sperm

Sperm are tiny cells made in the male body that carry genetic information. You can think of them as microscopic carriers that can join with an egg and start the process of creating a new life. In everyday English, this word is mainly used in biology, medicine, and conversations about reproduction or fertility. For example, someone might say, "He has a low sperm count," meaning the number of these cells is lower than expected. The word comes from a Greek word meaning "seed."

Sperm are the male reproductive cells that can fertilize an egg. They are extremely small and are usually seen only with a microscope. Each one carries half of the genetic information needed to create a new human being, and that information joins with the other half from the egg during fertilization.

These cells are produced in the testes and move through the male reproductive system before being released in semen. Large numbers are usually released at one time, but normally only one enters and fertilizes the egg.

In modern English, the word is mostly used in biological, medical, and educational contexts. It often appears in discussions of fertility, pregnancy, contraception, genetics, and reproductive health. You may also hear it in phrases such as "sperm count," "sperm donor," or "sperm bank."

In science and medicine, people may talk about sperm count, sperm motility, and sperm shape when checking male fertility. The word can sound technical, clinical, or personal depending on the situation, but its core meaning stays the same: a male reproductive cell involved in fertilization.
