Seminal fluid
Seminal Fluid
Seminal fluid (pronunciation: /ˈsɛmɪnəl ˈfluːɪd/), also known as semen, is a complex mixture of secretions from several male reproductive organs. The primary components of seminal fluid are spermatozoa and seminal plasma.
Etymology
The term "seminal" comes from the Latin word "semen", which means "seed". The term "fluid" comes from the Latin word "fluidus", which means "flowing".
Composition
Seminal fluid is composed of spermatozoa and seminal plasma. Spermatozoa, or sperm, are the male reproductive cells. Seminal plasma, on the other hand, is a mixture of secretions from the seminal vesicles, prostate gland, and bulbourethral glands.
The seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen. The prostate gland secretes a thin, milky fluid that constitutes about 30% of the total semen volume. The bulbourethral glands secrete a clear mucus that helps to lubricate the urethra and neutralize any acidity due to residual traces of urine.
Function
The primary function of seminal fluid is to transport sperm from the male reproductive tract to the female reproductive tract during sexual intercourse. The components of seminal fluid also nourish the sperm, protect them from the acidic environment of the vagina, and enhance their ability to fertilize the egg.
