What is that, you ask? They are photos of the exact moments of ovulation in a woman, of course!
Captured so clearly for the first time by doctor Jacques Donnez at the Catholic University of Louvain (UCL) in Brussels, Belgium (while performing a partial hysterectomy), these photos are an incredibly detailed look at how humans initially start their reproductive phase of life.
The release of an egg was considered a sudden, explosive event, but his pictures, to be published in Fertility and Sterility, show it taking place over a period of at least 15 minutes.
Shortly before the egg is released, enzymes break down the tissue in the mature follicle, a fluid-filled sac on the surface of the ovary that contains the egg. This prompts the formation of a reddish protrusion, and after a while a hole appears, from which the egg emerges, surrounded by support cells. It then enters a Fallopian tube, which carries it to the uterus.
Kinda looks like a very big, juicy pimple!
