Researchers have recently discovered that a person's gender may not be as set in stone as we thought. Up until recently, it has been believed that once a person was born that their gender was set (barring surgical procedures that really are merely cosmetic changes). However, the discovery of a certain gene, FoxL2, has shown that this may not be the case. The FoxL2 gene seems to control whether a person develops male or female sexual organs and, surprisingly, its activity is still important into adulthood. It was found that when the gene was turned off in adult female mice their ovarian cells would begin to change into testicular cells. Scientists believe that this suggests the same could be true in humans.
