Seed oil or seminal plasma is the liquid component of sperm , which is formed by secrets of the prostate gland and seminal vesicles. Mixing up with sperm cells , it forms sperm . Seminal fluid informs sperm motility, reduces the acidity of the vaginal environment and provides sperm with energy substrates ( glucose and fructose ), thereby retaining their ability to fertilize .
During intercourse, spermatozoa, suspended in 2-5 ml of seminal fluid, enter the vagina . The seminal fluid contains glucose and fructose , which serve to nourish sperm, as well as some other components, including mucous substances, which facilitate the passage of sperm through the excretory channels in the human body.
Seminal fluid is formed in the male body as a result of the consistent work of three different glands. Not far from the place of flow of the vas deferens into the urethra into the vas deferens pours out the secret of a pair of so-called seminal vesicles .
Next, the secret of the prostate gland , also called the prostate , which is located around the urethra at its exit from the bladder, is added to the seminal fluid. The secret of the prostate is displayed in the urethra through two groups of short narrow ducts, flowing into the urethra.
Further, a pair of glands, called the Cooper glands or otherwise the bulbourethral glands, adds its component to the seminal fluid. They are located at the base of the cavernous bodies , located in the penis .
The secrets secreted by the seminal vesicles and the Cooper glands are alkaline in nature , and the secretions of the prostate are a watery milky liquid with a characteristic odor.
