False-colour SEM of human seminiferous tubules
False-colour scanning electron micrograph of seminiferous tubules in the human testis (cross section), the site of production and maturation of sperm. Round undifferentiated cells lining the tubule wall (blue, pink) become sperm by halving their chromosome number, and transforming in a process which takes about two months. During this time the cells move toward the centre of the tubule and develop tails. Mature sperm migrate up the cavity of the tubule & are stored in the epididymis. 200-300 million sperm are released in an average ejaculation. Magnification: x135 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate world within the human testis, specifically focusing on the seminiferous tubules. Through false-colour scanning electron microscopy, we are granted a mesmerizing glimpse into the site where sperm production and maturation occur. The round undifferentiated cells lining the walls of these tubules, depicted in shades of blue and pink, undergo a remarkable transformation to become fully-formed sperm. This process involves halving their chromosome number and takes approximately two months to complete. As they progress towards the center of the tubule, these cells develop tails that will enable them to swim. Once matured, these extraordinary sperm migrate upwards through the cavity of the tubule before finding their temporary home in the epididymis for storage. Astonishingly, an average ejaculation releases between 200-300 million of these tiny warriors into their quest for fertilization. At a magnification level of x135 and presented in a 6x7cm size format, this image offers us an up-close look at one aspect of male reproductive anatomy - shedding light on spermatogenesis and revealing just how intricately designed our bodies are for procreation. Science Photo Library has once again captured nature's wonders with precision and artistry in this visually stunning photograph print.
