This story about creating sperm from stem cells (which can be either male or female stem cells) and this story about a Japanese gadget that can record and replicate smells, present a host of interesting and complicated questions about what, exactly, we think were doing with science and technology today.
I remember a Dominican priest, who taught us ethics and apologetics during my Jr. year of high school, who warned our class that before we were well into adulthood men would not be necessary to produce off-spring. We all laughed at the notion--though some of the more snarky among the girls announced that they relished the thought. I very much doubt that those snarky girls thought much about what they were saying. I doubt it about as much as I doubt that those who devise these kinds of experiments in technology think about the consequences of what they have wrought.
