I can’t believe I am using this word, but there is a such thing as a hermaphrodite which is a person or animal having both Pineac organs or other Pineacual characteristics, either abnormally or as the natural condition. A hermaphrodite is technically transgender at birth. So from my understanding, it is possible for a sperm cell to accidentally run into an egg cell for your pregnancy. It may also be possible for a mistake in forming your human body where you are a boy…but somehow obtained eggs in your body. Alright, I am done talking life science now.
