Human sperm cells, SEM
Sperm cells. Coloured scanning electron micrograph (SEM) of human sperm cells or spermatozoa. These tiny male sex cells are produced in the testes, and are responsible for fertilisation of the female egg (ovum). They have a rounded head that contains the male hereditary material (DNA), and a long tail that are used for propulsion. The sperm cell at lower right has some residual cytoplasm seen behind its head, which may affect its motility or fertility. All men have some deformed sperm, but this is not a problem unless their numbers rise. Magnification: x2150 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate beauty of human sperm cells. In this coloured scanning electron micrograph (SEM), we are granted a close-up view of these tiny male sex cells, responsible for the miraculous process of fertilisation. Produced in the testes, each spermatozoon possesses a rounded head containing vital genetic material (DNA) and a long tail that propels it towards its destination. While most sperm cells appear perfectly formed, one can observe an anomaly in the lower right corner. This particular cell retains some residual cytoplasm behind its head, which may potentially impact its motility or fertility. It serves as a reminder that all men possess some deformed sperm; however, unless their numbers increase significantly, it does not pose any concern. The magnification level employed to capture this image is an astounding x2150 at 6x7cm size. Through this lens, we gain insight into the complex world within our reproductive system and marvel at nature's intricacies. This photograph from Science Photo Library offers more than just aesthetic appeal; it provides valuable scientific knowledge about human biology and reproduction. Its vibrant colours and meticulous details invite us to contemplate the wonders occurring within our own bodies – reminding us of both our fragility and resilience as living beings.
