No a female seed will not turn male completely on its own but it can exhibit male traits along with female traits which would make it a hermaphrodite. It would take reversing using STS, CS or another chemical method to turn it completely male.
If you have seeds that you planted and you have a true male then the seed was a regular seed and turned out to be male. But since you haven't posted a picture of the plant in question nobody can tell you what you have.
You can also make a male plant exhibit only female traits through the use of chemicals.
