A sperm cells head is approximately 5 microns in diameter, its tail is approximately 50microns
Sperm cells are small, motile cells with a distinct head and a long tail. They are typically streamlined in shape to aid in swimming towards the egg for fertilization. Under a microscope, sperm cells appear to be oval-shaped with a long, whip-like flagellum.
Sperm cells have the smallest diameter of the cells mentioned if measuring at the head. However, the flagellum makes the cell appear very long.
The tail of a sperm remains with the head until the sperm goes into the egg to fertilise it.

sperm cells are microscopic so they cannot be measured but they are around 1/100000th of a millimetre
A sperm cells head is approximately 5 microns in diameter, its tail is approximately 50microns, In total, appx. 55microns (55 x 10^-6 m), that's about 25000 times smaller than a ping-pong ball.
Immature sperm cells, also known as spermatids, appear as round cells with a condensed nucleus and a small amount of cytoplasm. They are smaller and less developed compared to mature sperm cells, which have a distinct head, midpiece, and tail. Under a microscope, spermatids can be observed in various stages of spermatogenesis as they continue to mature into fully developed sperm cells.
Egg cells have receptors on their surface that can bind to chemicals like sperm. These receptors help facilitate the process of fertilization by allowing the sperm to attach to the egg cell.
The cell formed after fertilization by sperm and egg is called a zygote. A zygote is a diploid cell, meaning a cell that has two sets of chromosomes (one from egg, one from sperm).
Sperm cells are the only human cells that have a flagellum, which is a long, whip-like structure that helps the cell to move. This unique feature allows sperm cells to swim towards the egg for fertilization.
Yes, it is possible to fit over a million sperm cells on a pinhead due to their microscopic size. A single drop of semen can contain millions of sperm cells, so it is feasible for them to be placed on a pinhead, although it would be challenging to count them individually.
