Human egg makes accidental debut on camera
11 June 2008
Look Closely: this is history in the making. These are the
cleareat pictures ever taken of what is the starting point
of every humen life: ovulation occurring inside a woman's
body. See the photos.
"The release of the oocyte from the ovary os a crucial
event in human reproduction," says Jacques Donnez at the
Catholic University of Louvain (UCL) in Brussels, Belgium.
"These pictures are clearly important to better understand
the mechanism."
Observing ovulation in humans is extremely rare, and previous
images have been fuzzy. Donnez captured the event by accident
while preparing to carry out a partial hysterectomy on a 45-
year-old woman. 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 ontains 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.
While there are no immediate medical implications from the
pictures, Darryl Russell, who researches reproductive health
at the University of Adelaide in Australia, says they are
remarkable: "In animals, even when we control hormone levels
- allowing us to predict the time at which ovulation will occur
- it is very rare to see it in progress."
