Semen and sperm are two terms that are often used interchangeably, but they are not the same thing. Semen is a whitish fluid that comes out of the penis when a person ejaculates, while sperm are male reproductive cells and are just one component of semen. Semen is actually a combination of mature sperm and fluids from the prostate, the seminal vesicles, and bulbourethral glands. This cocktail is chock-full of ingredients, including sugars, proteins, and even some vitamins and minerals. Semen is essential to sperm motility (self-movement) and helps sperm get to the egg for the purpose of procreation.

Here are some key differences between semen and sperm:

• Semen is a fluid that carries sperm cells and is ejaculated from the penis during sexual activity, while sperm are male reproductive cells that are produced in the testes.
• Semen is a combination of mature sperm and fluids from the prostate, the seminal vesicles, and bulbourethral glands, while sperm are just one component of semen.
• Semen is essential to sperm motility and helps sperm get to the egg for the purpose of procreation.

It is important to note that semen and sperm are not the same thing, and that semen is necessary for sperm to be able to fertilize an egg.
