I don't see how. A lesbian couple using sperm created in this method wouldn't really be 'two mommies' any more than a lesbian couple using sperm from a sperm bank.

The sperm the Newcastle team have 'created' is through persuading stem cells from a male embryo to differentiate in to sperm cells. That means that the initial cells that you get the sperm from are male.

It is extremely unlikely that female stem cells (assuming you could take stem cells from an adult person and do the same thing - which is very unlikely for a variety of reasons) could do the same thing because the Y chromosome almost certainly contains necessary information for differentiating in to sperm cells, and women lack the Y chromosome.
