Seminal fluid

Seminal fluid, also known as semen, is a complex mixture of secretions from several male reproductive organs, including the testes, prostate gland, and seminal vesicles. It serves as the vehicle for sperm during reproduction and contains a variety of substances that influence sperm function and protect sperm from the female immune system.

Composition

Seminal fluid is composed of a variety of substances, including spermatozoa, enzymes, fructose, ascorbic acid, and prostaglandins. The exact composition can vary depending on a variety of factors, including age, diet, and overall health.

Spermatozoa

The spermatozoa, or sperm cells, are the reproductive cells that are capable of fertilizing an egg to create a zygote. They are produced in the testes and make up only a small percentage of the overall volume of seminal fluid.

Enzymes

Several enzymes are present in seminal fluid, including protease, alkaline phosphatase, and lipase. These enzymes help to break down substances in the female reproductive tract, facilitating the passage of sperm.

Fructose

Fructose is a type of sugar that provides energy for the sperm cells. It is produced by the seminal vesicles and makes up a significant portion of the volume of seminal fluid.

Ascorbic Acid

Ascorbic acid, or vitamin C, is an antioxidant that protects the sperm cells from damage. It is produced by the prostate gland and is present in high concentrations in seminal fluid.

Prostaglandins

Prostaglandins are hormone-like substances that play a role in a variety of bodily functions, including the regulation of inflammation and blood flow. In seminal fluid, they help to suppress the female immune response to sperm, increasing the chances of successful fertilization.

Function

The primary function of seminal fluid is to transport sperm from the male reproductive tract to the female reproductive tract during sexual intercourse. It also provides a protective environment for the sperm, nourishing them and protecting them from the acidic environment of the female vagina.
