The terms semen and sperm are often used interchangeably, but they are not the same thing. Semen is the fluid that is released from the penis during ejaculation, while sperm are the reproductive cells that are found within semen.
Semen is composed of a mixture of fluids from different parts of the male reproductive system, including the prostate gland, the seminal vesicles, and the bulbourethral gland. These seminal fluids provide nutrients and protection for the sperm, and help transport sperm out of the body during ejaculation.
The composition of semen can vary depending on a number of factors, including age, diet, and overall health.
Sperm, on the other hand, are the reproductive cells that are produced in the testicles. They are responsible for fertilizing an egg in order to create a pregnancy. Sperm are small, elongated cells that have a tail and a head.
The head contains the genetic material (DNA) that will combine with the egg's DNA to create a new individual. The tail propels the sperm forward, allowing it to swim through the female reproductive tract and reach the egg.
Sperm production and semen production are two different processes.
It's worth noting that sperm production and semen production are two different processes. Sperm production is a continuous process that occurs in the testicles, while semen production is regulated by hormones and only occurs when a man is sexually aroused.
