Life Clock and Menstruation Clock

Check out this art from Brigitte Coremans. She's got two different things going on here.

The first, Menstruation Clock, records a woman's daily temperature and records it on a seismograph-like chart each day. The result is a pretty neato fertility chart.

The second, Life Clock, is a series of beads. Each bead represents another egg that could be potentially fertilized. Each month, a bead moves from one side to the other. There are 500 "eggs" in this project--the colors change as the series progresses to show the gradual change from young to old, in a way.

Says Coremans:

"During the embryonic development of a feminine fetus, the egg cells are formed. In the twentieth pregnancy week there are approximately seven million eggs. During the further development in the uterus, a robust number goes lost, through which by the time of birth 'only' one million eggs remain. At the moment a women starts menstruation there are 400.000 left. Each menstruation cycle around 400 eggs die and only one (or two in case of a twin) will be released and can be fertilized. This process will repeat itself for an average of 40 years. "
