiated by experimental data. In 2011, British scientists filled this scientific gap when they tested a group of volunteers and found active sperm in four out of ten pre-ejaculatory samples taken. While it is true that in some cases, the presence of sperm in the premature part has been confirmed, in other samples it is not known at all.
The scientific debate on the causes of sperm in the premature part is ongoing. Some researchers explain this phenomenon by residual ejaculation (sperm) in the urethra from previous intercourse. Others support the theory that sperm enter pre-ejaculation shortly before or before ejaculation. However, it is also believed that volunteers who participated in experiments that confirmed the presence of sperm in pre-sperm simply took their samples incorrectly.
Pre-ejaculation can lead to pregnancy
As mentioned above, active sperm is indeed part of pre-ejaculation. Moreover, some pre-sperm samples contain up to 23 million sperm-enough for fertilization and fertilization.
Although the presence of sperm in pre-ejaculation is very individual and the overall probability of pregnancy from pre-ejaculatory fluid is generally low, the practice of protective methods such as intercourse disorders (coitus interruptus) still runs the risk of unwanted pregnancies. According to statistics, pregnancy occurs in 27 percent of couples who use contraceptives regularly.
Pre-ejaculation carries an infection
Pre-seminal fluid is a carrier of viruses and bacteria. For this reason, the use of interrupted sex will not protect against sexually transmitted infections, including HIV, chlamydia, gonorrhea, and other diseases.
Pre-ejaculation is rarely controlled
For most men, the process of pre-ejaculatory excretion is uncontrolled. Therefore, to reduce the risk of unwanted pregnancies, it is recommended to use uninterrupted intercourse, as well as other methods of contraception, such as condoms or intrauterine devices.
