Sperm gets ejected from the penis, enters the vagina, and swims up the reproductive tract until they reach the egg to fertilize it. Barely years ago, it was considered a major scientific breakthrough when scientists came up with the idea that a fully formed, tiny human inhabited the head of each sperm — totally debunked and untrue. Fortunately, as the human body has evolved over thousands of years to maximize fertility potential, so has our scientific understanding about sperm. But many of us still believe some pretty unscientific, long-standing sperm myths.

Sex Cells Anatomy and Production

Sperm is the male reproductive cell , or gamete , in anisogamous forms of sexual reproduction forms in which there is a larger, "female" reproductive cell and a smaller, "male" one. Animals produce motile sperm with a tail known as a flagellum , which are known as spermatozoa , while some red algae and fungi produce non-motile sperm cells, known as spermatia. Sperm cells form during the process known as spermatogenesis , which in amniotes reptiles and mammals takes place in the seminiferous tubules of the testes. The spermatocytes then undergo meiosis , reducing their chromosome number by half, which produces spermatids. The spermatids then mature and, in animals, construct a tail, or flagellum, which gives rise to the mature, motile sperm cell.

Sperm cell structure Free Vector

Humans are made up of trillions of cells — the basic unit of life on earth. In this article, we explain some of the structures found in cells and describe a few of the many types of cell found in our bodies. Cells can be thought of as tiny packages that contain minute factories, warehouses, transport systems, and power plants. They function on their own, creating their own energy and self-replicating — the cell is the smallest unit of life that can replicate. However, cells also communicate with each other and connect to create a solid, well stuck-together animal.
