There's an interesting case study on this topic: David Reimer.
From Wikipedia:
David Peter Reimer (August 22, 1965 – May 4, 2004) was a Canadian man born biologically male but raised female following medical advice and intervention after his penis was accidentally destroyed during a botched circumcision in infancy.[1]
Psychologist John Money oversaw the case and reported the reassignment as successful and as evidence that gender identity is primarily learned. Academic sexologist Milton Diamond later reported that Reimer failed to identify as female since the age of 9 to 11,[2] and transitioned to living as a male at age 15. Well known in medical circles for years anonymously as the "John/Joan" case, Reimer later went public with his story to help discourage similar medical practices. He later committed suicide after suffering years of severe depression, financial instability, and a troubled marriage.[3]

Quite an interesting topic I think. I would agree with those who have said that culture, gender, and sex are different things, but I think it needs to be a personal choice to acquire or change any aspect of your identity. If someone assigns it to you, you can get situations like this.
