Apostate prophet tries to be balanced; multiple male marriages?

In answer to the video "10 Reasons to Reject Islam"

As a side issue, one might ask why the regulation doesnt apply to women as well (polyandry). Aside from the basic issues of uncertain descendancy, a woman becomes undisposed to satisfy the most basic physical or sexual needs of her multiple husbands. IT is the case during her menstrual period or while pregnant. Also, from a strict biological viewpoint, a woman can only carry and conceive one child at a time and from one man only, for nine months before she can conceive another. A man on the other hand can beget a child every time he cohabits with a woman. Polyandry opposes these very elementary socio-biological issues. That is why it is practiced by very few societies that seek to limit population growth, with a purely materialistic outlook. For example, polyandry in the Himalayan mountains is related to the scarcity of land. The marriage of all brothers in a family to the same wife allows family land to remain intact and undivided.
