Coloured SEM of human sperm
Human sperm. Coloured Scanning Electron Micrograph (SEM) of several mature human sperm (also called spermatozoa). Sperm are the motile male sex cells produced in the testis. Each sperm is about 65 micrometers long and broadly divided into rounded head, neck and long tail regions. A pear-shaped head contains the nucleus and genetic material of the male needed to fertilize the female egg (ovum). The head is joined to the tail by a short neck. The sperms tail enables it to swim by whiplash movements, an action that propels it to reach the ovum. Magnification: x12, 000 at 6x4.5 inch size

EDITORS COMMENTS
This print showcases the intricate details of human sperm, captured through a Coloured Scanning Electron Micrograph (SEM). Each mature spermatozoon, also known as a sperm cell, is approximately 65 micrometers long and exhibits distinct regions: a rounded head, neck, and long tail. The pear-shaped head houses the nucleus and genetic material necessary for fertilizing the female egg. A short neck connects the head to the tail. The vibrant colors in this image bring attention to the remarkable structure of these tiny cells responsible for male fertility. With a magnification of x12,000 at a size of 6x4.5 inches, every minute feature becomes visible under scrutiny. The elongated tail plays an essential role in enabling these motile sex cells to swim towards their destination—the ovum—through whiplash movements. This incredible action propels them forward with precision and determination. Through this photograph from Science Photo Library's extensive collection on human anatomy and reproduction, we gain insight into one aspect of our complex reproductive system. It serves as a reminder that even within our bodies' microscopic realms lies extraordinary beauty waiting to be explored by scientific inquiry.
