False-colour SEM of sperm on a human egg
Fertilisation. False-colour scanning electron micrograph of sperm (blue) on a human egg. In order to fertilise the egg a spermatozoon must penetrate the thick layer of follicular cells (pink), called the corona radiata, and the inner membrane known as zona pellucida (not seen here). The penetration occurs thanks to special enzymes released by the sperms head. Once a spermatozoon ruptures the zona pellucida a chemical reaction strenghtens the two membranes. This prevents the entrance of other sperm, avoiding the creation of embryos with more than 46 chromosomes. Magnification: x910 at 6x7cm size. Magnification: x1405 at 4x5inch size

EDITORS COMMENTS
This print showcases the intricate process of fertilization, capturing a false-color scanning electron micrograph of sperm on a human egg. The image reveals the remarkable journey that a spermatozoon undertakes to successfully fertilize an egg. In order to achieve this, the sperm must navigate through multiple barriers. The first challenge is penetrating the thick layer of follicular cells known as the corona radiata, depicted in delicate shades of pink. Once accomplished, the spermatozoon then encounters another protective membrane called zona pellucida (not visible in this image). This inner membrane requires special enzymes released by the sperms' head for penetration. Upon rupturing the zona pellucida, a chemical reaction occurs between these two membranes, fortifying them and preventing other sperm from entering. This crucial mechanism ensures that only one sperm can fertilize an egg, maintaining chromosomal integrity with precisely 46 chromosomes. At magnifications of x910 at 6x7cm size and x1405 at 4x5inch size respectively, this stunning photograph offers us an up-close glimpse into one of nature's most awe-inspiring processes – human reproduction. It serves as a testament to both our curiosity about life's beginnings and our ever-advancing understanding of reproductive anatomy. Captured by Science Photo Library and presented here without any commercial intent or association with any company, this print invites contemplation on the beauty and complexity inherent in every new life created through fertilization.
