A member asked:

Please explain why people say we all start out female in the womb?

A doctor has provided 1 answer

It's true!: Embryologically, if the fertilized ovum does not have a 'y' chromosome then the default program is female in all cases. If a 'y' is present, then an 'inducer substance' is generated to cause male differentiation.
