It won't come as a suyprise to some, that there are markets in everything: we've recently seen that there is a market in human fat for example. But a market in menstrual blood? Yes, indeed there is and it's a company called C'elle leading it. But no, it isn't quite what you think: no one is actually selling it. The point is to collect it and store it.

For, you see, scientists have discovered that menstrual blood is rich in adult stem cells: yes, that's right, the little things that we're pretty certain are going to revolutionise medicine in the years to come. For from stem cells can be grown replacement organs (yes, this has already been shown to be possible) and who knows what else might be possible?

To find out more you can look at their FAQs or read more about C'elle. But the basic point is quite simple.

Adult stem cells are already being used to treat and cure horrible diseases: but they are usually harvested from invasive procedures like bone marrow sampling. Menstrual blood is rich in adult stem cells and can thus be a better source and this company will help you in how to collect and store it.

There truly are markets in everything.
