2 different functions...

Menstruation and Ovulation are two separate biological functions (thus the two different medical terms) that, in the modern sense, is blurred into being the same phenomena.

Fruitarians I've met in the 70's lost their menses (at least in terms of blood), but still got pregnant.

There is strong evidence for the LACK of minerals in the modern diet and the increase of menses, and premature births.

The question is: with this modern world and pollution - that even with a properly functioning body - if we still get a proper mineral balance in our constitution.
