A company, http://microsort.net, is offering to help with gender selection by sorting sperm prior to insemination. It's more effective to choose girls than boys, which seems appropriate since the main reason seems to avoid X-chromosme disorders that plague boys. But they also allow it for family balancing. Is this ethical? What if it leads to an imbalance in the sex ratio like India and China? Should that be up to individuals to choose? Even if it's only for balancing a family, that could happen. More might choose to balance two boys with a girl, than the other way around.
