Sperm on egg during fertilisation
Fertilisation. Coloured scanning electron micro- graph (SEM) of sperm on the surface of a human egg (ovum) during fertilisation. The egg has a furry surface (brown). The sperm (coloured yellow) attached to it are hair-like structures; each sperm has a head, neck, and a long tail. Here they are attempting to penetrate the thick surface of the egg that attracts the sperm and enables them to attach. The human female usually produces a single large egg, and only one of the millions of male sperm released may penetrate the egg to fuse with the egg nucleus. Once fertilised, the egg begins its process of growth into a human embryo. Magnification: x1, 600 at 5x7cm size. Magnification: x5, 500 at 8x10 inch size

EDITORS COMMENTS
This print showcases the intricate process of fertilization, capturing a moment of immense significance in human reproduction. The colored scanning electron micrograph (SEM) reveals the delicate interaction between a sperm and an egg during fertilization. The surface of the human egg, depicted in a furry brown texture, acts as a barrier that attracts and enables attachment for the hair-like structures known as sperm. Each sperm is composed of a head, neck, and long tail - visible here in vibrant yellow hues. In this image, they are seen attempting to penetrate the thick surface of the egg. It is fascinating to note that while millions of male sperm are released during ejaculation, only one will successfully fuse with the nucleus of this single large egg produced by the female. This fusion marks the beginning of an incredible journey as the fertilized egg embarks on its transformation into a human embryo. Magnified at x1,600 for 5x7cm prints or x5,500 for 8x10 inch prints, this microscopic view offers us an extraordinary glimpse into one of life's most fundamental processes. Through this photograph from Science Photo Library's collection on reproductive anatomy and biology subjects we gain insight into both our own existence and marvel at nature's remarkable intricacies.
