Human Sperm under the Microscope

Human spermatozoa (sperm) in semen under the microscope. Sperm are motile gametes that are produced by meiosis, resulting in 23 chromosomes, half of the 46 chromosomes found in all other cells in the body. If it unites with a human ovum (egg), which also has 23 chromosomes, they will combine to make 46 chromosomes and become a zygote and eventually a baby.

Human sperm swim by whipping around their flagellum which propels them forward. Fructose sugar is the main source of energy that sperm use to move around.

In the video, a lot of deformed sperm can be seen, as well as ones that don't swim well and some that look dead. It is common to have a large number of abnormal sperm cells.However, low sperm counts or high rates of abnormal sperm cells can make it very difficult for a man to get a woman pregnant.

Semen contains fructose, several enzymes, amino acids, proteins and several different components as well as sperm. This cocktail protects the sperm from the acidic vagina and helps them on the dangerous road the the egg. A man who has undergone vasectomy can still produce semen although it will not have any sperm in it.
