Collapsed ovarian follicle, SEM
Collapsed ovarian follicle. Coloured scanning electron micrograph (SEM) of an ovarian follicle just after ovulation (release of an egg). The central lumen is filled with red blood cells (yellow) from a collapsed blood vessel. Surrounding the lumen are cuboidal follicular cells (blue). The follicle will form into the corpus luteum, or yellow body. The function of the corpus luteum is to secrete the hormone progesterone to ready the uterus for the implantation of a fertilised egg. If the egg is not fertilised it stops secreting and degrades after roughly 12 days

EDITORS COMMENTS
This print showcases the intricate details of a collapsed ovarian follicle, captured using a scanning electron microscope (SEM). The image reveals the aftermath of ovulation, where an egg has been released from the follicle. The central lumen is filled with red blood cells, appearing as a vibrant yellow hue due to false coloring. Surrounding the lumen are cuboidal follicular cells, depicted in striking blue tones. This fascinating structure will transform into what is known as the corpus luteum or yellow body. Its primary role is to secrete progesterone hormone, which prepares the uterus for potential implantation of a fertilized egg. However, if fertilization does not occur within approximately 12 days, this remarkable corpus luteum ceases its secretion and begins to degrade. It highlights nature's delicate balance and adaptability within our reproductive system. Through this mesmerizing photograph, we gain insight into the complex workings of female biology and reproduction. It serves as a testament to both scientific curiosity and technological advancements that enable us to explore these microscopic wonders hidden within our own bodies. Captured by Science Photo Library's skilled photographers and scientists, this image invites contemplation on the beauty and intricacy found in even the tiniest aspects of human anatomy.
